ISO/IEC 17025 Accreditation Falls Short for Cannabis Testing Laboratories

What is the role of the Quality Control (QC) Laboratory?

The Quality Control (QC) laboratory serves as one of the most critical functions in consumer product manufacturing. The QC laboratory has the final say on product release based on adherence to established product specifications. Specifications establish a set of criteria to which a product should conform to be considered acceptable for its intended use. Specifications are proposed, justified and approved as part of an overall strategy to ensure the quality, safety, and consistency of consumer products. Subsequently, the quality of consumer products is determined by design, development, Good Manufacturing Practice (GMP) controls, product and process validations, and the specifications applied throughout product development and manufacturing. These specifications are specifically the validated test methods and procedures and the established acceptance criteria for product release and throughout shelf life/stability studies.

The Code of Federal Regulations, 21 CFR Part 211, Good Manufacturing Practice for Finished Pharmaceuticals, provides the minimum requirements for the manufacture of safe products that are consumed by humans or animals. More specifically, 21 CFR Part 211: Subpart I-Laboratory Controls, outlines the requirements and expectations for the quality control laboratory and drug product testing. Additionally, 21 CFR Part 117, Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based Preventative Controls for Human Food: Subpart B-Processes and Controls states that appropriate QC operations must be implemented to ensure food products are safe for consumption and food packing materials and components are safe and fit for purpose. Both food and drug products must be tested against established specifications to verify quality and safety, and laboratory operations must have the appropriate processes and procedures to support and defend testing results.

ISO/IEC 17025, General Requirements for the Competence of Testing and Calibration Laboratories is used to develop and implement laboratory management systems. Originally known as ISO/IEC Guide 25, first released in 1978, ISO/IEC 17025 was created with the belief that “third party certification systems [for laboratories] should, to the extent possible, be based on internationally agreed standards and procedures”7. National accreditation bodies are responsible for accrediting laboratories to ISO/IEC 17025. Accreditation bodies are responsible for assessing the quality system and technical aspects of a laboratory’s Quality Management System (QMS) to determine compliance to the requirements of ISO/IEC 17025. ISO/IEC 17025 accreditation is pursued by many laboratories as a way to set them apart from competitors. In some cannabis markets accreditation to the standard is mandatory.

The approach to ISO/IEC 17025 accreditation is typically summarizing the standard requirements through the use of a checklist. Documentation is requested and reviewed to determine if what is provided satisfies the item listed on the checklist, which correlate directly to the requirements of the standard. ISO/IEC 17025 covers the requirements for both testing and calibration laboratories. Due to the wide range of testing laboratories, the standard cannot and should not be overly specific on how a laboratory would meet defined requirements. The objective of any laboratory seeking accreditation is to demonstrate they have an established QMS. Equally as critical, for product testing laboratories in particular, is the objective to establish GxP, “good practices”, to ensure test methods and laboratory operations verify product safety and quality. ISO/IEC 17025 provides the baseline, but compliance to Good Laboratory Practice (GLP), Good Manufacturing Practice (GMP) and even Good Safety Practices (GSP) are essential for cannabis testing laboratories to be successful and demonstrate testing data is reliable and accurate.

Where ISO/IEC 17025 accreditation falls short

Adherence to ISO/IEC 17025, and subsequently receiving accreditation, is an excellent way to ensure laboratories have put forth the effort to establish a QMS. However, for product testing laboratories specifically there are a number of “gaps” within the standard and the accreditation process. Below are my “Top Five” that I believe have the greatest impact on a cannabis testing laboratory’s ability to maintain compliance and consistency, verify data integrity and robust testing methods, and ensure the safety of laboratory personnel.

Standard Operating Procedures (SOPs)

The understanding of what qualifies as a Standard Operating Procedure (SOP) is often misunderstood by cannabis operators. An SOP is a stand-alone set of step-by-step instructions which allow workers to consistently carry out routine operations, and documented training on SOPs confirms an employee’s comprehension of their job tasks. Although not required per the current version of the standard, many laboratories develop a Quality Manual (QM). A QM defines an organization’s Quality Policy, Quality Objectives, QMS, and the procedures which support the QMS. It is not an uncommon practice for cannabis laboratories to use the QM as the repository for their “procedures”. The intent of a QM is to be a high-level operations policy document. The QM is NOT a step-by-step procedure, or at least it shouldn’t be.

Test Method Transfer (TMT)

Some cannabis laboratories develop their own test methods, but a common practice in many cannabis laboratories is to purchase equipment from vendors that provide “validated” test methods. Laboratories purchase equipment, install equipment with pre-loaded methods and jump in to testing products. There is no formal verification (what is known as a Test Method Transfer (TMT)) by the laboratory to demonstrate the method validated by the vendor on the vendor’s equipment, with the vendor’s technicians, using the vendor’s standards and reagents, performs the same and generates “valid” results when the method is run on their own equipment, with their own technician(s), and using their own standards and reagents. When discrepancies or variances in results are identified (most likely the result of an inadequate TMT), changes to test methods may be made with no justification or data to support the change, and the subsequent method becomes the “validated” method used for final release testing. The standard requires the laboratory to utilize “validated” methods. Most laboratories can easily provide documentation to meet that requirement. However, there is no verification that the process of either validating in house methods or transferring methods from a vendor were developed using any standard guidance on test method validation to confirm the methods are accurate, precise, robust and repeatable. Subsequently, there is no requirement to define, document, and justify changes to test methods. These requirements are mentioned in ISO/IEC 17025, Step 7.2.2, Validation of Methods, but they are written as “Notes” and not as actual necessities for accreditation acceptance.

Change Control

The standard speaks to identifying “changes” in documents and authorizing changes made to software but the standard, and subsequently the accreditation criteria, is loose on the requirement of a Change Control process and procedure as part of the QMS. The laboratory is not offered any clear instruction of how to manage change control, including specific requirements for making changes to procedures and/or test methods, documented justification of those changes, and the identification of individuals authorized to approve those changes.

Out of Specification (OOS) results

The documentation and management of Out of Specification (OOS) testing results is perhaps one of the most critical liabilities witnessed for cannabis testing laboratories. The standard requires a procedure for “Nonconforming Work”. There is no mention of requiring a root cause investigation, no requirement to document actions, and most importantly there is no requirement to document a retesting plan, including justification for retesting. “Testing into compliance”, as this practice is commonly referred to, was ruled unacceptable by the FDA in the highly publicized 1993 court case United States vs. Barr Laboratories.

Laboratory Safety

FDAlogoSafe laboratory practices are not addressed at all in ISO/IEC 17025. A “Culture of Safety” (as defined by the Occupational Safety and Health Administration (OSHA)) is lacking in most cannabis laboratories. Policies and procedures should be established to define required Personal Protective Equipment (PPE), the safe handling of hazardous materials and spills, and a posted evacuation plan in the event of an emergency. Gas chromatography (GC) is a common test method utilized in an analytical testing laboratory. GC instrumentation requires the use of compressed gas which is commonly supplied in gas cylinders. Proper handling, operation and storage of gas cylinders must be defined. A Preventative Maintenance (PM) schedule should be established for eye wash stations, safety showers and fire extinguishers. Finally, Safety Data Sheets (SDSs) should be printed and maintained as reference for laboratory personnel.

ISO/IEC 17025 accreditation provides an added level of trust, respect and confidence in the eyes of regulators and consumers. However, the current process of accreditation misses the mark on the establishment of GxP, “good practices” into laboratory operations. Based on my experience, there has been some leniency given to cannabis testing laboratories seeking accreditation as they are “new” to standards implementation. In my opinion, this is doing cannabis testing laboratories a disservice and setting them up for failure on future accreditations and potential regulatory inspections. It is essential to provide cannabis testing laboratory owners and operators the proper guidance from the beginning and hold them up to the same rigor and scrutiny as other consumer product testing laboratories. Setting the precedence up front drives uniformity, compliance and standardization into an industry that desperately needs it.

First in the South – Virginia’s Legalization Focuses on Public Safety, Health and Social Justice

By Gregory S. Kaufman, Jessica R. Rodgers
No Comments

With the signing of the Cannabis Control Act (the Act) on April 21, 2021, Virginia became the first southern state to legalize adult use cannabis and just the fourth state to do so through the legislature. Legalizing adult use cannabis through the legislature, as opposed to through the ballot box, is not the typical route states have followed up to now. Eleven of the sixteen states and the District of Columbia have legalized adult use cannabis through the use of ballot measures. Virginia joins Vermont, Illinois, New York and New Mexico (which legalized after Virginia) as one of the few states that have gone the legislative route. Under Governor Northam’s administration, the path to legalization was swift, taking less than four months from introduction to passage.

Governor Northam added amendments to the already passed Senate Bill 1406 and the General Assembly voted to approve those amendments, with the Lieutenant Governor breaking the tie in the Senate’s vote. Upon signing, Governor Northam called the law a step towards “building a more equitable and just Virginia and reforming our criminal justice system to make it more fair.” This message and the opportunities to promote social equity through a legal cannabis industry have been consistent points of advocacy made by supporters as the bill advanced to becoming law.

Prior to the Governor’s amendments, the Act under consideration set July 1, 2024 as the date on which both legal possession and adult use sales would begin. The Governor decided to accelerate the date for legal possession to July 1 of this year, a decision believed to have been influenced by data showing that Black Virginians were more than three times as likely to be cited for possession, even after simple possession was decriminalized in the state a year prior. The regulated adult use market is still set to begin making sales on July 1, 2024; however, it remains possible that this date could be advanced through the legislature in the meantime. Nevertheless, Virginia is on track to becoming the first southern state with an operating regulated commercial cannabis market.

Creating an Administrative Structure for the Adult Use Program

Virginia became the first state in the South to legalize adult use cannabis

This sweeping fifty-page law creates the Cannabis Control Authority to regulate the cultivation, manufacture, wholesale and retail sale of cannabis and cannabis product. The Act further lays the groundwork for licensing market participants and regulating appropriate use of cannabis; defining local control; testing, labeling, packaging and advertising of cannabis and cannabis products; and taxation. The Act also contains changes to the criminal laws of the Commonwealth. Companion to the Act are new laws addressing the testing, labeling and packaging of smokable hemp products and manufacturing of edible cannabis products. Additionally, the Cannabis Equity Reinvestment Board was created to address the impact of economic divestment, violence and criminal justice responses to community and individual needs through scholarships and grants.

While persons 21 years or older may possess up to one ounce of cannabis and cultivate up to four plants for personal use per household beginning on July 1, 2021, there are a host of regulations to be written in order to regulate the adult use market. These regulations will be the devil in the details of how the regulated market will work. Regardless, the Cannabis Control Act does establish the framework for adult use cannabis that is unique to Virginia and designed to promote and encourage participation from people and communities disproportionately impacted by cannabis prohibition and enforcement.

The Cannabis Control Authority (CCA) will consist of a Board of Directors, the Cannabis Public Health Advisory Council, the Chief Executive Officer and employees. The Board will have five members appointed by the Governor and confirmed by the legislature, each with the possibility of serving two consecutive five-year terms. The Board is tasked with creating and enforcing regulations under which retail cannabis and cannabis products are possessed, sold, transported, distributed, and delivered. It is expected that the Board will begin discussing regulations next year and that applications for licenses for cannabis cultivation facilities, manufacturing facilities, cannabis testing facilities, wholesalers, and retail stores will begin to be accepted in 2023. Importantly, a Business Equity and Diversity Support Team, led by a Social Equity Liaison, and the Equity Reinvestment Board, led by the Director of Diversity, Equity and Inclusion, are to contribute to a plan to promote and encourage participation in the industry by people from disproportionately impacted communities.

Regulating Participation in the Market

The Act empowers the Board to establish a robust and diverse marketplace with many entry opportunities for market participants. Up to 450 cultivation licenses, 60 manufacturing licenses for the production of retail cannabis products, 25 wholesaler licenses and 400 licenses for retail stores can be granted. These numbers do not include the four permits granted to pharmaceutical processors (entities that cultivate and dispense medical cannabis) under the Commonwealth’s medical program.

In addition to the sheer number of licenses that can be granted, the Act devises a unique approach to addressing concerns of a concentration of licenses in too few hands and a market dominated by large multi-state operators. At the same time, it sets up a mechanism to capitalize two cannabis equity funds intended to benefit persons, families and communities historically and disproportionately targeted and affected by drug enforcement through grants, scholarships and loans. Over-concentration and market dominance concerns are addressed by limiting a person to holding an equity interest in no more than one cultivation, manufacturing, wholesaler, retail or testing facility license. This eliminates the ability of companies to be vertically integrated from cultivation through retail sales operations. However, there are two exceptions to the impediment to vertical integration. First, the Board is authorized to develop regulations that permit small businesses to be vertically integrated and ensure that all licensees have an equal and meaningful opportunity to participate in the market. These regulations will be closely scrutinized by those looking to enter Virginia’s regulated market once they are proposed. Qualifying small businesses could benefit substantially from the economic advantages commensurate with being vertically integrated, assuming they have the access to the capital needed to achieve integration and operate successfully. The second exception allows permitted pharmaceutical processors and registered industrial hemp processors to hold multiple licenses if they pay $1 million to the Board (to be allocated to job training, the equity loan fund or equity reinvestment fund) and submit a diversity, equity and inclusion plan for approval and implementation. Consequently, Virginia is attempting to fund, in part, its ambitious social equity programs by monetizing the opportunity for these processors to participate vertically in the adult use market.

Those devilish details of how this market will function, and how onerous compliance obligations will be, will emanate from those yet to be proposed regulations covering many areas and subject matters including:

  • Outdoor cultivation by cultivation facilities;
  • Security requirements;
  • Sanitary standards;
  • A testing program;
  • An application process;
  • Packaging and labeling requirements;
  • Maximum THC level for retail products (not to exceed 5 mg per serving or 50 mg per package for edible products);
  • Record retention requirements;
  • Criteria for evaluating social equity license applications based on certain ownership standards;
  • Licensing preferences for qualified social equity applicants;
  • Low interest loan program standards;
  • Personal cultivation guidelines; and
  • Outdoor advertising restrictions.

Needless to say, the CCA Board has a lot work ahead in order to issue reasonable regulations that will carry out the dictates in the Act and encourage the development of a well-functioning marketplace delivering meaningful social equity opportunities.

Much work needs to be done before July 1, 2024 to prepare for its debutThe application process for the five categories of licenses will be developed by the Board, along with application fee and annual license fee amounts. It is not clear how substantial these fees will be and what effect they will have on the ability of less-well-capitalized companies and individuals to compete in the market. The Act dictates that licenses are deemed nontransferable from person to person or location to location. However, it is not entirely clear that changes in ownership will be prohibited. The Act contemplates that changes in ownership will be permitted, at least as to retail store licensees, through a reapplication process. Perhaps the forthcoming regulations will add clarity to the transferability of licenses and address the use of management services agreements as a potential workaround to the limitations in license ownership.

Certain requirements particular to certain license-types are worthy of highlighting. For example, there are two classes of cultivation licenses. Class A cultivation licenses authorize cultivation of a certain number of plants within a certain number of square feet to be determined by the Board. Interestingly, Class B licenses are for cultivation of low total THC (no more than 1%) cannabis. Several requirements specific to retail stores are noteworthy. Stores cannot exceed 1,500 square feet, or make sales through drive-through windows, internet-based sales platforms or delivery services. Prohibitive local ordinances are not allowed; however, localities can petition for a referendum on the question of whether retail stores should be prohibited in their locality. Retail stores are allowed to sell immature plants and seek to support the home growers, an allowance that is fairly unique among the existing legal adult-use states.

Taxing Cannabis Sales

Given the perception that regulated cannabis markets add to state coffers, it is little surprise that Virginia’s retail market will be subject to significant taxes. The taxing system is straightforward and not complicated by a taxing regime related to product weight or THC content, for example. There is a 21% tax on retail sales by stores, in addition to the current sales tax rates. In addition, localities may, by ordinance, impose a 3% tax on retail sales. These taxes could result in a retail tax of approximately 30%.

Changes to Criminal Laws

Changes to the criminality of cannabis will have long lasting effects for many Virginians. These changes include:

  • Fines of no more than $25 and participation in substance abuse or education programs for illegal purchases by juveniles or persons 18 years or older;
  • Prohibition of warrantless searches based solely on the odor of cannabis;
  • Automatic expungement of records for certain former cannabis offenses;
  • Prohibition of “gifting” cannabis in exchange for nominal purchases of some other product;
  • Prohibition of consuming cannabis or cannabis products in public; and
  • Prohibition of consumption by drivers or passengers in a motor vehicle being driven, with consumption being presumed if cannabis in the passenger compartment is not in the original sealed manufacturer’s container.

These changes, and others, represent a balancing of public safety with lessons learned from the effects of the war on drugs.

Potpourri

The Act contains myriad other noteworthy provisions. For example, the Board must develop, implement and maintain a seed-to-sale tracking system for the industry. Plants being grown at home must be tagged with the grower’s name and driver’s license or state ID number. Licenses may be stripped from businesses that do not remain neutral while workers attempt to unionize. However, this provision will not become effective unless approved again by the legislature next year. Banks and credit unions are protected under state law for providing financial services to licensed businesses or for investing any income derived from the providing of such services. This provision is intended to address the lack of access to banking for cannabis businesses due to the federal illegality of cannabis by removing any perceived state law barriers for banks and credit unions to do business with licensed cannabis companies.

The adult use cannabis industry is coming to Virginia. Much work needs to be done before July 1, 2024 to prepare for its debut. However, the criminal justice reforms and commitment to repairing harms related to past prohibition of cannabis are soon to be a present-day reality. Virginia is the first Southern state to take the path towards legal adult use cannabis. It is unlikely to be the last.

Americans for Safe Access Accredited to ISO 17065

By Cannabis Industry Journal Staff

Late last week, the American Association for Laboratory Accreditation (A2LA) granted ISO/IEC 17065 accreditation to Americans for Safe Access (ASA). This is the first accreditation ever issued to a product certification body in the cannabis market.

ASA is a member-based organization founded in 2002 that seeks to ensure safe and legal access to cannabis for medical purposes and research. Back in 2016, A2LA and ASA partnered on a collaboration to develop the Patient Focused Certification (PFC) program.

What started as a supplement to ISO 17025 for cannabis testing labs to demonstrate a dedication to patient safety, has grown into a more comprehensive certification and consulting program that offers training, business services, company certifications. With the ISO 17065 accreditation, ASA can now deliver PFC certifications that confidently identify reliable and high-quality medical cannabis products, business and services.

Jonathan Fuhrman, program manager at A2LA, says this is a big milestone for ASA’s platform. “ISO/IEC 17065 and product certification can play a decisive role in the evolution of cannabis as medicine,” says Fuhrman. “With its high standards for competence and impartiality, adopting ISO/IEC 17065 represents a major win for healthcare providers and patients.”

Heather Despres, the director of ASA’s Patient Focused Certification program, says she is thrilled to be the first cannabis compliance organization to attain the accreditation. “The PFC program was developed by ASA in an effort to continue our commitment to protect patients, many of whom are medically fragile, and consumers who may be seeking medicine outside of conventional medicinal channels,” says Despres. “There is no other process that can demonstrate that continued commitment more than achieving ISO 17065 accreditation.”

Leaders in Cannabis Formulations: Part 2

By Aaron Green

Editor’s Note: In Part 1 of this series, green sat down with Drew Hathaway, senior food scientist at Stillwater Brands. Click here to see Part 1.

Natural cannabinoid distillates and isolates are hydrophobic oils and solids, meaning that they do not mix well with water and are poorly absorbed in the human body after consumption. By formulating these ingredients using a patented delivery system technology, trademarked VESIsorb®, Geocann has overcome common obstacles associated with fat-soluble active ingredients, including poor stability, bioavailability, absorption, and solubility. In addition, Geocann has peer-reviewed, published evidence of the dramatic improvements in Cmax, AUC, and Tmax (“time to peak absorption” directly related to “fast-acting” benefits).

Geocann is a cannabis formulation company with its headquarters in Fort Collins, Colorado, and additional offices in Chicago, Illinois and Zurich, Switzerland. The company is led by an impressive leadership team of scientists, pharmacists, researchers and natural product industry leaders. Geocann’s technology platform has been successfully applied to a wide range of cannabis product applications, including soft gel and hard-shell capsules, functional foods (e.g. gummies) and beverages, powder systems, tinctures, sublingual sprays and topically applied formulations. Brand partners in the U.S. utilizing Geocann’s technology for hemp applications include Nestlé Health Science, Cannaray and Onnit, and brand partners for medical and adult-use cannabis applications include Curaleaf, Sunderstorm and CannaCraft, among others.

We spoke with Jesse Lopez, CEO and Founder of Geocann, about their product formulation technology in cannabis and how they work with brand partners in the U.S and internationally. Lopez started Geocann in 2018 alongside the success he’s experienced at SourceOne Global Partners (founded in 2003 by Lopez), a leading formulation company in the nutraceuticals space with a reputation for pioneering innovative products that combine science-backed ingredients with patented drug delivery system technologies to address the most pressing consumer health concerns, such as heart health, cognitive function, inflammatory response, metabolic syndrome and type II diabetes, among others.

Aaron Green: Jesse, first off, how did you get involved in the cannabis industry?

Jesse Lopez: Our focus at SourceOne Global Partners has been on natural products for nearly two decades. Some of the folks involved with our natural products business decided that they would get involved in the cannabis business and they asked for my support at the Advisory Board level. I agreed to serve and figured I better learn about the cannabis industry! We realized that there was a tremendous opportunity for utilizing our drug delivery system technology to enhance the value of these cannabis-based products. Due to the regulatory environment, strategic legal counsel and new investments necessary to take an immediate leadership position in the cannabis industry we launched Geocann in 2018 with an office in a fully legal state at the time, Colorado.

Green: How do you select the natural products you work with at SourceOne?

Jesse Lopez, CEO and Founder of Geocann

Lopez: We really focus on science-backed natural product ingredients that may require high doses to reach therapeutic blood levels. By combining these science-backed ingredients with patented technologies – which we own the global rights to – these products offer desirable differentiation for leading brands, such as dramatically improved absorption and bioavailability, patent protection and trademarked “intel inside” branding.

Green: What are some of the other natural products you have experience with?

Lopez: We work with a range of some of the most popular nutraceuticals such as coenzyme Q10 and omega-3 fish oil to the more innovative natural products like resveratrol. We also work with vitamin D, and other immunity-based ingredients that can be enhanced using our delivery system technology to deliver greater benefits to the people that are taking those products.

Green: What is the technology and how does it work?

Lopez: I think it’s important to recognize our technology partner, Vesifact, in Zurich, Switzerland, who is the inventor of the VESIsorb® technology platform and serves as the scientific research, technical support, production, and product development arm of SourceOne and Geocann. We are very proud of this symbiotic relationship where our role at Geocann and SourceOne is to provide the commercial development, sales, marketing and strategic distribution infrastructure. We promote our partnership openly on our website and in our marketing materials because of their unrivaled leadership position in the global marketplace.

They have consistently been recognized as a top 10 global organization for health-related nanotechnology patent activity, ahead of many of the most well-known pharmaceutical companies in the world. It is an intellectual property portfolio that has been used to provide solutions to the most difficult product formulation challenges over the years in pharmaceuticals, medical devices, nutraceuticals, cosmetics, and now cannabis applications. Together, our focus has been on delivering novel solutions in these diverse fields of use and product applications based upon VESIsorb® formulation technology.

Each active compound identified with its own set of formulation, absorption and bioavailability challenges requires a customized solution that allows the full potential health benefits to be realized from success in the lab to commercial scale up. This is the process and we have successfully delivered unmatched solutions for close to twenty years from coenzyme Q10 to now both psychoactive and non-psychoactive cannabinoid product formulations in a wide range of product applications.

We saw the exploding interest in CBD with our nutraceutical partners and demanding consumers worldwide but chose to start Geocann to keep the markets served separate. We were confident that the VESIsorb® technology would provide much needed solutions for CBD as a wellness product, but also adult-use and medical cannabis products regarding “fast acting” and “product stability” needs.

Green: What’s the problem in cannabinoid bioavailability that Geocann’s technology helps to solve?

Lopez: It is well-recognized in the scientific literature that CBD, THC and other cannabinoids, in general, show limited bioavailability due to their lipophilicity, poor aqueous solubility and extensive first-pass metabolism.

Our VESIsorb® technology was designed to address the poor bioavailability of drugs and natural bioactives like cannabinoids exhibiting poor water solubility but high membrane permeability (Biopharmaceutical Classification System: Class II compounds). The VESIsorb® technology is a lipid-based formulation that self-assembles on contact with an aqueous phase into a colloidal delivery system. This colloidal solubilization improves the transport of the cannabinoids through the aqueous phase of the GI-lumen to the absorptive epithelium, dramatically improving bioavailability.

VESIsorb® is typically characterized as a SEDDS (self-emulsifying drug delivery system). What’s unique about our VESIsorb® SEDDS is the long history of safe and effective use worldwide and the large number of products that, over the years, we’ve successfully developed. With decades of experience delivering novel formulation solutions, there is significant and valuable “know how” that we bring to each formulation challenge.  This “know how” allows us, for example, to develop cannabinoid formulations that provide lymphatic absorption pathway advantages in addition to standard gastrointestinal absorption, therefore optimizing therapeutic blood levels for maximum benefits.

Needless to say, there are various methods that attempt to address the poor cannabinoid bioavailability. Unfortunately, too often, companies make claims that they have water soluble cannabinoids but offer little evidence to validate their claims. The popular misconception is that some degree of water solubility will consistently translate to improved bioavailability. This is clearly not accurate. We know scientifically that pharmacokinetic performance is highly variable. A review paper I read recently comparing water soluble delivery system formulation types illustrated this fact. There was greater than an eight-fold difference in bioavailability amongst the various water-soluble formulations.

Green: Can you tell me some details about your global license with Vesifact?

Lopez: Our technology exclusivity is based upon given categories. So, when we say we have global exclusivity for nutraceuticals, that can be as I’ve already mentioned, omega-3, coenzyme Q10, or resveratrol as examples, and this business is managed by SourceOne. With regards to our global exclusivity for cannabinoids and terpenes– whether we formulate these ingredients to create a functional drink, or we’re creating a gummy, or creating a softgel capsule or powder-filled hard-shell capsule, or sublingual, or topical – all of those product applications are covered by ourexclusivity for the technology and is managed by Geocann.

The beauty of our technology is that we’ve already achieved success with all of those product applications. That’s one of the big advantages of our technology versus some other approaches trying to address the challenges of cannabinoid bioavailability.

Green: What kind of validation and clinical studies have you done so far in the cannabinoid space?

Lopez: We were the first to have stability data with creating our formulation in a soft gel capsule with CBD. We recently submitted to the European market for novel food application. We invested hundreds of thousands of dollars in proprietary safety studies that are required to achieve novel food status in Europe and FDA GRAS in the U.S. We have proprietary stability data as well as proprietary toxicology data from multiple, self-funded clinical studies. Many companies that submit for the EU novel food application are only referencing the existing scientific literature about the pharmacokinetics of cannabinoids, whereas we have our own peer-reviewed, published study. In our study, we compared our VESIsorb®-CBD formulation to the industry standard MCT Oil-CBD formulation in a crossover design where we were able to demonstrate how we could dramatically improve the bioavailability of CBD.

Green: Can you talk about the benefits of your technology with regards to bioavailability and onset time?

Lopez: When you start talking about onset time we move into a broader discussion relative to cannabinoids. We’ve been very successful with marijuana, especially as it relates to THC, because of the dramatic improvement in time to Tmax, and how much faster we reach Tmax than a standard THC formula. Our formulation is generally four times faster compared to standard formulations.

When it comes to area under the curve and Cmax, we show improvements of four to six times a standard THC or CBD product. Further, when we start looking at the differences between other studies that have been published, we show an even greater improvement based upon study comparisons to what other people have done, even compared to products like GW Pharmaceuticals’ Sativex Oromucosal Spray.

Green: Can you address the SEDDS formulation and liver metabolism?

Lopez: We’ve dramatically overcome challenges with the first-pass effect. We have also formulated our products to address lymphatic absorption. So, we’re coming at it from a number of different angles.

We disagree with people who talk about water solubility as an end-all be-all solution. When you look at the range of published studies, whether it’s nanoparticles or liposomal systems or micro-emulsions, they all are water soluble systems, but yet the data shows there’s dramatic differences in the real efficacy of those approaches, and what the actual improvement in blood levels are. Ultimately, those blood levels represent the efficacious nature of the products whether we’re talking about CBD, or talking about THC.

Green: As a Colorado-based company you work with cannabis partners across the US. Can you tell me about your relationship with marijuana product formulators and brands and how you structure your licensing agreements across state boundaries?

Lopez: In a recent article about the leading fast acting gummies, the two companies they focused on were Sunderstorm with the Kanha Nano gummies and Curaleaf with their Select Fast Acting Nano gummies. Both of those companies use our VESIsorb® technology. We’re very proud of our relationship and the success they’re having as leaders in most dominant states with that particular product application.

Onset time has always been a challenge with gummies. And we’ve dramatically improved onset. Actually, we’ve shown statistically significant improvements for all measured pharmacokinetic parameters in a recent peer-reviewed published study.  We demonstrated much higher total absorption in maximum plasma concentration (Cmax), total exposure [area under the curve (AUC)]) and the time to reach the peak concentration (Tmax).

We say powered by VESIsorb® technology the product is faster, stronger, longer.

Green: How does the experience differ from a standard oil- or isolate-based formulation?

Lopez: The only way that I can answer that question is we’ve had 100% success with the companies we work with in their initial trials. When someone tells me that a group of employees are going to try the product and they’re heavy users of cannabis and they are smokers, I think, “wow, you know, gummies have to be really successfully formulated for someone like that to be pleased with the high.” Then they come back and say, “that’s the best that I’ve had in four years!” and they’re totally blown away. That’s completely different than a peer reviewed published study, but for sure, that’s the kind of feedback and anecdotal evidence that we get. I think that’s why that application is growing so much faster now because we’ve overcome this onset issue.

Green: Do you give exclusive rights on a state-by-state basis?

Lopez: We’re very selective about who we work with. Exclusivity is always part of the discussion. But at the same time, it’s really more about protecting the investment in the people that we partner with and not cannibalizing a given market. So, there are some exclusive relationships in the U.S. and internationally, like Heritage Cannabis and Pathway Health Corp in Canada, but for the most part, I would say simply, we were very selective about who we do business with and open to new partnerships.

Green: What kind of support do you provide to your licensing partners?

Lopez: We provide 100% formulation and technical support. We provide the SEDDS and then they use their own legal, licensed cannabis and their own equipment. Our system requires no special equipment or investment in changes to their process. So, not only do we provide formulation expertise, but our system is really easy to use both in a lab environment as well as producing large scale commercial productions.

Green: What geographies are you in currently with the cannabinoid formulations?

Lopez: We are global in scope. We’ve been very fortunate to have success not only in the US and Canada, but Europe, Brazil and Australia as well. Our level of participation will vary whether we’re talking about medical marijuana, adult-use or hemp extract and CBD.

Green: If somebody is interested in learning more about your product or potentially becoming a license partner, how would they how would they reach out to you to set that up?

Lopez: If they went to our website, www.geocann.com, it’s pretty easy to reach us and I am grateful that so many companies are doing that.

Green: Great, thanks Jesse that concludes the interview!

How to Develop Quality Cannabis Products with Advanced Analytical Testing

By Vanessa Clarke, Melody Lin
No Comments

A thorough cannabis product development process goes far beyond extracting and packaging. Performing advanced analytical testing at each and every stage allows producers to know the quantity, quality and behaviour of compounds in samples. Here are the four key stages from flower to consumption.

Stage 1: Flower

Developing a quality cannabis product begins with knowing the composition of compounds in your starting material. The best analytical tests utilize a metabolomics approach. Metabolomics is a suite of techniques that include a variety of instruments to run samples through in order to receive compositional data. In this stage, LC-qTOF and GC-MS are the best instruments to track all the compounds in the starting plant material. Essentially, metabolomics establishes a fingerprint of the compounds in a plant sample. This is beneficial because producers have to understand how their chosen cannabis plant differs from other cultivars and how it would potentially behave in their desired end product formulations.

Stage 2: Concentrate

After the plant material has gone through an extraction process, producers want to know precisely what is in the extract. Are there compounds that should not be there and are all the desired compounds present? The best way to test the quality of cannabis oils is again to use metabolomics (e.g. via LC-qTOF). This test reveals all the compounds in the sample in order to help the producer determine the purity and consistency of molecules beyond just THC and CBD.

When testing cannabis isolates, it is best to use NMR spectroscopy and X-ray diffraction. NMR characterizes and assesses the purity of single compounds or mixtures in solution or solid state. X-ray diffraction provides information about the crystal structure, chemical composition and the physical properties of the cannabis sample to help the producer prove the identification of desired compounds. Establishing that the concentrates are pure and aligned with what the producer intended to extract is key in this stage of product development.

Stage 3: Formulation

Designing an appropriate drug delivery formula is a universal challenge producers face at this stage of product development. Where nanoemulsion or other carrier approaches are being used, formulation characterization allows producers to understand how their active compounds behave in simulated physiological environments as well as how stable their products are over time. Specifically, nanoparticle sizing and assessing size changes over time can help a formulation scientist ensure the highest quality product is being mixed, and that the desired effect will be imparted on the consumer/patient.

Stage 4: Smoke/Vapor

Many producers might not consider this final stage, but it is critical for all inhalable cannabis products and devices. Using a smoke analyzer and metabolomics testing can identify and quantify compounds present within the formed smoke or vapor from pre-roll joints to vape devices. This is not only important for preventing the production of toxic by-products, but it can help producers create an optimal smoking experience for consumers.

One area that is often an afterthought is quality compliance testing. Despite a number of groups using the required tests well during development, many forget to continue the same robust testing on end products. In the current cannabis product development landscape, there is little guidance on how compliance testing should be conducted on every product “batch.” With these advanced analytical tests, producers can confidently develop compliant, stable and quality cannabis products.

 

Navigating Compliance: Practical Application of Fit-For-Purpose

By Darwin Millard
No Comments

What is “fit-for-purpose?” Fit-for-purpose is an established best practice used in several major industries, like information technology, pharmaceuticals, agriculture and inventory management. It is a concept that aligns infrastructure and systems specifications with desired outputs – be that product, service or bottom line. When applied to a cannabis plant, its parts, products and associated processes, it can streamline regulatory framework development, implementation and compliance.

Fit-for-purpose is simply a series of logic questions you ask yourself to determine what business practices you should implement and the regulatory framework in which you must comply. What are you making? Who is it for? Where will it be sold? All this impacts how you would cultivate, process, handle and store a cannabis plant, its parts and products regardless of the type of cannabis plant. The fit-for-purpose concept is a tool that can be applied to any scenario within the cannabis/hemp marketplace. Take for instance, sustainability: a practical example would be to design cultivation standards that are “fit-for-purpose” to the climatic region in which the plants are grown – allowing any type of cannabis plant grown anywhere in the world to meet specifications regardless of the method of production.

There is no “special sauce” here. All fit-for-purpose does is get you to ask yourself: “Are the protocols I am considering implementing ‘fit/appropriate’ to my situation, and if not, which protocols are more ‘fit/appropriate’ based on the products I am making, the target consumer and marketplace in which the products are to be sold?”“Fit-for-purpose is a powerful concept that can be used for simplifying regulatory framework development, implementation and compliance”

A non-cannabis/hemp example of fit-for-purpose could be a scenario where a banana producer wants to implement a data management system into their cultivation practices to better track production and yields. There are many data management systems this banana producer could implement. They could implement a data management system like that of big pharma with multiple levels of redundancy and access control related to intellectual property and other sensitive data. They could also implement a data management system used for tracking warehouse inventory; it cannot exactly capture everything they need but it is better than nothing. Neither example is really “fit/appropriate” to the banana producer’s needs. They need something in between, something that allows them to track the type of products they produce and the data they want to see in a way that is right for them. This idea is at the core of the fit-for-purpose concept.

Applying Fit-for-Purpose

So how do we apply fit-for-purpose to the cannabis/hemp marketplace? Fit-for-purpose reduces the conversation down to two questions: What products are you planning to make and how do those products affect your business practices, whether that be cultivation, processing, manufacturing or compliance. The point being the products you plan to produce determine the regulations you need to follow and the standards you need to implement.

Growers can use it to guide cultivation, harvesting, handling and storage practices. Processors and product manufacturers can use it to guide their production, handling, packing and holding practices. Lawmakers can use it to guide the development, implementation and enforcement of commonsense regulations. This is the beauty and simplicity of fit-for-purpose, it can be applied to any situation and related to any type of product.

Growers can use fit-for-purpose to guide most aspects of their operation

Let us look at some practical examples of fit-for-purpose for cultivators and processors. Cultivators have three main areas of focus, growing, harvesting and storage, whereas processors and product manufacturers have it a little more complicated.

Cultivation of a Cannabis Plant

Growing

Requirements for growing a cannabis plant, including those that can be classified as “hemp”, should be dictated by the product with the strictest quality and safety specifications. For example, growing for smokable fruiting tops (i.e. the flowers) may require different cultivation techniques than other products. You may not want to apply the same pesticides or growth additives to a cannabis plant grown for smokable fruiting tops as you would to a cannabis plant grown for seed and fiber.

Harvesting

The next point is important – harvesting and handling requirements should be agricultural, period. Except for those products intended to be combusted or vaporized and then inhaled. Following our previous example, smokable fruiting tops may require different harvesting techniques than other products, especially if you are trying to maintain the aesthetic quality of these goods. You may choose a different harvesting technique to collect these fruiting tops than you would if primarily harvesting the seed and fiber and thinking of the leftover biomass as secondary.

Storage

When considering the products and their storage, you need to consider each one’s quality and safety specifications. One product may have a temperature specification, whereas another may have a humidity specification. You need to make sure that you store each product according to their individual quality and safety specifications. Then consider the products with the highest risks of diversion and potentially if you need to implement any extra protocols. Continuing our example – smokable fruiting tops, whether classifiable as “hemp” or not, pose a higher risk of theft than seeds or fiber and may require additional security measures depending on the authority having jurisdiction.

Processing and Manufacturing Operations

When applying fit-for-purpose to processing and manufacturing operations, first you must choose the products you want to make and specify the intended use for each product. This allows you to identify the quality and safety requirements and the potential for diversion for each good. Which in turn allows you to specify your manufacturing, processing and handling protocols for each product related to their quality and safety requirements. Then those specific products with higher risks of diversion requiring extra protocols to be put into place depending on local regulations and/or internal risk assessments, should be considered and your practices modified, as necessary.

Commonsense Regulations

Image if regulations governing a cannabis plant, its parts, products and associated processes were based on the intended use rather than a set of attributes that vary from jurisdiction to jurisdiction. It is complicated enough for regulators to think about a cannabis plant or cannabis product without having to worry about if that cannabis plant or cannabis product can be classified as “marijuana” or “hemp.” Fit-for-purpose removes this complication and simplifies the debate.

Using a fit-for-purpose approach eliminates the need to think about the molecular constituents and focuses the conversation on the intended use rather than one or two specific molecules – in this case, d9-THC, the boogie-man cannabinoid. Considering the intended use promotes consumer and environmental health and safety by allowing operators and regulators to focus on what is most important – quality and safety instead of whether something is “marijuana” or “hemp.”

This idea is what drives the real impact of fit-for-purpose. It creates a path forward to a one plant solution. We have where we are now – with “marijuana” and “hemp” – and where we want to get to – cannabis. It is all one plant with many different applications that can be used to create different commercial products. Fit-for-purpose helps bridge the gap between where we are now and where we want to get to and allows us to start thinking about “marijuana” and “hemp” in the same manner – the intended use.

Fit-for-purpose is a powerful concept that can be used for simplifying regulatory framework development, implementation and compliance. Regulations imposed on a cannabis plant, its parts and products should be appropriate to their intended use, i.e. “fit-for-purpose.” This approach challenges the confines of the current draconian bifurcation of the cannabis plant while working within this system to push the boundaries. It creates a path forward to a one plant solution and begs the question: Is the world ready for this novel concept?

GMPs & Cannabis Manufacturing

By Kathleen May

Editor’s Note: While CIJ typically omits the word “marijuana” where possible due to antiquated nomenclature and prejudicial connotations, we understand the legal distinction between cannabis containing THC and hemp requires the use of the word when referencing federal government policies and legislative language.

Despite the rapid evolution of the cannabis industry, the assurance of safe manufacturing practices remains unclear.Both the Food and Drug Administration (FDA) and the Drug Enforcement Administration (DEA) have imposed significant hurdles for cannabis operators to remain on the “right side of the law.” Therefore, manufacturers of both hemp and marijuana products have been left to figure things out on their own, or choose to ignore existing guidance because the lack of federal oversight allows them to do so. Inconsistent regulation on manufacturing, packaging, labeling and testing of cannabis products offers the potential for unsubstantiated, non-scientific and often times blatantly false claims on product safety and efficacy.

Science vs. Law

Hemp and marijuana are both species of the Cannabis family, Cannabaceae. Genetically they are identical but are arbitrarily defined by the presence of delta-9 tetrahydrocannabinol (THC). While science does not differentiate between hemp and marijuana, the law does.

The hemp industry declared a small victory with the passing of the Agricultural Act of 2014 (2014 Farm Bill). Under this bill universities and state agriculture departments were allowed to grow hemp under state law. Additionally, “industrial hemp” was officially defined by establishing the legal limit of THC at 0.3% on a dry weight basis. The Agricultural Improvement Act of 2018 (2018 Farm Bill), under the guidance of the United States Department of Agriculture (USDA), took things a few steps further by authorizing the cultivation of hemp and removed hemp and hemp seeds from the CSA. The bill however provides no language that mandates the safe manufacture of hemp-derived consumer goods. The 2018 version also preserved the FDA’s authority to regulate products containing cannabis and cannabis-derived compounds under the Federal Food, Drug, and Cosmetic Act (FD&C Act). To the surprise of most, listing cannabidiol (CBD), even hemp-derived, as an ingredient on consumer product labels remains illegal under the bill. Furthermore, CBD product manufacturers are not protected under the current regulations. Since 2015 the FDA has issued warning letters to firms marketing CBD products as dietary supplements and/or foods, and in December 2018, FDA declared it illegal to introduce food containing CBD (or THC) into interstate commerce, regardless if it is derived from hemp. To date, the only FDA approved CBD product is GW Pharmaceutical’s Epidiolex.

Marijuana remains classified as a Schedule I controlled substance under the CSA. Thirty-six (36) states have approved comprehensive, publicly available medical marijuana programs, and now 14 states have approved adult use programs, with New Jersey passing legislation on February 22, 2021. However, the industry has seen minimal movement toward mandating GMP requirements in the marijuana market. Only a handful of medical programs require manufacturers to follow GMP. Furthermore, the requirements are inconsistent between states and the language in the regulations on how to approach GMP implementation is vague and disjointed. This fragmented guidance supports the complexity and difficulty of enforcing a coherent, standardized and reliable approach to safe manufacturing practices.

What is GMP and Why Should You Care?

Good Manufacturing Practices (GMPs) are a system for ensuring that products are consistently manufactured and controlled according to quality standards and regulatory guidelines. The implementation of a GMP compliant program ensures consumer health and safety, allows manufacturers to understand the intended use of their products, allows manufacturers to defend product specifications as being appropriate, considers the risks to vulnerable populations and minimizes overall business risk. In a nutshell, GMP equals product safety and quality, and defines the responsibilities of the manufacturer to ensure consumers are protected from the distribution of unsafe and ineffective products. Currently, the GMP “landscape” in the cannabis space is complicated. The various “flavors” (food, dietary supplements, cosmetics and drugs/devices) of GMP leave many confused and frustrated when making the decision to implement GMP. Confusion is a result of unclear regulatory requirements as well as operators not fully understanding how to classify or designate the end use of their product(s). Implementing an effective GMP program requires proper planning (both short and long term), financial commitment and qualified resources.

Where Should You Start?

As the regulatory landscape continues to evolve and mature in the cannabis space, your business model must consider GMP implementation if you wish to remain successful and sustainable.

Intended Use

Before you can implement GMP you must first understand what GMP regulations apply to the intended use of your product(s). Are you manufacturing food, beverages or dietary supplements? Get acquainted with the FDA Code of Federal Regulations (CFRs) on GMP. 

Conduct a Gap Assessment

A gap assessment allows you to determine your deficiencies in relation to GMP compliance. The assessment should include, but is not limited to facility design, equipment design, supply chain, risk management and employee training.

Develop an Action Plan

Once the gap assessment is complete a comprehensive action plan will be developed to map out the steps required to achieve GMP compliance. The action plan should follow the SMART Goal principles:

  • Specific (simple, well-defined)
  • Measurable (meaningful)
  • Attainable (achievable, agreed upon)
  • Relevant (resource-based, reasonable and realistic)
  • Timely (time-based, defined due dates)

The plan will include prioritized deliverables, due dates and allocated resources in order to strategically plan and execute and complete the required tasks.

Schedule a Mock GMP Inspection

A mock inspection verifies that the action plan was adequately executed. Hire an experienced resource familiar with related GMPs and QMS to conduct the inspection. A successful mock inspection is a perfect litmus test if the end goal is to achieve GMP certification.

Cannabis manufacturers that ignore the obvious progression toward an FDA-like industry will not survive the long game. Those that embrace the momentum and properly plan to mitigate product and business risk – those who demonstrate integrity and are truly in this space to ensure safe, effective and quality products to consumers will come out on top, gain credibility and secure brand recognition.

New Jersey Legalizes Adult Use Cannabis

No Comments

On February 22, 2021, New Jersey Governor Phil Murphy signed three bills into law, all of which legalize adult use cannabis in the state. A21 is the New Jersey Cannabis Regulatory, Enforcement Assistance, and Marketplace Modernization Act. A1897 is the accompanying decriminalization legislation and A5342 addresses discrepancies between the bills referencing underage possession.

Back in November 2020, voters in New Jersey overwhelmingly approved Question 1 by a 66% to 33% margin. That ballot measure made it to voters by way of the legislature, after New jersey lawmakers failed to pass a legalization bill in 2019. The legislation that Governor Murphy signed yesterday essentially put the will of the voters into law.

The legislation becomes effective immediately upon the Governor signing the bills, but New Jersey residents won’t see legal adult use cannabis until June 2021, the deadline for the five-member Cannabis Regulatory Commission to establish detailed regulations. Possession of cannabis will also not be legal until sales are underway.

The license application window will open 30 days prior to the regulatory deadline. The legislation provides for licenses in cultivation, manufacturing, wholesale, distribution, retail, delivery and testing labs. Until 2023, cultivator licenses will be capped at 37. 25% of all of the licenses are earmarked for microbusinesses that are owned locally and have less than ten employees.

According to New Jersey-based cannabis lawyer Jennifer Cabrera of Vicente Sederberg LLP, the bills include a number of provisions aimed at promoting social equity in the cannabis industry and repairing damage caused by prohibition. The language mandates that 30% of licenses must go to businesses owned by women, minorities or disabled veterans. At least 25% should be allocated to residents of impact zones, which are municipalities that have more than 120,000 residents that: rank in the top 40% of municipalities in the state for cannabis-related arrests; have a crime index of 825 or higher; and have a local average annual unemployment rate that ranks in the top 15% of municipalities.

The Capitol in Trenton, New Jersey

Advocates across the state are applauding the government’s work to include social equity provisions in the bills. States like Illinois and Massachusetts initially received a lot of praise for including a number of social equity provisions in their legalization plans, but the rollout has left a lot to be desired. Social equity applicants in Illinois are still waiting on licensing as lawsuits play out in court following allegations of corruption and ineffective distribution.

However, it looks like New Jersey is taking a much more thorough approach to social equity issues than other states. “New Jersey has adopted some of the strongest social equity provisions we’ve seen,” says Cabrera. “Contemplating these issues at the outset of the process will likely prove to be a big advantage for the state. It is much easier to build these considerations into the system than it is to go back and incorporate them later.” In other words, there is still a lot of work to be done to ensure an equitable regulatory framework is established.

Amol Sinha, executive director of the American Civil Liberties Union (ACLU) of New Jersey says the state’s laws can set a new standard for what justice can look like. “This is a new beginning – and the culmination of years of advocacy – and we must keep in mind that it is only the start,” says Sinha. “Signing these laws puts in motion the next phase of this effort: to work relentlessly to transform the principles of legalization into greater racial and social justice in New Jersey.”

It is estimated that New Jersey’s adult use cannabis market could be worth more than a billion dollars. As the state begins their rollout and implementation, all eyes are on New York and Pennsylvania, which are both expected to legalize adult use cannabis within the next two years. Both Governor Cuomo of New York and Governor Wolf of Pennsylvania have been clamoring for adult use legalization in recent months.

Cannalytics Becomes First Accredited Cannabis Lab in Puerto Rico

THC Remediation of Hemp Extracts

By Darwin Millard
1 Comment
extraction equipment

Remediation of delta-9 tetrahydrocannabinol (d9-THC) has become a hot button issue in the United States ever since the Drug Enforcement Agency (DEA) released their changes to the definitions of marijuana, marijuana extract, and tetrahydrocannabinols exempting extracts and tetrahydrocannabinols of a cannabis plant containing 0.3% or less d9-THC on a dry weight basis from the Controlled Substances Act. That is because, as a direct consequence, all extracts and tetrahydrocannabinols of a cannabis plant containing more than 0.3% d9-THC became explicitly under the purview of the DEA, including work-in-progress “hemp extracts” that because of the extraction process are above the 0.3% d9-THC limit immediately upon creation.

The legal ramifications of these changes to the definitions on the “hemp extracts” marketplace will not be addressed. Instead, this article focuses on the amount of d9-THC that is available in the plant material prior to extraction and tracks a “hemp extract” from the point it falls out of compliance to the point it becomes compliant again and stresses the importance of accurate track-n-trace protocols at the processing facility. The model developed to support this article was intended to be academic and was designed to follow the d9-THC portion of a “hemp extract” through the lifecycle of a typical CO2-based extract from initial extraction to THC remediation. A loss to the equipment of 2% was used for each step.

Initial Extraction

For this exercise, a common processing scenario of 1000 kg of plant material at 10% cannabidiol (CBD) and 0.3% d9-THC by weight was modeled. This amount, depending on scale of operations, can be a facility’s total capacity for the day or the capacity for a single run. 1000 kg of plant material at 0.3% d9-THC has 3 kg of d9-THC that could be extracted, purified, and diverted into the marketplace. CO2 has a nominal extraction efficiency of 95%, meaning some cannabinoids are left behind in the plant material. The same can be said about the recovery of the extract from the equipment. Traces of extract will remain in the equipment and this little bit of material, if unaccounted for, can potentially open an operator up to legal consequences. Data for the initial extraction is shown in Image 1.

Image 1: Summary Data Table for Typical CO2-based Extraction of Phytocannabinoids

As soon as the initial extract is produced it is out of compliance with the 0.3% d9-THC limit to be classified as a “hemp extract”, and of the 3 kg of d9-THC available, the extract contains approx. 2.8 kg, because some of the d9-THC remains in the plant material and some is lost to the equipment.

Dewaxing via Winterization and Solvent Removal

Dewaxing a typical CO2 extract via winterization is a common process step. For this exercise, a wax content of 30% by weight was used. A process efficiency of 98% was attributed to the wax removal process and it was assumed that 100% of the loss can be accounted for in the residue recovered from the equipment rather than in the removed waxes. Data for the winterization and solvent recovery are shown in Image 2 and 3.

Image 2: Summary Data Table for Typical Winterization of a CO2 Extract
Image 3: Summary Data Table for Solvent Removal from a CO2 Extract

Two things occur during winterization and solvent removal, non-target constituents are removed from the extract and there is compounded loss from multiple pieces of process equipment. These steps increase the concentration of the d9-THC portion of the extract and produce two streams of noncompliant waste.

Decarboxylation & Devolatilization

Most cannabinoids in the plant material are in their acid form. For this exercise, 90% of the cannabinoids were considered to be acid forms. Decarboxylation is known to produce a mass difference of 87.7%, i.e. the neutral forms are 12.3% lighter than the acid forms. Heat was modeled as the primary driver and a process efficiency of 95% was used for the conversion rate during decarboxylation. To simplify the model, the remaining 5% acidic cannabinoids are presumed destroyed rather than degraded into other compounds because the portion of the cannabinoids which get destroyed versus degrade into other compounds varies from process to process.

Devolatilization is the process of removing low-molecular weight constituents from an extract to stabilize it prior to distillation. Since the molecular constituents of cannabis resin extracts vary from variety to variety and process to process, the extracts were assumed to consist of 10% volatile compounds. The model combines the decarboxylation and devolatilization steps to account for complete decarboxylation of the available acidic cannabinoids and ignores their weight contribution to the volatiles collected during devolatilization. Destroyed cannabinoids result in an amount of loss that can only be accounted for through a complete mass balance analysis. Data for decarboxylation and devolatilization are shown in Image 4.

Image 4: Summary Data Table for Decarboxylation and Devolatilization of a CO2 Extract

As the extract moves along the process train, the d9-THC concentration continues to increase. Decarboxylation further complicates traceability because there is both a known mass difference associated with the process and an unknown mass difference that must be calculated and justified.

Distillation

A two-pass distillation was modeled. On each pass a portion of the extract was removed to increase the cannabinoid concentration in the recovered material. Average data for distilled “hemp extracts” was used to ensure the model did not over- or underestimate the concentration of the cannabinoids in the distillate. The variables used to meet these data constraints were derived experimentally to match the model to the scenario described and are not indicative of an actual distillation. Data for distillation is shown in Image 5.

Image 5: Summary Data Table for Distillation of a Decarboxylated and Devolatilized Extract

After distillation, the d9-THC concentration is shown to have increased by 874% from the original concentration in the plant material. Roughly 2.2 kg of the available 3 kg of d9-THC remains in the extract, but 0.8 kg of d9-THC has either ended up in a waste stream or walking out the door.

Chromatography – THC Remediation Step 1

Chromatography was modeled to remove the d9-THC from the extract. Because there are several systems with variable efficiency rates at being able to selectively isolate the d9-THC peak from the eluent stream, the model used a 5% cut-off on the front-end and tail-end of the peak, i.e. 5% of the material before the d9-THC peak and 5% of the material after the d9-THC peak is assumed to be collected along with the d9-THC. Data for chromatography is shown in Image 6.

Image 6: Summary Data Table for d9-THC Removal using Chromatography

After chromatography, a minimum of three products are produced, compliant “hemp extract”, d9-THC extract, and noncompliant residue remaining in the equipment. The d9-THC extract modeled contains 2.1 kg of the available 3 kg in the plant material, and is 35% d9-THC by weight, an increase of 1335% from the distillation step and 11664% from the plant material.

CBN Creation – THC Remediation Step 2

For this exercise, the d9-THC extract was converted into cannabinol (CBN) using heat rather than cyclized into d8-THC, but a similar model could be used to account for this scenario. The conversion rate of the cannabinoids into CBN through heat degradation alone is low. Therefore, the model assumes half of the available cannabinoids in the d9-THC extract are converted to CBN. The entirety of the remaining portion of the cannabinoids are assumed to convert to some form of degradant rather than a portion getting destroyed. Data for THC destruction is shown in Image 7.

Image 7: Summary Data Table for THC Destruction through Degradation into CBN

Only after the CBN cyclization step has completed does the product that was the d9-THC extract become compliant and classifiable as a “hemp extract.”

Image 8: Summary Data Table for Reconciliation of the d9-THC Portion of the Hemp Extract

Throughout the process, from initial extraction to the final d9-THC remediation step, loss occurs. Of the 3 kg of d9-THC available in the plant material only 2.1 kg was recovered and converted to CBN. 0.9 kg was either lost to the equipment, destroyed in the process, attributable to the mass difference associated with decarboxylation, or was never extracted from the plant material in the first place. All of these potential areas of product loss should be identified, and their diversion risk fully assessed. Not every waste stream poses a risk of diversion, but some do; having a plan in place to handle waste the DEA considers a controlled substance is essential. Without a track-n-trace program following the d9-THC and identifying the potential risk of diversion would be impossible. The point of this is not to instill fear, instead the intention is to shed light on a very real issue “hemp extract” producers and state regulators need to understand to protect themselves and their marketplace from the DEA.
