Is the Cannabis Industry Sitting On An Untouched Gold Mine Of Innovation?

By Pam Chmiel

Universities across the country are working in all areas of research and development to advance cannabis cultivation, medicine, drug delivery and technology. But these innovations are collecting dust because the universities are not in the business of commercializing products in the marketplace.

In 1980, the federal government passed a law that said universities that receive federal funding, which most of them do, will have the option to own whatever intellectual property or invention they develop from that federal funding. Initially, universities resisted the idea feeling they were selling their souls to the private sector and corporate America. But opinions have changed, and the marriage between universities and industries is a common and rewarding business strategy for both sides.

I interviewed Lance Anderson, a partner at the law firm Dickinson Wright who is uniquely positioned to play matchmaker to research universities, entrepreneurs and VCs to help them uncover cannabis innovations and create partnerships. Lance is also educated in life sciences, including proprietary plants, genetics and plant-derived products, and served as in-house counsel and lead IP attorney for a large public research university system and an early-stage venture capital company.

Pam Chmiel: What led you to play matchmaker to universities and cannabis businesses?

Lance Anderson: I learned that universities are interested in commercially benefiting from some of their innovations when I worked in the technology commercialization office at Texas Tech University right out of law school.

The concept of “technology transfer for commercialization” already exists in universities and presents a vast opportunity for cannabis businesses to commercialize their innovations.

Lance Anderson, an attorney at Dickinson Wright

“Technology Transfer” agreements refer to moving technology, knowledge or innovations from one organization, such as a research university, to another entity, such as a cannabis company, through licensing agreements that grant permission to use intellectual property (IP), patents or proprietary technology for commercial purposes.

Even though legalization is sweeping the country, I’m finding that academic institutions and their administrators are concerned they will lose all federal funding and are hesitant to take the chance on a cannabis research project. They are still getting comfortable with the opportunities to work with the industry, and the farm bill act of 2018 gave them the push to do so.

And why not tap into these universities, which receive millions and millions of dollars in funding? You’re not out a lot if you properly structure your relationship with them. You do not have to pay them millions and millions of dollars to get this technology. Knowing what the university wants and how to structure that relationship is key.

Pam: What are some of the benefits a business can gain by forging a partnership with a university?

Lance:

Cannabis companies benefit by gaining access to cutting-edge research, expertise and resources that can accelerate and elevate their product development and market entry.
The association with academic institutions can help build trust among consumers, investors, and lawmakers.
Working with university research students may create a pipeline of qualified employees who may want to work for the company.
Submitting a joint proposal with a university seeking government grants may lead to additional funding for the research project.

Pam: What types of partnerships do you currently see in development?

Lance: Pharmaceutical companies have collaborated with research universities for years on drug development and undoubtedly have their eye on the cannabis industry. Federal agencies like the USDA lean on academic partnerships to develop unique plant traits to improve crop production. You’ve got institutions developing new mind-blowing genetics, like polyploid species, that allow you to fine-tune the plant traits you’re interested in. There are always advances going on.

Clemson and Cornell Universities are leading the charge in cultivation by partnering with farms to develop techniques to grow better crops and increase profitability. And interestingly, many of the land grant institutions that receive federal grants, like Mississippi State, Michigan State and Texas A&M, are now diving into plant trait development. And it’s not unrealistic to think they will transition into plant-touching technologies ripe for the cannabis industry to come in and run with it from there.

“Researchers are now getting more access to cannabis strains that are more like what we’re seeing on the market, but it’s still not where we need to be”

But the research desperately needed to move the industry forward is medical research because lawmakers want proof that cannabis has medicinal benefits before they are confident in pushing for legalization. Unfortunately, the US government has been part of the problem in making it hard to conduct research, whether clinical trials, clinical research or simple preclinical studies on cannabis. Until recently, the University of Mississippi was the only university allowed to cultivate for research. So the researchers are now getting more access to cannabis strains that are more like what we’re seeing on the market, but it’s still not where we need to be. Not even close.

Academic partnerships are not a new concept, but the cannabis industry has yet to embrace it fully. Opportunities are beginning to develop where government agencies will participate and or fund the work in cannabis from the university standpoint. The National Institute of Health has a program that’s getting kicked off for cannabis research. And they all understand and recognize that the fact we don’t have enough clinical data available is a major hindrance to the advancement of this industry.

Pam: What is legally involved in a technology transfer partnership?

Lance: Collaboration between cannabis companies and research universities can take various forms, such as research partnerships, sponsored research agreements, joint ventures, or licensing arrangements. The specific model depends on the goals, resources, and intellectual property involved in the collaboration. An attorney can structure an agreement in a manner that lets everyone slowly advance into the relationship and get satisfied with the milestones they want and at which point this thing begins to take shape.

Cannabis businesses are no strangers to utilizing multiple entities in their corporate structuring. They may have a holding company that owns the real estate, a staffing company that manages the HR for the flower-touching operations, and another that holds the intellectual property. You’re seeing an entire industry familiar with IP licensing for the first time in a long time, and universities want in by licensing their intellectual property.

The university may require a licensee to have a product in the marketplace and a first sale within two years. So that introduces the concept of perishable intellectual property rights where you can default or don’t meet the licensing requirements. That perishable concept sometimes makes it hard to raise money because the investors prefer a guarantee that you have the license and will not default.

The takeaway is universities are thirsty for partnering and looking for strategic initiatives. Universities have access to patient populations, and the cannabis industry has the business know-how to take their innovations to market. It will take some culturing of both sides to understand the opportunities. But once everyone’s on the same page, the deals will look like the licenses and joint venture deals we see now with multi-state operators.

Pam: Lance, do you have any closing thoughts for our audience?

Lance: I’ve thought about this potential synergy for years as I’ve watched these two areas I practice in often. Academic partnerships are the catalyst to move the cannabis industry forward and are right in front of us. The time is now, and I’d love to be there.

Abstract

The public has readily embraced cannabidiol (CBD) in countless unregulated products that benefit from commercial promotion without FDA oversight, who recently concluded: “that a new regulatory pathway for CBD is needed that balances individuals’ desire for access to CBD products w/ the regulatory oversight is needed to manage risks.”¹ The reported antimicrobial properties of CBD combined with the recent proliferation of cannabinoid-containing products marketed to women for intimate care led us to explore the impact on the sentinel lactobacilli species associated with a healthy reproductive tract. Except for lubricants and tampons, the FDA regulates intimate care products as cosmetics. Even non-cannabis serums, washes, and suppositories are not required to be tested for their effect on the reproductive microbiota. We aimed to investigate the utility of easy-to-use, inexpensive in vitro assays for testing exogenous cannabis products on reproductive microbiota. In vitro assays can provide important evidence-based data to inform both manufacturers choosing both an active cannabinoid ingredient source as well as excipient chemicals and consumers in the absence of safety or quality data. In simple, straightforward exposure studies, we examined the antimicrobial activity of CBD and cannabigerol (CBG) on the most dominant vaginal lactobacilli species, L. crispatus, associated with good health.

Introduction

The testing of readily available products containing cannabinoids, predominately CBD following the widespread legalization of hemp by the 2018 US Farm Bill, is not required beyond ensuring THC content is below 0.3%. Therefore, basic information on safety, quality, antimicrobial activity, bioavailability, and dosing is unavailable and undocumented. The situation is further complicated by the complex chemoprofiles of cannabis extracts based on the cultivar, the extraction methods and subsequent cleanup, and other chemical excipients in the formulation. The FDA has finalized guidance on quality considerations for clinical research for the development of cannabis and cannabis-containing drugs intended for human use.

One approach to backfilling non-existent safety and quality data for cannabinoid active ingredients and those products made from them is to apply or devise assays that can provide relevant toxicity data in an in vitrosystem. Farha et al. (2020) reported that seven cannabinoids are potent antibiotics, including CBD and synthetic CBG. CBG inhibited the growth of gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), but not gram-negative bacteria unless their outer membrane was permeabilized (Farha et al. 2020). In addition, several volatile terpenes, the main constituents of essential oils extracted from Cannabis sativa L., also have potent antibiotic activity against gram-positive bacteria (Iseppi et al. 2019). We have previously written about the risks associated with disrupting the healthy microbiome of gram-positive vaginal bacterial species leading to dysbiosis (Orser 2022) and its further health complications.

Several successful approaches to assessing the toxicity of CBD have already been reported including human cell culture work by Torres et al. (2022) who showed that pure CBD has a repeatable impact on cell viability, but that hemp-derived finished CBD products had variable impact. Cultured human cell viability experiments demonstrated similar potencies across three different hemp-derived CBD products in the microgram per milliliter [mg/mL] range with increased viability at lower doses [2-4 mg/mL] and decreasing cell viability above 6 mg/mL (Torres et al. 2022). In the same study, the authors demonstrated that the presence of terpenes, specifically b-caryophyllene, in hemp extraction matrices also impacted cell viability.

Neswell, a cannabis therapeutics company in Israel, demonstrated through the application of their in vitroneutrophil cell line that cannabis extracts have inherent immune response biodiversity, suggesting that the choice of a cannabis source should be based on its function rather than on its chemoprofile (https://www.neswell.net). Inflammatory cytokine levels in inflamed peripheral blood mononuclear cells (PB_MC) showed a 10-fold difference across hemp extract products containing unidentified terpenes in suppressing the inflammatory cytokine, TNFa (Torres et al. 2022). The influence of CBD concentration on inflammatory cytokine production was previously reported by Vuolo et al. (2015) and Jiang et al. (2022).

Materials & Methods

Chemicals and Products Tested

THC-free, 99% pure CBD and CBG isolates were purchased from Open Book extracts in North Carolina (openbookextracts.com). All other chemicals including erythromycin (EM), and growth media were obtained from Sigma-Aldrich (St. Louis MO). Specific reagents in the qPCR kits were assembled in-house at MatMaCorp Inc. (Lincoln NE).

Monitoring Cell Viability: OD600nm and plating

Individual frozen glycerin stocks of L. crispatus HM103 from BEI Resources Repository served as inoculum to streak on a sterile MRS agar plate and incubated anaerobically at 37⁰C for 24-48 h until individual colony growth was observed. Single colonies were used to inoculate MRS broth and incubated for 24-48 h at 37⁰C which served as the inoculum for exposure to test products. Exposed cultures and all control cultures were incubated at 37⁰C for 48 h with OD₆₀₀ readings taken at time zero, +24 h, and +48 h using disposable cuvettes in a standard spectrophotometer. The products were also plated onto MRS agar plates to evaluate inherent contaminants that could affect turbidity values.

Molecular Analysis by qPCR

DNA isolation from bacterial cultures was done using the MatMaCorp (Lincoln, NE) StickE Tissue DNA Isolation kit modified for bacteria as per manufacturer instructions. Briefly, a lysis buffer is applied to the sample followed by a heating step, and a binding buffer is added, thus allowing DNA from the solution to bind to the matrix of the StickE column. The column was washed prior to eluting the purified DNA. Per manufacturer instructions, 10 µL of isolated DNA was used as a template for genetic analysis in a Lacto-TM assay (MatMaCorp). The assay is a customized TaqMan-based detection assay that is conducted using a four-channel fluorescence detection platform, the Solas 8 (MatMaCorp). The assay was designed to detect the unique 16S-rRNA DNA sequence for L. crispatus. Briefly, the assay is a probe-based method that begins with hybridizing the custom-designed probes with their desired nucleic acid target found in the sample. Once hybridized, detection takes place from the fluorescently labeled primer. The target has been assigned a channelon the Solas 8 and is detected independently.

Calling the Results

The calling algorithm uses first-order kinetics reaction properties (inflection point detection) in combinationwith a measure of the closeness of the signals associated with a specific target. Various indicators are tracked during the reactions to perform an on-the-fly analysis. The analysis is then consolidated by a measure of the similarity between the fluorescence signals at the end of the run. Aggregating values from the similarity measure, the end gain and the inflection point detection allow the Solas 8 software to make the call at the end of the run without having to compare a results library of known sample targets.

Results

Exposure of L. crispatus

Anaerobically grown cultures of L. crispatus were exposed to either CBD isolate or CBG isolate at each of two concentrations [5 mg/mL] and [10 mg/mL] with all appropriate controls. All treatment groups were evaluated by qPCR, turbidity at OD₆₀₀, and plate counts.

Molecular Analysis via qPCR

These data show the specificity of the Solas8 testing for evaluating these products, as a molecular-level screening is not influenced by test product solubility, opacity, or non-specific contamination present in some of the tested products that can interfere with optical density measurements.

Growth Monitoring

Turbidity monitoring, albeit non-specific, confirmed the species-specific qPCR findings, that is no inhibition for the two cannabinoid isolates evaluated (Fig. 2).

Conclusions

In this limited in vitro study using a sentinel lactobacilli response, we have shown that 99% pure CBD and CBG isolates were not inhibitory at the two doses evaluated by complementary observations following turbidity, plating, and by qPCR. Limitations in this study prevent definitive conclusions regarding what individual or combination of cannabinoids or other cannabis secondary metabolites are inhibitory in vivo to dominant lactobacilli species in the reproductive tract. These limitations include commercial product testing without knowledge of excipients or impact on the bioavailability of any active cannabinoid ingredients. In addition, dose-response curves were not generated and exposure under micro-aerobic conditions was not carried out.

Cannabidiol’s potential as an antimicrobial agent may be limited by its extremely low solubility in water and a propensity to stick to spurious proteins limiting systemic distribution in the body as a therapeutic. Interpreting microbiome study findings to human health outcomes will require multi-disciplinary corresponding clinical data findings of disease diagnosis, processes, and treatment within populations. Nonetheless, this nascent translational research opportunity is vast with the promise of benefiting patient outcomes (Wensel et al. 2022).

Health Canada released a scientific review report on products containing cannabis, specifically containing 98% or greater CBD and less than 1% of THC (Health Canada 2022) while the FDA just concluded that there are no existing guidelines applicable for recommending safety and quality guidelines to manage risk for CBD products (U.S. FDA 2023). The Health Canada committee unanimously agreed that short-term use of CBD is safe at 20 mg per day up to a maximum dose of 200 mg per day and that packaging should include both dosing instructions and potential side effects. The Committee did not address the antimicrobial potential of CBD or CBG formulations or specifically vulvar or vaginally administered cannabinoids. There is clearly more basic physiological research needed on the impact of self-administration of CBD preparations based on the route of exposure.

Affinity Bio Partners on Working with Zelira Therapeutics to Complete Enrolment for Diabetic Nerve Pain Drug Trial

It’s an exciting time in the medical cannabis community as Zelira, a global leader in the research, development and commercialization of clinically validated cannabinoid medicines, and Affinity Bio Partners, a leading, global clinical research organization, have completed enrollment for a diabetic nerve pain drug trial. The Institutional Review Board (IRB)-approved head-to-head trial read out is expected in Q1 of 2023. Two years in the making, the study’s clinical management, clinical trial site monitoring, subject recruitment, regulatory submissions and review and query of data have brought us to a pivotal point that could pave the way for how future clinical studies are conducted in the medical cannabis community. As someone who comes from traditional pharma and biotechnology industries, heading up a clinical study in the medical cannabis realm has been a significantly different, eye-opening and informative experience that reinforces the dire need for mainstream, medical cannabis education.

Difficulties of Enrolling Subjects in a Cannabinoid-Based Clinical Study

There are a number of reasons that enrolling a cannabinoid study is very challenging. One of the biggest challenges to overcome is creating educational clinical study material that will be approved by the Institutional Review Board while educating potential subjects who are interested in enrolling. In other words, one must fully understand the regulatory landscape that they’re operating in, and we all know cannabis is a tricky one, while still educating potential subjects.

When screening subjects, it is important to be able to thoroughly share facts regarding cannabinoids, terpenes and other ingredients utilized in the study material. Also, sharing information on the endocannabinoid system is important, and a must for subjects to understand. In addition, it is integral to share and contrast between the traditional pharmaceutical products versus the cannabinoid study drug. Meaning, most subjects understand and are familiar with pills and other treatments approved in the traditional FDA regulated pharmaceutical space. Therefore, you must ensure that you create a bridge between a study’s educational materials and the lack of mainstream education about cannabinoid-based therapies.

The Impact This Will Have on Future Cannabinoid-Based Clinical Studies

There is a lot of hope that by working on a study of this magnitude, that we will pave the way for many more companies to bravely enter the clinical trial space as it pertains to medical cannabis. Everything that is being performed in this Zelira clinical study is in accordance with all applicable laws and regulations. The team is utilizing an electronic patient reported outcomes and electronic data capture system to receive data directly from the clinical trial sites as they are seeing the patients. As more patients, groups, communities and organizations learn about this, we hope that other large players in the cannabis industry invest their money wisely and perform clinical studies on their formulated products. Companies are unable to make claims of product safety and efficacy legally without these clinical studies. As we approach 2023, it is time for us as an industry to begin forecasting future clinical studies that will help power the therapeutic benefits this plant has to offer in responsible, controlled settings.

Study Finds Only 7% of CBD Brands Conduct Proper Lab Testing

By Cannabis Industry Journal Staff

2 Comments

Leafreport released the findings from their expansive CBD testing study that revealed some pretty alarming results. According to their study, only 7% of CBD brands they sampled actually conduct legitimate contamination testing for pesticides, heavy metals and microbial contamination.

Leafreport is an Israeli company founded in 2019 that does product reviews, independent testing and provides educational resources for consumers. The company produces studies on CBD products in the market and reports their results on its website. Back in 2020, the watchdog company conducted independent lab testing on 22 different CBD-infused beverages and found a lot of inconsistencies with the actual amount of CBD found in the beverage and what the product’s label claimed.

In this latest study, finalized in late May of 2022, the consumer advocacy group found a lot of inconsistencies throughout the CBD market. For their study, they reviewed 4,384 products from 188 brands, with the goal of looking at overall transparency in the CBD products market. Judging by the results they share, the CBD market is unsurprisingly not very transparent.

Here are some highlights from this most recent study:

20% of the brands reviewed didn’t carry out any purity tests to check for the presence of microbes, pesticides, or heavy metals. In 2021, 25% of the brands Leafreport reviewed didn’t carry out any purity tests.
42% of brands test almost all of their products for potency (90%-100% accurate) and share their third-party lab results with consumers — the same as in 2021.
Only 12% of brands had all their products fall within acceptable potency variance limits.
88% of brands that tested their products for potency had at least one product test beyond the 10% variance for potency, in comparison to 84% in 2021.
28% of brands didn’t carry out any testing at all for pesticides (such as glyphosate), 26% didn’t test for the presence of any heavy metals (such as arsenic), and 24% didn’t test for microbes (like bacteria).
Two brands carried out no lab testing at all for either purity or potency, compared to 3 brands in 2021.

Research Suggests Cannabis Could Help Treat Covid-19

By Cannabis Industry Journal Staff

No Comments

One study published in the Journal of Natural Products two weeks ago proposes using the cannabinoid CBDA in conjunction with vaccines to prevent SARS-CoV-2 (Covid-19) infection. The study was conducted in a lab and says that cannabinoid acids (CBGA, THCA-A, CBDA, etc.) can bind to the SARS-CoV-2 spike protein, blocking cell entry and effectively prevent infection.

Another study published in Science Advances claims cannabidiol (CBD) inhibits SARS-CoV-2 replication and helps prevent infection by inducing endoplasmic reticulum stress response and innate immune responses. The study was conducted in cells and mice, but also had groups of human patients that tested positive for Covid-19 less after taking CBD. “In matched groups of human patients from the National COVID Cohort Collaborative, CBD (100 mg/ml oral solution per medical records) had a significant negative association with positive SARS-CoV-2 tests,” reads the abstract.

Two studies in Israel, one proof-of-concept study and one early-stage clinical trial, have just launched examining the effects of CBD on patients already infected with Covid-19.

The structure of cannabidiol (CBD), one of 400 active compounds found in cannabis.

All of this research already underway does not mean that cannabis prevents Covid-19. In fact, one clinical trial in Brazil that has finished, found no evidence that CBD helped patients with mild Covid-19. Published in the Cannabis and Cannabinoid Research Journal, patients with mild Covid-19 received 300 mg of CBD for 14 days or a placebo. The study suggests that clinical trials should be conducted for the effects of CBD on patients with severe Covid-19, not just mild symptoms.

The clinical trial in Israel that is trying to study the effects of CBD on patients with severe Covid-19 is having trouble finding participants because the newer Omicron variant mainly produces only mild to moderate symptoms.

It is far too early to tell if any of these studies will show evidence of cannabis treating Covid-19, let alone if they mean cannabis products can be used as a treatment or preventative for Covid-19. However, the research is significant and we should keep an eye on any developments that come from those studies.

Statnews.com said it best:

“The latest hubbub is an example of both the promise of cannabinoids — components of cannabis — as potential therapies, but also the hype around them, which can far outpace the evidence that they work. It’s left researchers and consumer advocates scrambling to warn people that patients shouldn’t be turning to over-the-counter products or recreational marijuana in hopes that it might protect them from Covid-19.”

Is There a Place for Perpetual Tele-Monitoring and Clinical Research in the Medical Cannabis Industry?

By Christina DiArcangelo

No Comments

As we continue to witness and experience the medical cannabis industry grow and mature, many of us are wondering where the head-to-head clinical studies are, and why aren’t there more clinical research studies taking place?

Cannabis products created with the intention for medicinal use often state that their formulations and products stack up against traditional pharmaceutical treatments. However, without a substantial number of clinical studies being performed, it’s difficult to truthfully make such a claim. It’s one thing to share testimonials from people who use particular products and report what their experiences were like. However, to go head-to-head in a controlled environment where factors such as underlying conditions, height, weight, medication, lifestyle and nutrition habits are taken into account to accurately compare the efficacy of a traditional pharmaceutical product versus a cannabis-derived product are two completely different things.

The Need for More Capital

Wouldn’t you agree that if a company is having tremendous success with a particular product, that they’d reinvest capital into a true clinical study to have data to support their marketing efforts? Investing into proper studies would not only benefit a company working hard to earn market share, it would benefit those who are relying on a particular product to regain a quality life. As we’ve learned over the years from numerous scientists and researchers digging into the cannabis plant at a more granular level, there’s much more to the medicinal benefits than meets the eye. Discovering new information about how cannabinoids such as CBG and CBN combined with CBD and certain terpenes can create specific effects has helped make a greater impact on the medical cannabis community. Bringing these powerful blends of anti-inflammatory, cannabis-derived compounds and other immune boosting nutraceuticals to head-to-head clinical studies could be a huge step forward towards further legitimizing the healing effects that cannabis has to offer.

Measuring Efficacy Goes Beyond COAs & Product Reviews

Determining the efficacy of medical cannabis products should be viewed in the same light as traditional pharmaceutical products. Traditional clinical studies are designed with an Institutional Review Board (IRB) approval, subject recruitment, electronic data capture as well as electronic patient reported outcomes. Some companies within the cannabis space have made attempts to conduct surveys with measuring efficacy in mind, but using outdated survey technology that hasn’t been validated only leads to insufficient data collection.

There is nothing wrong with adult-use cannabis. However, for the medical cannabis space to be taken more seriously, it is time for organizations to step up their efforts and take note of certain practices from traditional biotech organizations when it comes to clinical research and collecting data to correctly quantify efficacy of certain products. Well-thought-out studies designed with clinical endpoints and validated questionnaires is a strategic way for the industry to take big steps towards doing what is right for patients.

Patients Are Asking For More Research

After speaking with patients who are interested in pursuing a treatment that includes the responsible use of medicinal cannabis, the one thing they all have in common is the desire for more information that they can rely on to make better decisions. Is it time for patients to push the envelope and not purchase products from companies that are not willing to perform the clinical studies? If companies suffered a loss in sales as a result, would they reconsider their stance on reinvesting capital into clinical trials with their products?

Equally as important as proper research is perpetual tele-monitoring. The value in perpetual tele-monitoring is the data. We can showcase miraculous, life-changing stories of how medical cannabis has helped people turn their lives around. However, when seeking greater buy-in from groups like the FDA, data is key. Qualitative data can go only go so far. It’s the quantitative data that will help move the medical cannabis community forward. The ability to be able to review data on an ongoing basis would enable medical cannabis companies to evaluate how products are working based on the electronic data capture, along with questions that a company may develop to ascertain individualized product feedback.

Imagine having the ability to see patients’ data based on real-time, daily, through something as convenient as a wearable device. Understanding test results and correspondence with doctors for patients would significantly improve.

CU Boulder, Charlotte’s Web Begin Sleep & Anxiety Studies

By Cannabis Industry Journal Staff

No Comments

Charlotte’s Web Holdings announced a new collaboration with the University of Colorado-Boulder and their Research and Education Addressing Cannabis and Health (REACH) Center. The University’s REACH Center will conduct a preclinical study on how hemp oil can influence sleep quality and anxiety.

The study will use Charlotte’s Web hemp products, including their full spectrum hemp formulations containing CBN, CBD and less than 0.3% THC. Monika Fleshner, PhD, Professor of Integrative Physiology and member of the Center for Neuroscience at the University of Colorado, will be the project lead and will conduct the study in her Stress Physiology Laboratory. “There is a great need for properly controlled experimental studies that are designed to test the potential neural and physiological impacts of hemp derived phytocannabinoids,” says Dr. Fleshner. “With support from CU REACH and Charlotte’s Web, our research will explore both the efficacy and mechanisms of how these substances can affect complex brain-mediated behavior, such as disturbed sleep.”

Tim Orr, senior vice president of Charlotte’s Web and president of its CW Labs division, is currently working on more than twelve scientific research studies with the company. “Charlotte’s Web is committed to advancing science on the benefits and safety of CBD and other hemp phytocannabinoids through rigorous scientific investigations such as this sleep and anxiety study,” says Orr. “We’re honored to team up with CU’s REACH Center to explore the potential impacts of full-spectrum hemp extract with CBD and CBN on anxiety and sleep quality.”

Long term, Charlotte’s Web expects this study will help build the foundation for future clinical studies to “better understand how specific ratios of cannabinoids and different delivery formats are effective at supporting improved sleep quality and instilling healthier sleep architecture in humans,” reads the press release.

Bio-Rad Aspergillus PCR Test Gets AOAC Approval

By Cannabis Industry Journal Staff

No Comments

According to a press release published earlier this month, the Bio-Rad iQ-Check Aspergilllus Real-Time PCR Detection Kit has received AOAC International approval. The test covers detection for four different Aspergillus species: A. flavus, A. fumigatus, A. niger, and A. terreus.

The detection kit covers those Aspergillus species for testing in cannabis flower and cannabis concentrates, produced with our without solvents. The PCR detection kit was validated through the AOAC Research Institute’s Performance Tested Method Program. They conducted a study that resulted in “no significant difference” between the PCR detection kit and the reference method.

The kit was evaluated on “robustness, product consistency, stability, inclusivity and exclusivity, and matrix studies,” the press release says. Bio-Rad also received approval and validation on the iQ-Check Free DNA Removal Solution, part of the workflow for testing cannabis flower.

The test kit uses gene amplification and real-time PCR detection. Following enrichment and DNA extraction, the test runs their PCR technology, then runs the CFX Manager IDE software to automatically generate and analyze results.

Bio’Rad has also recently received AOAC approval for other microbial testing methods in cannabis, including their iQ-Check Salmonella II, iQ-Check STEC VirX, and iQ-Check STEC SerO II PCR Detection Kits.

How Private-Sector-Led Information Sharing Can Transform Cybersecurity in the Cannabis Industry.

By Andy Jabbour, Ben Taylor

The cannabis industry’s advancement towards legalization continues to dominate national headlines, from the stance of incoming Attorney General Merrick Garland to deprioritize enforcement of low-level cannabis crimes, Senate Majority Leader Chuck Schumer’s continued advocacy, to the recent passing of legislation in New York, New Mexico and Virginia (the first in the South) to authorize adult-use cannabis. While these updates are likely to intrigue customers and investors alike, they are also sure to draw the attention of cyber criminals who could look at the relative youth of the industry, as well as its rapid growth, as a prime target of opportunity for nefarious acts.

In order to understand risk mitigation best practices across a wide spectrum of private sector industries, this article will first identify the current security environment in order to understand the threats, briefly highlight specific case studies and assess the risks and identify methods that individual organizations, as well as the cannabis industry as a whole, can take action to enhance security and preparedness and to develop resiliency against future attacks.

Understanding the Threats

For an industry that has operated in a largely cash-based system for much of its existence, the idea of security is not foreign. Typically, these concerns focused on physical security implementation. The topic has received plenty of coverage, including a recent article in this journal articulating Important Security Considerations When Designing Cannabis Facilities. While an audit of physical security measures is a valuable part to any all-hazards threat assessment, securing a growing online network – from email to online finances to connected devices within cannabis facilities – can pose more unfamiliar challenges. When consulted for this article, Patten Wood, a former VP of marketing for a prominent west-coast cannabis retail brand noted: “While the topic of cybersecurity is critically important to customers, businesses, and the industry at large, it isn’t top of mind for many of the cannabis companies that I’ve experienced.” Understanding what risks are present is the first step to mitigating them, so we must first discuss several common cyber threats for the cannabis industry.

Phishing: Phishing happens when cybercriminals impersonate a trusted individual or entity, typically through email. The goal in this instance is to get the target to share confidential information or download software that can allow unauthorized access into an organization’s network. Phishing is one of the most common types of cyberattacks as it is relatively easy to conduct and surprisingly effective.

Ransomware Attacks: Ransomware attacks are used to gain access to a computer network and then lock and encrypt either the entire system or certain sets of high-value files, which can compromise important business information, and impact client and vendor privacy. A ransom is then demanded for restoring access, but paying the ransom comes with its own risk as it doesn’t guarantee the files will be restored.

Cyber Extortion: Similar to ransomware attacks in their design, cyber extortion typically deals with a threat of leaking personal information and will generally demand payment in cryptocurrency in order to maintain their anonymity.

Remote Access Threats: As 2020 has forced organizations to rethink how they conduct business and shift to more remote operations than they had in the past, it can open up several new threats. According to a survey by IT social network SpiceWorks.com, six out of every ten organizations allow their employees to connect their company-issued devices to public Wi-Fi networks. Utilizing unsecured Wi-Fi networks opens the user up to man-in-the-middle attacks, allowing hackers to intercept company data. Unsecure Wi-Fi also brings the threat of malware distribution. An additional consideration with remote workers is the uptick in cyber attacks against remote access software referred to as remote desktop protocol (RDP) attacks. According to Atlas VPN, RDP attacks skyrocketed 241% in 2020 and we’ve seen numerous RDP attacks against critical infrastructure throughout the pandemic and across all industries.

Internet of Things (IoT) Leaks: With IoT devices running everything from security systems to automated growing operations, the convenience has been a huge boost for the industry. Unfortunately, many IoT devices don’t have sophisticated built-in security. Another common problem is the tendency of users to keep default passwords upon installation, which can make devices easy for cyber criminals to access. Once they are inside the system, malware can easily be installed, and the actors can move laterally throughout the network.

Personal and Medical Record Security: Many cyberattacks expose some level of personal data, whether that be customer, employee or vendor information. An extra consideration for retail operations that either treat medical patients, or medical and adult-use customers, is the additional information they must store about their clients. Medical facilities will maintain protected health information (PHI), which are much more valuable on the dark web than personally identifiable information (PII). But even adult use facilities may keep government-issued ID or other additional information above that of a typical retailer, which makes the potential value of their information much more intriguing for a cybercriminal.

Assessing the Risks

Depending on where your organization lies in the seed to sale chain, you will have different levels of risk for various types of attacks. We briefly discussed ransomware attacks earlier. Ransoms can range widely depending on the size of the organization that is attacked, but the ransom alone isn’t the only risk consideration. Businesses must also factor in the cost of downtime (an average of 18 days in 2020) caused by the ransomware when evaluating the impact to business operations, as well as reputation. While small – medium businesses are absolutely at risk, especially given their relative lack of cybersecurity resources and sophistication, a recent trend involves “Big Game Hunting” where cybercriminals are targeting larger organizations with the potential for bigger paydays. Criminals understand that big business can rarely afford major delays, and may be more able and willing to pay, and pay big, for a return to normal operations.

Below are several examples of attacks which have either directly impacted the cannabis industry, or have valuable lessons the industry can learn from.

GrowDiaries: In October 2020 researcher Bob Diachenko discovered that 3.4 million records including passwords, posts, emails and IP addresses were exposed after two open-source application Kibana apps were left exposed online. As a platform for cannabis growers around the world (who are not all growing legally), this type of exposure puts the community at great risk, and can lower user confidence in the product, as well as putting them at personal risk of harm or legal ramifications. The applications being left open is a prime example of either a lack of good cybersecurity policies, or not following through on those policies.

Aurora Cannabis: On December 25^th, 2020 Canadian company Aurora Cannabis suffered a data breach when SharePoint and OneDrive were illegally accessed. Included in the data that was compromised was credit card information, government identification, home addresses and banking details. The access point coming through Microsoft cloud software is a prime example of some of the challenges facing businesses who have an increasingly remote workforce yet still need that workforce to access critical (and usually highly sensitive) information.

THSuite: A database owned by seed to sale Point-Of-Sale (POS) software provider THSuite was discovered by researchers in December 2019. The database contained PHI/PII for 30,000 people, with over 85,000 files being exposed. The information that was left accessible included scanned government IDs, personal contact information and medical ID numbers. Clearly this gets into HIPAA territory, which can result in fines of up to $50,000 for every exposed record.

Door Dash: As cannabis delivery apps become more prevalent, it’s good to reference how similar businesses in other industries have been targeted. In May of 2019 nearly 5 million user records were accessed by an unauthorized third party, exposing PII and partial payment card information.

Taking Action

On an organizational level, employee training, password hygiene and malware protection are some of the basic and most important steps that should be taken by all organizations. But, if “knowledge is power,” the best defense for any organization against cyber threats is a well-informed organization- including leadership down to the front-line employees. Excellent tools to assist in this are Information Sharing & Analysis Centers/Organizations (ISACs/ISAOs). ISACs were established under a presidential directive in 1998 to enable critical infrastructure owners and operators to share cyber threat information and best practices. The National Council of ISACs currently has over 20 member ISACs including Real Estate, Water, Automotive and Energy. ISAOs were created by a 2015 executive order to encourage cyber threat information sharing within private industry sectors that fall outside of those listed as “critical infrastructure”. Christy Coffey, vice president of operations at the Maritime and Port Security ISAO (MPS-ISAO) says information sharing enabled by the executive order is critical. “We need to accelerate private sector information sharing, and I believe that the ISAO is the vehicle.”

According to Michael Echols, CEO of the International Association of Certified ISAO’s (IACI) at the Kennedy Space Center, security experts have long understood that threat information sharing can allow for better situational awareness and help organizations better identify common threats and ways to address them. “On the other side, hackers in a very documented way are already teaming up and sharing information on new approaches and opportunities to bring more value (to their efforts).” The ongoing crisis surrounding the Microsoft Exchange Server Vulnerability demonstrates that different cybercriminal groups will work simultaneously to abuse system flaws. As of March 5^th it was reported that at least 30,000 organizations in the U.S. – and hundreds of thousands worldwide – have backdoors installed which makes them vulnerable to future attacks, including ransomware.

Below are several links to recent products that have been shared by various ISACs/ISAOs, which are provided as an example of the type of information that is commonly shared via these organizations.

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

By Cannabis Industry Journal Staff

No Comments

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.
