After a delay due to their proficiency testing program roll out, the Colorado Marijuana Enforcement Division (MED) will now require all medical infused products and concentrates be tested for potency and homogeneity, starting November 1st, 2017.

After November 1st, all production batches of concentrates from medical product manufacturers will need to have a potency test before being sold, transferred or processed. The same goes for medical infused products, such as edibles and topicals. The homogeneity test refers to making sure THC or other active ingredients are distributed evenly throughout the product.

According to Alex Valvassori, author of a regulatory compliance-focused blog post on Complia’s website, these new testing requirements could lead to a surge in pricing, passed on to patients. He also recommends dispensaries take a close look at labels coming in from suppliers. They need to make sure potency data is listed clearly on the label to stay compliant.

Production batches created before November 1st are not required to meet the new testing regulations, but any and all batches after that date will be required to perform those tests.

Ask The Expert: Exploring Cannabis Laboratory Accreditation Part 1

By Aaron G. Biros

Laboratories throughout the world and in a variety of industries get accredited to demonstrate their competency. In the cannabis industry, some states are beginning to require it and many labs get accredited even if their state doesn’t require it. So what does accreditation mean and why is it so important?

The International Organization for Standardization (ISO) is a standard-setting organization that works to promote industrial and commercial standards. The standards set by ISO are designed to help prove a product’s safety and quality to a certain minimum level.

The ISO/IEC 17025:2005 standard sets specific requirements to demonstrate the competence of a lab for carrying out tests. It essentially shows customers or regulators that a lab has the skills and scientific know-how to perform testing, certifying the lab is capable. Accreditation means certifying a lab to that standard and is synonymous with both quality and competence of an organization.

Michelle Bradac, senior accreditation officer at A2LA

The American Association for Laboratory Accreditation (A2LA), founded in 1978, is a non-profit, internationally recognized accreditation body in the United States that offers laboratory and laboratory-related accreditation services and training. They have worked in the cannabis industry to accredit a number of cannabis laboratories to the ISO/IEC 17025:2005 standard. In this series of articles, we sit down with experts from A2LA to learn more about cannabis lab accreditation, why it’s so important and some of the challenges labs face when seeking accreditation.

In the first part of this series, we sit down with Michelle Bradac, senior accreditation officer at A2LA, to learn the basics. Michelle earned a bachelor’s degree in Biology at Towson State University and then attended Hood College, earning a master’s certificate in Regulatory Compliance in Biomedical Science. She has worked at A2LA for eight years, assisting in the accreditation of food testing, environmental testing and cannabis testing laboratories to ISO/IEC 17025, as well as performing quality system assessments. She also facilitates a number of accreditation programs including Field Sampling Measurement Organizations, STAC (Air Emissions) and Cannabis Testing. Bradac is also a member of the ASTM Cannabis Working Group and the ACIL Cannabis Working Group.

In the next part of this series, we will hear about specific requirements in states, some of the benefits of using ISO/IEC 17025 and the influx of start-up or novice testing laboratories.

CannabisIndustryJournal: What is Laboratory Accreditation? 

Michelle Bradac: Laboratory accreditation is a formal means of determining and recognizing the technical competence of laboratories to perform specific types of testing, via the use of an independent third party accreditation body. It provides laboratory users a mechanism to identify and select reliable testing organizations. Use of ISO/IEC 17025 as a basis for laboratory accreditation is internationally recognized as THE conformity assessment standard to which laboratories are accredited; it is used in the USA by both Public (State, local, federal (FDA, USDA, CDC, DoD and EPA) and private laboratories for testing of foods & feeds, drugs, cosmetics, tobacco, natural products and cannabis (among other materials and products).

CIJ: How does laboratory accreditation benefit the cannabis testing laboratory? 

Michelle: It provides a framework for continuous improvement and self-correction where the cannabis testing laboratory data management system is independently reviewed and blinded sample Proficiency Testing is encouraged.

CIJ: How does laboratory accreditation benefit the medical cannabis prescribing physician?

Michelle: The physician gains assurance that the dosage and concentrations of material being prescribed is what the label says it is and that the product is safe for use. This is especially important in working with patients that are immunocompromised.

CIJ: How does the testing of medical cannabis by an accredited laboratory benefit the patient?

Michelle: The patient gains increased confidence that the medication is going to be both safe and effective.

CIJ: What specific challenges does A2LA face in accrediting cannabis testing laboratories?

Michelle: Much of the typical infrastructure is lacking or only now being developed. This ranges from proficiency testing programs, Reference Material Producers, method development and sampling procedures. There is also difficulty in ensuring that laboratories are appropriately validating methods in states where cannabis product is not yet available.

CIJ: Why is A2LA the optimal choice for ensuring the quality and reliability of the results produced by medical marijuana testing laboratories?

Michelle: A2LA has by far the most experience as an accreditor of laboratories that perform testing of natural plant products. We have been performing assessments of and granting accreditation to these types of laboratories for over twenty years. This results in our staff and our assessor corps who are then able to provide valuable insight and technical sophistication that other accreditation bodies do not have. Specific to the cannabis industry, A2LA is also represented in all the major standards development organizations, tradeshows and industry groups; which strengthens our understanding of the industry and ability to assist our customers towards meeting their goal of obtaining accreditation.

Digipath Expands To California

In July, we sat down with the folks at Digipath, Inc. when they received their testing license in Nevada for the adult use market. In that conversation, they mentioned they were looking to expand into California.

According to a press release published September 25th, DigiPath, Inc. has entered a joint venture to establish their first cannabis-testing lab in California. They will be working with Don Ashley, an experienced real estate developer and cannabis entrepreneur, to launch Humboldt Botanical, LLC, conducting business under the name “Digipath Botanical Testing”.

Ashley says they expect to be fully operational by Q1 of 2018. “We expect to break ground on this project in the next few weeks and hope to be operational in early Q1 2018 just after the state-wide adult-use market is expected to launch, as we have already obtained approval from the local planning authorities for the entire complex,” says Ashley.

Todd Denkin, founder and president of Digipath

Todd Denkin, president of Digipath, is optimistic for California’s market and the coming regulations. “The state of California is estimated to be the single largest cannabis market in the U.S. Adult-use cannabis legislation was approved by California residents last November, and we expect these new regulations to be implemented in 2018,” says Denkin. “The good news for the industry is that the requirements for cannabis testing will be significant, and we are excited to partner with Don and his team to pursue this opportunity in Humboldt County.”

Ashley is contributing roughly $2 million to build and equip the lab with instrumentation, while Digipath Labs will manage and supervise operations at the lab. According to the press release, Digipath will provide a non-exclusive license to use its intellectual property for the operation of the lab. Digipath Labs will retain rights over all the scientific data generated in the lab.

Cindy Orser, PhD., chief science officer at Digipath

According to Cindy Orser, PhD., chief science officer at Digipath, that data will be put to good use. “Digipath Labs has developed an algorithm for use in strain authentication based largely on terpene profiling from our testing lab in Nevada and we are eager to further test our hypothesis with an expanded dataset from cannabis grown in Northern California,” says Orser.

While testing labs are primarily seen as safeguards for public health and safety, using data to correctly identify strains is a relatively new concept. “Digipath Labs is all about public health and safety through testing for adulterants,” says Orser. “Another component to quality is having confidence in product authenticity at the dispensary level. Not only is the consumer buying quality assured products but truth in advertising when it comes to strain nomenclature.”

Denkin says they were proactive in working toward getting the license early on. “Our partners have been dealing with the local regulators while we have been providing the proper SOP’s for the local government in order to receive the proper licensure in the area,” says Denkin. Taking their experience from Nevada to California, Orser says they have been asked to present to the California Toxicology Association on their experience with cannabis testing in the highly regulated marketplace of Nevada.

The laboratory in Humboldt is going to be part of a “cannabis industrial park,” alongside an R&D facility, oils/concentrate manufacturing center, health and wellness center, distribution and processing facility, tissue culture nursery, hemp clothing outlet, and coffee bistro, according to the press release.

Looking forward to growing their business, Denkin says they hope to launch a lab in Southern California. “We do expect to have a larger footprint in California because of the size of the market and are looking for locations in Southern California as well,” says Denkin. When asked about any new plans to expand elsewhere, Denkin says they’ll let us know. “We are continuing with our business plan and actively seeking the right mergers and acquisitions. Stay tuned.”

Nevada Cannabis Lab License Suspended

Last month, G3 Labs LLC, a Las Vegas-based cannabis-testing lab, had their license suspended for an unknown regulatory compliance issue. According to Stephanie Klapstein, spokeswoman for the Nevada Department of Taxation, the reason why their license was suspended is confidential. “We can’t disclose the details of the suspension, including anything about penalties,” says Klapstein.

When asked about the license suspension, Klapstein told us it was a compliance issue, but could not go into detail. “I can confirm that we did suspend G3’s license for compliance issues,” says Klapstein. “We are working with them to bring them back into compliance. In the meantime, they cannot operate.” Klapstein told the Las Vegas Review-Journal that the Nevada Department of Agriculture tested cannabis samples from the lab to determine if there was a need for a recall. She also confirmed with us that the compliance issue does not necessitate any product recalls.

According to the Las Vegas Review-Journal, this is the first time a cannabis business license is suspended in the state since the beginning of adult-use sales back in July of this year. Nevada’s cannabis regulations require independent lab testing of products before they reach shelves. That required testing includes checking for potency, microbials, pesticides, residual solvents, moisture content, growth regulators, Mycotoxins and foreign matter.

When we reached out to G3 Labs, they did not immediately respond to a request for comment.

Dr. Chao-Hsiung Tung, lab director at G3 Labs, told the Las Vegas Review-Journal that they couldn’t comment, based on advice from their legal counsel. “G3 Labs is actively sorting out the issues with the Department,” Dr. Tung told the Review-Journal in an email.

Emerald Scientific recently announced their proficiency-testing program, The Emerald Test, has been approved by Colorado as a third party provider for proficiency testing in licensed cannabis laboratories. The Emerald Test, held twice annually, is an inter-laboratory comparison and proficiency test (ILC-PT), allowing data to be collected pertaining to the performance of laboratories on a national scale. Proficiency testing is designed to measure how accurately laboratories perform and is a critical tool for quality assurance.

Colorado requires labs to participate in a proficiency-testing program in order to be certified to conduct required testing on cannabis and cannabis products for safety and quality. According to the press release, Colorado’s Marijuana Enforcement Division, under the Department of Revenue, conducted an evaluation process to determine which applicants could meet the performance standards for regulatory compliance concerning proficiency testing. The contract was awarded to Emerald Scientific following this evaluation process.

emerald test retailAccording to Ken Groggel, director of the Proficiency Testing Program at Emerald Scientific, a number of states have recognized the need for independent proficiency testing as a required piece of regulatory compliance. “The Emerald Test Inter-Laboratory Comparison/PT is state approved in Washington & Colorado for cannabis testing laboratory licensure,” says Groggel. “States with cannabis or hemp production, as well as labs in other countries are now actively participating in the Emerald Test as a tool for quality improvement, efficiency upgrades and product safety.” He says the Colorado Marijuana Enforcement Division has contracted with Emerald Scientific to provide third party PT programs for microbial contaminants, residual solvents and pesticides.

Ken Groggel, director of the Proficiency Testing Program at Emerald Scientific

Beginning in 2014, The Emerald Test has been offered twice a year and, in 2017, over 50 labs participated from 14 states and 2 countries. “Laboratories that have enrolled more than once have seen significant improvement in their results, an indicator of improved performance for industry customers,” says Groggel.

Proficiency testing is important for ensuring quality, safety and product content accuracy. “This should be the priority whether you are a grower, manufacturer, testing laboratory, regulatory entity, medical patient or adult use consumer,” says Groggel. It also helps labs meet regulatory requirements and achieve ISO 17025 accreditation. “Independent proficiency testing helps determine if the lab is able to deliver the services marketed to its customers,” says Groggel. “Regulatory agencies can use this information when licensing, monitoring & enforcing good science for public safety.”

As new states legalize cannabis and develop consumer protection regulations, proficiency testing programs can help labs demonstrate their commitment to responsible and accurate testing. “When PT results show the cannabis testing lab is capable it is up to the government to ensure accountability for performance on behalf of all its citizens,” says Groggel. Labs can enroll starting on September 25th in the Fall 2017 Emerald Test ILC/PT.

Canadian Company Recalls Contaminated Cannabis

Broken Coast Cannabis Ltd., a cannabis business located on Vancouver Island, issued a voluntary recall of three cannabis lots due to the detection of pesticides. According to the safety alert published on Health Canada’s website, the voluntary Type III recall follows an inspection of the facility back in March of this year.

A Type III recall means those products are not likely to cause negative health effects. Sampling of those three cannabis lots found a cannabis oil product in July to contain low levels of Myclobutanil and Spinosad.

Upon further testing, a cannabis leaf sample was found to contain 0.017 parts-per-million of Myclobutanil. A third party laboratory confirmed the presence of that fungicide, leading them to recall three lots of dried cannabis sold between July and December of 2016, according to that safety alert.

Spinosad, an insecticide, and Myclobutanil, a fungicide, are not authorized for use with cannabis plants per the Pest Control Products Act, however they are approved for use in food production. The health risks of ingesting either of those two chemicals are well documented. “Health Canada has not received adverse reaction reports related to Broken Coast Cannabis Ltd.’s products sold affected by the recall,” reads the safety alert. “Health Canada recommends that any individual affected by the recall immediately stop using the recalled product and to contact Broken Coast Cannabis Ltd., at the following number 1-888-486-7579.”

On Monday, August 28th, attendees of the Cannabis Science Conference descended on Portland, Oregon for a week of educational talks, networking and studying the science of cannabis. On Monday, Chalice Farms, an extracts and infused products company, hosted the full-day JCanna Boot Camp focused on a deep dive behind the scenes of a cannabis production facility. The Cannabis Science Conference, hosted by Josh Crossney, founder of JCanna, takes place August 28th to 30th.

Attendees touring an extraction setup

Attendees were split into five groups where they listened to a variety of educational sessions and toured the facility. A track focused on cultivation, led by Autumn Karcey, president of Cultivo, Inc., detailed all things facility design for cannabis cultivation, including an in-depth look at sanitation and safety. For example, Karcey discussed HVAC cleanliness, floor-to-ceiling sanitation and the hazards associated with negative pressure. These principles, while applicable to most cultivating facilities, applies particularly to commercial-scale grows in a pharmaceutical setting.

Sandy Mangan and Tristan DeBona demonstrating the grinding technique for sample prep

During one session, Sandy Mangan, accounts manager at SPEX Sample Prep and Tristan DeBona, sales specialist at SPEX Sample Prep, demonstrated the basics of sample preparation for detecting pesticides in infused products, such as gummies. That required using their GenoGrinder and FreezerMill, which uses liquid nitrogen to make gummies brittle, then pulverizing them to a powder-like substance that is more conducive for a QuEChERS preparation.

Joe Konschnik and Susan Steinike demonstrate the QuEChERS method

Joe Konschnik, business development manager at Restek, Susan Steinike, product-marketing manager at Restek and Justin Steimling, an analytical chemist at Restek, gave a demonstration of a full QuEChERS extraction of a cannabis sample for pesticide analysis, with attendees participating to learn the basics of sample preparation for these types of tests.

Following those were some other notable talks, including a tour of the extraction instruments and equipment at Chalice Farms, a look inside their commercial kitchen and a discussion of edibles and product formulation. Dr. Uma Dhanabalan, founder of Uplifting Health and Wellness, a physician with over 30 years of experience in research and patient care, led a discussion of physician participation, patient education and drug delivery mechanisms.

Amanda Rigdon, Emerald Scientific, showing some complex matrices in cannabis products

Amanda Rigdon, chief technical officer of Emerald Scientific, offered a demonstration of easy and adaptable sample preparation techniques for potency testing of infused product matrices. Rigdon showed attendees of the boot camp how wildly diverse cannabis products are and how challenging it can be for labs to test them.

The JCanna Canna Boot Camp is a good example of an educational event catered to the cannabis industry that offers real, hands-on experience and actionable advice. Before the two-day conference this week, the boot camp provided a bird’s eye view for attendees of the science of cannabis.
