Yesterday, the Colorado Marijuana Enforcement Division issued a bulletin unveiling their universal symbol for all cannabis products. According to the bulletin, the State Licensing Authority adopts the universal symbol for all packaging, labeling and on-product marking for medical and recreational cannabis products, effective immediately.
“The State Licensing Authority’s adoption of a Single Universal Symbol is intended to further protect public health and safety by enhancing consumers’ ability to identify products containing marijuana,” reads the bulletin, signed by James Burack, director of the Marijuana Enforcement Division. “Further, by eliminating distinctions between Universal Symbols for medical and retail marijuana, the Single Universal Symbol works to simplify and improve compliance regarding packaging, labeling, and product marking requirements.”
On January 1st, 2019, use of the universal symbol on packaging will be mandatory for all products, with a few exceptions for medical center sales with existing inventory. There is an optional use period that lasts until the end of 2018 where producers and retailers can use the previous universal symbols. After July 1st, 2019, every product sold in the state of Colorado must have the updated universal symbols, according to the bulletin.
On packaging and labeling, the red and white symbol is required whereas on single servings, the symbol must be on one side but doesn’t need to have the colors.

With legalization of cannabis for medicinal and adult use occurring rapidly at the state level, the industry is seeing a sharp increase in innovative technologies, particularly in the area of cannabis extraction. Companies are developing novel extraction methods that are capable of not only separating and recovering high yields of specific cannabinoids, but also removing harmful chemicals (such as pesticides) from the concentrate. While some extraction methods utilize solvents, such as hydrocarbons, the industry is starting to see a shift to completely non-solvent based techniques or environmentally friendly solvents that rely on, for example, CO2, heat and pressure to create a concentrate. The resulting cannabis concentrate can then be consumed directly, or infused in edibles, vape pens, topicals and other non-plant based consumption products. With companies continually seeking to improve existing extraction equipment, methods and products, it is critical for companies working in this area to secure their niche in the industry by protecting their intellectual property (IP).
Comprehensive IP protection for a business can include obtaining patents for innovations, trademarks to establish brand protection of goods and services, copyrights to protect logos and original works, trade dress to protect product packaging, as well as a combination of trade secret and confidentiality agreements to protect proprietary information and company “know-how” from leaking into the hands of competitors. IP protection in the cannabis space presents unique challenges due to conflicting state and federal law, but for the most part is available to cannabis companies like any other company.
Federal trademark protection is currently one of the biggest challenges facing cannabis companies in the United States. A trademark or service mark is a word, phrase, symbol or design that distinguishes the source of goods or services of one company from another company. Registering a mark with the U.S. Patent and Trademark Office (USPTO) provides companies with nationwide protection against another company operating in the same space from also using the mark.
As many in the industry have come to discover, the USPTO currently will not grant a trademark or service mark on cannabis goods or services. According to the USPTO, since cannabis is illegal federally, marks on cannabis goods and services cannot satisfy the lawful use in commerce requirement of the Lanham Act, the statute governing federal trademark rights. Extraction companies that only manufacture cannabis-specific equipment or use cannabis-exclusive processes will likely be unable to obtain a federal trademark registration and will need to rely on state trademark registration, which provides protection only at the state-level. However, extractors may be able to obtain a federal trademark on their extraction machines and processes that can legitimately be applied to non-cannabis plants. Likewise, companies that sell cannabis-infused edibles may be able to obtain a federal trademark on a mark for non-cannabis containing edibles if that company has such a product line.
Some extraction companies may benefit from keeping their innovations a trade secretSince the USPTO will not grant marks on cannabis goods and services, a common misconception in the industry is that the USPTO will also not grant patents on cannabis inventions. But, in fact, the USPTO will grant patents on a seemingly endless range of new and nonobvious cannabis inventions, including the plant itself. (For more information on how breeders can patent their strains, see Alison J. Baldwin et al., Protecting Cannabis – Are Plant Patents Cool Now? Snippets, Vol. 15, Issue 4, Fall 2017, at 6). Unlike the Lanham Act, the patent statute does not prohibit illegal activity and states at 35 U.S.C. § 101 that a patent may be obtained for “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof.”
For inventions related to extraction equipment, extraction processes, infused products and even methods of treatment with concentrated formulations, utility patents are available to companies. Utility patents offer broad protection because all aspects related to cannabis extraction could potentially be described and claimed in the same patent. Indeed, there are already a number of granted patents and published patent applications related to cannabis extraction. Recently, U.S. Patent No. 9,730,911 (the ‘911 patent), entitled “Cannabis extracts and methods of preparing and using same” that granted to United Cannabis Corp. covers various liquid cannabinoid formulations containing very high concentrations of tetrahydrocannabinolic acid (THCa), tetrahydrocannabinol (THC), cannabidiol (CBD), THCa and cannabidiolic acid, THC and CBD, and CBD, cannabinol (CBN), and THC. For example, claim 1 of the ‘911 patent recites:
A liquid cannabinoid formulation, wherein at least 95% of the total cannabinoids is tetrahydrocannabinolic acid (THCa).Properly crafted non-disclosure agreements can help further ensure that trade secrets remain a secret indefinitely.
Although the ‘911 patent only covers the formulations, United Cannabis Corp. has filed a continuation application that published as US2017/0360745 on methods for relieving symptoms associated with a variety of illnesses by administering one or more of the cannabinoid formulations claimed in the ‘911 patent. This continuation application contains the exact same information as the ‘911 patent and is an example of how the same information can be used to seek complete protection of an invention via multiple patents.
An example of a patent application directed to solvent-based extraction methods and equipment is found in US20130079531, entitled “Process for the Rapid Extraction of Active Ingredients from Herbal Materials.” Claim 1 of the originally filed application recites:
A method for the extraction of active ingredients from herbal material comprising: (i) introducing the herbal material to a non-polar or mildly polar solvent at or below a temperature of 10 degrees centigrade and (ii) rapidly separating the herbal material from the solvent after a latency period not to exceed 15 minutes.
Claim 12, covered any equipment designed to utilize the process defined in claim 1.
Although now abandoned, the claims of this application were not necessarily limited to cannabis, as the claims were directed to extracting active ingredients from “herbal materials.”
Other patents involve non-toxic extraction methods utilizing CO2, such as Bionorica Ethics GMBH’s U.S. Patent No. 8,895,078, entitled “Method for producing an extract from cannabis plant matter, containing a tetrahydrocannabinol and a cannabidiol and cannabis extracts.” This patent covers processes for producing cannabidiol from a primary extract from industrial hemp plant material.
There have also been patents granted to cannabis-infused products, such as U.S. Patent No. 9,888,703, entitled “Method for making coffee products containing cannabis ingredients.” Claim 1 of this patent recites:
A coffee pod consisting essentially of carbon dioxide extracted THC oil from cannabis, coffee beans and maltodextrin.
Despite the USPTO’s willingness to grant cannabis patents, there is an open question currently regarding whether they can be enforced in a federal court (the only courts that have jurisdiction to hear patent cases). However, since utility patents have a 20-year term, extractors are still wise to seek patent protection of the innovations now.
Another consideration in seeking patent protection for novel extraction methods and formulations is that the information becomes public knowledge once the patent application publishes. As this space becomes increasingly crowded, the ability to obtain broader patents will decline. Therefore, some extraction companies may benefit from keeping their innovations a trade secret, which means that the secret is not known to the public, properly maintained and creates economic value by way of being a secret. Properly crafted non-disclosure agreements can help further ensure that trade secrets remain a secret indefinitely.
Regardless of the IP strategy extractors choose, IP protection should be a primary consideration for companies in the cannabis industry to ensure the strongest protection possible both now and in the future.
I have been studying microorganisms for over 35 years, and the elusive critters still fascinate me! Here in Microbiology 101, I write about the foundation of knowledge on which all microbiologists build. You may have a general interest in microbiology or have concerns in your operation. By understanding microbiology, you understand the diversity of microorganisms, their source, control of microorganisms and their importance.
The term microbiology covers every living being we cannot see with the naked eye. The smallest microbe is a virus. Next in size are the bacteria, then yeast and mold cells, and the largest microbes are the protozoans. The tiny structure of a virus may be important in the plant pathology of cannabis, but will not grow in concentrates or infused products. A virus is not living, until it storms the gate of a living cell and overtakes the functions within the cell. Viruses are the number one cause of foodborne illness, with the number one virus called Norovirus. Think stomach flu. Think illness on cruise ships. Viruses are a food service problem and can be prevented by requiring employees to report sickness, have good personal hygiene including good hand washing, and, as appropriate, wear gloves. Following Good Manufacturing Practices (GMPs) is critical in preventing the transfer of viruses to a product where the consumer can be infected.
The largest microbial cell is the protozoan. They are of concern in natural water sources, but like viruses, will not grow in cannabis products. Control water quality through GMPs, and you control protozoans. Viruses and protozoans will not be further discussed here. Bacteria, yeast and mold are the focus of further discussion. As a food microbiologist, my typical application of this information is in the manufacturing of food. Because Microbiology 101 is a general article on microbiology, you can apply the information to growing, harvesting, drying, manufacture of infused products and dispensing.
It is not possible to have sterile products. Even the canning process of high temperature for an extended time allows the survival of resistant bacterial spores. Astronauts take dehydrated food into space, and soldiers receive MREs; both still contain microbes. Sterility is never the goal. So, what is normal? Even with the highest standards, it is normal to have microbes in your products. Your goal is to eliminate illness-causing microorganisms, i.e. pathogens. Along the way, you will decrease spoilage microbes too, making a product with higher quality.
Yeast and mold were discussed on CIJ in a previous article, Total Yeast & Mold Count: What Cultivators & Business Owners Need to Know. Fuzzy mold seen on the top of food left in the refrigerator too long is a quality issue, not a safety issue. Mold growth is a problem on damaged cannabis plants or cuttings and may produce mycotoxin, a toxic chemical hazard. Following Good Agricultural Practices (GAPs) will control mold growth. Once the plant is properly dried, mold will not grow and produce toxin. Proper growing, handling and drying prevents mycotoxins. Like mold, growth of yeast is a quality issue, not a safety issue. As yeast grow, they produce acid, alcohol and carbon dioxide gas. While these fermentation products are unwanted, they are not injurious. I am aware that some states require cannabis-infused products to be alcohol-free, but that is not a safety issue discussed here.
What are the sources of microorganisms?
People. Employees who harvest cannabis may transfer microorganisms to the plant. Later, employees may be the source of microbes at the steps of trimming, drying, transfer or portioning, extract processing, infused product manufacture and packaging.
Ingredients, Supplies and Materials. Anything you purchase may be a source of microorganisms. Procure quality merchandise. Remember the saying, “you get what you pay for.”
Environment. Starting with the outdoors, microbes come from wind, soil, pests, bird droppings and water. When plants are harvested outdoors or indoors, microbes come from the tools and bins. Maintain clean growing and harvesting tools in good working condition to minimize contamination with microbes. For any processing, microbes come from air currents, use of water, and all surfaces in the processing environment from dripping overhead pipes to floor drains and everything in between.
In Part 2 I will continue to discuss the diversity of microorganisms, and future articles will cover Hazard Analysis and Critical Control Points (HACCP) and food safety in more detail. What concerns do you have at each step of operations? Are you confident in your employees and their handling of the product? As each state works to ensure public health, cannabis-infused products will receive the same, if not more, scrutiny as non-cannabis food and beverages. With an understanding and control of pathogens, you can focus on providing your customers with your highest quality product.
In late November, California released their proposed emergency regulations for the cannabis industry, ahead of the full 2018 medical and adult use legalization for the state. We highlighted some of the key takeaways from the California Bureau of Cannabis Control’s regulations for the entire industry earlier. Now, we are going to take a look at the California Department of Public Health (CDPH) cannabis manufacturing regulations.
According to the summary published by the CDPH, business can have an A-type license (for products sold on the adult use market) and an M-type license (products sold on the medical market). The four license types in extraction are as follows:
Type 7: Extraction using volatile solvents (butane, hexane, pentane)
Type 6: Extraction using a non-volatile solvent or mechanical method
(food-grade butter, oil, water, ethanol, or carbon dioxide)
Type N: Infusions (using pre-extracted oils to create edibles, beverages,
capsules, vape cartridges, tinctures or topicals)
Type P: Packaging and labeling only
As we discussed in out initial breakdown of the overall rules, California’s dual licensing system means applicants must get local approval before getting a state license to operate.
The rules dictate a close-loop system certified by a California-licensed engineer when using carbon dioxide or a volatile solvent in extraction. They require 99% purity for hydrocarbon solvents. Local fire code officials must certify all extraction facilities.
In the realm of edibles, much like the rule that Colorado recently implemented, infused products cannot be shaped like a human, animal, insect, or fruit. No more than 10mg of THC per serving and 100mg of THC per package is allowed in infused products, with the exception of tinctures, capsules or topicals that are limited to 1,000 mg of THC for the adult use market and 2,000 mg in the medical market. This is a rule very similar to what we have seen Washington, Oregon and Colorado implement.
On a somewhat interesting note, no cannabis infused products can contain nicotine, caffeine or alcohol. California already has brewers and winemakers using cannabis in beer and wine, so it will be interesting to see how this rule might change, if at all.
The rules for packaging and labeling are indicative of a major push for product safety, disclosure and differentiating cannabis products from other foods. Packaging must be opaque, cannot resemble other foods packaged, not attractive to children, tamper-evident, re-sealable if it has multiple servings and child-resistant. The label has to include nutrition facts, a full ingredient list and the universal symbol, demonstrating that it contains cannabis in it. “Statute requires that labels not be attractive to individuals under age 21 and include mandated warning statements and the amount of THC content,” reads the summary. Also, manufacturers cannot call their product a candy.
Foods that require refrigeration and any potentially hazardous food, like meat and seafood, cannot be used in cannabis product manufacturing. They do allow juice and dried meat and perishable ingredients like milk and eggs as long as the final product is up to standards. This will seemingly allow for baked goods to be sold, as long as they are packaged prior to distribution.
Perhaps the most interesting of the proposed rules are requiring written standard operating procedures (SOPs) and following good manufacturing practices (GMPs). Per the new rules, the state will require manufacturers to have written SOPs for waste disposal, inventory and quality control, transportation and security.
According to Donavan Bennett, co-founder and chief executive officer of the Cannabis Quality Group, California is taking a page from the manufacturing and life science industry by requiring SOPs. “The purpose of an SOP is straightforward: to ensure that essential job tasks are performed correctly, consistently, and in conformance with internally approved procedures,” says Bennett. “Without having robust SOPs, how can department managers ensure their employees are trained effectively? Or, how will these department managers know their harvest is consistently being grown? No matter the employee or location.” California requiring written SOPs can potentially help a large number of cannabis businesses improve their operations. “SOPs set the tempo and standard for your organization,” says Bennett. “Without effective training and continuous improvement of SOPs, operators are losing efficiency and their likelihood of having a recall is greater.”
Bennett also says GMPs, now required by the state, can help companies keep track of their sanitation and cleanliness overall. “GMPs address a wide range of production activities, including raw material, sanitation and cleanliness of the premises, and facility design,” says Bennett. “Auditing internal and supplier GMPs should be conducted to ensure any deficiencies are identified and addressed. The company is responsible for the whole process and products, even for the used and unused products which are produced by others.” Bennett recommends auditing your suppliers at least twice annually, checking their GMPs and quality of raw materials, such as cannabis flower or trim prior to extraction.
“These regulations are only the beginning,” says Bennett. “As the consumer becomes more educated on quality cannabis and as more states come online who derives a significant amount of their revenue from the manufacturing and/or life science industries (e.g. New Jersey), regulations like these will become the norm.” Bennett’s Cannabis Quality Group is a provider of cloud quality management software for the cannabis industry.
“Think about it this way: Anything you eat today or any medicine you should take today, is following set and stringent SOPs and GMPs to ensure you are safe and consuming the highest quality product. Why should the cannabis industry be any different?”
I’m not much of an oenophile but I recently came across a very interesting set of documentaries about sommeliers, which are experts on the science of wine and, most importantly, how wines are to be paired with food. What struck me as the most fascinating topic pertained to how mistakes made in the vineyard could be concealed by the barrel in which the wine is stored. For example, if the weather conditions throughout the season had been particularly tumultuous, and you end with sub-optimal grapes that are lacking complexity, then you can compensate for this by aging the wine in a variety of different oak barrels to enhance the flavor. To me, this is synonymous with the way that I’ve seen cannabis concentrates being handled, particularly with respect to terpenes. More specifically, it has recently become somewhat fashionable to supplement cannabis extracts with commercially available terpenes to reestablish an aroma profile that is most representative of the original stock material. Taken one step further, I have even heard of hemp extracts being supplemented with terpenes to achieve a particular strain phenotype, which I cannot imagine pans out very well. In my opinion, this is a very bad idea for two reasons:
One, cannabis is incredibly complex and can contain over 100 different terpene molecules, which can collectively act as anti-inflammatories (Chen et al., 2014), anti- microbial agents (Russo, 2011), sleep aids (Silva et al., 2007), bronchodilators (Falk et al., 1990), and even insulin regulators (Kim et al., 2014). So let’s say that you get your stock material tested and the laboratory screens the product for the top 25 most-prevalent terpenes: alpha- and beta-pinenes, linalool, limonene, beta-myrcene, etc. At that point you utilize this information to supplement your extraction product with these terpenes. However, you still may be missing information about other important molecules such as trans-2-pinanol, alpha-bisabolene and alloaromadendrene that are produced at extremely low, yet therapeutically relevant concentrations in the plant. So essentially with the limited information of the terpenes actually present in your stock material, you would be trying to rebuild a puzzle with only a small fraction of the pieces. Even Ben Affleck’s character in the movie ‘The Accountant’ can’t effectively pull this off.
Secondarily, not all commercially available terpenes are created equal. I’ll be the first to admit that I don’t have decades of experience vetting the quality of terpenes currently on the market; however, the several times that I have thrown samples into the GC-FID (Gas Chromatograph equipped with a Flame Ionization Detector) I have been unpleasantly surprised. Expecting beta-caryophyllene and detecting caryophyllene oxide is frustrating and in my opinion, such inaccuracies are wrong and should not be accepted as colloquialisms.
The moral of the story here is that in order to produce premium cannabis extracts/concentrates, the stock material needs to be handled with extreme care in order to retain the bouquet of terpenes in their natural ratios. This is incredibly important given the volatile nature of terpenes and their seemingly ephemeral, yet vital, nature in cannabis. Thankfully in this bourgeoning industry there are a number of extraction professionals who are delicately navigating the balance between art and science to produce premium products that are incredibly terpene-rich. However, for every alchemyst there is also someone trying to circumvent nature and while as a scientist I am inherently in favor of experimentation, I am also an admirer of natural processes.
Recently Puerto Rico approved the law that regulates the production, manufacturing, dispensing and consumption of medical cannabis. Although medical cannabis was already “legal” through an executive order and was “supervised” by local regulation, there was no law to back up the industry and protect investors.
The creation and approval of laws resides in the hands of elected individuals. Expecting absolute knowledge is unrealistic, especially when we refer to cannabis as a medicine. Sadly, the lack of knowledge is affecting the patients, and an emerging industry that can be the solution to the Island’s current economic crisis.
I am in no way insinuating that Puerto Rico is the only example. I have seen this type of faulty thinking in many places, but cannabis is the perfect manifestation of this human defect. Check some of your laws, and you will find a few that nearly qualify for the same characterization.
As we can see, lack of knowledge can be dangerous. Objective, factual information needs to be shared, and our leaders need a formal education program. Patients need them to have a formal education program to better understand and regulate the drug.
The approval of this law is a significant step for the Island. Still, many Puerto Ricans are not happy with the result. The lack of legitimate information coupled with conservative views made the process an excruciating one. It took many hearings, lots of discussions and created tensions between the government and population, not because of the law, but for the reasons behind the proposed controls. Yes, it was finally approved, but with onerous restrictions that only serve as a detriment to the patient’s health, proving the need for an education program designed specifically to provide data as well as an in-depth scientific analysis of the information, then, you address the issue at hand.
Let’s take a look at some of the controls implemented and the justification for each one as stated by some members of the government.
Patients are not allowed to smoke the flower in its natural state unless it is a terminal patient, or a state-designated committee approves it. Why? Because the flower is not intended for medical use (just for recreational) and the risks associated with lung cancer are too high. Vaporize it.
It was proposed to ban edibles because the packaging makes it attractive for children. Edibles made it, but with the condition that the packaging is monochromatic (the use of one color), yes, insert rolling eyes here.
It only allows licensed pharmacists to dispense medical cannabis at the dispensary (bud tending). The rationale? Academic Background.
The new law requires a bona fide relationship between the doctor and the patient to be able to recommend medical cannabis, even if the doctor is qualified by the state and is a legitimate physician. This is contrary to their policy with other controlled substances, where a record is not required.
When there are different beliefs on a particular topic like it is with medical cannabis, you are not only dealing with the technical details of the subject; there is an emotional side to it too. Paradigms, stigma, stereotypes, beliefs and feelings affect the way we think. We let our judgment get in the way of common sense. When emotions, morals and previous knowledge are hurting objectivity, then we have to rely on scientific data and facts to issue resolution. However, when the conflict comes from opinions, we rely on common sense, and this one is scarce.
Now education: what can education do with beliefs, morals and emotional responses?
David Burns in his book “Feeling Good: The New Mood Therapy” discusses ten thinking errors that could explain, to those like me that want to believe this is a legitimate mistake, that there are cognitive distortions that affect the result of ours thoughts.
Now let’s analyze …
There are many things wrong with this prohibition. First, the flower is natural and organic. It is the easiest to produce and the cheapest alternative for patients; there are more than 500 compounds all interdependent to make sick people feel better. There are seas of data, anecdotal information, serious studies collecting information for decades and opinions of highly educated individuals that support the consumption of flower in its natural state for medical purposes. The benefits are discarded, and personal opinions take the lead. Based on Burns’s work this is a textbook case of Disqualifying the Positive: dismissing or ignoring any positive facts. Moreover, let’s not forget the benefit for illegal growers and distributors.
Keep out of reach of children, does it ring a bell? For years and years, we have consumed controlled substances, have manipulated detergent pods, bleach and so many other products that can be fatal. The warning is enough, just like is done with other hazardous Here we can notice how we can fall into the Fortune Teller Error, which believes that they know what will happen, without evidence.
Not even the largest drug stores in the USA have this requirement. There is one pharmacist per shift, and a licensed pharmacist supervises pharmacy technicians. Medical cannabis is not even mentioned in current Pharmacy’s BA curricula. Most pharmacists take external courses in training institutes. On the other hand, bud tenders go through a very comprehensive certification process that covers from customer service to cash management and safety and of course all technical knowledge. If anything, a botanist (plant scientist) makes more sense. What a splendid example of magnification (make small things much larger than they deserve). This is an unnecessary requirement.
The relationship between a certified doctor and patient has to be bona fide (real, honest). In practical terms, the doctor has to treat the patient for some time (sometimes six months) and have a history of the patient. Even though this sounds logical, not all doctors are certified to recommend cannabis, but all can diagnose. Are we penalizing the doctor or the patient? The only thing that you need to qualify as a patient is the condition. Besides, I had prescriptions filled for controlled medications at the drug store with no history. Why are we overgeneralizing Do we think that all doctors are frauds?
The Pennsylvania Department of Health announced today the first 12 winners of growing and processing permits for the state’s medical cannabis program. At first glance, it appears those who won the permits have teams with experience in successful cannabis operations elsewhere in the country. The permit winners now have six months to become operational, according to a press release.
According to that press release, John Collins, director of the Pennsylvania Office of Medical Marijuana, received 457 applications in total, with 177 prospective grower/processors and 280 for dispensaries. “With today’s announcement, we remain on track to fulfill the Wolf Administration’s commitment to deliver medical marijuana to patients in 2018,” says Collins. “The applications from the entities receiving permits were objectively reviewed by an evaluation team made up of members from across commonwealth agencies.”
In the populous Southeast region of Pennsylvania, grower/processor permits were awarded to Prime Wellness of Pennsylvania, LLC, and Franklin Labs, LLC. Prime Wellness is a Connecticut-based enterprise. According to Steve Schain, Esq., attorney at the Hoban Law Group, Franklin Labs includes team members from Garden State Dispensary, a successful medical cannabis operation in New Jersey.
Two of the businesses that won permits are actually from Illinois, not Pennsylvania. GTI Pennsylvania, LLC (Green Thumb Industries), has a strong presence in Illinois and Nevada. AES Compassionate Care LLC lists their business state as Illinois as well.
“Based on the first phase award of grower/processor licensees both the strength and weakness of Pennsylvania’s program has been highlighted,” says Schain. “Many licensee recipients are affiliated with existing national marijuana-related businesses with excellent track records for operating in a transparent, compliant and profitable manner.” The applications were rated on a scorecard out of 1,000 points. “Unfortunately missing from this initial phase license winners are purely regional enterprises who may have been unable to compete with national concerns’ resources and checkbooks.” According to Schain, some of the more significant areas on the scorecard reflect a diversity plan, community impact statement, business history and capacity to operate, capital requirements and operational timetable. Capital requirements are the applicants’ demonstrable financial resources comprised of at least $2 million in capital and $500,000 in cash. All of the growers are required to grow indoors, not in a greenhouse or on an outdoor farm.
There is also a ten-day appeals process for scorecards that will undoubtedly be utilized by companies that were not successful in their bids. The next phase, according to Schain, of Pennsylvania’s Medical Marijuana Program regards “Clininical Registrants” in which grow/processor and dispensary licensure will be awarded to eight applicants, which, if able to satisfy requirements including demonstrating $15 million in capital, will be authorized to open up to six dispensary locations.
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.
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.
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.”
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.
Edibles and vape pens are rapidly becoming a sizable portion of the cannabis industry as various methods of consumption popularize beyond just smoking dried flower. These products are produced using cannabis concentrates, which come in the form of oils, waxes or shatter (figure 1). Once the cannabinoids and terpenes are removed from the plant material using solvents, the solvent is evaporated leaving behind the product. Extraction solvents are difficult to remove in the low percent range so the final product is tested to ensure leftover solvents are at safe levels. While carbon dioxide and butane are most commonly used, consumer concern over other more toxic residual solvents has led to regulation of acceptable limits. For instance, in Colorado the Department of Public Health and Environment (CDPHE) updated the state’s acceptable limits of residual solvents on January 1st, 2017.
Since the most suitable solvents are volatile, these compounds are not amenable to HPLC methods and are best suited to gas chromatography (GC) using a thick stationary phase capable of adequate retention and resolution of butanes from other target compounds. Headspace (HS) is the most common analytical technique for efficiently removing the residual solvents from the complex cannabis extract matrix. Concentrates are weighed out into a headspace vial and are dissolved in a high molecular weight solvent such as dimethylformamide (DMF) or 1,3-dimethyl-3-imidazolidinone (DMI). The sealed headspace vial is heated until a stable equilibrium between the gas phase and the liquid phase occurs inside the vial. One milliliter of gas is transferred from the vial to the gas chromatograph for analysis. Another approach is full evaporation technique (FET), which involves a small amount of sample sealed in a headspace vial creating a single-phase gas system. More work is required to validate this technique as a quantitative method.
Gas Chromatographic Detectors
The flame ionization detector (FID) is selective because it only responds to materials that ionize in an air/hydrogen flame, however, this condition covers a broad range of compounds. When an organic compound enters the flame; the large increase in ions produced is measured as a positive signal. Since the response is proportional to the number of carbon atoms introduced into the flame, an FID is considered a quantitative counter of carbon atoms burned. There are a variety of advantages to using this detector such as, ease of use, stability, and the largest linear dynamic range of the commonly available GC detectors. The FID covers a calibration of nearly 5 orders of magnitude. FIDs are inexpensive to purchase and to operate. Maintenance is generally no more complex than changing jets and ensuring proper gas flows to the detector. Because of the stability of this detector internal standards are not required and sensitivity is adequate for meeting the acceptable reporting limits. However, FID is unable to confirm compounds and identification is only based on retention time. Early eluting analytes have a higher probability of interferences from matrix (Figure 2).
Mass Spectrometry (MS) provides unique spectral information for accurately identifying components eluting from the capillary column. As a compound exits the column it collides with high-energy electrons destabilizing the valence shell electrons of the analyte and it is broken into structurally significant charged fragments. These fragments are separated by their mass-to-charge ratios in the analyzer to produce a spectral pattern unique to the compound. To confirm the identity of the compound the spectral fingerprint is matched to a library of known spectra. Using the spectral patterns the appropriate masses for quantification can be chosen. Compounds with higher molecular weight fragments are easier to detect and identify for instance benzene (m/z 78), toluene (m/z 91) and the xylenes (m/z 106), whereas low mass fragments such as propane (m/z 29), methanol (m/z 31) and butane (m/z 43) are more difficult and may elute with matrix that matches these ions. Several disadvantages of mass spectrometers are the cost of equipment, cost to operate and complexity. In addition, these detectors are less stable and require an internal standard and have a limited dynamic range, which can lead to compound saturation.
Regardless of your method of detection, optimized HS and GC conditions are essential to properly resolve your target analytes and achieve the required detection limits. While MS may differentiate overlapping peaks the chances of interference of low molecular weight fragments necessitates resolution of target analytes chromatographically. FID requires excellent resolution for accurate identification and quantification.
Last week, the Oregon Health Authority (OHA) published a bulletin, outlining new temporary testing requirements effective immediately until May 30th of next year. The changes to the rules come in the wake of product shortages, higher prices and even some claims of cultivators reverting back to the black market to stay afloat.
According to the bulletin, these temporary regulations are meant to still protect public health and safety, but are “aimed at lowering the testing burden for producers and processors based on concerns and input from the marijuana industry.” The temporary rules, applying to both medical and retail products, are a Band-Aid fix while the OHA works on a permanent solution to the testing backlog.
Here are some key takeaways from the rule changes:
THC and CBD amounts on the label must be the value calculated by a laboratory, plus or minus 5%.
A harvest lot can include more than one strain.
Cannabis harvested within a 48-hour period, using the same growing and curing processes can be included in one harvest lot.
Edibles processors can include up to 1000 units of product in a batch for testing.
The size of a process lot submitted for testing for concentrates, extracts or other non-edible products will be the maximum size for future sampling and testing.
Different batches of the same strain can be combined for testing potency.
Samples can be combined from a number of batches in a harvest lot for pesticide testing if the weight of all the batches doesn’t exceed ten pounds. This also means that if that combined sample fails a pesticide test, all of the batches fail the test and need to be disposed.
Butanol, Propanol and Ethanol are no longer on the solvent list.
The maximum concentration limit for THC and CBD testing can have up to a 5% variance.
Process validation is replaced by one control study.
After OHA has certified a control study, it is valid for a year unless there is an SOP or ingredient change.
During the control study, sample increments are tested separately for homogeneity across batches, but when the control study is certified, sample increments can be combined.
Failing a test
Test reports must clearly show if a test fails or passes.
Producers can request a reanalysis after a failed test no later than a week after receiving failed test results and that reanalysis must happen within 30 days.
The office of Gov. Kate Brown along with the OHA, Oregon Department of Agriculture (ODA) and Oregon Liquor Control Commission (OLCC) issued a letter in late November, serving as a reminder of the regulations regarding pesticide use and testing. It says in bold that it is illegal to use any pesticide not on the ODA’s cannabis and pesticide guide list. The letter states that failed pesticide tests are referred to ODA for investigation, which means producers that fail those tests could face punitive measures such as fines.
The letter also clarifies a major part of the pesticide rules involving the action level, or the measured amount of pesticides in a product that the OHA deems potentially dangerous. “Despite cannabis producers receiving test results below OHA pesticide action levels for cannabis (set in OHA rule), producers may still be in violation of the Oregon Pesticide Control Act if any levels of illegal pesticides are detected.” This is crucial information for producers who might have phased out use of pesticides in the past or might have began operations in a facility where pesticides were used previously. A laboratory detecting even a trace amount in the parts-per-billion range of banned pesticides, like Myclobutanil, would mean the producer is in violation of the Pesticide Control Act and could face thousands of dollars in fines. The approved pesticides on the list are generally intended for food products, exempt from a tolerance and are considered low risk.
As regulators work to accredit more laboratories and flesh out issues with the industry, Oregon’s cannabis market enters a period of marked uncertainty.
