2018 Food Safety Consortium

Save the Dates for the 6th Annual Food Safety Consortium conference in Schaumburg, IL, a summit of Food Safety and Quality Assurance (FSQA) industry experts and government officials. The 2018 Food Safety Consortium will have a cannabis track this year where topics will include: regulations, standards, cannabis food safety & quality and much more.

NCIA Releases Cannabis Testing Policy Guides

The National Cannabis Industry Association (NCIA) announced earlier this week the release of two white papers at their Cannabis Business Summit in San Jose, California. The first white paper, dedicated to cannabis testing policy, offers recommendations for state’s addressing cannabis testing, advising them on how to write rules for the testing market.“As wonderful as cannabis is, we’ll face a crisis together as an industry way too soon.  When it happens, the key will be how we respond to it,” says Moss.

The NCIA Policy Council is like a think tank for helping for and shape state and federal level policy related to cannabis. Kurshid Khoja, principal at Greenbridge Corporate Counsel and member of the Policy Council, says this release of the testing policy recommendations demonstrates how we can help shape policy on the state level. “As both an NCIA Board member and a member of the Policy Council, I am really excited about the Council’s work,” says Khoja. “Somewhat under the radar, the Policy Council is establishing itself as the think tank for the cannabis industry. On topics ranging from tax policy to pesticides to international competition, the Policy Council is churning out quality papers to raise awareness and educate policy makers in DC. With the release of its testing policy recommendations this week, the Policy Council is demonstrating that it could also help shape policy on the state level.”

The second white paper is meant to provide guidance to businesses dealing with crisis communications. The manual describes best practices in crisis communications, showing businesses how to identify and avoid potential public communications issues in the cannabis industry.

Jeanine Moss, Crisis Manual Subcommittee Chair of NCIA’s Marketing & Advertising Committee, says the creation of a crisis manual is meant to preempt problems we might face soon in the cannabis industry. “As wonderful as cannabis is, we’ll face a crisis together as an industry way too soon.  When it happens, the key will be how we respond to it,” says Moss. “That’s why we think it is so important for NCIA members to have an easy and practical guide that can not only help protect businesses during a crisis, but also the industry as a whole. This manual will help businesses prevent problems, keep issues from spiraling out of control, and share positive messages during times of stress.”

The guides will be presented this week at the NCIA’s Cannabis Business Summit & Expo in San Jose, California.

The Importance of Medical Cannabis Trials In Europe

By Marguerite Arnold

Calls for more testing have been a watchword of both cannabis reform advocates and opponents alike for many years.

However, now is a really good time for cannabis companies to consider sponsoring medical trials across Europe for their cannabis products. This is why:

The Current Environment On The Ground

Germany is Europe’s biggest consumer of both prescription medications and medical devices dispensed by prescription. It is, as a result, Europe’s most valuable drug market. And ground zero for every international cannabis company right now as a result.Targeting Germany for your latest pharmaceutical product is difficult no matter who you are.

Here, however, are a few problems that face every pharma manufacturer, far beyond cannabis. Targeting Germany for your latest pharmaceutical product is difficult no matter who you are.

  1. The vast majority by euro spending on all drugs and devices dispensed by prescription must be pre-approved. To add to this problem, before they can be prescribed, new drugs must get on the radar of doctors somehow. To put this in stark relief, the entire prescription drug and medical device annual spend is about 120 billion euros a year in Germany. Only 20 billion euros of that, however, may be obtained relatively easily (without pre-approval from an insurer). Preapproval also only comes when there is trialor other scientific evidence of efficacy.
  2. There are strict rules banning the advertising of prescription drugs to patients and highly limiting this outreach to doctors.
  3. There are strict rules prohibiting the use of the word “cannabis” to promote anything.
  4. There is a strong reliance on what is called “evidence-based medicine.” That means that large numbers of doctors and insurance company approvers need to see hard data that this drug or device actually works better than what is currently on the market.

How then, is a new drug supposed to get on the radar of those who prescribe the drug? Or patients?

If this sounds like an impossible situation to navigate, do not despair. There is a way out.

The Impact of the European Medicines Agency

This agency has been much in the news of late. Namely, the British do not want to exclude themselves from the regulatory umbrella of this organization.

Largely unknown outside Europe, this agency actually has a hugeinfluence on how drugs are brought into the region. Specifically, this is the EU-wide agency (aka the EMA) that both regulates all drugs within Europe, but has also, since 2016, been making clinical reports submitted by pharmaceutical companies, available to anyone who asks for them. That includes doctors, members of the public and of course, the industry itself.

In the middle of July, the agency also published a report on the success of its now three-year-old program, including the usage of its entry website. Conveniently written in English, it is possible to easily search new trial data, which, also now must be made public.

Medical trial data, in other words, that can be created by sponsored cannabis company backed trials.

It remains the best way to get patients, doctors and insurance companies familiar with new drugs. Or even new uses for old drugs in the case of cannabis.

Will Trials Move Legalization Discussions?

Of all the established cannabis companies now in operations with producton the ground, GW Pharmaceuticals has learned that this strategy can actually cut both ways.GW logo-2

However,there are no other cannabis companies in the position of GW Pharma – namely with a monopoly on a whole country (the UK), where it alone can legally grow cannabis crops and process the same into medication and further for very profitable export. In addition, even more disturbingly, and clearly an era that is coming to an end, the vast majority of British patients have been excluded from access to cannabis except in the case of GW Pharma products.

The current row over expanded medical use in the UK, in fact, was triggered by two things. The failure of the latest GW Pharma trial for drug resistant epilepsy in Eastern Europe. And the deliberate importation by several desperate families, of good old cannabis (CBD) oil into the UK. No medical processing required.

GW Pharma said their product Epidiolex (for the treatment of childhood epilepsy) is being considered by the European Medicines Agency

However, that is the UK.

Other cannabis companies can take a page out of the company’s handbook. All that is required for faster market entry, is a slightly altered recipe.

By sponsoring cannabis-related trials in each country they want to enter, starting with Germany, cannabis companies can literally put themselves on the medical map.

Why?

Because doctors, patients andother researchers will be easily able to see and access country-specific medical data on each use of cannabis covered by a trial, per EU country. All made possible, of course, by the new open door policy of the EMA.

Growing the Medical Market

While this may sound like an “expensive” proposition, there are really few other alternatives. And with no advertising budget, plus a marketing budget that must include outreach to everyone in the supply chain including doctors, distributors and even pharmacies, the trial approach in the end may be the most efficacious in broadening both the demand and market. Not to mention the cheaper option.

How such a trial strategy might be coordinated at a time when domestic cultivation is still on hold is still a question. However for those companies considering market entry and cultivation bid if not domestic processing strategies for their products is an industry strategy that will pay off in spades.

Its role in the legalization of cannabis as medicine, as well as the speedier introduction of new drugs overall into the European system,cannot be underestimated, even if it is currently underutilized by the cannabis industry specifically now.

How to Protect Your Trademarks When You Can’t Protect Your Trademarks

By David Kluft

Federal trademark registrations are invaluable tools for emerging businesses. They put the world on notice of a company’s name; they can secure nationwide priority over others using similar names; they distinguish a product in the marketplace; they provide crucial advantages in trademark infringement lawsuits; and they are instrumental in building goodwill. But if you sell cannabis, a federal trademark registration will not do any of those things for you … because you can’t get one.

Someday, the USPTO policy may change and there could be a gold rush for federal cannabis trademark registrations.The United States Patent and Trademark Office (USPTO) continues to refuse to register federal trademarks for cannabis businesses, even if the sale of cannabis is legal in the state where the businesses are located. The USPTO’s reasoning goes something like this: federal trademark law allows for the registration of trademarks associated with goods in “lawful” commerce, which means that the goods are not illegal under federal law. Cannabis, and its psychoactive component, THC, remain Schedule I substances under the federal Controlled Substances Act (CSA). Therefore, irrespective of state laws to the contrary, and irrespective of whether the federal law is actually enforced, the manufacture and sale of cannabis is not “lawful” commerce.

This reasoning is of fairly recent vintage. In 2009, by which time about fifteen states had legalized medical cannabis, Attorney General Eric Holder announced that the Drug Enforcement Administration would cease raids on state-sanctioned medical cannabis facilities. The USPTO followed Holder’s lead in 2010 and created a new category of acceptable goods and services for marks related to “medical marijuana.” Within months, however, the USPTO had retreated from this “mistake” and changed its practice manual expressly to preclude such registrations.

Many argue that the USPTO’s position is unjustifiable as a matter of public policy. Making it easier to infringe the trademarks of state-sanctioned businesses does not advance the purposes of the CSA, and it directly undermines a key goal of trademark law, which is to prevent the proliferation of confusingly similar trademarks. But the merits of these arguments have been lost on the USPTO, which continues to refuse to register marks for anything it perceives to be prohibited by the CSA.

So if you own a cannabis business, what can you do to protect your goodwill while the federal government maintains its current policy? Below are some ideas. Admittedly, none of them– individually or collectively – is a substitute for federal registration. But each of them is better than nothing, and all of them may help to establish your ownership and priority when and if the USPTO changes its policy.

  1. State Trademark Registrations. Each state has its own trademark registration system. State registration may offer protection from infringers within the state, or at least within the parts of the state where the registrant operates, and for that reason alone it is probably worth the small cost involved. However, state registration will have little to no efficacy outside the state. You cannot use a State A registration to file a lawsuit in State B, or to stop infringement in State B, or even to prevent conflicting registrations in State B. Additionally, most state trademark registrants, unlike federal registrants, do not benefit from presumptions of validity and ownership in the litigation context.
  2. Related Federal Registrations. Many cannabis businesses also pursue federal registrations for whatever aspects of their business are not prohibited by the CSA. For example, even though the USPTO refused the POWERED BY JUJU mark for cannabis vaporizers (because it was CSA-prohibited “paraphernalia”), it allowed the same company to register the same mark for “vaporizers for smoking purposes not for use with cannabis.” The USPTO has also allowed registrations for cannabis-related business consulting (e.g., CANNACARD; PRAIRIEJUANA); investment analysis (e.g., FORTUNE420); clothing (e.g., CANNABIS COUTURE, THE MARIJUANA COMPANY); and for CBD – as opposed to THC – derivatives (e.g., CBD LIQUID GOLD). Once the USPTO permits federal registrations for cannabis marks and the inevitable disputes over ownership arise, such federal registrations for these related products and services are likely to be highly persuasive evidence in the registrants’ favor. Moreover, even in the current legal climate, federal registrations (especially when cited in a demand letter) are of great practical use in convincing others not to use confusingly similar marks.
  3. Common Law Unfair Competition. Unfair competition is a state common law cause of action that was a precursor to modern trademark law, and it is still available to protect commercial goodwill even in the absence of a state or federal trademark registration. However, unfair competition law has similar territorial restrictions as state registration. In some cases, the protected territory may be even narrower, limited only to the area within which the plaintiff can prove consumer recognition of the mark.
  4. Other Intellectual Property Protection. Copyright law, unlike federal trademark law, has no “lawful” commerce requirement, and the U.S. Copyright Office regularly issues registrations for cannabis-related copyrights. While copyright will not protect a short phrase such as a business name, it will protect a creative logo design or original packaging, and can be very effective when it comes to getting infringing uses taken down from the internet. Note also that the USPTO does not appear to have the same qualms about legality when it comes to patents, and it often grants patent protection to useful, new and non-obvious inventions related to the cannabis industry.
  5. Save stuff. Finally, if you do nothing else, save stuff. Document that first sale; keep a copy of that first shipping invoice; and save that file containing your original packaging design. Someday, the USPTO policy may change and there could be a gold rush for federal cannabis trademark registrations. Your lawyer is going to ask you for proof of your first uses of the mark, and you don’t want your response to be a glassy stare. So keep your eyes on the eventual prize and stay ready.

Quality Plans for Lab Services: Managing Risks as a Grower, Processor or Dispensary, Part 3

By Dr. Edward F. Askew
No Comments
Dr. Ed Askew

Editor’s Note: The views expressed in this article are the author’s opinions based on his experience working in the laboratory industry. This is an opinion piece in a series of articles designed to highlight the potential problems that clients may run into with labs. 


In the last two articles, I discussed the laboratory’s first line of defense (e.g. certification or accreditation) paperwork wall used if a grower, processor or dispensary (user/client) questioned a laboratory result and the conflicts of interest that exist in laboratory culture. Now I will discuss the second line of defense that a laboratory will present to the user in the paperwork wall: Quality Control (QC) results.

Do not be discouraged by the analytical jargon of the next few articles. I suggest that you go immediately to the conclusions to get the meat of this article and then read the rest of it to set you on the path to see the forest for the trees.

QC in a laboratory consists of a series of samples run by the laboratory to determine the accuracy and precision of a specific batch of samples. So, to start off, let’s look at the definitions of accuracy and precision.QC Charts can provide a detailed overview of laboratory performance in a well-run laboratory.

According to the Standard Methods for the Examination of Water and Wastewater:

Accuracy: estimate of how close a measured value is to the true value; includes expressions for bias and precision.

Precision: a measure of the degree of agreement among replicate analyses of a sample.

A reputable laboratory will measure the Accuracy and Precision of QC samples in a batch of user samples and record these values in both the analytical test report issued to the user and in control charts kept by the laboratory. These control charts can be reviewed by the user if they are requested by the user. These control charts record:

Accuracy (means) chart: The accuracy chart for QC samples (e.g., LRB, CCV, LFBs, LFMs, and surrogates) is constructed from the average and standard deviation of a specified number of measurements of the analyte of interest.

Precision (range) chart: The precision chart also is constructed from the average and standard deviation of a specified number of measurements (e.g., %RSD or RPD) for replicate of duplicate analyses of the analyte of interest.

Now, let’s look at what should be run in a sample batch for cannabis analyses. The typical cannabis sample would have analyses for cannabinoids, terpenes, microbiological, organic compounds, pesticides and heavy metals.

Each compound listed above would require a specific validated analytical method for the type of matrix being analyzed. Examples of specific matrixes are:

  • Cannabis buds, leaves, oil
  • Edibles, such as Chocolates, Baked Goods, Gummies, Candies and Lozenges, etc.
  • Vaping liquids
  • Tinctures
  • Topicals, such as lotions, creams, etc.

Running QC analyses does not guarantee that the user’s specific sample in the batch was analyzed correctly.

Also, both ISO 17025-2005 and ISO 17025-2017 require the use of a validated method.

ISO 17025-2005: When it is necessary to use methods not covered by standard methods, these shall be subject to agreement with the customer and shall include a clear specification of the customer’s requirements and the purpose of the test and/or calibration. The method developed shall have been validated appropriately before use.

ISO 17025-2017: The laboratory shall validate non-standard methods, laboratory-developed methods and standard methods used outside their intended scope or otherwise modified. The validation shall be as extensive as is necessary to meet the needs of the given application or field of application.

Validation procedures can be found in a diverse number of analytical chemistry associations (such as AOACand ASTM) but the State of California has directed users and laboratories to the FDA manual “Guidelines for the Validation of Chemical Methods for the FDA FVM Program, 2nd Edition, 2015

The laboratory must have on file for user review the following minimum results in an analytical statistical report validating their method:

  • accuracy,
  • limit of quantitation,
  • ruggedness,
  • precision,The user must look beyond the QC data provided in their analytical report or laboratory control charts.
  • linearity (or other calibration model),
  • confirmation of identity
  • selectivity,
  • range,
  • spike recovery.
  • limit of detection,
  • measurement uncertainty,

The interpretation of an analytical statistical report will be discussed in detail in the next article. Once the validated method has been selected for the specific matrix, then a sample batch is prepared for analysis.

Sample Batch: A sample batch is defined as a minimum of one (1) to a maximum of twenty (20) analytical samples run during a normal analyst’s daily shift. A LRB, LFB, LFM, LFMD, and CCV will be run with each sample batch. Failure of any QC sample in sample batch will require a corrective action and may require the sample batch to be reanalyzed. The definitions of the specific QC samples are described later.

The typical sample batch would be set as:

  • Instrument Start Up
  • Calibration zero
  • Calibration Standards, Quadratic
  • LRB
  • LFB
  • Sample used for LFM/LFMD
  • LFM
  • LFMD
  • Samples (First half of batch)
  • CCV
  • Samples (Second half of batch)
  • CCV

The QC samples are defined as:

Calibration Blank: A volume of reagent water acidified with the same acid matrix as in the calibration standards. The calibration blank is a zero standard and is used to calibrate the ammonia analyzer

Continuing Calibration Verification (CCV): A calibration standard, which is analyzed periodically to verify the accuracy of the existing calibration for those analytes.

Calibration Standard: A solution prepared from the dilution of stock standard solutions. These solutions are used to calibrate the instrument response with respect to analyte concentration

Laboratory Fortified Blank (LFB): An aliquot of reagent water or other blank matrix to which known quantities of the method analytes and all the preservation compounds are added. The LFB is processed and analyzed exactly like a sample, and its purpose is to determine whether the methodology is in control, and whether the laboratory is capable of making accurate and precise measurements.

Laboratory Fortified Sample Matrix/Duplicate (LFM/LFMD) also called Matrix Spike/Matrix Spike Duplicate (MS/MSD): An aliquot of an environmental sample to which known quantities of ammonia is added in the laboratory. The LFM is analyzed exactly like a sample, and its purpose is to determine whether the sample matrix contributes bias to the analytical results. The background concentrations of the analytes in the sample matrix must be determined in a separate aliquot and the measured values in the LFM corrected for background concentrations (Section 9.1.3).Laboratories must validate their methods.

Laboratory Reagent Blank (LRB): A volume of reagent water or other blank matrix that is processed exactly as a sample including exposure to all glassware, equipment, solvents and reagents, sample preservatives, surrogates and internal standards that are used in the extraction and analysis batches. The LRB is used to determine if the method analytes or other interferences are present in the laboratory environment, the reagents, or the apparatus.

Once a sample batch is completed, then some of the QC results are provided in the user’s analytical report and all of the QC results should be recorded in the control charts identified in the accuracy and precision section above.

But having created a batch and performing QC sample analyses, the validity of the user’s analytical results is still not guaranteed. Key conclusion points to consider are:

  1. Laboratories must validate their methods.
  2. Running QC analyses does not guarantee that the user’s specific sample in the batch was analyzed correctly.
  3. QC Charts can provide a detailed overview of laboratory performance in a well-run laboratory.

The user must look beyond the QC data provided in their analytical report or laboratory control charts. Areas to look at will be covered in the next few articles in this series.

Tree of Knowledge Inc. Acquires 5% of NYSK Holdings

By Marguerite Arnold
No Comments
TOK_logo

The Canadian cannabis community has just gotten a new member. Tree of Knowledge, Inc. just became Canada’s newest public cannabis company. The company is also planning on raising $10 million in private placement capital. According to the company’s most current pitch deck, the planned use of proceeds includes $6.5 million for new capex expenditures in Canada and Macedonia plus new product development. The rest is slated for patient and doctor outreach including via social media, new hires and working capital.

Who Is Tree of Knowledge Inc.?

Founded originally in Washington State in 2015, today TOK has a global market presence with CBD products on three continents and is already positioning itself to run with the big boys on the international scene, just on its CBD footprint. In the online marketplace, they are doing business as EVR CBD. That includes state markets in the United States, Europe, South America, Australia and China.

The company also has a distinguished board that includes doctors to former professional sports stars. As of April, the company engaged in a reverse merger with Courtland Capital, a Nevada subsidiary company.TOK_logo

And as of July 2018, the company purchased 5% of NYSK Holdings – a rapidly establishing Macedonian start-up with an eye to the European market – starting with Germany.

Who Is NYSK Holdings?

NYSK Holdings is absolutely on an upward trajectory. The company, founded by Americans with strong ties to the home country along with local partners, broke ground in Skopje, Macedonia last year.

Company principals have been exploring entry into the European market ever since (Macedonia may be in the Balkans, but it is technically not part of the EU). Significantly, this also means that producers there are used to meeting European specs for import purposes, if not hopeful EU inclusion.

NYSK holdingsLike other EU partners in the west however, (notably Spain and Portugal) labour rates are also much lower than in Germany. This creates a new avenue into the EU and the German market, which is now going to be an import-dominant one until 2020.

What is even more interesting about NYSK? They produce GMP-certified product – both THC and CBD. They have been looking for partners for most of this year. They also had a booth at the ICBC in Berlin, an experience that they found highly satisfactory.

Their strategic importance to TOK is also large. NYSK brings, for the first time, THC products and high-tech processing capacity adjacent to the European Union to a firm with a global footprint.

They might, in other words, have been Europe’s most under-priced production facility. Don’t expect that to last long.

What Is Interesting About The Move

One glance at TOK’s founders, board, andadvisors is enough to establish that this is a company of mostly older Gen X and younger Boomer heavy hitters from other industries who are pooling resources and knowledge to step into a global medical cannabis space. Smartly.

For example, the focus on dosing control, trials and an operational, GMP-certified production facility in Macedonia, plus their Canadian footprint, makes TOK and their partners well suited for “European invasion.” So does their first product – a CBD-based sleep aid.

NYSK facility

This creates, in other words, a company with Canadian and Macedonian production, American entry and global reach, including into countries other cannabis companies have so far not breached (see China), with an interesting, low-cost, lower risk entry profile. Their expanded market entry is also occurring right at a time when Europe, including the about to be Brexited UK, is now moving forward on medical reform sans very much local production.

Perhaps this comes from the experience of the principals. TOK Cofounder Michael Caridi started his involvement in the cannabis industry in Washington State in 2014 after a successful real estate and promotions career on the East Coast (New York) and experience in ex-im. However, Caridi rapidly grew disillusioned with the state’s focus if not an obsessionon a more recreational space than medical users. He and Brian Main, now president of US operations, founded TOK a year later. Current CEO, John-Paul Gaillard, has a history that includes the creator of the Marlboro Classics brand and a stint as the CEO of Nestle Nespresso who put the idea on the map if not kitchen counters globally.

No newbies here when it comes to global market strategies, penetration and experience.

Both companies to watch, for sure.

Centrifugal Partition Chromatography Paves the Way for Safer, More Standardized Cannabidiol Drugs

By Lauren Pahnke
No Comments
Lauren Pahnke

Imagine this: you are taking medication for cancer pain. One day, it works perfectly. The next, you feel no relief. On some days, you need to take three doses just to get the same effect as one. Your doctor can’t be completely positive how much active ingredient each dose contains, so you decide for yourself how much medication to take.

Doesn’t seem safe, right? It is crucial that doctors know exactly what they are prescribing to their patients. They must know that their patients are receiving the exact same dose of medication in their prescription each time they take it, and that their medication contains only the intended ingredients.

consistency is key to creating products that are safe for consumers.In the cannabis industry, lack of certainty on these important factors is a major problem for drug manufacturers as they attempt to incorporate cannabidiol (CBD), a compound found in cannabis that has no psychoactive effects but many medical benefits, into pharmaceutical drugs.

When using these compounds as medications, purity is essential. Cannabis contains a wide variety of compounds. Delta-9 tetrahydrocannabinol (THC) is the most well-known compound and its main psychoactive one1. Safety regulations dictate that consumers know exactly what they are getting when they take a medication. For example, their CBD-based medications should not contain traces of THC.

The cannabis industry greatly needs a tool to ensure the consistent extraction and isolation of compounds. In 2017, the cannabis industry was worth nearly $10 billion, and it is expected to grow $57 billion more in the next decade2. As legalization of medical cannabis expands, interest in CBD pharmaceuticals is likely to grow.

If compounds such as CBD are going to be used in pharmaceutical drugs, consistency is key to creating products that are safe for consumers.

CBD’s Potential

CBD is a non-psychoactive compound that makes up 40 percent of cannabis extracts1. It is great for medical applications because it does not interfere with motor or psychological function. Researchers have found it particularly effective for managing cancer pain, spasticity in multiple sclerosis, and specific forms of epilepsy3.

Figure 1: The chemical structure of cannabidiol.
Figure 1: The chemical structure of cannabidiol.

Other compounds derived from cannabis, such as cannabichromene (CBC) and cannabigerol (CBG), may also be beneficial compounds with medical applications. CBC is known to block pain and inflammation, and CBG is known for its use as a potential anti-cancer agent1.

Along with these compounds that provide medical benefits, there are psychoactive compounds that are used recreationally, such as THC.

“It will definitely be an advantage to have cannabis-based medications with clearly defined and constant contents of cannabinoids,” says Kirsten Müller-Vahl, a neurologist and psychiatrist at Hannover Medical School in Germany.

Creating a Standard Through Centrifugal Partition Chromatography

To obtain purified compounds from cannabis, researchers need to use technology that will extract the compounds from the plant.

Many manufacturers use some sort of chromatography technique to isolate compounds. Two popular methods are high performance liquid chromatography (HPLC) and flash chromatography. These methods have their places in the field, but they cannot be effectively and cost-efficiently scaled to isolate compounds. Instead, HPLC and flash chromatography may be better suited as analytical tools for studying the characteristics of the plant or extract. As cannabis has more than 400 chemical entities4, compound isolation is an important application.

This method is highly effective for achieving both high purity and recovery.Although molecules such as CBD can be synthesized in the lab, many companies would rather extract the compounds directly from the plant. Synthesized molecules do not result in a completely pure compound. The result, “is still a mixture of whatever cannabinoids are coming from a particular marijuana strain, which is highly variable,” says Brian Reid, chief scientific officer of ebbu, a company in Colorado that specializes in cannabis purification.

Currently, there is only one method available to researchers that completely allows them to isolate individual compounds: centrifugal partition chromatography (CPC).

The principle of CPC is similar to other liquid chromatography methods. It separates the chemical substances as the compounds in the mobile phase flow through and differentially interact with the stationary phase.

Where CPC and standard liquid chromatography differs is the nature of the stationary phase. In traditional chromatography methods, the stationary phase is made of silica or other solid particles, and the mobile phase is made of liquid. During CPC, the stationary phase is a liquid that is spun around or centrifuged to stay in place while the other liquid (mobile phase) moves through the disc. The two liquid phases, like oil and water, don’t mix. This method is highly effective for achieving both high purity and recovery. Chemists can isolate chemical components at 99 percent or higher purity with a 95 percent recovery rate5.

“CPC is ideal for ripping a single active ingredient out of a pretty complex mixture,” says Reid. “It’s the only chromatographic technique that does that well.”

The Need for Pure Compounds

High levels of purity and isolation are necessary for cannabis to be of true value in the pharmaceutical industry. Imagine relying on a medication to decrease your seizures, and it has a different effect every time. Sometimes there may be traces of psychoactive compounds. Sometimes there are too much or too little of the compound that halts your seizures. This is not a safe practice for consumers who rely on medications.“It’s hard to do studies on things you can’t control very well.”

Researchers working with cannabis desperately need a technology that can extract compounds with high purity rates. It is hard to run a study without knowing the precise amounts of compounds used. Reid uses a Gilson CPC 1000 system at ebbu for his cannabinoid research. With this technology, he can purify cannabinoids for his research and create reliable formulations. “Now that we have this methodology dialed in we can make various formulations —whether they’re water-soluble, sublingual, inhaled, you name it —with very precise ratios of cannabinoids and precise amounts of cannabinoids at the milligram level,” says Reid.

Kyle Geary, an internist at the University of Illinois at Chicago, is currently running a placebo-controlled trial of CBD capsules for Crohn’s disease. This consistent isolation is helpful for his research, as well. “Ideally, the perfect study would use something that is 100 percent CBD,” says Geary. “It’s hard to do studies on things you can’t control very well.”

The State of the Industry

While CBD is not considered a safe drug compound under federal law in the United States6, 17 states have recently passed laws that allow people to consume CBD for medical reasons7. Half of medicinal CBD users solely use the substance for treatment, a recent survey found8. As the industry quickly grows, it is crucial that consumer safety protocol keeps pace.

In June, the US Food and Drug Administration (FDA) approved the first drug that contains a purified drug substance from cannabis, Epidiolex9. Made from CBD, it is designed to treat Dravet Syndrome and Lennox-Gastaut syndrome, two rare forms of epilepsy. FDA Commissioner Scott Gottlieb said in the news release that although the FDA will work to support the development of high-quality cannabis-based products moving forward, “We are prepared to take action when we see the illegal marketing of CBD-containing products with serious, unproven medical claims. Marketing unapproved products, with uncertain dosages and formulations can keep patients from accessing appropriate, recognized therapies to treat serious and even fatal diseases.”

The industry should be prepared to implement protocols to ensure the quality of their CBD-based products. The FDA has issued warnings in recent years that some cannabinoid products it has tested do not contain the CBD levels their makers claim, and consumers should be wary of such products10. It’s hard to know when or if the FDA will begin regulating CBD-based pharmaceuticals. However, for pharma companies serious about their reputation, there is only one isolation method that creates reliable product quality: CPC.

Food Safety: Do You Know What Is In Your Water?

Water is essential for life and it is an important part of agriculture and food manufacturing. Water has many uses in the cannabis industry. Among the most common uses are irrigation, ingredient/product processing and cleaning processes.

Water can be the carrier of pathogenic microorganisms and chemicals that can be transferred to food through agriculture and manufacturing practices. Poor quality water may have a negative impact in food processing and potentially on public health. Therefore, development and implementation of risk management plans that ensure the safety of water through the controls of hazardous constituents is essential to maintain the safety of agricultural and manufactured food or cannabis products.

Chemicals can enter the water stream through several sources such as storm water, direct discharge into fields and city water treatment plans.Although there no current regulations regarding the water used in cannabis cultivation and processing, it is highly recommended that the industry uses potable water as standard practice. Potable water is water that is safe for drinking and therefore for use in agriculture and food manufacturing. In the United States, the Environmental Protection Agency (EPA) sets the standards for water systems under the Safe Drinking Water Act (SDWA.)The regulations include the mandatory levels defined as Maximum Contaminant Levels (MCLs) for each contaminant that can be found in water. Federal Drinking Water Standards are organized into six groups: Microorganisms, Disinfectants, Disinfection Byproducts, Inorganic Chemicals, Organic Chemicals and Radionuclides. The agriculture and food manufacturing industry use the SDWA as a standard to determine water potability. Therefore, water testing forms part of their routine programs. Sampling points for water sources are identified, and samples are taken and sent to a reputable laboratory to determine its quality and safety.

Determining the safety of the water through microbiological testing is very important. Pathogens of concern such as E. coli, Salmonella, Cryptosporidium parvum and Cyclospora sp. can be transmitted to food through water. These pathogens have been known to be lethal to humans, especially when a consumer’s immune system is compromised (e.g. cancer patients, elderly, etc.) If your water source is well, the local state agency may come to your facility and test the water regularly for indicator organisms such as coliforms. If the levels are outside the limit, a warning will be given to your company. If your water source is the city, regular testing at the facility for indicator microorganisms is recommended. In each case, an action plan must be in place if results are unfavorable to ensure that only potable water is used in the operations.

Chemical Testing (Disinfectants, Disinfection Byproducts, Inorganic Chemicals, Organic Chemicals and Radionuclides) 

Chemicals can enter the water stream through several sources such as storm water, direct discharge into fields and city water treatment plans. Although, there are several regulations governing the discharge of chemicals into storm water, fields and even into city water treatment plants, it is important that you test your incoming water for these chemicals on a regular basis. In addition, it is important that a risk assessment of your water source is conducted since you may be at a higher risk for certain components that require testing. For example, if your manufacturing facility is near an agricultural area, pesticides may enter the surface water (lakes, streams, and rivers) or the aquifer (ground water) through absorption into the ground or pollution. In this case, you may be at higher risk for Tetrahalomethanes (THMs), which are a byproduct of pesticides. Therefore, you should increase the testing for these components in comparison to other less likely to occur chemicals in this situation. Also, if your agriculture operation is near a nuclear plant, then radionuclides may become a higher risk than any of the other components.

GMPFinally, in addition to the implementation of risk management plans to ensure the safety of water, it is highly recommended that companies working in food manufacturing facilities become familiar with their water source to ensure adequate supply to carry on their operations, which is one of the requirements under the 21 CFR 117. Subpart B – Current Good Manufacturing Practices (cGMPs) for food manufacturers under the Preventive Controls for Human Foods Rule that was enacted under the Food Safety Modernization Act in 2015. Also, adequate supply is part of the Good Agricultural Practices (GAP) The EPA has created a program that allows you to conduct a risk assessment on your water source. This program is called Source Water Protection. It has six steps that are followed to develop a plan that not only protect sourcing but also ensures safety by identifying threats for the water supply. These six steps are:

  1. Delineate the Source Water Protection Area (SWPA): In this step a map of the land area that could contribute pollutants to the water is created. States are required to create these maps, so you should check with local and/or state offices for these.
  2. Inventory known and potential sources of contamination: Operations within the area may contribute contaminants into the water source. States usually delineates these operations in their maps as part of their efforts to ensure public safety. Some examples of operations that may contribute to contaminants into the water are: landfill, mining operations, nuclear plants, residential septic systems, golf courses, etc. When looking at these maps, be sure that you verify the identified sources by conducting your own survey. Some agencies may not have the resources to update the maps on a regular basis.
  3. Determine the susceptibility of the Public Water Source (PWS) to contaminate sources or activities within the SWPA: This is basically a risk assessment. In here you will characterize the risk based on the severity of the threat and the likelihood of the source water contamination. There are risk matrices that are used as tools for this purpose.
  4. Notify the public about threats identified in the contaminant source inventory and what they mean to the PWS: Create a communication plan to make the State and local agencies aware of any findings or accidents in your operation that may lead to contamination of the PWS.
  5. Implement management measures to prevent, reduce or eliminate risks to your water supply: Once risks are characterized, a plan must be developed and implemented to keep risks under control and ensure the safety of your water.
  6. Develop contingency planning strategies that address water supply contamination or service interruption emergencies: OSHA requires you to have an Emergency Preparedness Plan (EPP). This plans outlines what to do in case of an emergency to ensure the safety of the people working in the operation and the continuity of the business. This same approach should be taken when it comes to water supply. The main questions to ask are: a) What would we do if we find out the water has been contaminated? b) What plan is in place to keep the business running while ensure the safety of the products? c) How can we get the operation back up and running on site once the water source is re-stablished?

The main goal of all these programs is having safe water for the operations while keeping continuity of the business in case of water contamination.

German Authorities Will Issue New Cannabis Cultivation Bid

By Marguerite Arnold

According to Kermit the Frog, it’s never easy being green. It is also tough to be “first” in the cannabis biz. Anywhere.

One of the most remarkable features of the first years of state-level legalization in the U.S. was the sheer number of mistakes by the authorities in issuing licenses and bids for state-sanctioned cultivation and dispensation once the voters had forced legalization. There were several state-level “redos” and lots of legal mumbo jumbo thrown around as the green-rush kicked off at the state level.The real news? There is going to be a completely new one.

Fast-forward a couple of years and it is clear this is not just an issue of the confused state of legalization in the U.S.

Canada too, on a federal recreational level, has moved forward in fits and starts. And even though a fall start date to the market has now been enshrined into law, the continued moving target of the same has been a topic of fraught conversations and bargaining ever since the country decided to move ahead with full Monty recreational.

Across the pond, things are not going smoothly on the cannabis front. In the first week of July, the much stalled medical cultivation bid in Germany finally came to a limpid end. It remains to see if there will be any legal “bangs” as it whimpers away.

The real news? There is going to be a completely new one.

A Do-Over

According to documents obtained by Cannabis Industry Journal, the Bundesinstitut für Arzneimittel und Medizinprodukte (or BfArM) issued letters to original bid respondents in the first week of July. The letters appear to have been sent to all parties who originally applied to the first bid – far from the final top runners.

The translation, from German reads:

“We hereby inform you that we have withdrawn the above-mentioned award procedure…and intend to initiate a new award in a timely manner.”

The letter cited the legal decision of March 28 this year by the Düsseldorf Higher Regional Court as the reason the agency cannot award the contract. Specifically, because of “necessary changes to the tender documents…inparticular with regard to time, we have decided to cancel the procedure altogether and initiate a new award procedure.”

Per the letter, the new procedure will be published in the Official Journal of the EU. No date was mentioned.

An Expensive Surprise and a Global Response

Conventional wisdom in the industry about the fate of the first bid has been mixed since last September when the first hint of lawsuits against the procedure began to circulate. Highly placed sources within the industry have long had their doubts about the bid’s survivability, although nobody will talk on the record. The bid process is supposed to be secret.However, it is clear that another bid will be issued

Furthermore, for the last 9 months, BfArM has maintained that the agency would go full-steam ahead with the original tender. None of the major firms contacted by CIJ about this notification would confirm that they had received a similar letter, nor would they comment.

However, it is clear that another bid will be issued. Further, this time, it is also obvious to the extent that it was not before, the applicants will indeed hail from all points of the globe. On top of that, those who are qualified to respond and who missed it last time are unlikely to sit the bid out this time around.

German Parliament Building

It remains unclear of course, what the response of the finalists to the first bid will be. Including, theoretically,legal action forpotential damages. BfArM was, technically, held at fault by the court. This means that all the companies who made it to the previous “final round” have now suffered at a minimum, an expensive time delay where other outlays of cash were also required. That includes the leasing and retrofitting of high security real estate, but of course,is not limited to the same. If any of these firms do not obtain the bid in the second go around, will they sue?

At press time, there were no cannabis industry companies willing to comment on the matter as this is still a “secret” process – even if it now apparently has come to an end for this round.

Who Is Likely To Be a Major Contender This Time?

German firms who were sleeping the last time this opportunity arose (or brushed it off as a “stigmatized” opportunity) are not likely to sit the second tender offer out. Especially given advancements in legalization if not the industry both in Europe and globally in the period of time the bid has stalled.

Add to that Canadians, Dutch, Israeli and Uruguayan firms, and the mix of applicants this time is likely to be the who’s who of the global cannabis industry. Americans are still not qualified to participate (with experience at least). Why? No federal reform.Domestic cannabis will not be harvested in Germany until at least 2020. 

It is also likely to be even more expensive. Not to mention require easy and quick access to European-based or at least easily confirmable pools of cash. It is conceivable that successful applications this time around will not only have to prove that they have a track record in a federally legal jurisdiction but will also have to be able to quickly access as much as 100 million euros. And there are not many cannabis companies, yet, who can do that, outside of the presumed top 10 finalists to the bid.

Will Bid Respondents Be Limited To “Just” the Cannabis Industry?

It is, however, absolutely possible that this time around the bid could include a more established pharmaceutical player or two who realizes that the medical market here has absolutely proved itself. Within the space of a year, according to the most recent “market report” on the industry (from the perspective of one of the country’s largest statutory insurance companies – Techniker Krankenkasse), there are now just over 15,000 patients.

Cannabis, in other words, is no longer an “orphan drug.” It is also still, however, considered a narcotic. For that reason, seasoned European and German players may upset the market even more with an entry via this tender bid.

Here is what is certain for now. Domestic cannabis will not be harvested in Germany until at least 2020. And until that time, it will be a growing, but import-based market.

Collaborative Health Model to Advance Cannabis Research

By Rob Adelson

The projected growth of the legal cannabis market is astounding. According to a report from BDS Analytics, the industry is expected to grow from $9.2B to $47.3B in 2027 in North America, with medical cannabis contributing 33% of that overall growth. While this number is impressive for an industry still in its infancy, I have reason to believe it can be much higher.

In the pharmaceutical industry, treatment of pain and insomnia represent an annual revenue exceeding $140B; concurrently, studies have shown cannabis to be an effective treatment for both conditions. If medical cannabis can capture 10% of that revenue over the next ten years, it essentially doubles the current estimates mentioned above.

So, what stands in our way? Education.

To gain acceptance from the medical community, physicians need to better understand the plant and its therapeutic benefits. To do so, they need more substantial data to prove cannabis’ efficacy before prescribing it to their patients. However, federal illegalities have prevented government-mandated clinical studies, but I believe there’s another way.

By adopting a collaborative health care model, patients and caregivers can work together to track the effectiveness of their cannabis treatments and share their learnings with the larger medical community.  With the right tools in place, we can fast-track the research process and provide physicians and politicians with the information they need to make this medicine more approachable and accessible to those who could benefit from it.

By harnessing the power of the community, we can apply learnings from one patient’s cannabis use to help countless others.The Spine Patient Outcomes Research Trial (SPORT) was a five-year study consisting of approximately 2500 patients with back and spine conditions. Participants entered qualitative data into an online portal, including post-surgical results and patient outcomes, to provide a comprehensive insight into treatment methods and their efficacy. Today, others suffering with those same conditions can enter their personal information into an online calculator and receive a prospective treatment plan. Together, patients and their doctors can view results and build a customized plan using more informed decisions about the available treatment options.

Another example comes from OpenNotes– an exploratory study that provides patients with full access to their medical files and the opportunity to input comments about their doctor visits and prognosis and make corrections related to the care they received. Results showed that this process helped patients retain a better understanding of their condition which improved their decision making and resulted in increased adherence to treatment plan protocols because they had greater trust with their doctors.Not only will this improve the patient experience by providing a safer, more sustainable treatment option, it also provides a very significant financial opportunity.

I believe the cannabis industry can take a leadership role in empowering patients to become active participants in their own treatment, while also sharing knowledge with the larger patient and physician communities. In fact, this core belief was the reason I founded Resolve Digital Health. Data-empowered patients not only make better decisions but also enjoy a greater feeling of control over their treatment. The power of collaborative healthcare grows exponentially when the data is shared to educate a broader group. By harnessing the power of the community, we can apply learnings from one patient’s cannabis use to help countless others.

Businesses within the cannabis industry can also leverage this data to create new products and services. For example, insights as to what products work best for certain conditions can help LP’s improve their product offerings and guide recommendations from dispensaries. Through product innovation, companies can make cannabis more accessible to a larger group of patients, who may be currently taking pharmaceuticals. Not only will this improve the patient experience by providing a safer, more sustainable treatment option, it also provides a very significant financial opportunity.

Ultimately, knowledge is power. When patients are empowered to make educated decisions about their health care and doctors are more tuned into the patient-tested cannabis treatment options, it’s a win-win for everyone.
