Beyond THC: Encouraging Cannabinoid and Terpene Production with LEDs

By Andrew Myers
No Comments

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

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

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

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

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

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

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

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

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

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

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

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

Indoor cultivation facilities often use high powered lights that can give off heat

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

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

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

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

By Aaron G. Biros
No Comments

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

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

Jennifer Raeder-Devens, Chief Scientific Officer at Project Yosemite

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

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

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

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

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

CIJ: What made you consider joining the cannabis industry? 

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

OLO sublingual strips have a 10-minute onset time

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

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

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

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

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

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

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

The OLO sublingual strips

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

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

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

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

3 Essential Components of Microbial Safety Testing

By Heather Ebling
No Comments

Microbial contamination on cannabis products represents one of the most significant threats to cannabis consumers, particularly immunocompromised patients who are at risk of developing harmful and potentially fatal infections.

As a result, regulatory bodies in the United States and Canada mandate testing cannabis products for certain microbes. The two most popular methods for microbial safety testing in the cannabis industry are culture-based testing and quantitative polymerase chain reaction (qPCR).

When considering patient safety, labs should choose a method that provides an accurate account of what is living on the sample and can specifically target the most harmful microbes, regardless of the matrix.

1. The Method’s Results Must Accurately Reflect the Microbial Population on the Sample

The main objective of any microbial safety test is to give the operator an indication of the microbial population present on the sample.

Figure 1: MA data collected directly from plant material before and after culture on 3M petrifilm and culture-based platforms.

Culture-based methods measure contamination by observing how many organisms grow in a given medium. However, not all microbial organisms grow at the same rate. In some cases, certain organisms will out-compete others and as a result, the population in a post-culture environment is radically different than what was on the original sample.

One study analyzed fifteen medicinal cannabis samples using two commercially available culture-based methods. To enumerate and differentiate bacteria and fungi present before and after growth on culture-based media, all samples were further subjected to next-generation sequencing (NGS) and metagenomic analyses (MA). Figure 1 illustrates MA data collected directly from plant material before and after culture on 3M petrifilm and culture-based platforms.

The results demonstrate substantial shifts in bacterial and fungal growth after culturing on the 3M petrifilm and culture-based platforms. Thus, the final composition of microbes after culturing is markedly different from the starting sample. Most concerning is the frequent identification of bacterial species in systems designed for the exclusive quantification of yeast and mold, as quantified by elevated total aerobic count (TAC) Cq values after culture in the total yeast and mold (TYM) medium. The presence of bacterial colonies on TYM growth plates or cartridges may falsely increase the rejection rate of cannabis samples for fungal contamination. These observations call into question the specificity claims of these platforms.

The Live Dead Problem

Figure 2: The enzyme is instantaneously inactivated when lysis buffer is added

One of the common objections to using qPCR for microbial safety testing is the fact that the method does not distinguish between live and dead DNA. PCR primers and probes will amplify any DNA in the sample that matches the target sequence, regardless of viability. Critics claim that this can lead to false positives because DNA from non-viable organisms can inflate results. This is often called the Live-Dead problem. However, scientists have developed multiple solutions to this problem. Most recently, Medicinal Genomics developed the Grim Reefer Free DNA Removal Kit, which eliminates free DNA contained in a sample by simply adding an enzyme and buffer and incubating for 10 minutes. The enzyme is instantaneously inactivated when lysis buffer is added, which prevents the Grim Reefer Enzyme from eliminating DNA when the viable cells are lysed (see Figure 2).

2. Method Must Be Able to Detect Specific Harmful Species 

Toxic Aspergillus spp., which is responsible for at least one confirmed death of a cannabis patient, grows poorly in culture mediums and is severely underreported by current culture-based platforms. And even when Aspergillus does grow in culture, there is a certain non-pathogenic Aspergillus species that look remarkably similar to their pathogenic cousins, making it difficult to speciate using visual identification alone.

Figure 3: The team spiked a known amount of live E. coli into three different environments

Conversely, qPCR assays, such as the PathoSEEK, are designed to target DNA sequences that are unique to pathogenic Aspergillus species, and they can be run using standard qPCR instruments such as the Agilent AriaMx. The primers are so specific that a single DNA base difference in the sequence can determine whether binding occurs. This specificity reduces the frequency of false positives in pathogen detection, a frequent problem with culture-based cannabis testing methods.

Additionally, Medicinal Genomics has developed a multiplex assay that can detect the four pathogenic species of Aspergillus (A. flavus, A. fumigatus, A. niger, and A. terreus) in a single reaction.

3. The Method Must Work on Multiple Matrices 

Figure 4: The team also placed TSB without any E. coli onto a petrifilm to serve as a control.

Marijuana infused products (MIPs) are a very diverse class of matrices that behave very differently than cannabis flowers. Gummy bears, chocolates, oils and tinctures all present different challenges to culture-based techniques as the sugars and carbohydrates can radically alter the carbon sources available for growth. To assess the impact of MIPs on colony-forming units per gram of sample (CFU/g) enumeration, The Medicinal Genomics team spiked a known amount of live E. coli into three different environments: tryptic soy broth (TSB), hemp oil and hard candy. The team then homogenized the samples, pipetted amounts from each onto 3M™ Petrifilm E. coli / Coliform Count (EC) Plates, and incubated for 96 hours. The team also placed TSB without any E. coli onto a petrifilm to serve as a control. Figures 3 and 4 show the results in 24-hour intervals.

Table 1: DNA was spiked into various MIPs

This implies the MIPs are interfering with the reporter assay on the films or that the MIPs are antiseptic in nature.

Many MIPs use citric acid as a flavoring ingredient which may interfere with 3M reporter chemistry. In contrast, the qPCR signal from the Agilent AriaMx was constant, implying there is microbial contamination present on the films, but the colony formation or reporting is inhibited.

Table 3: SenSATIVAx DNA extraction can successfully lyse the cells of the microbes
Table 2: Different numbers of DNA copies spiked into chocolate

This is not an issue with DNA-based methods, so long as the DNA extraction method has been validated on these matrices. For example, the SenSATIVAx DNA extraction method is efficient in different matrices, DNA was spiked into various MIPs as shown in Table 1, and at different numbers of DNA copies into chocolate (Table 2). The SenSATIVAx DNA extraction kit successfully captures the varying levels of DNA, and the PathoSEEK detection assay can successfully detect that range of DNA. Table 3 demonstrates that SenSATIVAx DNA extraction can successfully lyse the cells of the microbes that may be present on cannabis for a variety of organisms spiked onto cannabis flower samples.

Cannabis Growers and Distributors: Your Cyber Risk is Growing Like Weeds

By Emily Selck
No Comments

Cannabis growers and distributors are “green” when it comes to cyber security. Unaware of the real risks, cannabis businesses consistently fall short of instituting some of the most basic cybersecurity protections, leaving them increasingly vulnerable to a cyber-attack.

Cannabis businesses are especially attractive to hackers because of the vast amount of personally identifiable and protected health information they’re required to collect as well as the crop trade secrets they store. With businesses growing by leaps and bounds, and more and more Americans and Canadians purchasing cannabis, cybercriminals are likely to increase their attacks on the North American market in the coming year. Arm your cannabis business with the following best practices for growers and distributors.

Distributor Risk = A Customer’s PII

Cyber risk is the greatest for cannabis distributors, required to collect personal identifiable information (PII), including driver’s licenses, credit cards, medical history and insurance information from patients. State regulatory oversight further compounds the distributor’s risk of cyber-attack. If you’re a cannabis distributor, you’ll want to make sure to:

  • Know where you retain buyer information, and understand how it can potentially be breached. Are you scanning driver’s licenses into a database, or retaining paper files? Are you keeping them in a secure area off site, or on a protected network? Make sure a member of your management team is maintaining compliance with HIPAA and state statutes and requirements for cannabis distribution.
  • Institute strong employee oversight rules. Every employee does not have to have access to every sale, or your entire database of proprietary customer information. Delegate jobs behind the sales desk. Give each employee the access they need to do their job – and that’s it.
  • Distributors have to protect grower’s R&D information too. Most cannabis distributors have access to their grower’s proprietary R&D information so they can help customers understand which products are best for different medical symptoms/needs. Make sure your employees don’t reveal too much to put your suppliers in potential risk of cyberattack.

Grower Risk = Crop Trade Secrets

For cannabis growers, the risk is specific to crop trade secrets, research and development (R&D). If you’re a cannabis grower, you’ll want to:

  • Secure your R&D process. If you’ve created a cannabis formula that reduces anxiety or pain or boosts energy, these “recipes” are your competitive advantage – your intellectual property. Consider the way you store information behind the R&D of your cannabis crops. Do you store it on electronic file, or a computer desktop? What type of credentials do people need to access it? Other industries will use a third party cloud service to store their R&D information, but with cannabis businesses that’s typically not the case. Instead, many growers maintain their own servers because they feel this risk is so great, and because their business is growing so fast, there are not yet on the cloud.
  • Limit the number of people with access to your “secret sauce.” When workers are harvesting crop, or you’re renting land from farmers and planting on it, make sure to keep proprietary information in the hands of just the few who need it – and no one else. This is especially important when sharing details with third party vendors.

Cyber coverage is now ripe for picking

Although cannabis businesses are hard to insure – for just about every type of risk – cyber insurance options for cannabis companies have recently expanded, and come down in price. If you’ve looked for cyber coverage in the past and were previously unable to secure it, now is the time to revisit the market.

Know that cyber policy underwriters will do additional due diligence, going beyond the typical policy application, and ask about the types of proprietary information you collect from customers, as well as how you store and access it at a later date. Have this knowledge at your fingertips, and be ready to talk to underwriters about it when you’re bidding for a new policy – and at renewal time.

Clinical Trials Commence for CBD Pet Products

By Aaron G. Biros

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.

HACCP

Implementing a HACCP Plan to Address Audit Concerns in the Infused Market

By Daniel Erickson

HACCP

The increasing appeal and public acceptance of medical and recreational cannabis has increased the focus on the possible food safety hazards of cannabis-infused products. Foodborne illnesses from edible consumption have become more commonplace, causing auditors to focus on the various stages of the supply chain to ensure that companies are identifying and mitigating risks throughout their operations. Hazard Analysis and Critical Control Points (HACCP) plans developed and monitored within a cannabis ERP software solution play an essential role in reducing common hazards in a market currently lacking federal regulation.

What are cannabis-infused products?

Cannabis infusions come in a variety of forms including edibles (food and beverages), tinctures (drops applied in the mouth), sprays (applied under the tongue), powders (dissolved into liquids) and inhalers. Manufacturing of these products resembles farm-to-fork manufacturing processes common in the food and beverage industry, in which best practices for compliance with food safety regulations have been established. Anticipated regulations in the seed-to-sale marketplace and consumer expectations are driving cannabis infused product manufacturers to adopt safety initiatives to address audit concerns.

What are auditors targeting in the cannabis space?

The cannabis auditing landscape encompasses several areas of focus to ensure companies have standard operating procedures (SOP’s) in place. These areas include:

  • Regulatory compliance – meeting state and local jurisdictional requirements
  • Storage and product release – identifying, storing and securing products properly
  • Seed-to-sale traceability –  lot numbers and plant identifiers
  • Product development – including risk analysis and release
  • Accurate labeling –  allergen statements and potency
  • Product sampling – pathogenic indicator and heavy metal testing
  • Water and air quality –  accounting for residual solvents, yeasts and mold
  • Pest control – pesticides and contamination

In addition, auditors commonly access the reliability of suppliers, quality of ingredients, sanitary handling of materials, cleanliness of facilities, product testing and cross-contamination concerns in the food and beverage industry, making these also important in cannabis manufacturers’ safety plans.

How a HACCP plan can help

HACCPWhether you are cultivating, harvesting, extracting or infusing cannabis into edible products, it is important to engage in proactive measures in hazard management, which include a HACCP plan developed by a company’s safety team. A HACCP plan provides effective procedures that protect consumers from hazards inherent in the production and distribution of cannabis-infused products – including biological, chemical and physical dangers. With the lack of federal regulation in the marketplace, it is recommended that companies adopt these best practices to reduce the severity and likelihood of compromised food safety.

Automating processes and documenting critical control points within an ERP solution prevents hazards before food safety is compromised. Parameters determined within the ERP system are utilized for identification of potential hazards before further contamination can occur. Applying best practices historically used by food and beverage manufacturers provides an enhanced level of food safety protocols to ensure quality, consistency and safety of consumables.

Hazards of cannabis products by life-cycle and production stage

Since the identification of hazards is the first step in HACCP plan development, it is important to identify potential issues at each stage. For cannabis-infused products, these include cultivation, harvesting, extraction and edibles production. Auditors expect detailed documentation of HACCP steps taken to mitigate hazards through the entire seed-to-sale process, taking into account transactions of cannabis co-products and finished goods at any stage.

Cultivation– In this stage, pesticides, pest contamination and heavy metals are of concern and should be adequately addressed. Listeria, E. coli, Salmonella and other bacteria can also be introduced during the grow cycle requiring that pathogenic indicator testing be conducted to ensure a bacteria-free environment.

Harvesting– Yeast and mold (aflatoxins) are possible during the drying and curing processes. Due to the fact that a minimal amount of moisture is optimal for prevention, testing for water activity is essential during harvesting.

Extraction – Residual solvents such as butane and ethanol are hazards to be addressed during extraction, as they are byproducts of the process and can be harmful. Each state has different allowable limits and effective testing is a necessity to prevent consumer exposure to dangerous chemical residues.

Edibles– Hazards in cannabis-infused manufacturing are similar to other food and beverage products and should be treated as such. A risk assessment should be completed for every ingredient (i.e. flour, eggs, etc.), with inherent hazards or allergens identified and a plan for addressing approved supplier lists, obtaining quality ingredients, sanitary handling of materials and cross-contamination.

GMPFollowing and documenting the HACCP plan through all of the stages is essential, including a sampling testing plan that represents the beginning, middle and end of each cannabis infused product. As the last and most important step before products are introduced to the market, finished goods testing is conducted to ensure goods are safe for consumption. All information is recorded efficiently within a streamlined ERP solution that provides real-time data to stakeholders across the organization.

Besides hazards that are specific to each stage in the manufacturing of cannabis-infused products, there are recurring common procedures throughout the seed-to-sale process that can be addressed using current Good Manufacturing Practices (cGMP’s).  cGMPs provide preventative measures for clean work environments, training, establishing SOPs, detecting product deviations and maintaining reliable testing. Ensuring that employees are knowledgeable of potential hazards throughout the stages is essential.Lacking, inadequate or undocumented training in these areas are red flags for auditors who subscribe to the philosophy of “if it isn’t documented, it didn’t happen.” Training, re-training (if necessary) and documented information contained within cannabis ERP ensures that companies are audit-ready. 

Labeling

The importance of proper labeling in the cannabis space cannot be understated as it is a key issue related to product inconsistency in the marketplace. Similar to the food and beverage industry, accurate package labeling, including ingredient and allergen statements, should reflect the product’s contents. Adequate labeling to identify cannabis products and detailed dosing information is essential as unintentional ingestion is a reportable foodborne illness. Integrating an ERP solution with quality control checks and following best practices ensures product labeling remains compliant and transparent in the marketplace.

Due to the inherent hazards of cannabis-infused products, it’s necessary for savvy cannabis companies to employ the proper tools to keep their products and consumers safe. Utilizing an ERP solution that effectively manages HACCP plans meets auditing requirements and helps to keep cannabis operations one step ahead of the competition.

Pesticide Testing: Methods, Strategies & Sampling

Editor’s Note: The following is based on research and studies performed in their Santa Cruz Lab, with contributions from Mikhail Gadomski, Lab Manager, Ryan Maus, Technical Services Analyst, Dr. Laurie Post, Director of Food Safety & Compliance, Andy Sechler, Lab Director, Toby Astill, Senior Business Development Leader at Perkin Elmer and Charles Deibel, President of Deibel Cannabis Labs.


Pesticides represent the leading cause of batch failures in the cannabis industry. They are also the hardest tests to run in the laboratory, even one equipped with state-of-the-art equipment. The best instruments on the market are HPLC and GC dual mass spectrometer detectors, called “HPLC-qqq”, “GC-qqq,” or just triple quads.

As non-lab people, we envision a laboratory that can take a cannabis sample, inject it into a triple quad and have the machine quickly and effortlessly print out a report of pesticide values. Unfortunately, this is far from reality. The process is much more hands on and complex.In the current chemistry lab, trained analysts have to first program the triple quads to look for the pesticides of concern; in cannabis pesticide testing, this is done by programming the first of two mass spectrometers to identify a single (precursor) mass that is characteristic of the pesticide in question. For BCC requirements in California, this has to be done for all 66 pesticides, one at a time.

Next, these precursor ions are degraded into secondary chemicals called the “product” ions, also called transition ions. The second of the two mass spectrometers is used to analyze these transition ions. This process is graphed and the resulting spectrum is analyzed by trained chemists in the lab, pesticide by pesticide, for all the samples processed that day. If the lab analyzes 10 samples, that translates to 660 spectra to analyze (66 pesticides x 10 samples). When looking at the spectra for each pesticide, the analysts must compare the ratios of the precursor ions to the product ions.

Confirmation Testing

If these spectra indicate a given pesticide may be present, the chemists must then compare the ratios between the precursor and the products. If these ratios are not what is expected, then the analyst must perform confirmation testing to prove the precursor mass either is or is not the pesticide of concern. If the ratios are not what is expected, it means the molecule is similar to the pesticide in question, but may not be that pesticide. This confirmatory testing is key to producing accurate results and not failing batches when dealing with closely related chemicals. This process of analyzing spectra is done in all labs that are performing pesticide testing. In this fledgling industry, there are few published cannabis pesticide methods. 

The need for this type of confirmation testing doesn’t happen all of the time, but when it does, it will take longer than our targeted three-day turn-around time. In the picture above, one precursor mass is ionized into several product masses; but only two are large enough to be used for comparison. In this hypothetical situation, two product masses are produced for every one precursor, the expected ion abundance ratio should be less than 30%. When performing any confirmatory testing, if the ion abundance ratio is >30%, it means the original precursor molecule was not the pesticide of concern. For example, if the ion abundance ratio was 50%, then the original molecule broke down into too many parts; it was not the pesticide we were looking for. This ion abundance ratio threshold was established by FANCO, the international organization that sets guidelines for all pesticide testing.

Testing Strategies

Methodology: In this fledgling industry, there are few published cannabis pesticide methods. The identification of the precursor mass and product ions are not always published, leaving labs to research which ions should be used. This adds to the potential for differences between lab results. Once selected, labs should validate their research, through a series of experiments to ensure the correct precursor and transition (product) ions are being used in the method.

Sample Preparation: Beyond the time-consuming work that is required to develop sound pesticide methods, the extraction step is absolutely critical for credible results. If the pesticides aren’t fully extracted from the cannabis product, then the results will be lower than expected. Sample preparations are often not standardized between labs, so unless a given extraction technique is validated for accuracy, there is the possibility for differences between labs.

Getting a Representative Sample

The current California recommended amount of sample is one gram of product per batch. Batch sizes can vary greatly and it is entirely likely that two different one gram samples can have two different results for pesticides. Has the entire plant been evenly coated with exactly the same amount of pesticide onto every square inch of its leaves? No, probably not. That is why it is imperative to take a “random” sample, by taking several smaller samples from different areas of the entire batch.

Sampling Plans: We can learn a lot from the manufacturing and sampling best practices developed by the food industry through the years. If a food manufacturer is concerned with the possibility of having a bacteria pathogen, like Salmonella, in their finished product, they test the samples coming off their production lines at a statistically relevant level. This practice (theory) is called the sampling plan and it can easily be adapted to the cannabis industry. The basic premise is that the more you test, the higher your likelihood of catching a contaminate. Envision a rectangular swimming pool, but instead of water, it’s filled with jello. In this gelatinous small pool, 100 pennies are suspended at varying levels. The pennies represent the contaminates.

Is the pool homogenized? Is jello evenly represented in the entire pool? Yes. 

Is your concentrate evenly distributed in the extraction vessel? Yes. The question is, where are the pennies in that extraction vessel? The heavy metals, the microbial impurities and the pesticides should be evenly distributed in the extraction vessel but they may not be evenly represented in each sample that is collected. Unfortunately, this is the bane of the manufacturing industry and it’s the unfortunate reality in the food industry. If you take one random cup of jello, will you find the penny? Probably not. But it you take numerous 1 cup samples from random areas within the batch, you increase your chances of finding the contaminate. This is the best approach for sampling any cannabis product.

The best way to approve a batch of cannabis product is to take several random samples and composite them. But you may need to run several samples from this composite to truly understand what is in the batch. In the swimming pool example, if you take one teaspoon scoop, will you find one of the pennies? The best way to find one of the pennies is to take numerous random samples, composite them and increase the number of tests you perform at the lab. This should be done on any new vendor/cultivator you work with, in order to help establish the safety of the product.

Protecting Intellectual Property In Canada: A Practical Guide, Part 1

Cannabis producers are making large investments in new technologies to improve their plant varieties, production know-how and product formulations. At the same time, producers are working hard to create and promote more compelling, top-of-mind brand identities for their improved products. The series concludes with a 9-point outline of specific steps cannabis producers need to consider taking to protect their key intellectual property assets. 

The value of these investments cannot be realized if competitors are allowed to copy and exploit the producer’s successes. Canada’s intellectual property laws can and should be used to protect cannabis producers from such predation. Invoking Canada’s laws to this end is not difficult and does not have to be expensive. It does, however, require specific, deliberate and early action.

This series of articles outlines the principal means of protecting intellectual property rights in the core technologies and marketing programs of cannabis companies. The series also highlights what any cannabis company must do to ensure that its own activities do not run afoul of another’s rights. No company wants to begin a new venture only to face a lawsuit for intellectual property infringement.

The series concludes with a 9-point outline of specific steps cannabis producers need to consider taking to protect their key intellectual property assets.

Trade Secrets: Protection For Confidential Know How

A trade secret is specific, commercially valuable information and know-how that is kept confidential within the company and cannot generally be reversed-engineered by outsiders. A trade secret provides protection over any type of information or know-how and is not subject to any expiry date. Trade secret protection is lost only when the information or know-how becomes available to the public.

As a best practice, defining the trade secret in a confidential document can be useful as a way of restricting access to the secretCannabis producers generate all kinds of valuable know-how that cannot be appreciated simply from an inspection of the vended product. Examples would include methods of crossbreeding, cultivation, harvesting, extraction and processing. Customer lists and other internal business structures and information may also qualify as trade secrets.

There are no statutory pre-conditions that must be met to obtain a trade secret. A trade secret is acquired simply upon the generation of valuable information or know-how that is kept confidential. As a best practice, defining the trade secret in a confidential document can be useful as a way of restricting access to the secret, and as evidence in proceedings as to the scope of the trade secret (an issue that is frequently in dispute in such cases).

For the trade secret to be maintained, the producer will need to take steps to ensure that access to the know-how and associated documents is restricted only to those who need to know the secret for purposes of carrying out their functions at the company. All personnel with access to the trade secret will need to be bound to confidence by employment agreement and/or by separate contract. When employees leave, they ought to be reminded of their obligations of confidentiality and must be prohibited from removing any documentation regarding the trade secret from the company. All outside companies who need access to the secret must sign non-disclosure agreements. It is typical for owners of trade secrets to be vigilant in their market surveillance and to engage private investigators when they suspect a trade secret has been stolen.

A trade secret’s very confidentiality provides its principal value. A competitor cannot copy what it has no ability to discern. However, when someone with access to the secret ‘goes rogue’, such as by using the know-how for his or her own account or for that of a new employer, the owner of the trade secret must act quickly and bring the matter before the Court. The Court has a broad discretion to stop the rogue and any persons or companies who learn the secret from the rogue from further dissemination or exploitation of the trade secret. The Court also has a broad discretion to craft an appropriate remedy to compensate the trade-secret owner for the wrong. If the action is brought before the trade secret is broadly disseminated, the trade secret may be reinstated and enforceable in the future. If the owner of the secret acts too slowly and the dissemination of the trade secret becomes too broad, the trade secret may be lost forever.

Adopting the use of trade secrets to protect know-how in the cannabis business does suffer from the fragility of the right itself. One disclosure, however inadvertent, can destroy the protection. In addition, a trade secret will not protect a company from a competitor who independently derives the know-how. Further, theft of the trade secret can be difficult to spot because, by its nature, the trade secret is exploited within the walls of the competitor company and is not evident in the marketed product. The owner of the secret will need to watch its competitors for telltale shifts in business direction and product offerings, particularly when those competitors hire the ex-employees of the owner of the trade secret. It is typical for owners of trade secrets to be vigilant in their market surveillance and to engage private investigators when they suspect a trade secret has been stolen.

A2LA Partners With ATACH

By Aaron G. Biros

Last week, the American Association for Laboratory Accreditation (A2LA) and the American Trade Association for Cannabis and Hemp (ATACH) announced a new partnership agreement. This partnership is the first of its kind where a laboratory accreditation body and a cannabis trade organization work together under an MOU.

According to the press release, the two organizations hope to promote “foundational standards for quality control testing and regulatory guidelines that promote product safety.” Both organizations will advocate for the adoption of industry standards they deem appropriate for recreational and medical cannabis as well as hemp testing in the United States.

Michael Bronstein, executive director of ATACH, says there is an urgent need for open-source consensus standards and standard test methods for cannabis testing. “In an industry that lacks standard test methods and where testing is such a crucial part of the regulatory landscape, the need for open-source consensus standards is especially significant,” says Bronstein. “The development and adoption of standard test methods for cannabis testing is essential in ensuring consistency between laboratories, encouraging uniformity in state testing regulation, and providing a safe and consistent product to consumers.”

The press release also states that A2LA and ATACH seek to “develop regulation and adopt industry standards with goals of advancing and professionalizing the industry.”

German Court Stops Pending Cannabis Cultivation Bid On Technical Fault

By Marguerite Arnold

In a move that seems to shed more doubt than certainty on domestic cannabis cultivation and the date that it will start auf Deutschland, the Higher Regional Court (or OLG) in Dusseldorf formally stopped the pending bid procedure for the first crop on March 28th. BfArM, the federal agency in charge of regulating all narcotic drugs, initiated that procurement bid. The tender bid was launched after the German Parliament and federal legislators changed the law last year to mandate that cannabis be available via prescription, and further that public health insurers were required to cover it.

That bid announcement was supposed to come as early as last September. Criticisms about the process and requirements began immediately thereafter. For starters, the bid’s requirements excluded all German-only respondents to the bid and left both Canadian and Israeli firms in the front positions to obtain these valuable licenses. However, there were other gripes, including the fact that the amount of cannabis requested (about 6.6 tonnes) was far too low to even begin to meet real demand. Namely, there are easily 1 million German patients who could qualify for the drug.

In the space of the last year, in fact, the number of “official” German cannabinoid patients has shot up from 1,000 to about 15,000. That said, the top three covering insurers also report a mere 64% approval rate. This means that there are more doctors writing prescriptions than insurers are covering.

That, at least for patients and their advocates is a bit of good news despite the blow that any delay in domestic production has created. Doctor resistance to prescribing cannabinoids even when there are no other alternatives has been used as an excuse in many media reports for the speed of market development. That clearly is not true. The attitude on the ground in Deutschland is rapidly changing.

That bid announcement was supposed to come as early as last September. At that point, however,the agency was then forced to extend the response date, which it did, but apparently not for long enough.

Throughout the fall, it was impossible to understand, from any direction, what was going on. Four lawsuits against the bid were launched around September, each with differing complaints that ranged from criticizing the agency for the lack of extension and response time to monopolistic business practices.

The OLG dismissed all but the criticism about the extension.what this decision has done most clearly is slowed down the production of domestically grown medical cannabinoids

The one clear thing to come out of Düsseldorf? BfArM has been banned from awarding its contract to anyone to produce medical cannabis in Germany starting in 2019. The first letters to bid finalists announcing the bid had been canceledbegan arriving the day after the court’s decision.

Reading Between the Lines

There have been rumors since last fall that the bid would end up in such waters. However,all the major producers widely suspected to have applied for the bid also began announcing themselves as finalists in press releases. For this reason, the official line from everyone that the bid was still, in fact, on track.

Nobody could understand why anyone would want or even be able to halt the production of direly needed, locally sourced, high-gradecannabis. That includes BfArM, which made an impassioned response, via their attorney to the OLG in Dusseldorf. Attorney Heike Dahs warned the court that any interruption of the bid was “very bad for the care of patients.”  He was similarly pessimistic about the ability to begin production domestically by the previously set 2019 deadline.

In fact, what this decision has done most clearly is slowed down the production of domestically grown medical cannabinoids (although potentially not by much) while giving officials at BfArM a rather nasty black eye that might yet lead to further legal action.

It also means that there will be another bid process. In the meantime, the ex-im market is, if anything, taking off.

This is a Shock And Opportunity – but not a Surprise

No matter the opinionated emails and IM’ing going on in several languages all over the world right now about the implications legally in the future, the major producers are all taking this in stride. And appear to be well positioned to respond.

According to Dr. Pierre Debs, the managing director of Spektrum Cannabis (the global medical brand of Canopy and based just south of Frankfurt), who responded to CannabisIndustryJournal a day after the court decision, the company is not affected by this development. “Spektrum has a steady and constant supply and we do not anticipate any problems supplying patients through their pharmacies,” he says. Debs received the first German medical import license to bring Canadian cannabis into the country a mere two years ago and has continued to carve a leading path in the discussion across Europe. “In addition to our supply from Canopy Growth Corp, our partnership supply agreement with Alcaliber in Spain will see Spektrum importing sun-grown medical cannabis products starting towards the end of the summer,” says Debs.

But it is not just the big guys in the mix anymore. And there are many who see opportunityto a situation, which is frustrating.“As the second-largest country by population in Europe and a leader within the EU, the German market represents a new frontier for the cannabis industry in general in the region,” says Zlatko Keskovski, chief executive officer of NYSK Holdings, a Macedonian firm now in its second harvest of GMP-certified cannabis and holding EU export rights.

For such firms, even though NYSK is a surprise entrant to the conversation this year and outside the EU, the current situation represents an unbelievable chance to enter a market literally starving for qualifiedproduct. The firm is currently looking for German distributors who cannot access medical grade cannabinoids via other routes including attending the ICBC in Berlin in April. “This year’s ICBC looks to be a seminal moment for NYSK,” says Keskovski. “We have taken the appropriate steps to ensure our high-quality standards have led to products that our customers, and eventually patients, can rely on. We look forward to the chance to showcase our achievements that we’ve worked so hard for. The ICBC will also present us with the opportunity to meet with potential distributors and future partners.”

German Patients are Going to be on the Front Lines of This Discussion

The difficulties that German patients have already faced in obtaining a drug that is now legal in their own country for medical use (and even for recreational purposes across an open border in Holland) are legion. While to a certain extent, German patients are in the same boat as patients elsewhere and their problems, in fact, there are still huge access issues that remain. For starters, the drug is much more expensive here, so those without health insurance approval face bills of about $3,000 per month. Why the eye-watering price? All medical grade cannabis is still imported, although increasingly this is now just via other EU countries, not just from Canada.

“One of the reasons we organized the national German Patient Roundtable is to give patients a voice in all of this supply and demand discussion and to help BfArM and others formulate workable solutions for all,” responded Philip Cenedella IV when reached for a response by CIJ. Cenedella, an American expat and the organizer of the Roundtable, a nationally focussed, umbrella group that is kicking off its campaign this year, spoke for many who are far from court and boardrooms where the decisions are being made.

“While there are very talented firms who will now take up this discussion with the government and reissue a response for the tender, what we continue to see on the ground is that patients simply do not have the access granted them in the law which was passed over a year ago,” Cenedella says, with more than a note of frustration. “We again are calling on all government officials, industry executives and patient advocates to band together to immediately establish workable protocols that directly help the patients.”

Indeed, despite the frustration and delay, if not new costs and opportunities that this decision creates, one thing is very clear on the ground here. The current status quo is unacceptable. That alone should also put pressure on the powers that be to remedy the situation as quickly as possible. And via several routes, including widening import quotas or even issuing new licenses as a new solution to domestic cultivation is implemented.

“Patients are not being served and do not have access to a medicine that has been proven to improve lives,” says Cenedella. “Our simple request is for BfArM to finally invite patients into their discussions, to work with patients to formulate workable cultivation and distribution solutions, and we humbly request that this happen now before they go down another dead-end road, ending in another court defeat, and resulting in even more delays to the patients that are still lacking the care afforded them by the German Federal Court’s decision of 2017.”
