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.

What’s Going Down In The Danish Cannabis Market?

By Marguerite Arnold

1 Comment

Despite the fact that the Danes are going to do something that is still verboten in Germany and many other European locales (namely allow a recreational trial), the overall bloom is off the first heady days of the cannabis rose here in Denmark.

Medical sales have stalled of late because of both supply (and in part CannTrust problems) and of course price in a market with a lot of cultivation enthusiasm, but also one which still imports its medical cannabis (although domestic production is coming online soon).

This is even more interesting of course given some ideas floating in the current Euro cannosphere – namely that Canadian funded, Danish based cultivators are or were planning on importing to both Germany and Poland this fall. In other words, low sales at home for expensive product that can be bought for less at the revived Christiana marketplace are not a market entry strategy that brings ballast to balance sheets. And while the rec market is coming (obviously), the trial is in early days yet.

Further, while the German market certainly presents an opportunity for higher priced cannabis coming out of Denmark (for now), that also will not last. And is certainly not the case in Poland.

For that reason, it is clear there is at least temporary trouble brewing in what some initially thought was going to be a European-based cannabis paradise. But that too, is so 2018.

A Few Numbers

The medical trial in Denmark is now entering the beginning of its third year as of 2020. There are, according to official estimates just over 4,000 legal patients. 34 companies have permits to cultivate cannabis, including all the usual suspects – starting with Canopy Growth, Aurora, Aphria, ICC (Wayland) and The Green Organic Dutchman, plus of course all the indie locals.

Put this in perspective and is it really any wonder why Aurora also just recently announced the halting of partly built construction in both Denmark and Canada this month?

Especially with problems in Poland, slower than expected legal sales in Germany and of course the disaster that is still the UK, this newest setback for the company is also not exactly unexpected. The only cannabis company, European or not, who benefitted from the recent NHS pivot on medical cannabinoids was the home-based GW Pharmaceuticals, albeit at lower negotiated prices as the total pool of patients is now increased with the new NICE guidelines.

Given all of these headwinds, even with a few export possibilities, the Danish market that supposedly offered a promised respite from the problems of the German one (certainly on the cultivation front), has run into a similar problem at point of prescription and sales.

Even Danish patient number growth is anaemic compared to Deutschland – which is, by all reports, not even close to considering a recreational trial in Berlin, Bremen or any other jurisdiction which has suggested the same.

With bulk, high-grade production coming online, there is clearly going to be a regulated cannabis market in Denmark. How the decisions about who will qualify for medical will be made in the future is another question. And one that certainly the larger producers at least, are responding to in kind.

The Winds of Change

Given the amount of compliant cannabis now in the pipeline for the continent (and not just domestically) it will be interesting to see how 2020 shapes up. However, no matter how still sluggish the numbers, another domestic cannabis market has begun to come into its own as the continent moves forward on the issue generally.

The Women in Cannabis Study: A Q&A with Jennifer Whetzel

By Aaron G. Biros

1 Comment

Ladyjane Branding and Wolfe Research & Consulting are leading an ambitious study to explore and document the experiences of women working in the cannabis market. Women in Cannabis: A Living History officially kicks off on December 10^th at the National Women of Cannabis Conference.

Jennifer Whetzel, founder of LadyJane Branding and founder of the Women in Cannabis Study

Jennifer Whetzel, founder of Ladyjane Branding, says this is an opportunity for women to tell their stories about their experience working in the cannabis industry. Women can participate in the study by going to womenincannabis.study and sign up to take the survey. You can also sign up to be a sponsor or partner of the study at that website. Sponsors will get access to content like press releases and the opportunity to incorporate the study’s findings in their messaging. We invite our readers to participate, sponsor, partner, share and encourage friends to take the survey.

With beta testing starting the week of November 18^th, we caught up with Jennifer Whetzel to talk about why she decided to start this project, what they expect to learn from it and what the future may hold for professional women in the cannabis industry.

Cannabis Industry Journal: Can you tell us a bit about your background and how you came into the cannabis industry?

Jennifer Whetzel: My entrance into the cannabis industry was certainly a culmination of my personal experience and professional journey.

After moving to Maine, I became a medical user to ease symptoms of an immune and an auto-immune disorder. When I sought out treatment for PTSD, I found that a combination of cannabis, therapy, meditation and brain retraining was the most helpful and healthy solution.

This course of treatment for PTSD was life-changing as it allowed me to resolve symptoms from all of my medical issues, and I wanted to find a way to give back to the community that supported me. I had been working in marketing for over 25 years and realized I had quite the diverse professional background. My experience included retail merchandising and operations, public relations on a military base, research design and strategy for ad agencies, new product development and launch for animal health companies, and experiential marketing strategy and design. I’ve been lucky enough to work with small companies and Fortune 500’s which has led to finding solutions in unexpected places.

When pairing my knowledge and skills with the cannabis community, I realized I could make an impact by advising new entrepreneurs who needed help making their brands stand out. That’s how Ladyjane Branding was born.

CIJ: Can you give us an overview of the Women in Cannabis Study?

Jennifer: The Women in Cannabis study aims to understand how women are faring in the cannabis industry and whether we are doing enough to support women, their careers and their professional goals. It’s well documented that women in corporate America do not have the same opportunities for career advancement as men, holding fewer executive or board positions, having fewer opportunities for mentorship, sponsorship and career progression.

The study is comprehensive, with more than 80 quantitative questions along with qualitative telephone and video interviews of female-identifying professionals working in the cannabis industry – whether they are involved with cannabis, CBD or hemp. Through monthly infographics, video summaries, quarterly in-depth themed reports and a comprehensive year-end report, we will be telling the stories of women’s professional experiences in cannabis with the goal of transforming the industry into one where women can succeed and thrive.

Painting a picture of the women in cannabis, and understanding them as a group, we look at demographics to explore their diversity and reveal whether personality differences may affect their experiences, as well as experience with stigmas regarding cannabis use and working in the industry.

To understand professional trajectories and roadblocks on a path to success, we dive into work history, reasons for entering the cannabis space and the barriers they have faced on their journey. We explore opportunities for mentorship, support and leadership, the types of harassment, discrimination and disrespect they’ve experienced and how that may have impeded their careers.

We’d like to understand how (or whether) women find balance in their personal and professional lives, what sacrifices they’ve had to make for a career in cannabis, as well as best practices for women to foster success.

CIJ: Why did you decide to take on this endeavor and lead the work on this study?

Jennifer: While there are numerous studies looking at how women fare in corporate America, we found that there’s a lack of a recent and comprehensive deep dive into this topic specifically for cannabis. As an emerging industry, we have a unique opportunity to make valuable recommendations to potentially increase inclusivity for women in this early stage of industry culture before it becomes too entrenched. Our goal is to ensure we have the hard numbers to document a baseline now, then follow-up over time to understand how the industry changes.

By surveying and speaking to women in the industry, and understanding where strengths and weaknesses in the industry lie, we can make recommendations to improve the lived experience for women working in this industry.

The only way to make improvements to a system is to understand it.

CIJ: How do you think we can create a more inclusive industry?

Jennifer: I think it begins with an understanding of where we are starting – we don’t know what we don’t know. Being in the cannabis industry, we often hear the argument that anecdotes are not data. Just like we need the scientific data to prove efficacy for medicine, we need the data that shows the hard numbers about diversity and inclusion, the stigma and shame of cannabis use or working in this industry, about sexual harassment, disrespect and bullying.

This study is about generating information and creating knowledge on this issue so we can determine the education, policies, procedures and actionable recommendations that can help make the industry a welcoming space for everyone.

One of the best ways to create a more inclusive industry is through education.

CIJ: What hurdles do women face in the cannabis industry? How is that different from other, more established industries?

Jennifer: As we review research results from more established industries, it seems clear that women face similar hurdles in cannabis. Various studies have shown that working women are faced with unequal pay, fewer opportunities for mentorship or sponsorship, as well as discrimination and disrespect. The issues for female entrepreneurs are even greater as women are significantly less likely to receive venture capital funding, which certainly speaks to experience in the cannabis industry.

Because there’s little data specifically focused on the cannabis industry, we are just guessing. This study will provide us those answers.

CIJ: Looking ahead, how do you think women will fare in the evolution of the cannabis market?

Jennifer: I’d like to think that if we are all purposeful and intentional about creating an equitable, inclusive, and representational industry, that women will fare significantly better than they have in other industries typically dominated by men. If that can happen, everyone will feel welcome and respected, and it will no longer be surprising news when a woman is promoted to CEO or becomes a successful founder.

Agilent Partners with LSSU on Cannabis Chemistry & Research

By Aaron G. Biros

No Comments

Back in August, Lake Superior State University (LSSU) announced the formation of a strategic partnership with Agilent Technologies to “facilitate education and research in cannabis chemistry and analysis.” The university formed the LSSU Cannabis Center of Excellence (CoE), which is sponsored by Agilent. The facility, powered by top-of-the-line Agilent instrumentation, is designed for research and education in cannabis science, according to a press release.

The LSSU Cannabis CoE will help train undergraduate students in the field of cannabis science and analytical chemistry. “The focus of the new LSSU Cannabis CoE will be training undergraduate students as job-ready chemists, experienced in multi-million-dollar instrumentation and modern techniques,” reads the press release. “Students will be using Agilent’s preeminent scientific instruments in their coursework and in faculty-mentored undergraduate research.”

The facility has over $2 million dollars of Agilent instruments including their UHPLC-MS/MS, UHPLC-TOF, GC-MS/MS, LC-DAD, GC/MS, GC-FID/ECD, ICP-MS and MP-AES. Those instruments are housed in a 2600 square-foot facility in the Crawford Hall of Science. In February earlier this year, LSSU launched the very first program for undergraduate students focused completely on cannabis chemistry. With the new facility and all the technology that comes with it, they hope to develop a leading training center for chemists in the cannabis space.

Dr. Steve Johnson, Dean of the College of Science and the Environment at LSSU, says making this kind of instrumentation available to undergraduate studies is a game changer. “The LSSU Cannabis Center of Excellence, Sponsored by Agilent was created to provide a platform for our students to be at the forefront of the cannabis analytics industry,” says Dr. Johnson. “The instrumentation available is rarely paralleled at other undergraduate institutions. The focus of the cannabis program is to provide our graduates with the analytical skills necessary to move successfully into the cannabis industry.”

Storm Shriver is the Laboratory Director at Unitech Laboratories, a cannabis testing lab in Michigan, and sounds eager to work with students in the program. “I was very excited to learn about your degree offerings as there is a definite shortage of chemists who have experience with data analysis and operation of the analytical equipment required for the analysis of cannabis,” says Shriver. “I am running into this now as I begin hiring and scouting for qualified individuals. I am definitely interested in a summer internship program with my laboratory.”

LSSU hopes the new facility and program will help lead the way for more innovation in cannabis science and research. For more information, visit LSSU.edu.

FDA Public Hearing On Hemp: What You Need To Know

By Aaron G. Biros

2 Comments

Folks from around the country and the world tuned into the U.S. Food & Drug Administration (FDA) website as they held a public hearing on Friday, May 31. Manufacturers and suppliers asked the FDA to regulate CBD like food or dietary supplements, while the FDA seemed to want more evidence on the safety of CBD products before giving the greenlight.

Background On The Hearing

For the uninitiated, after President Trump signed the Farm Bill into law back in December 2018, Scott Gottlieb, now former director of the FDA, issued a statement the same day the Farm Bill passed, clarifying the FDA’s regulatory authority. In the statement, Gottlieb explained that Congress preserved the FDA’s authority to regulate products containing cannabis and its constituents under the Federal Food, Drug, and Cosmetic Act (FD&C Act).

In April 2019, around the same time he resigned from the FDA, Gottlieb issued another statement, acknowledging the quickly growing industry throughout the country and total lack of federal regulatory guidance. This time around, Gottlieb laid out a handful of steps that the FDA plans on taking to address regulations around hemp and cannabidiol (CBD). Those included scheduling the public hearing for May 31, where written and oral public comments were submitted by stakeholders, sharing “their experiences and challenges with these products [hemp and CBD products], including information and views related to product safety.”

That statement also announced the formation of an internal agency working group to “explore potential pathways for dietary supplements and/or conventional foods containing CBD to be lawfully marketed; including a consideration of what statutory or regulatory changes might be needed and what the impact of such marketing would be on the public health.”

Fast-forward to May 31, the day of the public hearing, and all eyes in the industry focused on what all these stakeholders had to say to the FDA about CBD. The day started off with about two hours of oral comments, each speaker had roughly two minutes to deliver their thoughts.

Karen Howard, CEO of the Organic and Natural Health Association, speaks about the quality of CBD products

Oral Comments

Industry stakeholders representing cannabis businesses sang much of the same tune, clamoring for wise regulations on safety, testing, banking and interstate commerce, among other standards. NCIA Policy Director Andrew Kline’s comments included running through five major positions of the industry trade organization representing CBD companies. Those included recommending the FDA act quickly in setting up regulations, stressing the massive economic impact of the industry, saying that CBD products are generally safe, clamoring for voluntary, consensus-based standards and informing consumers of any potential risks. “The bottom line is this – an overwhelming preponderance of evidence indicates that cannabis and cannabis-derived compounds present minimal health and safety concerns,” Kline told the folks at the FDA. “Time is of the essence. Hemp-derived CBD products are in very high consumer demand and the industry is eagerly awaiting FDA’s regulatory framework for these products. We strongly recommend that FDA act quickly to clarify the regulatory environment because there is significant confusion in the market.”

Anna Williams, representing the American Association for Laboratory Accreditation (A2LA), stressed the importance of testing for contaminants and adulterants as well as advocating for national standards on lab testing, instead of the state-by-state network of different standards.

Patients & Public Safety

After industry stakeholders had their chance to speak, the FDA allowed a group of advocacy organizations representing patients time to speak. That included representatives for the Alzheimer’s Association and the American Epilepsy Society, both of which were hesitant to throw their full support behind CBD as medicine. Kevin Chapman with the American Epilepsy Society said he wants to see clear warning labels, testing standards, more clinical trials and more studies before the group is ready to form a position on using CBD as medicine. Keith Fargo with the Alzheimer’s Association supports clinical trials to study it more, but thinks CBD is risky for patients without serious evidence of efficacy. A representative from the Tuberous Sclerosis Alliance also echoed similar concerns. They want to see labeling of drug interactions on labels of CBD products.

After those comments, some organizations had the chance to speak followed by comments from retailers and distributors. Patrick Bird, owner of PMB BioTek Consulting, spoke on behalf of AOAC International, where he primarily discussed public safety. He said they want cannabis products to be regulated with food safety in mind, asking for FSMA to apply to hemp products. They want to adequately ensure product safety with things like mandating HACCP plans, recall readiness, saying hemp products should be treated just like food products.

Retailers & Distributors

Peter Matz, representing the Food Marketing Institute, the trade association for the supermarket industry, said that regulatory ambiguity is a serious issue that needs addressing. “There is mass confusion in the marketplace for the public, suppliers, retailers and state regulators,” says Matz. “Demand for CBD products in human and animal use is growing rapidly. ¼ of American have already tried it. We are fielding questions from companies seeking clarity regarding the current federal regulatory framework.” He added, what many others also mentioned, that the FDA needs to move swiftly to provide a pathway to regulation.

State Regulators

Next on the docket came presentations from state government entities, including state departments of agriculture, followed by healthcare professionals. The state regulators that spoke mentioned a lot about food safety, standards, testing regulations, GMPs and things like that to protect consumer safety. “Currently states are struggling with the lack of sound scientific research available in CBD and long-term health impacts,” said Pam Miles, representing the Virginia Department of Agriculture.

One interesting aspect on their talks however was telling the FDA just how large their markets have gotten already and how they need guidance on how to regulate markets in their own states. Joseph Reardon, with the North Carolina Department of Agriculture, said they already have about 600 farmers growing hemp and thousands of processors working with the product in their state. “We urge the FDA to resolve the statutory issues improperly establish a legal pathway for CBD products to enter the market place,” Reardon commented. He also asked that the FDA extend the written comment period from July to August. “We are simply looking for a regulatory framework on the extraction, production and reconstitution of CBD or cannabinoid related products.”

Healthcare & Research

Healthcare providers, and physician testimony also echoed a lot of the same concerns, including the lack of research done, concerns about effects on at-risk populations and concerns about use as ingredients in dietary supplements and food. Some of the presentations also highlighted the room for nefarious activity in an unregulated marketplace. Some went as far as to mention cases where they found CBD vape juices with DXM in it (the active ingredient in cough syrup), CBD products found to contain THC, as well as synthetic cannabinoids responsible for drug overdose deaths. Some advocates in the hemp and CBD community have equated these arguments similar to reefer madness.

The major takeaway from this hearing is that everyone wants to see more data. Researchers and healthcare providers want to study the efficacy of CBD used in medicine, regulators want public safety information, patient advocates want to see data about effects on at-risk populations, trade organizations want data to back up label claims and the FDA wants to see just how safe CBD really is.

Clinical Trials Commence for CBD Pet Products

By Aaron G. Biros

2 Comments

Products using hemp-derived cannabidiol (CBD) designed for pets is not a new concept; Companies have been marketing CBD pet products for quite some time now, making their way into pet stores across the United States. Some pet owners have embraced the trend, using CBD oil to calm pets down, help alleviate joint pain as well as inflammation, while others are understandingly skeptical when it comes to using novel remedies for their furry friends.

Researchers at the University of Pennsylvania’s School of Veterinary Medicine hope to find some answers to those questions, particularly regarding the efficacy of using CBD remedies for dogs. According to a press release, a team of researchers at University of Pennsylvania’s Veterinary Clinical Investigations Center will perform the first major double-blind clinical trial to study the effectiveness of CBD in treating joint immobility in dogs. The trial will be led by principal investigator Dr. Kimberly Agnello.

According to the press release, this is the largest trial for cannabinoid therapy in pets so far. The trial will include use of the CBD-infused pet product, Therabis’ “Mobility.” Therabis is a subsidiary of Dixie Brands, Inc., a large cannabis infused products company in markets across the United States. Here are some of the details on the clinical trial, shared through the press release:

Dogs known to be suffering from inflammation secondary to osteoarthritis will be studied to determine whether those who receive the Therabis supplement achieve better outcomes than untreated dogs. One group of dogs will receive the formula for a proprietary veterinarian-specific formula Therabis product; a second group will receive Cannabidiol alone which previous studies have shown may have benefit in osteoarthritic dogs; a control group will receive a placebo. Study designers are targeting inclusion of up to 20 dogs in each group. The design of this study will provide valuable data defining the synergistic potential of the additional ingredients in the Therabis formula.

According to Dr. Stephen M. Katz, co-founder of Therabis, they think the data from the trials will show a positive outcome for dogs using their products. “We are honored to have a Therabis product selected by the world-renowned experts at Penn Vet for their first major study of the effects of natural hemp oil to reduce joint pain in dogs,” Says Katz. “Our experience in my clinic has shown that cannabidiol (CBD) is an effective treatment in reducing inflammatory response. We have a passion for improving dogs’ quality of life, and we look forward to learning all we can about therapeutic methods to achieve this.”

The results from this clinical trial, to be published in an academic journal upon conclusion of the study, should be of great interest to the hemp industry. Brightfield Group estimates that the CBD-infused pet products market is a $199 million industry, expected to grow up to $1.16 billion by 2020.
