Cannabinoid Research & Pharmacology: A Q&A with Dr. Linda Klumpers

By Cannabis Industry Journal Staff

Dr. Linda Klumpers has a Ph.D. in clinical pharmacology of cannabinoids. Originally from the Netherlands, she began much of her career in studying cannabis there. She now lives and works in the United States, where she has worked on a number of projects, started her own company and is continuing her research on cannabis as an effective medicine.

After studying neuroscience at the University of Amsterdam, she went on to train at the Centre for Human Drug Research and Leiden University Medical Center, where Dr. Klumpers obtained a clinical pharmacology degree and a Ph.D. in clinical pharmacology of cannabinoids. She has been researching cannabinoids in humans since 2006. Dr. Klumpers co-authored a number of peer-reviewed cannabinoid publications and she has received five honors and awards for her work, including the BJCP Prize from the British Journal of Clinical Pharmacology.

In 2016, she moved to the United States and founded Cannify, an online tool that helps patients and clinicians with product matching and providing legitimate cannabis education based in sound science. In 2018, Dr. Klumpers joined forces with Dr. Michael Tagen, another clinical pharmacologist, to launch Verdient Science, a consulting partnership. Their work at Verdient Science includes helping clients set up human studies, advise on FDA submissions, creating course materials, adjusting product pipelines and product development strategies, among other areas of focus.

Right now, Dr. Klumpers is waiting to hear back from a grant application they submitted to study THC and CBD ratios for medical efficacy in chronic pain patients. We sat down with Dr. Klumpers to hear her story, what she is working on now and how she hopes to continue researching cannabis as an effective medicine.

Cannabis Industry Journal: Tell us about your background as a research scientist. How did you get involved in cannabis?

Dr. Linda Klumpers: During my Ph.D. work, we studied the effects of so-called cannabinoid receptor antagonists that block the effects of THC – I prefer to say “we”, as research is always done by multiple people. The problem with studying these compounds in healthy volunteers is that you can’t observe acute effects, which means that you won’t measure any effect after a single dose. To circumvent this issue, we applied a trick and developed a ‘challenge test’: after you give the ‘invisible’ blocking compound, you stimulate the cannabinoid system by giving people THC. If the subjects don’t feel the effects of THC, you know that the blocker worked. One thing lead to another and we ended up studying various administration methods, such as intrapulmonal (via the lungs) with vaporization, oral and sublingual. We studied the behavior of cannabinoids in the body and how the body responded to them.

CIJ: Can you share some information on the projects you are working on? What is Cannify and what is Verdient Science?

Dr. Klumpers: Cannify was founded in 2016 after I saw that too many people had opinions about cannabis that were more based on emotion than fact. Besides, I noticed that a majority of the scientific literature on cannabis pharmacology was left unnoticed and unapplied to the people getting exposed to cannabis, such as patients, the cannabis industry – that was in a very different stage at that time – healthcare providers and regulators. With my Ph.D. in cannabis pharmacology, I wanted to add a level of objectivity to cannabis education and research. Cannify’s goals are to understand the science of cannabis, and share this with others.

The way we do this is multi-fold:

Cannify Quiz: Patients with an interest in cannabis often want to know the science about cannabis and their condition. Our quiz helps these people by asking in-depth questions and showing them relevant scientific literature in a personalized report. After that, an overview is given with products and product matching scores. Our account system allows users to track their progress over time. Product manufacturers, dispensaries and other companies can use the quiz for their websites and their stores to help out retail employees and save them time, and to receive insight with our analytics on customer desires and behavior. Needless to say, an educated customer is a better customer. It is important that customers come and leave stores well-informed.
Education: Speaking of education, our website contains educational articles about everything cannabis: from plant to patient and from product to mechanism of action. We regularly publish educational quizzes for people to test their knowledge level. With a free Cannify account, you can find all of our educational quizzes and save your results. We also provide customized courses, and have educated a wide audience varying from industry professionals to CME-accredited courses for healthcare providers. On top of that, our educational videos in dispensaries (in collaboration with our partner, Enlighten) reach customers and retail employees.

Research: To expand the knowledge on cannabis, performing and especially sharing research is essential. We have already performed and published some of Cannify’s results on descriptive statistics and effect prediction during conferences, as well as a review paper on cannabis therapeutics in a peer-reviewed journal and a book chapter. This year, we expect to co-publish the results of a survey in different sleep patient groups. We collaborated with the Centre of Excellence for Epilepsy and Sleep Medicine in the Netherlands on a peer-reviewed paper from which we expect new research to follow to benefit these patients. We have also co-submitted a grant to study THC and CBD ratios in chronic pain patients: fingers crossed! Another important next step is to test a healthcare provider-specific version of Cannify’s quiz in the clinic once COVID dies down. I want to add that after working in a clinical lab for many years, it is important to combine the results of clinical trials to what people do in real life, which is what we do with Cannify.

And here’s some information on Verdient Science:

Verdient Science is a consulting partnership I have with clinical pharmacologist Dr. Michael Tagen. We provide clinical and translational pharmacology expertise to improve the quality of product development & clinical testing. While both working as independent consultants, we decided from 2018 to start working together to offer better services. Since then, our work has been very variable and includes helping clients set up human studies, advise on FDA submissions, creating course materials, adjusting product pipelines and product development strategies to make them more efficient and cheaper, performed scientific due diligence and much more. When clients want additional services that are beyond our expertise, we are typically able to introduce them to various people per expertise area, or refer them to our partner companies, Complex Biotech Discovery Ventures (CBDV) with Dr. Markus Roggen, and Via Innovations with Dr. Monica Vialpando. A benefit of working with the same partners includes smooth handovers and the feeling of a one stop shop.

CIJ: How does Cannify match available products to consumer needs? Is there an algorithm you developed that matches moods or feelings to cannabinoids or chemical profiles?

Dr. Klumpers: That is a great question and the core of what we do! So back to the Cannify quiz: there are three steps:

Users fill in questions;
A personalized report is generated with the relevant science;
The user gets a product overview with product matching scores.

The report and the matching scores are generated using algorithms that are regularly updated. These algorithms are based on various data sources:

Literature: There is a lot of available literature, and we make sure to select the most relevant and reliable studies;
Raw data: There is only so much one can find in the literature, and lots is hidden in the raw data. Therefore, we piled up data from studies done at various research institutions, including the University of Kentucky and Johns Hopkins University, and used them in our algorithms;
Internal studies: From the thousands of users filling in their results, there is a lot of information that we should learn from. This feedback loop helps us to better understand how the lab relates to real life situations.

CIJ: The world of cannabis research has been historically stymied by red tape, DEA interference and a host of federal regulations. How have you managed to work through all that? Do you have a DEA license? What did it take to get it?

Dr. Klumpers: Luckily, a majority of our research was and is done outside of the US. You still need to obtain the appropriate licenses, but I was perhaps lucky to have filled in every form very thoroughly and we got the licenses within months. The process is quite meticulous, as you need separate licenses for almost every step from manufacturing to administration. An additional complication is that our cannabis is not stored in our own building, but in the hospital pharmacy across the street, involving transport via the public road. Despite the roadblocks, including a legal procedure about this matter that was going on in parallel, I had no major issues getting our work done. For our research in the US, we were lucky to have been working with partners that already have the required license.

Also with publishing, I have never had an issue with the cannabis stigma. Generally, in my field of science, good quality science is very much welcomed and appreciated, and this was even before the time that there were four different cannabis-related journals, as is the case nowadays.

CIJ: Looking to the future, where do you hope to focus your research efforts? Where do you think the cannabis community should be focusing their efforts in the next 5-10 years?

Dr. Klumpers: Besides continuing to analyze the data generated from Cannify, I keep my fingers crossed for the grant application I mentioned earlier on THC and CBD ratios in chronic pain patients. Although we know that CBD is able to influence THC-induced effects, it is not known at what dosages, which ratios and how the effects are related to each other. For example: is CBD able to decrease certain side-effects of THC without decreasing pain-relieving effects?

Whatever is done, wherever in the community: good quality data are keyNext to that, I am also interested in other neurological and psychiatric disorders, and, of course, my Ph.D. love: the cannabinoid antagonists. Sadly, all the research efforts on this compound group were halted more than a decade ago. However, there is a renewed interest. I would love to help turn these compounds into effective and safe medicines.

Regarding the cannabis community: 5-10 years sounds really far away for an industry that is relatively new to many, but a lot has already changed since I started cannabis research more than 14 years ago and time has flown by. Some changes have been positive and others less so. Whatever is done, wherever in the community: good quality data are key. Many companies gather data and even publish them in peer-reviewed journals, but that does not always mean that the data are useful or that the studies were done well. Only a few minor changes to how and which data are gathered, and so much more can be done. What can help with achieving this is to let the right people do the right thing: many call themselves a ‘cannabis scientist’ or ‘cannabis expert’, but that does not mean anything. What has someone truly achieved and what is their exact expertise? A Ph.D. in chemistry is not going to help you in setting up effect studies, neither will I be able to improve your product’s shelf life or extraction yield. Getting the right people in the right place is key. Lastly: the cannabis community should stay critical. The length of one article in Cannabis Industry Journal wouldn’t be enough to lay out all the misconceptions that people have about cannabis. Make sure that those misconceptions do not live on and do not be afraid to admit you don’t know something, irrespective of the branch you work in: only then, can the cannabis community progress to the benefit of all.

Will Australia’s Cannabis Program Follow Canada’s Lead?

By Marguerite Arnold

No Comments

The news is intriguing in a world overwhelmed with pandemic news. THC Global, a Canadian-Aussie company now raising money and signing global deals, has just bought a “clinic network” of 30 prescribing physicians that will be able to supply up to 6,000 Australian patients this year.

In doing so, this entity is clearly beginning to establish a pattern of expansion in a new medical market not seen so far outside of Canada. Namely being able to obtain the all-important prescription for one’s brand at the doctor or prescriber’s office which is affiliated with a certain producer. Pharmacies and dispensaries downstream have no discretion for any other product to sell if the brand is written right on the prescription itself.

And this marks a new step in an industry frustrated with the high prices and high levels of red tape in other international environments where more widespread medical cannabis reform has come.

The Situation in Germany
Germany represents, so far at least, the destination market of choice for Canadian cannabis firms (for the last several years at least). This is for several very sound business reasons (at least in theory).

The German medical market is the largest in Europe. Health reforms which swept the country at the time of reunification also created a system that is in its own way a hybrid of the more European (and British) NHS and American healthcare. Namely, 90% of the German population is on the system, but it is tied to employment and income. Freelancers, even of the German kind, must use private healthcare as must all non-passport foreigners. If you make over a certain amount of money (about $65,000), you must also pay for private healthcare. As the cannabis revolution rolls forward, many cannabis patients are caught in changing rules and a great reluctance by public health insurers to allow fast entry of any new drug, including this one. This is based on “science” but also cost.

Bottom line? Yes, the market is lucrative and growing, and yes, cannabis is covered under public health insurance, but the ability of any producers to be able to maintain a reliable, steady market of “prescribers” is highly limited. Furthermore, unlike anywhere else in the world, pharmacists play an outsized role in the process – namely because there are no chains (more than four brick and mortar outlets are verboten). Prices and availability vary widely across the country.

There are also no “online” drug stores where patients can send prescriptions in the sense that this vertical has developed in other countries.

Hospital dispensation is, for all the obvious reasons, highly expensive and generally prohibitive for the long term, if not serving much larger numbers of patients.

The Problem in the UK
Like Germany, the UK decided to launch medical “cannabis” – or at least cannabinoid-related drugs under the purview of the NHS, but there are several issues with this.

The problems start with the fact that the system remains a monopoly for one British company, GW Pharmaceuticals. The medication produced by them, including Sativex and Epidiolex is expensive and does not work for many patients that it is produced “on label” for (such as MS or childhood epilepsy).

And then of course, the largest group of cannabis patients anywhere (chronic pain) have been explicitly excluded from the list of conditions cannabis can be prescribed for under public health guidelines in the UK. This, like Germany, has created a highly expensive system where those patients who obtain the drug on a regular (and legal basis) have to have both private healthcare and obtain help through private clinics. While there are several chain clinics now forming in the UK, this is not the same thing as “buying” patients in the thousands – the model seen in Canada from the beginning of 2014.

The market has a lot of potential, in other words, but like Germany, via very different paths to market than seen in Canada, in particular.

Why Is Canada Different?
The development of the medical market came through federal change in the law around the turn of the century. Namely, after patients won the right to grow for themselves, via Supreme Court legal challenge, patient collectives gradually formed to grow and sell cannabis that was more “professionally” cultivated. This, in turn, became the right of private companies and indeed household names in the Canadian market saw buying patient pools as their path to financing on the equity markets as of 2014.

This is not widely popular within the industry. Indeed, the last legal challenge mounted by the industry to ban non-profit patient collectives fell apart in 2016 – the year that the larger Canadian companies began to look abroad to Europe.

It is also undoubtedly why, beyond the red tape they face in Germany and the UK if not across Europe, Canadian firms are looking to hybridize a model which worked well for them at least in the early days of capitalization of the private industry. And maybe Australia will be “it.” Stay tuned.

FDA Issues Update on CBD: Still Working, Still Waiting

By Aaron G. Biros

No Comments

On March 5, 2020, the U.S. Food and Drug Administration (FDA) issued a press release to the public about their work on devising a regulatory framework for cannabidiol (CBD) products. The FDA also submitted a report to Congress on their rulemaking progress.

The main theme of the report is the same story we’ve been hearing from the FDA for a while now: They are still working on figuring out how to regulate CBD products and wants to do more research before they tackle the rulemaking.

The most intriguing new development from this report is the FDA’s newfound interest in regulating CBD products like dietary supplements:

“FDA is actively considering potential pathways for certain CBD products to be marketed as dietary supplements. Under current law, CBD products cannot lawfully be marketed as dietary supplements, but FDA has the authority to create an exemption through notice-and-comment rulemaking that would allow products containing CBD to be sold legally as dietary supplements.”

If you’ve been living under a rock for the past couple years, here’s a recap: In June of 2018, the FDA approved GW Pharma’s drug, Epidiolex, for the treatment of rare forms of epilepsy. This allowed a drug containing CBD to go to market, but only through the agency’s drug approval process. When the 2018 Farm Bill (Agricultural Improvement Act of 2018) was signed into law in December later that year, the federal government removed cannabis (hemp) with less than 0.3% THC from the Controlled Substances Act, essentially legalizing it on a federal level. Congress tasked the FDA with figuring out how to regulate the market. Without any FDA guidance in the early days, the subsequent market growth created mass confusion for the industry and consumers alike, with no one really knowing if selling CBD products is legal or not. In May of 2019, the agency held a comment period and public hearing on CBD, which included a lot of discussion around the benefits, the risks and further research on CBD. Throughout 2019, the FDA sent a large number of warning letters to companies marketing CBD products with unsubstantiated health claims. Towards the end of 2019, Congress passed a bill mandating that the FDA update them on their progress to regulate the market within 60 days. That deadline came and went, and then the FDA issued the public update and submitted the report mentioned above to Congress last week.

The FDA says they intend to take a number of steps towards providing some market clarity, while still protecting the public from unknown risks. Firstly, they want to educate the public more about potential risks associated with CBD. “We remain focused on educating the public about the number of questions that remain regarding CBD’s safety,” reads the update. “There may be risks that need to be considered before using CBD products outside of the monitored setting of a prescription from your health care provider.” Those concerns mentioned above include potential liver injury, drug interactions, reproductive toxicity and more benign side effects like drowsiness.

The agency also wants to try and close knowledge gaps in the areas of safety and potential benefits. In this section of the update, the agency asks industry stakeholders for help. “We’re seeking reliable and high-quality data.” The agency is requesting data on sedative effects, impacts of long-term use, pharmacokinetics, safety of various drug delivery mechanisms, safety for animals, different processes for full or broad spectrum or isolate derivation, among other areas of interest. They plan to re-open the public docket from the public hearing back in May 2019, extending the comment period indefinitely as a tool for stakeholders to share information with the FDA.

As far as enforcement actions go, the agency wants to take a risk-based approach to it. While there is still no official enforcement policy, the FDA is working on it. Their biggest concern is with companies marketing CBD products using drug and health claims, which could “deter consumers from seeking proven, safe medical therapies for serious illnesses – potentially endangering their health or life.” The agency is also worried about potential contamination risk and consumer exposure to things like residual solvents and heavy metals. Their last concern in this area involves truth in labeling, like making false label claims, not listing every ingredient or incorrectly stating the amount of cannabinoids in the product.

“Our ongoing efforts related to CBD, including the steps we’re announcing today, are in line with our mission to protect the public, foster innovation and promote consumer confidence. We recognize the significant public interest in CBD and we must work together with stakeholders and industry to develop high-quality data to close the substantial knowledge gaps about the science, safety and quality of many of these products. We are committed to working efficiently to further clarify our regulatory approach to these products – as always, using science as our guide and upholding our rigorous public health standards.”

Overall, the public update and the report don’t disclose anything groundbreaking. They do, however, provide some much-needed guidance for the CBD market on how stakeholders can help the FDA’s efforts. The fact that they are investigating dietary supplements as a path toward a regulatory framework is the by far the biggest take away from all this.

Cannabis Extracts for the Informed Consumer: Solvent or Solventless

By Nick J. Bucci

Editor’s Note: Nick Bucci is a freelance cannabis writer. You can view his work here

As cannabis markets continue to gain traction, inconsistent and largely unpredictable markets have left recreational consumers in an informational fog. Try as the industry may, or may not to inform consumers, the lack of knowledge was evident when an established Colorado hash company opened a second operation in California. Expecting high demand for their solventless concentrates, the demand for their solvent-based counterparts came as a surprise. Initially hoping to eliminate solvent extracts from their product line-up, the company was forced to devote about half their overall production to solvent extracts, until information spreads and attitudes start to change. Over the past year several companies have joined the solventless side of history, but consumer understanding remains largely stagnant. For those immediately overwhelmed by terminology, cannabis extracts, concentrates or hash are all interchangeable terms describing concentrated cannabis. Under these umbrella terms, two distinct categories emerge depending upon whether chemical solvents were or were not used to extract the hash. Hence: solvent or solventless. A brief overview of cannabis concentrates will help consumers to understand the evolution away from solvent extractions and toward a superior solventless future.

ecxtractionfig2 — Science and economics merge when considering all the possible uses of concentrated compounds to final product formulations

Before regulated cannabis markets, cannabis extracts had long been in use. These old-world methods of cannabis extraction use very basic solventless techniques to create more potent, concentrated forms of cannabis. Dry sifting is easily the oldest form of cannabis extraction and a prime example of one solventless technique. Something as simple as shaking dried cannabis over metal screens and collecting the residue underneath creates a solventless product called keif. Dark brown bubble-hash, made popular decades ago, is another ancient technique using only ice and water to perform extractions without chemical solvents. After decades of stagnant and limited old-world methods, changes in legislation allowed cannabis sciences to flourish. These old-world hash methods were quickly forgotten, replaced by the astonishing progress of modern solvent extractions.

Tetrahydrocannabinol (THC), just one of hundreds of cannabinoids found in cannabis.

The emergence of solvent extracts revolutionized cannabis around 2011, creating new categories of cannabis products that exploded onto the scene. Not only did solvent extracts produce the most potent and cleanest forms of hash ever seen at this point, it also created new possibilities for hash-oil vape cartridges and cannabis extract infused edibles. These solvent extracts use butane, propane, or other hydrocarbon solvents to extract, or “blast” cannabinoids from the plant. By running solvents through cannabis and then purging or removing leftover, residual solvents, a super-potent, premium hash product is achieved. Regulated markets require testing to ensure only a safe level, if any, of the solvent used in the extraction process remains in the final product. This technology ushered in the first wave of concentrates to medical and recreational markets under the descriptive titles of wax, shatter and crumble. While these effective and affordable products can still be found today, far superior products have largely replaced wax and shatter. Distillation techniques can further purify and isolate THC-a, while removing harmful residual solvents. For a time, Solvent-free was used to describe this ultra-purified distillate, but the needless term has fallen out of use. Solvent-free is still a solvent extraction using chemical solvents, don’t be fooled. Distillation and CO2 extractions have fallen into general disfavor as they destroy the flavorful terpenes and valuable cannabinoids, that when present create an “entourage effect.” This “entourage effect” happens when the medicinal and recreational properties are most effective, pronounced, and impactful due to a full range of terpenes and cannabinoids being present in the final product. With companies manually reintroducing terpenes to their final extracts, it’s an attempt to restore what was lost during solvent extraction processes. Many brands claim to use cannabis derived or food-grade terpenes to infuse or reintroduce terpenes into their purified hash oils. While this adds flavor and taste, especially to distillate cartridges, it’s far from an ideal solution. Armed with this new information, the informed consumer looks for a full profile of terpenes and cannabinoids in their hash.

With terpene preservation a new priority, all aspects of hash making were reevaluated. By using fresh-frozen cannabis flower, solvent extractions quickly reached new heights. Using the same techniques as prior solvent extractions, the cannabis plant is frozen immediately upon harvesting, rather than trimming and drying the crop as usual. Freezing the plant preserves valuable terpenes helping to create a new category for hydrocarbon extracts under the general label of live resins. This live resin, containing vastly greater profiles of terpenes and cannabinoids than earlier waxes, shatters or crumbles is sold as live-resin sauce, sugar, badder, frosting, diamonds and more. Many versions of live resin re-use previous terms that describe consistencies. These live resin solvent extracts outperform the wax, crumble and shatters of old, and are priced accordingly. Some of the best solvent extracts available today use butane to extract hash oil, which forms THC-a crystals and diamonds seen in live resin sauces. Having learned the value of terpenes and cannabinoids, early efforts to purify THC were clearly misled. The industry defining use of fresh-frozen cannabis flowers greatly improved the quality of all extracts having realized the psychoactive effects are largely dependent on the various profiles of cannabinoids and terpenes. Pure THC-a crystals and isolates are easily achieved with solvent extractions but, produce inferior effects both medicinally and recreationally. Discovering the “entourage effect” as described earlier, these elements of cannabis allowed old-world solventless techniques to be re-inspired and reinvigorated with the benefit of healthy genetics and a hearty understanding of past mistakes.

Having gone full circle, solventless techniques are again at the forefront of the cannabis industry, having attained near perfection for our current understanding of cannabis anatomy.

figure1 extract — The increasingly finer mesh works to separate and extract microscopic trichomes

Using the lessons and tendencies of prior extractions, the solventless method, in all its final forms, begin with the same initial process to make ice-water hash oil. Often referred to as solventless hash oil (SHO), fresh-frozen flowers are submerged in ice and water, soaked and agitated before the water is filtered through mesh screens. As these mesh screens are measured by microns, the increasingly finer mesh works to separate and extract microscopic trichomes that break free from the cannabis plant. The 120- and 90-micron mesh screens usually collect pristine trichome heads. After scraping the remaining material from the screens, its sieved onto trays where the hash can dry using modern techniques of sublimation. The results are beyond phenomenal and are sure to shock even life-long cannabis consumers. This technique isolates only the most potent and psychoactive parts of the plant, to produce white to clear solventless ice water hash. When done with precision 6-star ice water hash is formed. The hash can be sold and consumed as is or undergo additional solventless techniques to produce hash-rosin. Not to be confused with live-resins, rosin uses pressure and slight heat to squeeze ice-water hash, into hash-rosin. Some companies have elected to whip their rosins into a solventless badder or allow their hash rosins to undergo a cold cure process that creates textures and varieties like hash rosin sauce. Regardless of the final solventless product, they all begin as ice water extractions. These simple, natural methods of extraction are quickly being adopted by companies known for live resin. As solventless extracts are safer, cleaner and superior in quality to solvent chemical extractions, the race is on as the industry shifts toward a solventless future.

While I’d be happy to never see another solvent extract again, without the miraculous breakthroughs and advances in all aspects of cannabis manufacturing and production we may have not yet arrived where we are today. When using solvents to extract, the trichomes, which contain the full spectrum of terpenes and cannabinoids, are dissolved by the solvent, which is then evaporated off, leaving behind dissolved trichomes. In solventless hash, these trichomes remain whole and are never dissolved or broken down. Instead they are broken free by agitation in ice and water, separating the trichome heads from their less-active stems. These valuable trichomes heads contain everything pertinent and are never destroyed, dissolved or melted like solvent-extractions are forced to do. The benefit of keeping the heads of these trichomes whole results in a far superior product expressing the full profile of terpenes and cannabinoids the way mother nature intended. This natural profile of trichomes lends itself directly to the entourage effect that solvent extracts were found to be missing.

Extraction techniques are not equal and depend upon whether quality or mass production is the aim. Solvent extracts have quickly begun to represent the old-guard of mass-produced cannabis concentrates, with the solventless new-guard focusing on quality, small batch, hash-rosin excellence.

Beyond THC: Encouraging Cannabinoid and Terpene Production with LEDs

By Andrew Myers

No Comments

For years, tetrahydrocannabinol (THC) got all the attention. While THC certainly delivers its own benefits (such as relaxation and pain relief), there’s a whole host of other – and often overlooked – compounds found in cannabis with important benefits as well. THC is truly only the tip of the iceberg when it comes to cannabis’s potential.

As the cannabis industry evolves with changing consumer tastes and developing medical research, growers may employ techniques to boost cannabinoid and terpene profiles in their harvests – beyond merely focusing on THC. Advanced LEDs allow growers to elicit specific biological responses in cannabis crops, including increased concentrations of these naturally occurring chemical compounds.

The Foundation of Cannabis’s Effects
Whether used medicinally or otherwise, cannabis has changed our society and many of our lives – and there’s a collection of naturally occurring chemical compounds, known as cannabinoids and terpenes, to thank.

The cannabinoids THC and CBD are the most common and well-researched, however they are accompanied by more than 200 additional compounds, including cannabinol (CBN), cannabigerol (CBG) and tetrahydrocannabivarin (THCV), among others.
The cannabis plant also contains terpenes. These structures are responsible for giving flowers (including cannabis), fruits and spices their distinctive flavors and aromas. Common terpenes include limonene, linalool, pinene and myrcene.

Both cannabinoids and terpenes are found in the cannabis plant’s glandular structures known as trichomes. Look closely, and you’ll notice trichomes coating the cannabis flowers and leaves, giving the plant an almost frosty appearance.

macropistil/trichome — A macro view of the trichomes and pistils on the plant

Trichomes – which are found across several plant species – are a key aspect of a cannabis plant’s survival. The specific combination of metabolites produced by trichomes may attract certain pollinators and repel plant-eating animals. Moreover, trichomes (and specifically THC) may act as the plant’s form of sunscreen and shield the plant from harmful ultraviolet rays.

While they play an essential part in the cannabis plant’s lifecycle, trichomes are volatile and easily influenced by a range of environmental factors, including light, heat, physical agitation and time. Therefore, environment is a defining variable in the development of these important structures.

How LEDs Support Cannabinoid and Terpene Development in Crops
Spectrally tunable LEDs give indoor cannabis growers unparalleled control over their crops. As research has expanded about plants’ responses to the light spectrum, growers have discovered they are able to elicit certain physiological responses in the plant. This phenomenon is called photomorphogenesis. At its root, photomorphogenesis is a survival tactic – it’s how the plant responds to miniscule changes in its environment to increase the chances of reaching full maturity and, eventually, reproducing. While cultivated cannabis plants won’t reproduce at an indoor setting, growers can still use the light spectrum to encourage strong root and stem development, hasten the flowering process and the development of bigger, brightly colored flowers.

It makes sense that using the proper light spectrums may also have an impact on the production of specific cannabinoids and terpenes – an important factor when responding to highly specific consumer needs and desires, both within medical and adult-use markets.

Here are a few more reasons why utilizing full-spectrum LEDs can lead to higher quality cannabis:

Lower Heat, but the Same Intensity.
When compared to HPS, fluorescent and other conventional lighting technologies, LEDs have a much lower heat output, but provide the same level of intensity (and often improved uniformity). This represents an enormous advantage for cannabis cultivators, as the lights can be hung much closer to the plant canopy without burning trichomes than they would be able to with other lighting technologies.
UV Light. Cannabinoids and terpenes are part of the cannabis plant’s natural defense mechanism, so it makes sense that lightly stressing plants can boost cannabinoid and terpene numbers. Some studies illustrate an increase in UV-B and UV-A light can lead to richer cannabinoid and terpene profiles.¹ It’s a fine line to walk, though – too much UV can result in burned plants, which leads to a noticeable drop in cannabinoids.
Full-Spectrum Capabilities. The cannabis plant evolved over millions of years under the steady and reliable light of the sun. Full-spectrum is the closest thing to natural sunlight that growers will be able to find for indoor growing – and they’ve been shown to perform better in terms of cannabinoid development. A 2018 study titled “The Effect of Light Spectrum on the Morphology and Cannabinoid Content for Cannabis Sativa L.,” explored how an optimized light spectrum resulted in increased expression of cannabinoids CBG and THCV.²

This is the most important tip for indoor growers: your plants’ environment is everything. It can make or break a successful harvest. That means cultivators are responsible for ensuring the plants are kept in ideal conditions. Lights are certainly important at an indoor facility, but there are several other factors to consider that can affect your lights’ performance and the potency of your final product. This includes your temperature regulation, humidity, the density of plants within the space, CO2 concentration and many other variables. For the best results, your lights should be fully aligned with other environmental controls in your space. Nothing sabotages a once-promising crop like recurrent issues in the indoor environment.

Cannabinoids and terpenes take time to develop – so cultivators will want to avoid harvesting their plants too early. On the other hand, these compounds begin to degrade over time, so growers can’t wait too long either.

Cultivators seeking potent cannabinoid and terpene profiles must find a happy medium for the best results – and the best place to look is where cannabinoids and terpenes develop: the trichomes. With a microscope, cultivators can get up close and personal with these sparkly structures. Younger plants begin with clear trichomes, which eventually become opaque and change to amber. Once your plants show amber-hued trichomes, they’re ready for harvest.

The truth here is that there’s no perfect formula to elicit show-stopping cannabinoids and dizzying terpenes with every harvest. A lot of cannabis cultivation is based around trial-and-error, finding what works for your space, your business and your team. But understanding the basics around indoor environmental controls like lighting and temperature – and how they can affect the development of cannabinoids and terpenes – is an excellent place to start. Using high quality equipment, such as full-spectrum LED lighting can boost both cannabinoid and terpene production, resulting in richer, more potent and higher quality strains.

From MedTech to Cannabis: A Q&A with Jennifer Raeder-Devens

By Aaron G. Biros

No Comments

Project Yosemite, a cannabis product innovation and brand development company, announced earlier this month the appointment of Jennifer Raeder-Devens as their new Chief Scientific Officer. Raeder-Devens is a veteran of the MedTech industry, working for companies like Becton Dickinson, Cardinal Health, Medtronic and 3M.

Prior to joining Yosemite, she was the Vice President of Research & Development at Becton, Dickinson, where she oversaw product development and technology strategies to launch infection prevention products including the ChloraPrep first-in-the-US sterile solution patient preoperative topical antiseptic. She was previously the Vice President of R&D, Strategy and Innovation at Cardinal Health. She’s also held roles at Medtronic, 3M Drug Delivery Systems and 3M Skin Health Division and she has a number of patents in drug delivery and medical devices.

Jennifer Raeder-Devens, Chief Scientific Officer at Project Yosemite

In November of 2018, Project Yosemite launched their first product, OLO, which is an infused, controlled-release sublingual strip. Part of Raeder-Devens’ new role at the company is the continued development and expansion of the OLO sublingual strip technology platform. Andrew Mack, CEO and founder of Project Yosemite, says he’s thrilled to have Raeder-Devens on the team. “Jennifer is an extremely accomplished scientist and engineer with extensive experience driving innovation and R&D in the pharmaceutical and medical device industries,” says Mack.

We caught up with Jennifer over the phone to talk about her background in the MedTech space, why she decided to jump ship to join the cannabis industry and what she’s excited to work on now.

Cannabis Industry Journal: Can you tell us about your background, including your work with 3M and Medtronic?

Jennifer Raeder-Devens: I’m coming directly from Becton Dickinson, a global med tech company, where I supervised the development of drug-device combination products for topical antiseptics. I spent about 10 years there, mostly in topical drug and combination product development. Prior to that, I was at 3M and Medtronic working in drug-device combination products. At 3M, I was supervising a team of technology developers for the 3M Drug Delivery Systems business. I had experience working with designing and manufacturing transdermal, nasal, buccal and inhalation drug delivery mechanisms for pharmaceutical partners.

I worked on implantable drug delivery systems at Medtronic, which included working on the biocompatibility of things like pacemakers and drug infusion pumps and optimizing them to reduce infection and enhance healing after the implantation procedure.

CIJ: What made you consider joining the cannabis industry?

Jennifer: With my work in topicals, transdermal and inhalation drug delivery, I had an easy understanding of the different routes of administration we see today in the cannabis industry. And so, from the technology standpoint, I thought this was a place I could contribute to immediately. And then what got me really excited about it was thinking about cannabis, and just like any other drug, with oral drug delivery, you’ve got first class metabolism and side effects from the 11-Hydroxy-THC that are undesirable and you’d rather not have delivered through the gut.

OLO sublingual strips have a 10-minute onset time

I got excited when I saw the development of things like sublingual strips that were focusing on alternatives to smoking that would preserve that relatively fast onset and mitigate some of the side effects of edibles.

The other thing I really like about the cannabis industry: Previously I have been very focused on known drugs that are already approved and repurposing them into a new delivery system. What really interests me about the cannabis industry is the active cannabinoids and terpenes are somewhat known and somewhat unknown, so there is this really interesting challenge there of trying to separate the wheat from the chaff in terms of producing therapeutic effects.

It is a really interesting space where the indications of certain molecules are evolving along with the delivery technology. So, it is a really exciting and eye-opening way to take the next step in my career and have this wide-open space in front of me, both in terms of the different cannabinoids, their effects and the delivery systems we can use.

CIJ: How might you be prepared, given your background, for some of the challenges in the cannabis space?

Jennifer: I think the challenges in cannabis delivery are not different from the challenges in pharmaceutical drug delivery. It’s just that we have this additional complexity of the entourage effect. We can be engineering not just the main ingredient of THC, but also all the other cannabinoids and terpenes. So, for example, with my background in infection prevention, we build a product that we know reduces the risk of infection, but we are really challenged to actually prove it reduces the risk of infection. We have a similar situation in the cannabis industry, where we can get the THC, or CBG or CBN where we want it to go, but then we are really challenged to figure out how we can find, what we call in the pharmaceutical industry, a surrogate end point for efficacy, so that we can test that product and really believe that when we put the product on the market, even though we haven’t tested thousands of users or conducted large randomized clinical trials, that the effect will be shown. We are networking and partnering with a good scientific community to build the right product and do some testing at a small scale that really demonstrates the product achieves the effect that we are really looking for.

CIJ: Can you tell us a little about your new role with Project Yosemite?

Jennifer: My job description falls into three buckets: The first part is that we are forming a scientific advisory board and we are working with some of the leading cannabinoid researchers around the country and around the world. These are the people identifying whether or not certain cannabinoids could reduce cancer cell metabolism or whether cannabinoids contribute to weight loss or diabetes control and other things of that nature. We are trying to reach as far upstream as we can to grasp the emerging understanding of the performance of cannabinoids and terpenes in the endocannabinoid system. So, part of my job is to chair that scientific advisory board, get the thought leaders together in the room and have them bring their knowledge and explore with our own knowledge what cannabis can really do.

The OLO sublingual strips

I have worked in topical, transdermal, buccal, nasal, inhalation drug delivery. In the second bucket of my job, we are trying to understand a given indication or experience that our users want to have, what would be the right route for them. We are challenging our sublingual delivery mechanism to see how fast of an onset we can really get. Right now, we are at 10 minutes for drug delivery in sublingual and we are still trying to get an even faster onset time for the sublingual strip.

For other indications, like chronic pain, we may want to think about a sustained release, so sort of aligning the different indications with which different cannabinoids and terpenes will work for it and see which delivery platform will work for what we are trying to accomplish in each indication. So, we do not plan to remain solely a sublingual strip company, but will build out additional delivery platforms as we develop new indications.

Right now, we are working upstream with the growers and the processors to get cannabis oil and extracts. Some of the growers are working on different genetics in their cultivars to grow plants that have different ratios of different cannabinoids that we know from the emerging research will have an impact on people’s experience. Now we are working with growers to really get ahead of the curve on how to formulate products with various cannabinoids.

We have an R&D team in house that I supervise. We are always working with our production team to make small improvements such as the faster onset and the dissolution rate and things like flavors, which covers a downstream focus as well.

Spotlight on Encore Labs: Servicing the Cannabis Market in California

By Kristen Hogerheide

No Comments

Encore Labs is a full-service cannabis testing lab in Pasadena, California, providing all testing needs required by California’s Bureau of Cannabis Control (BCC). The BCC requires that cannabis products being sold in licensed dispensaries be tested for cannabinoid potency, heavy metals, microbial impurities, moisture content and water activity, mycotoxins, residual pesticides, residual solvents and processing chemicals, foreign materials and terpenes. It is Encore Labs’ goal to guarantee the quality and potency of all cannabis products while ensuring regulatory guidelines are met in the state of California.

Encore Labs provides quick turnaround times on a consistent basis. They take pride in offering excellent customer service without diminishing the quality of the work that they do. Their team of laboratory analysts/technicians are passionate about the industry and will never compromise their integrity just to make an extra buck.

Co-Founder, Spencer Wong, mentions their personal connection with clients. “Our customers don’t just see us as their testing laboratory, they see Encore Labs as their laboratory partner,” says Wong. “Besides performing analytical testing, we have worked with many customers to help formulate new products and do root cause analysis to pinpoint inefficiencies in their manufacturing operations and cultivation farms.”

ISO/IEC 17025 Accreditation has been extremely valuable to Encore Labs, especially regarding the new cannabis testing industry. “Our experience with Perry Johnson Laboratory Accreditation, Inc. has been great and has allowed for a very smooth and straightforward initial accreditation process. Their staff has been knowledgeable and responsive every step of the way,” says Wong.

Accreditation establishes that steps are being taken regarding quality and that laboratories are meeting and exceeding the highest testing standards. It also provides further assurance and confidence in data results as well as validated methods, staff training procedures, equipment calibration and successful participation in proficiency testing/interlaboratory comparisons.

Starting out with 1500 square feet of laboratory space, within the last year Encore Labs has doubled its work area. In order to meet the growing demand of the cannabis testing industry, they have added plans to once again double in size by the end of 2019, as well as open a second laboratory by the end of 2020.

Gas Chromatography/Infrared Spectroscopy: A Tool For the Analysis of Organic Compounds in Cannabis

By John F. Schneider

2 Comments

Editor’s Note: The author will be teaching a 1/2 day short course on this topic at PITTCON in Philadelphia in March 2019.

The combination of gas chromatography and infrared spectroscopy (GC/IR) is a powerful tool for the characterization of compounds in complex mixtures. ^(1-5) Gas chromatography with mass spectroscopy detection (GC/MS) is a similar technique, but GC/MS is a destructive technique that tears apart the sample molecules during the ionization process and then these fragments are used to characterize the molecule. In GC/IR the molecules are not destroyed but the IR light produced by molecular vibrations are used to characterize the molecule. IR spectrum yields information about the whole molecule which allows the characterization of specific isomers and functional groups. GC/IR is complementary to GC/MS and the combination results in a powerful tool for the analytical chemist.

A good example of the utility of GC/IR vs GC/MS is the characterization of stereo isomers. Stereo isomers are mirror images such as a left hand and a right hand. In nature, stereo isomers are very important as one isomers will be more active then its mirror image. Stereo isomers are critical to medicinal application of cannabis and also a factor in the flavor components of cannabis.

GC/MS is good at identifying basic structure, where GC/IR can identify subtle differences in structure. GC/MS could identify a hand, GC/IR could tell you if it is a left hand or right hand. GC/MS can identify a general class of compounds, GC/IR can identify the specific isomer present.

Why GC/IR?

Gas chromatography interfaced with infrared detection (GC/IR), combines the separation ability of GC and the structural information from IR spectroscopy. GC/IR gives the analyst the ability to obtain information complementary to GC/MS. GC/IR gives the analyst the power to perform functional group detection and differentiate between similar molecular isomers that is difficult with GC/MS. Isomer specificity can be very important in flavor and medical applications.

Gas chromatography with mass spectrometry detection (GC/MS) is the state-of-the-art method for the identification of unknown compounds. GC/MS, however, is not infallible and many compounds are difficult to identify with 100 % certainty. The problem with GC/MS is that it is a destructive method that tears apart a molecule. In infrared spectrometry (IR), molecular identification is based upon the IR absorptions of the whole molecule. This technique allows differentiation among isomers and yields information about functional groups and the position of such groups in a molecule. GC/IR complements the information obtained by GC/MS.

Interfaces

Initial attempts to couple GC with IR were made using high capacity GC columns and stopped flow techniques. As GC columns and IR technology advanced, the GC/IR method became more applicable. The advent of fused silica capillary GC columns and the availability of Fourier transform infrared spectrometry made GC/IR available commercially in several forms. GC/IR using a flow cell to capture the IR spectrum in real time is known as the “Light Pipe”. This is the most common form of GC/IR and the easiest to use. GC/IR can also be done by capturing or “trapping” the analytes of interest eluting from a GC and then measuring the IR spectrum. This can be done by cryogenically trapping the analyte in the solid phase. A third possibility is to trap the analyte in a matrix of inert material causing “Matrix Isolation” of the analyte followed by measuring the IR spectrum.

Infrared Spectroscopy

The physical state of the sample has a large effect upon the IR spectrum produced. Molecular interactions (especially hydrogen bonding) broadens absorption peaks. Solid and liquid samples produce IR spectra with broadened peaks that loses much of the potential information obtained in the spectra. Surrounding the sample molecule with gas molecules or in an inert matrix greatly sharpens the peaks in the spectrum, revealing more of the information and producing a “cleaner” spectrum. These spectra lend themselves better to computer searches of spectral libraries similar to the computer searching done in mass spectroscopy. IR spectral computer searching requires the standard spectra in the library be of the same physical state as the sample. So, a spectrum taken in a gaseous state should be searched against a library of spectra of standards in the gaseous state.

IR of various phases:

Liquid Phase – Molecular interactions broaden absorption peaks.
Solid Phase – Molecular interactions broaden absorption peaks.
Gas Phase – Lack of molecular interactions sharpen absorption peaks.
Matrix Isolation – Lack of molecular interactions sharpen absorption peaks.

IR Chromatograms

GC/IR yields chromatograms of infrared absorbance over time. These can be total infrared absorbance which is similar to the total ion chromatogram (TIC) in GC/MS or the infrared absorbance over a narrow band or bands analogous to selected ion chromatogram. This is a very powerful ability, because it gives the user the ability to focus on selected functional groups in a mixture of compounds.

Conclusion

Gas chromatography with infrared detection is a powerful tool for the elucidation of the structure of organic compounds in a mixture. It is complementary to GC/MS and is used to identify specific isomers and congeners of organic compounds. This method is greatly needed in the Cannabis industry to monitor the compounds that determine the flavor and the medicinal value of its products.

GW Pharma’s Enormous Price for Epidiolex

By Marguerite Arnold

5 Comments

In a fascinating early August conference call with Seeking Alpha, British-based GW Pharmaceuticals finally revealed their retail price point for CBD-based drug, Epidiolex, as it goes into distribution in the U.S.

The drug is designed for the treatment of certain kinds of childhood epilepsy – although not all kinds. Also notable of course, is that GW Pharma’s “other” drug for treatment of resistant epilepsy failed in late stage trials in Eastern Europe earlier this year. It also knocked off 5% of the price of the company’s stock.The company is estimating it has a potential patient pool of between 25,000- 30,000 patients in the U.S.

British Advocacy Over Access And Pricing

The ineffectiveness of GW Pharma’s drugs for many patients (along with the cost charged for them) was responsible for pre-empting the entire access discussion in the UK this year. The mother of an epileptic British child tried to import a personal store of cannabis oil (produced by Canadian LP Tilray) only to have it confiscated at the airport this summer. Her son ended up in the hospital shortly thereafter.

The national uproar this caused pushed forward the country’s new medical cannabis policy– indeed drug rescheduling is due to go into effect in October. Conveniently, right as Epidiolex goes on sale in the U.S. (where cannabis remains a Schedule I drug).

The company is estimating it has a potential patient pool of between 25,000- 30,000 patients in the U.S.

Price Tags and Politics

What is the price of Epidiolex? $32,500 per patient, per year. If that sounds high, the company insists it is pricing the drug to be “in line” with other drugs for this segment of the market.

The majority of this cost will not be picked up by private health insurers but rather the federal governmentActually, according to industry analysis, this is about 70% more than the price of one comparable drug (Onfi), and slightly more expensive than Banzel, the two competing (non-cannabinoid based) medications now available in the U.S. for this market.

Here is the other (widely unreported) kicker. The majority of this cost will not be picked up by private health insurers but rather the federal government, which is also not negotiating with GW Pharma about that high price (unlike for example what is going on in Europe and the German bid).

Why the difference?

Two reasons. The first is that Epidiolex has obtained “orphan drug” status (a medication for a disease that affects fewer than 200,000 patients in the U.S.) The second is that the majority of the insurance that will be picking up this tab is Medicaid. The patient pool will be unable to afford this. As a result, the bulk of the money will remit not from private insurance companies but rather federal taxpayers. And, unlike in say, Germany, none of this is pre-negotiated in bulk.

Co-payments are expected to range from $5 to $200 per month per patient after insurance (read: the government) picks up the tab. This essentially means that the company plans to base participation at first at least on a sliding scale, highly subsidized by a government that has yet to reschedule cannabis from a Schedule I in the U.S.

Creating, in other words, a new monopoly position for GW Pharmaceuticals in North America.

A Hypocrisy Both Patients And The Industry Should Fight

The sordid, underhanded politicking that has created this canna monster is hardly surprising given the current political environment in both the U.S. and the U.K. right now. The people who benefit the most from this development are not patients, or even everyday shareholders, not to mention the burgeoning legitimate North American cannabis industry, but in fact highly placed politicians (like British Prime Minister Theresa May). Philip May, the PM’s husband’s firm is the majority shareholder in GW Pharma. Her former drugs minister (with a strong stand against medical cannabis) is married to the managing director of British Sugar, the company that grows GW Pharma’s cannabis stock domestically.

So far, despite a domestic outcry over this in the UK (including rescheduling), there has been no political backlash in the United States over this announcement. Why not?

Look To Europe For A More Competitive Medical Market

This kind of pricing strategy is also a complete no go in just about every other market – including medical-only markets where GW Pharma already has a footprint.

For example, German health insurers are already complaining about this kind of pricing strategy for cannabis (see the Cannabis Report from one of the country’s largest insurers TK – out earlier this year). And this in an environment where the government, in fact, does negotiate a bulk rate for most of the drugs in the market. Currently most German cannabis patients are being given dronabinol, a synthetic form of THC which costs far less.

On top of this, there are also moves afoot by the German government to begin to bring the costs of medical cannabis and medicines down, dramatically. And this too will impact the market – not only in Europe, but hopefully spark a debate in every country where prices are also too high.

The currently pending German cultivation bid for medical cannabis has already set an informal “reference” price of at most 7 euros a gram (and probably will see bid competitors come in at under half that). In other words, the government wholesale price of raw, unprocessed cannabis flower if not lightly processed cannabis oil is expected to be somewhere in the neighbourhood of 3-4 euros per gram come early next year. If not, as some expect, potentially even lower than that.

Processed Cannabis Medicine vs. Whole Plant Treatment

The debate that is really raging, beyond pricing, is whether unprocessed cannabis and cannabis oil is actually “medicine.” At the moment, the status quo in the U.S. is that it is not.

GW Pharmaceuticals, in other words, a British company importing a CBD-based derivative, is the only real “medical cannabis” company in the country, per the FDA. Everyone else, at least according to this logic, is placed in the “recreational camp.” And further, hampered still, with a lack of rescheduling, that affects everyone.

If that is not an organizing issue for the American cannabis industry, still struggling with the many issues inherent in the status quo (from insurance coverage and banking to national distribution across state lines) leading up to the midterms, nothing will be.

The UK Steps Up On Medical Cannabis Use

By Marguerite Arnold

No Comments

British Home Secretary Sajid Javid appears to have become the most high ranking cannabis advocate in the British government. He has just launched a review into medicinal uses of cannabis in the UK. However, this dramatic change in policy has only come after a series of high profile campaigns and escalating battles for access waged by patients and their families against a government which has remained stubbornly intransigent in the face of growing evidence of medical efficacy and reform elsewhere. In fact, the cannabis “Battle of Britain” has come to resemble the contretemps in Israel over the same issue four years ago that led to a national review of medical use and greater patient access.

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

It is expected that this recent turn of events will open better access for more British medical users. The fact that the timing of all of this comes as GW Pharma has received the right to distribute Epidiolex in the U.S. as the first FDA-approved cannabis-based medicine is not only part of the irony but the underlying problematic politics surrounding all of this. Starting with the timing of who has access to what, and under what circumstances. As it stands, Epidiolex is also the only cannabis-based drug now eligible in the United States for healthcare coverage. The rest of the market is so-far excluded from it. Unlike, it should be pointed out the situation in the UK, the rest of the Commonwealth, and of course, the EU. Starting with Germany.

A Major Win for Patients

Celebrate one for Alfie! Alfie Dingley that is – the British 6 year old with epilepsy who has become one of the most well-known faces of medical justice for cannabis users in the UK. Dingley and his parents waged a battle since last fall over his right to consume low THC cannabis oil that allows him to manage his epilepsy. He has just been granted an emergency license to import the oil from the Netherlands.

But this is also a victory for Billy Caldwell, the twelve-year-old who ended up in emergency care in hospital recently after his medical oil (from Canada) was confiscated at the border. Video of border control agents at Heathrow Airport removing the oil from the Caldwells caused a national outcry in the UK. Caldwell’s mother, Charlotte, has also waged a high profile battle for access, including at the doors of the hospital her son was admitted to last week. She has also started her own CBD company named after her son.

Like the rest of Europe, which the UK still technically is part of until Brexit, the focus here has very much been on medical use.And of course, this new indication in change of policy is seen as a major victory if not step forward for literally thousands if not millions of Britains who suffer from chronic conditions that are still drug resistant (like Epilepsy but not limited to the same.)

As he addressed the House of Commons on the issue of medicinal cannabis use, Javid said “It has become clear to me since becoming home secretary that the position that we find ourselves in currently is not satisfactory…I have now come to the conclusion that it is time to review the scheduling of cannabis.” As in the US, cannabis is still considered a Schedule I drug in the UK – with supposedly no medical efficacy. This new development clearly challenges that scheduling – but where and how?

Recreational Is Still Not On The Table

Like the rest of Europe, which the UK still technically is part of until Brexit, the focus here has very much been on medical use. This is for several reasons, including a much better and more inclusive public health system – despite imminent fears about the longevity of the British National Health Service (NHS).

In the UK, however, further reform is not likely to move fast. Unlike anywhere else, cannabis production is essentially limited to one company – GW Pharmaceuticals – who themselves have high standing political connections that continue to oppose reform. This is not based on science but rather profit. Despite the fact that the British Isles are the largest exporter of medical cannabinoid pharmaceuticals in the world, British patients are still largely excluded from access. The only reason that these children and their parents were able to pierce the wall of privilege and profit that has driven the debate here since the late 90’s is that GW Pharmaceutical’s cannabinoid concoctions do not work on this kind of epilepsy. Plus the failure of a recent trial of their new drug (shamefully in Europe, not even conducted in the UK).

As a result, GW Pharmaceuticals and the well placed scions of British society who have profited directly and personally from this situation have little choice but to back down – but not by much. As soon as Javid announced his intention to do a review of British policy, former Tory (conservative) leader Lord William Hague called for full legalization. An initiative that as of June 19 was rejected by the government.

Is Medical Finally About To Get Its Due?

In Europe, politically, the frustration is clearly growing. And much like in the United States circa 2012, activists and advocates realize that medical access is the first step towards full reform. However here there is a marked difference to what is going on in both the U.S. and Canada. And in turn, this may bring a long overdue focus on the medical issue that has continually been obscured and overlooked by the industry itself as soon as recreational seems it is in reach.

When real and regulated medical markets are allowed to flourish, the first beneficiaries are both children and women, not middle-aged men. That is clearly the face of the “average” German patient now that the data of the first year has come in. It is also likely to be the case of the British patient as well as Europeans across the continent.In Europe, politically, the frustration is clearly growing

Further, as cannabis has become more of an accepted treatment, this is in turn forcing governments (and even the industry itself) to begin, for the first time, to consider funding widespread trials – and of the raw plant itself along with extracts and other forms the drug can be consumed in.

What does this really herald, in fact then besides relief for chronically ill patients? The first widespread scientific inquiry into the efficacy of cannabinoids outside of Israel.

And that too, is cause for celebration. Congrats Alfie and Billie! And all the people who helped move the issue forward.
