Enforcement of Intellectual Property Rights for Cannabis Put to Test in Federal Court

By Dr. Travis Bliss
No Comments

A number of cannabis businesses have pursued federal intellectual property protection for their cannabis-related innovations, such as U.S. patents that protect novel cannabis plant varieties, growing methods, extraction methods, etc. Enforcement of such federal IP rights requires that the IP owner file suit in federal court asserting those rights against another cannabis company. However, given that cannabis is still illegal under federal law, the industry is uncertain about whether a federal court will actually enforce cannabis-related IP rights. This question might be answered soon.

The potential impact of this case goes way beyond the two parties involvedOrochem Technologies, Inc. filed a lawsuit in federal court in the Northern District of Illinois on September 27, 2017, seeking to assert and enforce trade secret rights against Whole Hemp Company, LLC. According to the complaint, Orochem is a biotechnology company that uses proprietary separation methods to extract and purify cannabidiol (CBD) from industrial hemp in a way that produces a solvent-free and THC-free CBD product in commercially viable quantities.

The complaint goes on to say that Whole Hemp Company, which does business as Folium Biosciences, is a producer of CBD from industrial hemp and that Folium engaged Orochem to produce a THC-free CBD product for it. According to the allegations in the complaint, Folium used that engagement to gain access to and discover the details of Orochem’s trade secret method of extracting CBD so that it could take the process and use it at their facility.

The complaint provides a detailed story of the events that allegedly transpired, which eventually led to an Orochem employee with knowledge of the Orochem process leaving and secretly starting to work for Folium, where he allegedly helped Folium establish a CBD production line that uses Orochem’s trade secret process. When Orochem learned of these alleged transgressions, it filed the lawsuit, claiming that Folium (and the specific employee) had misappropriated its trade secret processes for extracting and purifying CBD.

While the particular facts of this case are both interesting and instructive for companies operating in the cannabis industry, the potential impact of this case goes way beyond the two parties involved.

If it moves forward, this case will likely provide a first glimpse into the willingness of federal courts to enforce IP rights that relate to cannabis. Orochem is asserting a violation of federal IP rights established under the federal Defend Trade Secrets Act (DTSA) and is asserting those rights in federal district court. As a result, the federal district court judge will first need to decide whether a federal court can enforce federal IP rights when the underlying intellectual property relates to cannabis.

If the court ultimately enforces these federal trade secret rights, it could be a strong indication that other federal IP rights, such as patent rights, would also be enforceable in federal court. Since the outcome of this case will likely have a far reaching and long lasting impact on how the cannabis industry approaches and deals with intellectual property, it’s a case worth watching.

PA Approves First Two Cannabis Labs

According to a PennLive article, Pennsylvania’s Department of Health approved the first two cannabis laboratories for their medical cannabis program. ACT Laboratories of Pennsylvania LLC and Keystone State Testing LLC are the companies that were approved to perform analytical testing for safety and quality in cannabis products.

Both laboratories expect to be operational before the end of 2017, according to the PennLive article. Those labs are required to test for CBD and THC content, pesticides, moisture content, residual solvents and microbiological contaminants.

The temporary lab testing regulations are somewhat comprehensive, detailing lab reporting, licensing, sampling protocols and ownership stipulations, among other rules. ACT and Keystone, the labs that were approved by the Department of Health, have their approval for two years and can renew their license after.

While the state still expects the program to be fully implemented by 2018, Health Secretary and Physician General Dr. Rachel Levine said last week they are hoping to launch the program sometime next year, according to a press release. December 2017 will mark a full year since the state opened applications for licensing businesses.

January 2018 has long been the goal for the full implementation of the program. “We have made significant progress in getting this program off the ground since Governor Wolf signed the Medical Marijuana Act into law last year,” says Dr. Levine. “These proposed regulations for patients and caregivers to participate are one of the final pieces we need to have in place to launch the program sometime next year.”

What’s Happening on Capitol Hill? Part 3: The Medical Bills

By Brian Blumenfeld, J.D., M.A.

This article continues the bill-by-bill review begun in the August 1st article on cannabis reform legislation proposed in the 115th Congress. In the next article and final piece in this series, we will examine the banking and tax reform bills related to cannabis.

Medical Cannabis Reform Bills 

S. 1008 – Therapeutic Hemp Medical Act of 2017

HR. 2273 – Charlotte’s Web Medical Access Act of 2017

Policy: These bills would amend the CSA to end federal prohibition over all CBD products and all hemp plants with THC content levels of below 0.3%. In other words, people and businesses would be free to grow hemp and/or manufacture CBD products without any fear of federal prosecution. These products would most likely then fall under the regulation of other federal and/or state agencies, but the bills do not specify what agencies they might be or what controls might be put in place.

Impact: The impacts from these bills nationwide have the potential to be massive. Hemp is a plant that can be put to highly effective use in many different industries, from textiles and construction to foodstuffs and seafaring. The efficiency of its growth and the breadth of its utility will make it a highly valuable commodity and a competitor with many other raw materials. For state-legal cannabis businesses, the legalization of CBD and hemp at the federal level could fundamentally change the market for those products. States that legalized cannabis already have provisions in place dealing with hemp and CBD—sometimes alongside their cannabis laws, sometimes handled by a separate state agency—and they could either leave those as they are or open up those markets to interstate activity. In states that have not legalized, CBD and hemp are typically included in the state’s definition of cannabis, and therefore they will remain illegal under state law unless further action is taken. Most likely, if federal prohibition ends on hemp and CBD, state prohibition will follow suit. Because legalization at the federal level will allow for interstate commerce in hemp and CBD, expect the emergence of a nationwide market, driven by online sales and interstate marketing, and developing independently from a cannabis industry still constrained to in-state activities.

S. 1008

  • Introduced: May 2, 2017 by Senator Cory Gardner (R-CO)
  • Cosponsors: 7 Republican, 4 Democrat
  • Referred to Senate Committee on:
    • Judiciary

 HR. 2273

  • Introduced: May 1, 2017 by Representative Scott Perry (R-PA)
  • Cosponsors: 10 Republicans, 10 Democrats
  • Referred to House Committee on:

      • Subcommittee on Crime, Terrorism, Homeland Security, and Investigations
    • Energy and Commerce
      • Subcommittee on Health
    • Financial Services

S. 1276 – Cannabidiol Research Expansion Act

Policy: This bill would accomplish two objectives: First, it would open channels for researchers to access and experiment with cannabis and cannabis extracts. Second, it would initiate the process at the end of which the Attorney General must make a determination as to which Schedule of the CSA is most appropriate for cannabidiol (CBD).

Impact: The impact on this legislation to state-legal cannabis businesses is rather remote—in both time and practice. The research access provisions will certainly create an uptick in medical and psychological research activity, the outcomes of which will add to our knowledge of how consuming cannabis in different forms and amounts effects the brain and body. This type of government-regulated research takes many years to process and complete, as both bureaucratic and scientific standards must be met. As for initiating the re/de-scheduling review process for CBD, this is a direct response to the 2016 denial by the DEA to re/de-schedule cannabis. That determination, published in the Federal Registrar on August 12, 2016, was made following a comprehensive study of the medical benefits and harms of cannabis conducted by the Department of Health and Human Services (HHS) and the Food and Drug Administration (FDA). Although such an in-depth study and its resulting negative determination pronounced so recently would normally rule out the chances of success for another re/de-scheduling attempt so soon after, the DEA did leave the door open with its statement that it “did not focus its evaluation on particular strains of marijuana or components or derivatives of marijuana.” It is just this door that S. 1276 seeks to exploit. By focusing the re/de-scheduling process on CBD specifically, the presumption is that the outcome of the scientific CBD studies would have a far better chance at satisfying the re/de-scheduling criteria set forth in the CSA. If such a determination was made, then the impact would come in two potential varieties. One, CBD would be rescheduled and become available for medical use according to FDA rules applicable to other prescription drugs. Two, CBD would be descheduled and would fall under the prerogative of the states, in which case the above analysis for S. 1008 and HR. 2273 would pertain.

  • Cosponsors: 3 Republican, 2 Democrat
  • Referred to Senate Committee on:
    • Judiciary

S. 1374 – Compassionate Access, Research Expansion, and Respect States (CARERS) Act of 2017

HR. 2920 – Compassionate Access, Research Expansion, and Respect States (CARERS) Act of 2017

HR. 715 – Compassionate Access Act of 2017

HR. 714 – Legitimate Use of Medical Marijuana Act (LUMMA) of 2017

Policy: All four of these bills would make an exception to the CSA for state medical cannabis laws. Federal prohibition, in other words, would end for medical cannabis in those states that have legalized, and it would be left to those states to devise how it would be regulated. In states that have not legalized, both state and federal prohibition would remain. The companion CARERS Acts in the House and Senate, along with HR. 714, would also amend FDA rules to widen access to cannabis for research purposes.

Impact: The impact of these bills on the rules for state-legal medical cannabis businesses would be relatively minor in terms of functionality. This is so because they leave not only the determination to legalize up to the states, but they leave the design of the regulatory system up to the states as well. In other areas, however, big changes will be seen that benefit the industry: banking will open up for state medical businesses, and so will the opportunity to write-off ordinary business expenses. Investment risks over legality will end, making for easier access to capital. Questions about contract enforcement and risks of federal prosecution will become moot, and when state regulatory bodies make decisions on how to govern the industry, they will no longer have to concern themselves with U.S. DOJ enforcement and/or prosecutorial policies. Enactment of any of these bills would be a big win for medical cannabis.

HR. 2020 – To Provide for the Rescheduling of Marijuana into Schedule III of the CSA

Policy: As its wordy title indicates, this bill would bypass the schedule review process and by legislative fiat move cannabis from Schedule I to Schedule III of the CSA.

Representative Matt Gaetz (R-FL)

Impact: Businesses handling drugs in Schedule III must register with the DEA and comply with DEA record keeping and security requirements. Doctors would be permitted to prescribe cannabis products. Importing/exporting will become available by permit, which would bring state businesses into competition with foreign cannabis firms. The biggest impact will be that cannabis sold pursuant to federal law will have to undergo the FDA’s New Drug Application process conducted by the Center for Drug Evaluation and Research, the largest of the FDA’s five centers. This includes clinical testing and a comprehensive chemical/pharmacological review. The drug would then be subject to FDA regulation for marketing and labelling. For states that wanted to maintain their legal medical cannabis systems, a conflict would remain because cannabis cultivators and dispensaries could operate in compliance with state law while simultaneously failing to meet new FDA and DEA requirements. States will then have a choice: bring state laws into line with federal laws, creating all of the advantages of federal legality discussed above, yet causing major disruptions to the industry; or retain the status quo, allowing the industry to grow as is with all of the in-state advantages but without the advantages of federal legalization. This all would of course leave behind recreational cannabis which would remain in the legal gray zone.

  • Cosponsors:
  • Referred to House Committee on:
    • Energy and Commerce
      • Subcommittee on Health
    • Judiciary

HR. 331 – States’ Medical Marijuana Property Right Protection Act

Policy: Section 881(a)(7) of the CSA subjects to federal forfeiture all property involved with cannabis activities. This bill would make an exception to that provision for all property in compliance with state medical cannabis laws.

Impact: Although not legalizing medical cannabis, this bill would be a strong step in the direction of legitimizing state-legal medical cannabis businesses. As a result of the property forfeiture clause of the CSA, two impediments faced by the medical cannabis industry is that investors are hesitant to invest and land lords are hesitant to lease or otherwise engage the medical cannabis market. By eliminating the risk of such property loss due to the federal-state conflict, this bill would have the very welcomed impact of easing access to capital and expanding opportunities for land use.

Cannabis-Infused Beer Goes Mainstream

By Aaron G. Biros
No Comments

Lagunitas Brewing today unveiled a new beer infused with cannabis, making it the first large national brewery to experiment with cannabis. Lagunitas, now owned by Heineken, announced the launch of their “Supercritical Ale,” an IPA brewed with terpenes extracted from cannabis.

The brewery chose to partner with AbsoluteXtracts and CannaCraft, based in California, for their cannabis extract and will use hops from Yakima, Washington. “We’ve long known about the close connection between cannabis and hops,” reads their website. “Now Lagunitas is excited to partner with a like-minded neighbor in Sonoma County, AbsoluteXtracts, to close the gap further with tandem innovations on the topic.” Hops and cannabis belong in the same taxonomic family, Cannabinaceae, and they also have a number of physical similarities, which helps explain the “close connection” they are referring to. The website says the beer will only be available in California—for now. According to Fortune Magazine, the terpenes come from two strains, Blue Dream and Girl Scout Cookies (known as GSC in some states).

The name “Supercritical” comes from the state that carbon dioxide is best used as a solvent for extracting compounds from plants. Terpenes are responsible for the aromatic properties of plants, giving hops the piney and citrusy flavors that come in IPAs, and giving cannabis the same flavors and smells as well. Limonene, for example, is a cyclic terpene molecule that gives us a citrusy smell and flavor.

Coalition brewing Co.’s Two Flowers IPA

They’re not the first brewery to experiment with cannabis-infused beer; smaller craft breweries have been doing it for some time now. Coalition Brewing Co., based in Portland, Oregon, sells a cannabis-infused beer called Two Flowers IPA, with 3mg of cannabidiol (CBD) in a 12oz glass. Dad and Dudes Breweria, based in Aurora, Colorado, also put out a CBD-infused beer last year, called General Washington’s Secret Stash. According to Westword, Dad and Dudes was the first brewery to receive federal approval for a CBD-infused beer, but since the DEA declared cannabis oil illegal last winter, the Alcohol and Tobacco Tax and Trade Bureau rescinded their approval.

The common denominator between these three beers is that none of them contain THC, the popular psychoactive ingredient in cannabis. Perhaps Lagunitas is taking a safer approach with regard to federal legality by only using terpenes, not CBD, and only offering it in state. Coalition’s Two Flowers IPA is also only available in Oregon, but does, however, contain CBD. Check out the video on Lagunitas’ Supercritical Ale below.

Clear vs. Pure: How Fallacies and Ignorance of Extraction Misrepresent the Cannabis Flower

By Dr. Markus Roggen
14 Comments

Demand for cannabis extracts, in particular vaping products, is at an all-time high. People want good oil, and they want to know something about the quality of it. It is therefore time to take a step back and consider the process from plant to cartridge. What is the current industry standard for cannabis extraction, what constitutes quality and where might we need to make some adjustments?

Right now, “clear” oil is hot. Customers have been led to believe that a pale gold extract is synonymous with the best possible cannabis concentrate, which is not necessarily the case. Producing a 95% pure THC extract with a translucent appearance is neither a great scientific feat nor a good representation of the whole cannabis flower. Moreover, it runs counter to the current trend of all-natural, non-processed foods and wellness products.

“My carrots are organic and fresh from the farmers market, my drink has no artificial sweeteners and my honey is raw, but my cannabis oil has undergone a dozen steps to look clear and still contains butane.”Cannabis is a fascinating plant. It is the basis of our livelihood, but more importantly, it enhances the quality of life for patients. The cannabis plant offers a plethora of medicinally interesting compounds. THC, CBD and terpenes are the most popular, but there are so many more. As of the most recent count, there are 146 known cannabinoids1. Cannabinoids are a group of structurally similar molecules2, including THC and CBD, many of which have shown biological activity3.

Then there are terpenes. These are the smaller molecules that give cannabis its distinct smell and flavor, over 200 of which have been identified in cannabis4. But wait, there’s more. The cannabis plant also produces countless other metabolites: flavonoids, alkaloids, phenols and amides5. All these components mixed together give the often-cited entourage effect6,7.

Current industry standards for cannabis oil extraction and purification stand in marked contrast to the complexity of the plant’s components. Due to an unsophisticated understanding of the extraction process and its underlying chemistry, cannabis oil manufacturers frequently produce oil of low quality with high levels of contamination. This necessitates further purifications and clean up steps that remove such contaminants unfortunately along with beneficial minor plant compounds. If one purifies an extract to a clear THC oil, one cannot also offer the full spectrum of cannabinoids, terpenes and other components. Additionally, claiming purities around 95% THC and being proud of it, makes any self-respecting organic chemist cringe8.

Precise control of extraction conditions leads to variable, customized concentrates. THC-A crumble, terpene-rich vape oil, THC sap (from left to right).

The labor-intensive, multi-step extraction process is also contrary to “the clean-label food trend”, which “has gone fully mainstream”9. Exposing the cannabis flower and oil to at least half a dozen processing steps violates consumer’s desire for clean medicine. Furthermore, the current practice of calling supercritical-CO2-extracted oils solvent-less violates basic scientific principles. Firstly, CO2 is used as a solvent, and secondly, if ethanol is used to winterize10, this would introduce another solvent to the cannabis oil.

We should reconsider our current extraction practices. We can offer cannabis extracts that are free of harmful solvents and pesticides, give a better, if not full, representation of the cannabis plant and meet the patients’ desire for clean medicine. Realizing extracts as the growth-driver they are11 will make us use better, fresher starting materials12. Understanding the underlying science and learning about the extraction processes will allow us to fine-tune the process to the point that we target extract customized cannabis concentrates13. Those, in turn, will not require additional multi-step purification processes, that destroys the basis of the entourage effect.

The cannabis industry needs to invest and educate. Better extracts are the result of knowledgeable, skilled people using precise instruments. Backroom extraction with a PVC pipe and a lighter should be horror stories of the past. And only when the patient knows how their medicine is made can they make educated choices. Through knowledge, patients will understand why quality has its price.

In short, over-processing to make clear oil violates both the plant’s complexity and consumers’ desires. Let us strive for pure extracts, not clear. Our patients deserve it.

Protecting Your Innovative Cannabis Strains With a Strong Intellectual Property Strategy: Part 2 – Patents for New Cannabis Strains

By Dr. Travis Bliss
No Comments

In the first installment of this three-part series we explored the reasons why cannabis breeders should adopt a strong IP strategy sooner rather than later and looked briefly at the types of IP that those breeders and growers should be considering. In this second installment, we will examine in more detail patent protection for innovative new varieties of cannabis and how one can use that patent protection to further their business objectives.

What is a patent and what do I do with one?

A patent is a right granted by the government to protect a new and useful invention. Importantly, a patent gives its owner an exclusionary right as opposed to a right to do something – the patent owner has the right to exclude others from making, using, selling, offering to sell, or importing the invention (or, for a plant, any of its plant parts) for the term of the patent, which is 20 years for the types of patents that can be used to protect new cannabis varieties.

Because it is an exclusionary right, there are essentially two things that a patent owner can use a patent to do: 1) disallow anyone else from producing and selling that variety (or any of its parts) so that the patent owner is able to capture all of the sales for that variety, or 2) use license contracts to allow other growers to grow the variety while paying royalties back to the patent holder. The latter option can often be beneficial because it can greatly expand production of the variety by licensing to multiple growers. However, this does require some oversight on the part of the patent holder to make sure that the product those growers are producing is high quality –growers who produce poor quality product can hurt the existing brand. Cannabis breeders should consider these options up front when formulating their IP strategy.

Which type of patent should I use to protect my new variety?

As a further consideration, there are two different types of patents that can be used to protect new plant varieties and there are multiple factors to consider when determining which one to pursue.

U.S. Plant Patents are a special type of intellectual property that is used solely for the protection of asexually/vegetatively reproduced plant varieties. Traditionally, plant patents have been used to protect new varieties of ornamental and fruit trees and shrubs, such as a new variety of rose bush or a new variety of apple tree, such as the ‘Honeycrisp’ apple tree, patented in 1990. This type of patent has recently been used to protect a new cannabis variety called ‘Ecuadorian sativa’, while several other cannabis varieties, ‘Midnight’, ‘Erez’, and ‘Avidekel’ varieties are awaiting plant patent approval.

On the other hand, a “utility patent” can be used for new “compositions” (e.g., a new type of grow light) or new types of “methods” (e.g., a new method of extracting compounds from cannabis or a new method of growing cannabis to produce higher THC content). This type of patent can also be used to protect a new plant variety so long as the applicant can demonstrate that the variety is novel and not obvious over what was already known in the art. To date, two utility patents have been issued to protect cannabis varieties that exhibit certain cannabinoid and terpene profiles (U.S. Patent Nos. 9,095,554 and 9,370,164), and other similar utility patent applications are also pending (e.g., U.S. Patent Pub. No. 2014/0298511).

One of the main determining factors in deciding which type of patent to pursue is the nature of the invention. Growers and breeders will likely want to seek a plant patent if they have developed a new variety of cannabis plant: 1) which was made using simple breeding techniques, 2) which can be stably reproduced in an asexual manner (such as by cuttings and cloning), and 3) which is different from its parents and certain other strains on the market, but not completely distinct from everything that already exists. On the other hand, growers and breeders may want to consider a utility patent if they have developed a new variety of cannabis plant: 1) which has unique features in comparison to everything else that exists today (such as a unique disease resistance or chemical makeup), 2) which has unique features that can be demonstrated by some sort of biological or chemical test, and 3) that can be reproduced either asexually or by seed. It is also important to keep in mind that these two routes are not mutually exclusive – one could apply for both types of patent if the variety satisfies the criteria for both.

Though there are numerous similarities between the processes for obtaining both types of patents, there are also clear differences that should be taken into consideration when making the decision about which type of patent to seek. For instance, the grant rate for plant patents is much higher, meaning there is a higher likelihood that the plant patent application will eventually be granted compared to a utility patent application. Further, plant patent applications typically move quicker through the Patent Office, frequently being granted in approximately 18 months, while utility patent applications typically take two to four years (or more) to issue.

Another factor that should be considered is cost. Because a plant patent application is much simpler to prepare and typically moves through the Patent Office more swiftly, the cost for obtaining a plant patent is generally significantly lower than for a utility patent.

Determining which type of patent to pursue requires consideration of numerous factors. However, it is important to keep in mind that, regardless of which type of patent a grower or breeder seeks, there are certain time limitations that can impact the right to obtain a patent. For example, patent protection can only be sought if the variety to be patented has not been sold, offered for sale, or otherwise made publicly available more than one year before the patent application is filed. After that time, the invention becomes part of the “public domain.” So if a breeder chooses to wait to seek patent protection for a new variety, they risk losing the ability to ever get that protection.

Clearly, growers and breeders have to weigh several options when formulating a patent strategy, including what type of patent to pursue and what to do with the patent once they obtain it. Thinking through these issues early on allows the cannabis breeder an opportunity to formulate a strategy that is most beneficial in furthering their business objectives. Additionally, regardless of the type of patent strategy used, it is often helpful to combine it with trademark and branding strategy, which allows the business to utilize a more comprehensive approach to IP for their innovative strains. The third installment of this series will focus on trademarks for cannabis products and some unique issues that facing the cannabis industry today.

Israeli Cannabis Brand Tikun Olam Expands to US

By Aaron G. Biros
2 Comments

Tikun Olam is a Jewish concept that addresses social policy, promoting acts of kindness to better society. In Hebrew, it literally means, “repair of the world.” The company by the same name, Tikun Olam Ltd, and now in the United States as T.O. Global LLC, was the first medical cannabis provider in Israel back in 2007. Working with patients, doctors and nurses in clinical trials, they developed 16 strains over the last decade that target alleviating symptoms of specific ailments.

Tel Aviv, Israel, where Tikun Olam has a dispensary

In November 2016, they launched their United States brand, Tikun, in the Delaware medical cannabis program with their partner, First State Compassion Center, a vertically integrated business of cultivation, extraction and retail in Wilmington. After the success of their pilot program, Tikun announced their expansion into the Nevada market with their licensed partner, CW Nevada LLC. Tikun is leveraging its experience with clinical trials and medical research to launch a line of cannabis products focused on health and wellness in the United States. According to Stephan Gardner, chief marketing officer at Tikun Olam, they have the largest collection of medical cannabis data in the world. “Tikun Olam started out as a non-profit, working to bring medication to patients in Israel,” says Gardner. “Opening nursing clinics gave us a tremendous amount of knowledge and data to work on the efficacy of strains developed specifically for targeting symptoms associated with certain conditions.” For example, their strain, Avidekel, was developed years ago as the first high-CBD strain ever created.

The strain Avidekel being grown in Israel.

In a single-strain extraction, Avidekel has been used to successfully mitigate the symptoms associated with neurological conditions, like epilepsy in children, and they have the data to demonstrate that efficacy. “The American market needs some sort of guidance on how these cannabinoid and terpene profiles in certain strains can truly assist patients,” says Gardner. “We have been tracking and monitoring our patients with clinical and observational data in one, six month and annual follow ups, which are data we can use to guide the needs in the US.”

Their expansion strategy focuses heavily on the health benefits of their strains, not necessarily targeting the recreational market. “As a wellness brand in Nevada, we are positioned to work first and foremost in the medical market,” says Gardner. “Our wellness brand can cater to people looking for homeopathic remedies for things like inflammation issues, sleep disorders or pain relief for example,” says Gardner. “You will not see us going out there catering to the truly recreational market; the benefits of what our strains can do is marketed from a wellness perspective.” A cannabis product with high-THC percentages is not unique, says Gardner, but their approach using the entourage effect and proven delivery mechanisms is. “While higher THC might appeal to the rec market, that is not exactly how we will promote and position ourselves,” says Gardner. “We want to be a dominant force in the wellness market.”

Best practices include quality control protocols

That effort requires working within the US regulatory framework, which can be quite complicated compared to their experience in Israel. “We have to understand the Israeli market and American market are completely different due to the regulatory regimes each country has in place,” says Gardner. “We understand the efficacy of these products and want to educate customers on how they might benefit. We don’t want to make claims looking to cure anything, but we found in our data that a lot of symptoms in different ailments, like cancer, PTSD, Crohn’s disease, colitis and IBS, can be alleviated by strains we developed.” In addition to the medical research, they are bringing their intellectual property, cultivation methodologies, evidence-based scientific collaboration and best practices to their partners in the US.

So for Tikun’s expansion in the US, they want to get a medical dialogue going. “We will launch a fully accredited AMA [American Medical Association] program, educating medical practitioners, giving the doctors the understanding of the capabilities of cannabis and what our strains can do,” says Gardner. “We will also share our observational data with doctors so they can work to better guide their patients.” Right now, they are working on the education platform in their pilot program in Delaware. “We plan on using that as a platform to expand into other markets like Nevada,” says Gardner. “And we will be launching the Tikun brand in the Washington market this summer.” Based on the high demand they saw in the Delaware market, Gardner says they plan to launch six unique strains in the American market, with delivery mechanisms like vape products, tinctures, lozenges and topicals in addition to dried flower.

While Tikun expands throughout the United States, their sights are set on global expansion, living up to the true meaning of the concept Tikun Olam. They entered a strategic partnership with a licensed producer based in Toronto, bringing their strains, including Avidekel, to the Canadian market. The company they are partnering with, MedReleaf, recently filed for an initial public offering (IPO) on the Toronto stock exchange. Tikun Olam is actively seeking to expand in other parts of the world as well.

On Monday, March 6th, Shimadzu Scientific Instruments, a leading laboratory analytical instrumentation manufacturer, announced the launch of a new product focused on cannabis, according to a press release. Their Cannabis Analyzer for Potency is essentially a high-performance liquid chromatograph (HPLC) packaged with integrated hardware, software, workflows and all the supplies. The supplies include an analytical column, guard columns, mobile phase and a CRM standard mixture.canAnalyzerImg1

The instrument is designed to test for 11 cannabinoids in less time and with greater ease than traditional HPLC instruments. In the press release, they claim “operators are now able to produce accurate results with ease, regardless of cannabis testing knowledge or chromatography experience.” One very unique aspect of the instrument is the lack of experience required to run it, according to Bob Clifford, general manager of marketing at Shimadzu. “We have our typical chromatography software [LabSolutions] with an overlay that allows the user to analyze a sample in three simple steps,” says Clifford. Those in the cannabis industry that have a background in plant science, but not analytical chemistry, could run potency analyses on the instrument with minimal training. “This overlay allows ease of use for those not familiar with chromatography software,” says Clifford.

The instrument can determine cannabinoid percentages per dry weight in flower concentrates and edibles. “Once you open the software, it will get the flow rate started, heat the column up and automatically begin to prep for analysis,” says Clifford. Before the analysis begins, information like the sample ID number, sample name, sample weight, extraction volume and dilution volume are entered. After the analysis is complete all the test results are reported for each sample.

Because laboratories wouldn’t have to develop quantitative testing methodology, they argue this instrument would save a lot of time in the lab. “After one day of installation and testing, users are equipped with everything they need to obtain cannabis potency results,” states the press release. According to Clifford, method development for potency analysis in-house can take some labs up to three months. “We can bring this instrument to the lab and have it ready for testing almost immediately,” says Clifford. “The methods for this instrument were developed by a team of twenty scientists working on different platforms at our Innovation Center and was tested for ruggedness, repeatability and quantitative accuracy.”

The instrument’s workflow is designed to meet three methods of analysis depending on testing needs. The High Throughput method package can determine quantities of ten cannabinoids with less than eight minutes per sample. The method was developed in collaboration with commercial testing laboratories. The High Sensitivity method package adds THCV to that target analyte list with ten minutes per analysis. The method provides the sharpest chromatographic peaks and best sensitivity. The High Resolution method package offers full baseline resolution for those 11 cannabinoids in less than 30 minutes per analysis and the ability to add cannabinoids to that target list if regulations change.

The press release states the interface should allow users to reduce the number of steps needed in the analysis and simplify the workflow. The instrument comes with a three-year warranty, preventative maintenance plan and lifetime technical support.

Hoban Law Group Files Lawsuit Against DEA

By Aaron G. Biros

The Hoban Law Group filed a petition on behalf of three clients against the DEA in the U.S. Court of Appeals for the Ninth District on January 13th, according to a press release. The clients represented by Hoban Law Group in the suit are Hemp Industries Association, RMH Holdings, LLC and Centuria Natural Foods, Inc. The companies are based in California, Colorado and Nevada respectively and are all active in the legal hemp trade. The press release says RMH Holdings “sources its products from industrial hemp lawfully cultivated pursuant to the Agricultural Act of 2014 (also known as the Farm Bill).”

In December, the DEA published a ‘Final Rule’ that classifies cannabis-derived extracts, such as CBD oil, in their own category with a code number to “better track these materials and comply with treaty provisions.” The announcement by the DEA ultimately serves to make any cannabis extract a Schedule 1 narcotic. “Extracts of marihuana will continue to be treated as Schedule I controlled substances,” says the document.

Bob Hoban, managing partner of Hoban Law Group says the action is clearly beyond the DEA’s authority. “This Final Rule serves to threaten hundreds, if not thousands, of growing businesses, with massive economic and industry expansion opportunities, all of which conduct lawful business compliant with existing policy as it is understood and in reliance upon the Federal Government,” says Hoban.

The lawsuit states that they want a judicial review of the DEA’s actions “on the grounds that the Final Rule is (1) arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law, e.g. the CSA, the Farm Bill, and the DEA’s regulations; (2) contrary to constitutional right, power, privilege, or immunity; (3) in excess of statutory jurisdiction, authority, or limitations; and, (4) without observance of procedure required by law.” The suit also claims that the ‘Final Rule’ conflicts with other federal laws like the Data Quality Act, Regulatory Flexibility Act and Congressional Review Act.

According to Garrett Graff, associate attorney at Hoban Law Group, the entire Cannabis genus is not unlawful and the DEA is overstepping its authority. “As the Ninth Circuit found in 2003 and 2004 there are certain parts of the plant like the stalk and seed that are congressionally exempted from the Controlled Substances Act and thus the DEA’s rulemaking authority,” says Graff. “By creating a drug code for ‘marihuana extract’, the DEA is saying that they are a controlled substance, but that goes against a number of existing laws.”

The definition of ‘marihuana extract’ under the ‘Final Rule’ also references extracts containing one or more cannabinoids, which goes beyond the realm of cannabis altogether, according to Graff. “The DEA and many other sources have acknowledged and confirmed that cannabinoids can be derived from other varieties of flowers, cacao and other sources, making it virtually impossible to distinguish which cannabinoids would be subject to this drug code,” says Graff. “The DEA’s rule effectively makes the presence of cannabinoids a determinative factor of a controlled substance, which is inconsistent with what Congress has said.”

The petition filed is essentially the initiation or commencing of a lawsuit. Graff says their case is rooted in statute. “We hope to accomplish a striking of the rule, permanent injunction of the rule and for the DEA to engage in the appropriate processes and procedures when making rules in the future,” says Graff. “Alternatively, an amendment to the rule to make the definition of ‘marihuana extract’ consistent with existing law and reflect those portions and varieties of the plant which are in fact lawful could be considered.” It may still be roughly 30 days before the DEA responds with briefing and possibly an oral argument to follow on the various issues surrounding the petition, says Graff. The Ninth Circuit petition, including briefings and hearings, is likely to take at least several months.

Potency Analysis of Cannabis and Derivative Products: Part 2

By Rebecca Stevens
2 Comments

As mentioned in Part 1, the physiological effects of cannabis are mediated by a group of structurally related organic compounds known as cannabinoids. The cannabinoids are biosynthetically produced by a growing cannabis plant and Figure 1 details the biosynthetic pathways leading to some of the most important cannabinoids in plant material.

The analytical measurement of cannabinoids is important to ensure the safety and quality of cannabis as well as its extracts and edible formulations. Total cannabinoid levels can vary significantly between different cultivars and batches, from about 5% up to 20% or more by dry weight. Information on cannabinoid profiles can be used to tailor cultivars for specific effects and allows end users to select an appropriate dose.

Routine Analysis vs. Cannabinomics 

Several structurally analogous groups of cannabinoids exist. In total, structures have been assigned for more than 70 unique phytocannabinoids as of 2005 and the burgeoning field of cannabinomics seeks to comprehensively measure these compounds.¹

Considering practical potency analysis, the vast majority of cannabinoid content is accounted for by 10-12 compounds. These include Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabigerol (CBG), Δ9-tetrahydrocannabivarian (THCV), cannabidivarin (CBDV) and their respective carboxylic acid forms. The cannabinoids occur primarily as carboxylic acids in plant material. Decarboxylation occurs when heat is applied through smoking, vaporization or cooking thereby producing neutral cannabinoids which are more physiologically active.

Potency Analysis by HPLC and GC

Currently, HPLC and GC are the two most commonly used techniques for potency analysis. In the case of GC, the heat used to vaporize the injected sample causes decarboxylation of the native cannabinoid acids. Derivatization of the acids may help reduce decarboxylation but overall this adds another layer of complexity to the analysis² ³. HPLC is the method of choice for direct analysis of cannabinoid profiles and this technique will be discussed further.

A sample preparation method consisting of grinding/homogenization and alcohol extraction is commonly used for cannabis flower and extracts. It has been shown to provide good recovery and precision² ³. An aliquot of the resulting extract can then be diluted with an HPLC compatible solvent such as 25% water / 75% acetonitrile with 0.1% formic acid. The cannabinoids are not particularly water soluble and can precipitate if the aqueous percentage is too high.

To avoid peak distortion and shifting retention times the diluent and initial mobile phase composition should be reasonably well matched. Another approach is to make a smaller injection (1-2 µL) of a more dissimilar solvent. The addition of formic acid or ammonium formate buffer acidifies the mobile phase and keeps the cannabinoid acids protonated.

The protonated acids are neutral and thus well retained on a C18 type column, even at higher (~50% or greater) concentrations of organic solvent² ³.

Detection is most often done using UV absorbance. Two main types of UV detectors are available for HPLC, single wavelength and diode array. A diode array detector (DAD) measures absorbance across a range of wavelengths producing a spectrum at each point in a chromatogram while single wavelength detectors only monitor absorbance at a single user selected wavelength. The DAD is more expensive, but very useful for detecting coelutions and interferences.
