In a press release published last week, Shimadzu Scientific Instruments announced a partnership with MoCann Testing, a division of EKG Labs. MoCann Testing is the first state-certified medical cannabis testing lab in Missori.
It sounds like the partnership involves Shimadzu supplying MoCann with instruments and supporting their testing efforts with training, method development and maintenance, though the press release does not mention any details.
“We are excited to support MoCann’s mission to help individuals across the state of Missouri have access to safe medical marijuana through accurate sample testing and quality results,” says Bob Clifford, Ph.D., general manager of marketing at Shimadzu. “Because selecting the right analytical solutions is a critical investment, we provide more than just advanced instrumentation and software. We assist with method development, instrument training and maintenance that keep systems operating at the highest level.”
MoCann Testing is certified by Missouri, accredited to ISO 17025 and they offer the full gamut of testing services for growers and manufacturers in Missouri.
It was 1996. I was four years old. California Proposition 215 passed and for the first time, legal medical cannabis became available. I don’t remember it honestly, but that moment triggered a reckoning of outdated and ineffective efforts to control cannabis, which continues on November 3rd.
The moment in 1996 created for me and my generation of millennials a new, decriminalized lens for which to view cannabis and its potential. In my lifetime, from first experimenting with cannabis after high school and then earning my PhD in plant biochemistry, advancing cannabis research, to starting an agtech company dedicated to the genetic improvement of cannabis, we continue this march toward legalization. But another march hasn’t started yet.
The cannabis we consume today is still largely the same (albeit more potent today) as the cannabis that was legalized in 1996. There’s been little advancement in our scientific understanding of the plant. This can and should change. I believe the future and legitimacy of the cannabis crop in the medical field and in farmers’ fields is on the ballot this November.
In 33 states, medical cannabis is currently legal and in eleven of those, including my home states of Nevada and Washington, legalized adult-use recreational cannabis is generating millions in tax revenue every month. But compared to every other commercial crop, cannabis is still decades behind.
We are seeing a glacial cadence with cannabis research. As voters in five more states consider this November whether to legalize cannabis, that same tipping point we reached in 1996 comes closer to being triggered for cannabis research.
Here’s what cannabis scientists, like me, face as we work to apply real scientific methods to the long-neglected crop: I published one of the most cited papers on cannabis research last year, titled, Gene Networks Underlying Cannabinoid and Terpenoid Accumulation in Cannabis. But, as per university policy, we were unable to touch the plant during any of our research. We could not study the physical cannabis plant, extracts or any other substantive physical properties from the plant on campus or as a representative of the university. Instead we studied cannabis DNA processed through a third-party. Funding for the research came from private donors who were required to be unassociated with the cannabis industry.
While we were conducting our heavily restricted, bootstrapped cannabis research, the university lab in the next building over was experimenting with less restrictions on mice using other drugs: cocaine, opioids and amphetamines. (Quick note, marijuana is listed as more dangerous than cocaine, which is a Schedule II drug.)
I get it. Due to the federal prohibition on cannabis as a heavily regulated Schedule I drug, universities cannot fund research without the risk of losing all of their federal funding. While the USDA does not support research and SBIR grants are all but impossible, one government agency does allow research, from cannabis grown only in Mississippi. It’s the Drug Enforcement Agency (DEA) and any research conducted using its crop is as ineffective as you’re imagining. Relevant research is likely impossible using the crop which dates back to a 1970’s strain with a potency that’s about 30 percent of today’s commercial cannabis offerings.
To change this anti-research climate, do what those in California did with Prop 215 in 1996. Vote.
Vote for legalization of cannabis if you’re in those five states where legalization is on the ballot; that’s Arizona, New Jersey, Montana, South Dakota and Mississippi. The more states that align with cannabis legalization, the stronger the case becomes for the federal government to reschedule the drug from a Schedule I controlled substance. Currently cannabis is listed as a Schedule I alongside heroin. The DEA claims cannabis has no currently accepted medical use and a high potential for abuse. Both are not true, just listen to the scientists.
Those outside of the five states putting cannabis on the ballot can still play a role in creating a Congress that is more receptive to cannabis reform. This Congress is the oldest, one of the most conservative and least effective in our country’s history. Younger, more progressive representation will increase our odds of advancing cannabis research.
Cannabis holds far too much possibility for us to allow it to be an unstudied “ditch weed.” THC and CBD are just two of nearly 500 compounds found in cannabis which, when scientifically scrutinized will harvest – I believe – vast medicinal and commercial benefits and the tax windfalls that accompany both. But first you have to vote.
If cannabis and your representatives are not on the ballot, do something millennials have built somewhat of a reputation for failing to do; pick up a phone and call your current representative. Tell them cannabis deserves scientific attention and investment. There’s too much potential in the cannabis plant to wait any longer.
According to a press release, Shimadzu Scientific Instruments and Front Range Biosciences (FRB) announced a partnership where they will establish the FRB Hemp Science Center of Excellence. The center will focus on genetics, biobanking, breeding and analysis, all with Shimadzu instrumentation. The center will host scientists performing chemical and genetic analytical research to “support the development of new hemp varieties for the production of cannabinoids, terpenoids and other compounds for medical and wellness applications; lipid, wax and protein ingredients for food and cosmetics applications; and fiber for industrial applications.”
Located at FRB’s new headquarters in Boulder, CO, the new center will allow for collaborative efforts between researchers from the public and private sectors like academic, nonprofit and government agencies. The center will expand FRB’s collaboration with the University of Colorado at Boulder. Researchers at other institutions can apply for grants to support students, postdoctoral candidates and other researchers at the new center.
Dr. Jonathan Vaught, CEO of FRB, says they’re honored to work with Shimadzu and their instrumentation. “Front Range Biosciences is honored to partner with the world-class team at Shimadzu. Combining their innovative and proven cannabis and hemp analytical instrumentation solutions with our next-generation breeding program, we will be well positioned to continue advancing the industry with data-driven science so we can harness the incredible potential of this versatile plant for therapeutic, wellness, nutrition and industrial applications,” says Dr. Vaught. “We are confident that with Shimadzu’s cutting-edge technology, we will be able to drive forward-thinking solutions in this growing industry to better serve farmers, producers and consumers.”
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.
According to a press release, the University of Colorado at Boulder is offering a new course focused on cannabis science through the Continuing Education program at the university during the upcoming Summer and Fall semesters.
The class is called Modern Cannabis Science and will involve a lot of genetic research. The course is sponsored by the Agricultural Genomics Foundation, a non-profit dedicated to scientific research and education in cannabis. In the press release, they describe the course as meant for students who are well informed, but “seek a deeper appreciation of scientific advancements in cannabis genetics.”
Here’s a snapshot of what students can expect to learn from it:
In Modern Cannabis Science, we will explore the range of Cannabis research currently available covering topics such as evolutionary history and global distribution, sex chromosomes, genetic contribution to chemotype, and analyses to aid law enforcement and forensic investigations. We will examine how genetic data allow us to understand relationships between strains and common categories in the Cannabis genus, and why this is important for breeding, policy-making, and medical purposes.
The press release suggests students who enroll can expect to use this knowledge in the cannabis industry. “For example, a budtender will be able to more accurately recommend strains to users,” reads the press release. “Similarly, medical personnel will more fully understand the relationship between strains, the compounds they produce, and how to properly advise Cannabis patients.”
Emerald Scientific now offers their customers PerkinElmer products, like their QSight® 420 Triple Quad system LC/MS, the Titan MPS™ Microwave Sample Preparation System, the Clarus® SQ 8 Gas Chromatograph/Mass Spectrometer (GC/MS) and the Flexar™ High-Performance Liquid Chromatography (HPLC) system. This partnership also allows Emerald Scientific customers to utilize the PerkinElmer analytical methods and standard operating procedures (SOPs) for cannabis and hemp testing. That includes SOPs for things like sample preparation, acquisition methods and consumable use. They’ll also be able to shop for lab products like PerkinElmer’s chromatography columns, vials and sample prep products.
According to Greg Sears, vice president and general manager, Food and Organic Mass Spectrometry at PerkinElmer, the cannabis testing market is exploding and this will help labs get their equipment and necessities all in the same place. “With the cannabis and hemp markets continuing to grow rapidly and regulations strengthening, labs increasingly need streamlined access to best-in-class, user-friendly testing solutions geared toward the unique requirements of the industry,” says Sears. ““This collaboration with Emerald Scientific brings together leading cannabis analysis offerings in one place to help labs start up and expand more efficiently. In addition, we can build on the work we have done with Emerald around testing standardization which is important for the science of the industry.”
Kirsten Blake, Vice President of Emerald Scientific, says they are really excited about the partnership. “As regulations become more challenging, laboratory competition intensifies, and the science of the industry receives increasing focus, it is essential to align with organizations dedicated to improving both the quality and throughput of analytics,” says Blake. “After working with PerkinElmer to inform, educate, and advance the cannabis science industry around best practices, we see them as the industry leader for providing analytical instrumentation, methods and SOP’s. By adding their complementary solutions to our existing portfolio, we can now deliver complete packaged analytical solutions to the cannabis and hemp industries.”
For those who have been watching (if not in the thick of) the drama over Israeli medical cannabis export rights, this latest development was not only inevitable but overdue. Israel’s parliament unanimously approved the legislation on Christmas Day (along with Thailand). Less than a month later, the cabinet concurred.
That means that export rights are now actionable law.
Beyond this final passage into reality, export rights have been at the forefront of a global drama on cannabis- most recently in this part of the world, as a specific chip in political dealmaking between U.S. President and Israel’s Prime Minister, Benjamin Netanyahu since the former entered office. This go around at least.
The political bargaining that even allowed Israel’s medical program to flourish and get funding from its earliest days (including of the U.S. federal government kind) of course, is nothing new.
Pioneers Of The Cannabis Industry
Hard as it is to believe, most of what is widely known and easily digitally shared (including on social media) about cannabis (as a plant, let alone distinctions between cannabinoids) is information created during this last four to eight-year period (certainly since 2010). This has been driven by reform, and a birth of wider education about medical and recreational cannabis plus the cannabis industry and broader lifestyle press. And most of what is credible out there, no matter who claims credit today, has an Israeli origin, and of the medical kind.
Add this history of scientific research and insight to the philosophy of a nation driven by entrepreneurial zest, and say no more.
Now that Israel can begin to export its cannabis, the interesting thing to see is whether cannatech will in the end, be more valuable than individual strains themselves. The pick axe in this particular “green gold rush?”
For now, of course, all bets are off, even on the cultivation front. Because, no matter what else it is, it is well timed, globally, to give even the Israeli medical production market a big green shot in the arm.
Germany and Europe Beckons
The change in the law in Israel also comes as those who made first qualifying round in the German cultivation bid are getting prequalification letters, although this time, no firms, anywhere, have issued press releases about their finalist round status.
And here is the other issue to consider: While the bid itself does not have anything to do with import capability, new Israeli game in town is, in itself, a big game changer for anyone whose hat was thrown into the coalitions who applied for the pending cultivation license. Why? Until they deliver their first crops grown auf Deutschland, firms have to deliver from somewhere. And this being Germany, the import destination has to be from a place where the plant is federally legal. Israel becomes another option in a market so far dominated by Dutch and Canadian firms.
Can you smell new bid lawsuits also, if this scenario has not already been addressed by BfArM? The history of cannabinoids in Germany in general (historically as well as recently) is fraught already. This pending challenge, should it come, will be laden with symbology modern Germany will do everything to avoid provoking.
Beyond the soap opera that the bid has turned into in Germany (the ultimate test case for cultivation and insurance-backed medical and industry acceptance across the rest of the EU essentially), there are of course, other markets beckoning. This includes all of Eastern Europe and much of the EU. This includes France and the UK immediately.
In other words, no matter what the longer-term impacts will be, this well timed, politically astute Israeli decision is coming at the beginning of what is going to be, as everyone is clearly seeing at the end of January, a momentous and earth-shaking year not only for Europe, but globally.
And that is big business for a little country with an eye on the export game.
I was wrong. And that’s a good thing! Based on all available data, I assumed that evaporating ethanol from a cannabis oil/ethanol solution would result in terpene loss. As it turns out, it doesn’t. There are so many beliefs and assumptions about cannabis: Cannabis cures cancer!1 Smoking cannabis causes cancer!2 Sativas help you sleep; Indicas make you creative!3,4 CBD is not psychoactive!5 But are these ‘facts’ backed by science? Have they been experimentally tested and validated?
I postulated a theory, designed experiments to validate it and evaluated the results. Simply putting “cannabis backed by science” on your label does not solve the problem. Science is not a marketing term. It’s not even a fixed term. The practice of science is multifaceted and sometimes confusing. It evolved from the traditional model of Inductivism, where observations are used in an iterative process to refine a law/theory that can generalize such observations.6 Closely related is Empiricism, which posits that knowledge can only come from observation. Rationalism, on the other hand, believes that certain truths can be directly grasped by one’s intellect.7 In the last century, the definition of science was changed from the method by which we study something, such as Inductivism or Rationalism, and refocused on the way we explain phenomena. It states that a theory should be considered scientific if, and only if, it is falsifiable.8 All that means is that not the way we study something is what makes it scientific, but the way we explain it.
I wonder how can we use empirical observations and rational deliberations to solve the questions surrounding cannabis? And more importantly, how can we form scientific theories that are falsifiable? Cannabis, the plant, the drug, has long been withheld from society by its legal status. As a result, much of what we know, in fact, the entire industry has thrived in the shadows away from rigorous research. It’s time for this to change. I am particularly concerned by the lack of fundamental research in the field. I am not even talking about large questions, like the potential medical benefit of the plant and its constituents. Those are for later. I’m talking about fundamental, mundane questions like how many lumens per square centimetre does the plant need for optimal THC production? What are the kinetics of cannabis extraction in different solvents? What are the thermodynamics of decarboxylation? Where do major cannabinoids differ or align in terms of water solubility and viscosity?
The lack of knowledge and data in the cannabis field puts us in the precarious position of potentially chasing the wrong goals, not to mention wasting enormous amounts of time and money. Here’s a recent example drawn from personal experience:Certainly, I cannot be the only one who has made an incorrect assumption based on anecdotes and incomplete data?
Some of the most common steps in cannabis oil production involve ethanol solutions. Ethanol is commonly removed from extraction material under reduced pressure and elevated heat in a rotary evaporator. I expected that this process would endanger the terpenes in the oil – a key component of product quality. My theory was that volatile terpenes9 would be lost in the rotary evaporator during ethanol10 removal. The close values of vapor pressure for terpenes and ethanol make this a reasonably assumed possibility.11 In the summer of 2018, I finally got the chance to test it. I designed experiments at different temperatures and pressures, neat and in solution, to quantify the terpene lost in ethanol evaporation. I also considered real life conditions and limitations of cannabis oil manufacturers. After all the experiments were done, the results unequivocally showed that terpenes do not evaporate in a rotary evaporator when ethanol is removed from cannabis extracts.12 As it turns out, I was wrong.
We, as an industry, need to start putting money and effort into fundamental cannabis research programs. But, at least I ran the experiments! I postulated a theory, designed experiments to validate it and evaluated the results. At this point, and only this point, can I conclude anything about my hypothesis, even if that is that my working theory needs to be revised. Certainly, I cannot be the only one who has made an incorrect assumption based on anecdotes and incomplete data?
There is a particular danger when using incomplete data to form conclusions. There are many striking examples in the medical literature and even the casual observer might know them. The case of hormone replacement therapy for menopause and the associated risks of cardiovascular diseases showed how observational studies and well-designed clinical trials can lead to contradicting results.13 In the thirties of the last century, lobotomy became a cure-all technique for mental health issues.14 Dr. Moniz even won the Nobel Prize in Medicine for it.15 And it must come as no surprise when WIRED states “that one generation’s Nobel Prize-winning cure is another generation’s worst nightmare.”16 And with today’s knowledge is impossible to consider mercury as a treatment for syphilis, but that is exactly what it was used as for many centuries.17 All those examples, but the last one in particular should “be a good example of the weight of tradition or habit in the medical practice, […] of the necessity and the difficulties to evaluate the treatments without error.”18 There is the danger that we as cannabis professionals fall into the same trap and believe the old stories and become dogmatic about cannabis’ potential.
We, as an industry, need to start putting money and effort into fundamental cannabis research programs. That might be by sponsoring academic research,19 building in-house research divisions,20 or even building research networks.21 I fully believe in the need for fundamental cannabis research, even the non-sexy aspects.22 Therefore, I set up just that: an independent research laboratory, focused on fundamental cannabis research where we can test our assumptions and validate our theories. Although, I alone cannot do it all. I likely will be wrong somewhere (again). So, please join me in this effort. Let’s make sure cannabis science progresses.

Much has been made about the plummeting market value of cannabis grown outdoors in Oregon. This certainly isn’t a reflection of the product quality within the marketplace, but more closely attributable to the oversaturation of producers in this space. This phenomenon has similarities to that of ‘Tulip Mania’ within the Dutch Golden Age, whereby tulip bulbs were highly coveted assets one day, and almost worthless the next. During times like these, it is very easy for industry professionals to become disheartened; however, from a scientific perspective, this current era in Oregon represents a tremendous opportunity for discovery and fundamental research.
As we have mentioned in previous presentations and commentaries, our research group is interested in exploring the breadth of chemical constituents expressed in cannabis to discover novel molecules, to ultimately develop targeted therapies for a wide range of illnesses. Intrinsically, this research has significant societal implications, in addition to the potential financial benefits that can result from scientific discovery and the development of intellectual property. While conducting our experiments out of Arlington, Texas, where the study of cannabis is highly restricted, we have resorted to the closet genetic relative of cannabis, hops (Humulus lupulus), as a surrogate model of many of our experiments (Leghissa et al., 2018a). In doing so, we have developed a number of unique methods for the characterization of various cannabinoids and their metabolites (Leghissa et al., 2018b; Leghissa et al., 2018c). These experiments have been interesting and insightful; however, they pale in comparison to the research that could be done if we had unimpeded access to diverse strains of cannabis, as are present in Oregon. For example, gas chromatography-vacuum ultraviolet spectroscopy (GC-VUV) is a relatively new tool that has recently been proven to be an analytical powerhouse for the differentiation of various classes of terpene molecules (Qiu et al., 2017). In Arlington, TX, we have three such GC-VUV instruments at our disposal, more than any other research institution in the world, but we do not have access to appropriate samples for application of this technology. Similarly, on-line supercritical fluid extraction – supercritical fluid chromatography – mass spectrometry (SFE-SFC-MS) is another capability currently almost unique to our research group. Such an instrument exhibits extreme sensitivity, supports in situ extraction and analysis, and has a wide application range for potential determination of terpenes, cannabinoids, pesticides and other chemical compounds of interest on a single analytical platform. Efforts are needed to explore the power and use of this technology, but they are impeded based on current regulations.
Circling back, let’s consider the opportunities that lie within the abundance of available outdoor-grown cannabis in Oregon. Cannabis is extremely responsive to environmental conditions (i.e., lighting, water quality, nutrients, exposure to pest, etc.) with respect to cannabinoid and terpene expression. As such, outdoor-grown cannabis, despite the reduced market value, is incredibly unique from indoor-grown cannabis in terms of the spectrum of light to which it is exposed. Indoor lighting technologies have come a long way; full-spectrum LED systems can closely emulate the spectral distribution of photon usage in plants, also known as the McCree curve. Nonetheless, this is emulation and nothing is ever quite like the real thing (i.e., the Sun). This is to say that indoor lighting can certainly produce highly potent cannabis, which exhibits an incredibly robust cannabinoid/terpene profile; however, one also has to imagine that such lighting technologies are still missing numerous spectral wavelengths that, in a nascent field of study, could be triggering the expression of unknown molecules with unknown physiological functions in the human body. Herein lies the opportunity. If we can tap into the inherently collaborative nature of the cannabis industry, we can start analyzing unique plants, having been grown in unique environments, using unique instruments in a facilitative setting, to ultimately discover the medicine of the future.

The variety of terms used to describe cannabis are as diverse as the potentials of the plant itself – as well as the opinions of its proper nomenclature. A quick web search came up with a number of articles about how we should refer to cannabis, and opinions can be just as annoying and stinging as mosquitoes in the Everglades at the peak of season. Each of these words has an origin with which, having all the facts, you might not choose to align yourself. Words matter, and whether born from racism, xenophobia, or just plain ignorance, one will never go wrong following one simple piece of advice: “Never use a word or a phrase unless you know its meaning.” That said, it is not my intention here to add another opinion, but rather to present the topic from a different vantage. I’ll leave it up to you to decide whether or not it is worth your while to learn what you are saying, and in so doing, empower yourself to consider your audience as you consider your slang, just as you would with any other word.
The legalized cannabis industry has opened a plethora of professional opportunities. Thoughtfully considered, these opportunities can lead to new heights of professional accomplishment and financial earning capability. For those with the good fortune to have such opportunity in legalized cannabis, congratulations! You are a member of a very small group of pioneers who have the potential to shape an entire industry (remember that what Henry Ford did by creating the assembly line brought benefit, not just to the automotive industry, but to all industry.)
In this industry we are not just creating medical cannabis dispensaries, cultivation and processing facilities, we are creating new ideas and platforms for compliance, security, financial planning, quality assurance, botany, agriculture, sustainability, packaging, retail, inventory control, human capital – the list is as endless as the imagination – with the potential to influence capacity in every aspect of all types of industry, around the world. In the course of your career as a cannabis professional you will have a chance to interact with legal and healthcare professionals, legislators, regulators and investors. You may attend high profile events, hobnob with those who inspire social change and exchange dialog with thought leaders from all walks of life. As you represent your particular cannabis company, you will recognize that you also represent yourself, and in that very recognition will your thoughtfully chosen vernacular reveal your personal level of professionalism, eloquence and dignity; and irrespective of what, or from whom, any opinion originates, these core values are irreplaceable. Simply put, adults speak like adults.
A colleague reflected that we are not winning a long and drawn out struggle to divest ourselves from outdated prohibitions against the use of medical cannabis because of the words we are using, but because of education. While I agree with that assessment, the use of slang in professional discourse has a tendency to discredit the speaker and narrow the audience receptive to his message. As the scientific community and cannabis industry continues to re-educate society, our efforts will be bolstered by reaching as broad an audience as possible. Education presented professionally, eloquently, and with maturity engenders respect, goodwill and understanding. And that makes for fertile ground upon which to plant new ideas.
