An Insider’s View: How Labs Conduct Cannabis Mold Testing

As both recreational and medical cannabis legalization continues to progress across the country, each state is tasked with developing regulatory requirements to ensure that customers and patients receive clean cannabis for consumption. This requires cannabis to undergo laboratory testing that analyzes the presence of microbial impurities including yeast and mold.

Some states, such as Colorado, Nevada, Maine, Illinois and Massachusetts use total yeast and mold count testing (TYMC) and set a maximum yeast and mold count threshold that cultivators must fall below. Other states, such as California, require the detection of species-specific strains of Aspergillus mold (A. fumigatus, A. flavus, A. niger and A. terreus), which requires analyzing the DNA of a cannabis sample through polymerase chain reaction testing, also known as PCR.

Differences in state regulations can lead to different microbiological techniques implemented for testing.Before diving in further, it is important to understand the scientific approach. Laboratory testing requirements for cannabis can be separated into two categories: analytical chemistry methods and microbiological methods.

Analytical chemistry is the science of qualitatively and quantitatively determining the chemical components of a substance, and usually consists of some kind of separation followed by detection. Analytical methods are used to uncover the potency of cannabis, analyze the terpene profile and to detect the presence of pesticides, chemical residues, residuals solvents, heavy metals and mycotoxins. Analytical testing methods are performed first before proceeding to microbiological methods.

Microbiological methods dive deeper into cannabis at a cellular level to uncover microbial impurities such as yeast, mold and bacteria. The techniques utilized in microbiological methods are very different from traditional analytical chemistry methods in both the way they are performed and target of the analysis. Differences in state regulations can lead to different microbiological techniques implemented for testing. There are a variety of cell and molecular biology techniques that can be used for detecting microbial impurities, but most can be separated into two categories:

  1. Methods to determine total microbial cell numbers, which typically utilizes cell culture, which involves growing cells in favorable conditions and plating, spreading the sample evenly in a container like a petri dish. The total yeast and mold count (TYMC) test follows this method.
  2. Molecular methods intended to detect specific species of mold, such as harmful aspergillus mold strains, which typically involves testing for the presence of unique DNA sequences such as Polymerase Chain Reaction (PCR).


Among states that have legalized some form of cannabis use and put forth regulations, there appears to be a broad consensus that the laboratories should test for potency (cannabinoids concentration), pesticides (or chemical residues) and residual solvents at a minimum. On the other hand, microbial testing requirements, particularly for mold, appear to vary greatly from state to state. Oregon requires random testing for mold and mildew without any details on test type. In Colorado, Nevada, Maine, Illinois and Massachusetts, regulations explicitly state the use of TYMC for the detection of mold. In California, the recently released emergency regulations require testing for specific species of Aspergillus mold (A. fumigatus, A. flavus, A. niger and A. terreus), which are difficult to differentiate on a plate and would require a DNA-based approach. Since there are differences in costs associated and data produced by these methods, this issue will impact product costs for cultivators, which will affect cannabis prices for consumers.

 

New Drug Delivery Mechanisms For Cannabis Products

Next Frontier Biosciences announced the launch of their new product line, Verra Wellness, in the Colorado market this week. The products are designed with relatively new concepts for the cannabis market, including nasal, sublingual and topical administration.

The company claims their product is the first-ever cannabis nasal mist. Co-founded by biotech executives Marc Graboyes and Dr. Paul Johnson, Ph.D, Next Frontier Biosciences is developing this product line with three formulations, each with a different ratio of THC and CBD. According to a press release, Next Frontier Biosciences is focused on developing cannabis products with these new drug delivery methods, and even offering a microdosing option.

“We believe that leveraging science and research is the key to optimizing product development,” says Dr. Johnson, one of the co-founders. “With the introduction of our Verra Wellness line of products, we are reshaping the cannabis industry by offering trusted products that provide uniform composition, formulation and dosing in highly consistent modes of administration.”

Their topical salves in the Verra Wellness product line are “designed to permeate skin and muscle tissue deeply without penetrating the blood stream or causing psychoactive effects,” reads a press release. In addition to the nasal mist and topical salve, they also launched a sublingual spray.

According to Marc Graboyes, chief executive officer and co-founder of Next Frontier Biosciences, drug delivery mechanisms like a nasal mist are superior to smoking, vaporizing and edible administration. “Nasal administration is among the most effective delivery technologies due to the extensive vascularization and large surface area of the nasal cavity, allowing for rapid uptake and reliable results,” says Graboyes. “The cannabis nasal mist is a novel technology that other brands have not yet tapped into.”

He says this drug delivery mechanism is efficient, fast acting and a healthy alternative to smoking. “For many, nasal delivery is a desirable alternative delivery mechanism because it does not present the health risks associated with smoking,” says Graboyes. “In addition, as previously mentioned, the large surface area of the nasal cavity permits high drug absorption, and the fine-mist sprayer allows for accurate, consistent dosing and an excellent safety profile. Further, nasal delivery avoids first-pass metabolism by the liver, where a large fraction of orally delivered cannabinoids are inactivated.”

While the Verra Wellness product line is available in Colorado starting this week, the company has plans to expand into a number of other states as well. “We are executing a multi-state expansion, with plans to move into the California, Oregon, Washington and Nevada markets in the coming year,” says Graboyes.

Colorado Issues Recall, Pesticides Found In Cannabis

Last week, the Colorado Department of Revenue (DOR), the Colorado Department of Agriculture (CDA) and the Colorado Department of Public Health and Environment (CDPHE) announced a health and safety advisory for a large number of cannabis products grown and produced by Tree of Wellness Inc., doing business as Tree of Wellness. The health and safety advisory, synonymous with a product recall, was issued due to the detection of off-label pesticides in cannabis grown by Tree of Wellness.

Tests found Myclobutanil present in batches going all the way back to May, 2017, with some contaminated batches as recent as late October.

According to the press release, the CDA confirmed the presence of Myclobutanil, a near-ubiquitous fungicide used in a wide range of agricultural practices. The chemical has been a thorn in the side of the cannabis industry for being used off-label, or inappropriately, on cultivating cannabis.

Here are the batch numbers included in the recall

Myclobutanil is the active ingredient in Eagle 20, a pesticide used frequently in other agricultural fields like grapes, apples and spinach. According to UC Davis professor and Steep Hill scientist Dr. Don Land, Myclobutanil becomes significantly more dangerous when heated, or smoked. That chemical reaction produces hydrogen cyanide, an extraordinarily toxic chemical. Because of this, and the lack of research on what happens when these chemicals are burned or heated, there is a growing public concern that cannabis laced with a chemical like Myclobutanil can cause adverse health reactions.

The public health and safety advisory says they detected Myclobutanil in cannabis flower, trim, concentrates, and infused-products from Tree of Wellness. The CDPHE and DOR recommend consumers that have the affected products return them to where they were purchased for proper disposal.

Consumers in Colorado should check their labels to see if their products fall under the recall. Look for the Medical Optional Premises Cultivation License 403-00664 and/or Medical Marijuana Center License 402-00443. The recall includes batches of 23 different strains grown by Tree of Wellness.

Colorado To Begin Requiring Potency Testing For Medical Infused Products

By Aaron G. Biros

After a delay due to their proficiency testing program roll out, the Colorado Marijuana Enforcement Division (MED) will now require all medical infused products and concentrates be tested for potency and homogeneity, starting November 1st, 2017.

After November 1st, all production batches of concentrates from medical product manufacturers will need to have a potency test before being sold, transferred or processed. The same goes for medical infused products, such as edibles and topicals. The homogeneity test refers to making sure THC or other active ingredients are distributed evenly throughout the product.

According to Alex Valvassori, author of a regulatory compliance-focused blog post on Complia’s website, these new testing requirements could lead to a surge in pricing, passed on to patients. He also recommends dispensaries take a close look at labels coming in from suppliers. They need to make sure potency data is listed clearly on the label to stay compliant.

Production batches created before November 1st are not required to meet the new testing regulations, but any and all batches after that date will be required to perform those tests.

Colorado Issues Safety Advisory; More Pesticides Found In Cannabis

According to a press release issued on Friday, September 22nd, the Colorado Department of Public Health and Environment (CDPHE), along with the Colorado Department of Revenue (DOR) and the Colorado Department of Agriculture (CDA), issued a public health and safety advisory for cannabis products tainted with pesticide residue.

The advisory was issued after the detection of pesticide residues on retail cannabis plant material and products with cannabis grown by RK Enterprises LTD, doing business as Rocky Mountain Remedies. The CDA confirmed that they detected the pesticide, Avermectin, an insecticide with a relatively high acute toxicity.

When pesticides like this are not on the list approved for use in cannabis cultivation, it is considered an off-label use. According to the press release, some of the products affected include flower, trim, concentrates and infused-products.

Consumers are advised to look at the label of their products and check to see if it matches the license number 403R-00180 and harvest batch numbers r206goldenkush9.11.17 and m206larryog9.11.17. Consumers are told to either dispose of the product properly or bring it back to the retail store where they purchased it.

New Colorado Edibles Regulations Effective October 1st

By Aaron G. Biros

Back in April of 2016, the Colorado Legislature passed HB 1436 in an effort to make infused products less appealing to children. On October 1st, 2017, the new law goes into effect, which will prohibit the sale of edibles in the shape of a human, animal or fruit.

The THC universal symbol

Colorado has a history of regulating the market like this, with laws designed to limit the dosing, consistency and appeal of edibles to children. In 2015, regulators placed a 100-milligram cap on THC in infused products, separated into 10-milligram servings. In 2016, regulators began requiring the THC stamp on edibles, a symbol with a clear representation of what the product contains.

Some in the industry are welcoming of these new laws, while others think it might be overregulation. Regardless, manufacturers that have previously produced things like fruit candies or gummy bears now need to update their processes to use non-descript shapes for their products in order to stay compliant.

incredibles logoBob Eschino, founder and president of Incredibles, an infused product manufacturer in Colorado, says these rules are not very effective at preventing kids from obtaining edibles, but it could help. “I believe consumer protection comes from CRP [child-resistant packaging], proper labeling, education and safe storage,” says Eschino. “CDPHE said themselves that stamping or shaping the products is the least effective way to prevent accidental ingestion. It’s a step that will add to consumer protection in a small way, but every little bit helps for now.” There are a number of more effective measures that regulators in Colorado take to prevent edibles from getting in the hands of children, such as child-resistant packaging, prohibiting advertising of cartoon characters, requiring opaque packaging and warning messages on labels.

According to Peggy Moore, partner of Love’s Oven, an infused product manufacturer, and board president of the Cannabis Business Alliance, the major change companies need to make to stay compliant is ordering new molds. “Depending on the quantity ordered, molds can cost $10,000 or more to fabricate and produce.,” says Moore. “If a company was not using molds previously there is also training that may be required to orient production staff on technique for making molded confections.” She says there are still plenty of options for manufacturers to use like botanical shapes (a cannabis leaf, for example), circles, squares, rectangles and other shapes.

Her company, Love’s Oven, makes caramels, baked goods, crackers and other non-descript shapes already. “At this point I am not aware of any manufacturers who are not already compliant with this rule in advance,” says Moore. “The most common solution is to move to a square, circle or other shape utilizing molds. “ Moore believes it is a producer’s duty to make products that are not enticing to children. “Regardless of the industry (alcohol, cannabis, pharma) I think we should exercise great caution to not produce products that are targeting children,” says Moore. “While I would love to see manufacturers self-regulate in this regard, clearly some guardrail regulations are needed at this point.”

In addition to the rule on using non-descript shapes, HB 1436 prohibits the use of additives in retail cannabis products that are designed to make it addictive, more appealing to children or misleading consumers. The rule does, however, exclude common baking and cooking ingredients. There is also a stipulation that permits local fire departments to perform annual fire inspections at cannabis cultivation facilities.

Emerald Scientific recently announced their proficiency-testing program, The Emerald Test, has been approved by Colorado as a third party provider for proficiency testing in licensed cannabis laboratories. The Emerald Test, held twice annually, is an inter-laboratory comparison and proficiency test (ILC-PT), allowing data to be collected pertaining to the performance of laboratories on a national scale. Proficiency testing is designed to measure how accurately laboratories perform and is a critical tool for quality assurance.

Colorado requires labs to participate in a proficiency-testing program in order to be certified to conduct required testing on cannabis and cannabis products for safety and quality. According to the press release, Colorado’s Marijuana Enforcement Division, under the Department of Revenue, conducted an evaluation process to determine which applicants could meet the performance standards for regulatory compliance concerning proficiency testing. The contract was awarded to Emerald Scientific following this evaluation process.

emerald test retailAccording to Ken Groggel, director of the Proficiency Testing Program at Emerald Scientific, a number of states have recognized the need for independent proficiency testing as a required piece of regulatory compliance. “The Emerald Test Inter-Laboratory Comparison/PT is state approved in Washington & Colorado for cannabis testing laboratory licensure,” says Groggel. “States with cannabis or hemp production, as well as labs in other countries are now actively participating in the Emerald Test as a tool for quality improvement, efficiency upgrades and product safety.” He says the Colorado Marijuana Enforcement Division has contracted with Emerald Scientific to provide third party PT programs for microbial contaminants, residual solvents and pesticides.

Ken Groggel, director of the Proficiency Testing Program at Emerald Scientific

Beginning in 2014, The Emerald Test has been offered twice a year and, in 2017, over 50 labs participated from 14 states and 2 countries. “Laboratories that have enrolled more than once have seen significant improvement in their results, an indicator of improved performance for industry customers,” says Groggel.

Proficiency testing is important for ensuring quality, safety and product content accuracy. “This should be the priority whether you are a grower, manufacturer, testing laboratory, regulatory entity, medical patient or adult use consumer,” says Groggel. It also helps labs meet regulatory requirements and achieve ISO 17025 accreditation. “Independent proficiency testing helps determine if the lab is able to deliver the services marketed to its customers,” says Groggel. “Regulatory agencies can use this information when licensing, monitoring & enforcing good science for public safety.”

As new states legalize cannabis and develop consumer protection regulations, proficiency testing programs can help labs demonstrate their commitment to responsible and accurate testing. “When PT results show the cannabis testing lab is capable it is up to the government to ensure accountability for performance on behalf of all its citizens,” says Groggel. Labs can enroll starting on September 25th in the Fall 2017 Emerald Test ILC/PT.

Wana Brands Dominates Oregon Market, Expands to East Coast in 2018

Wana Brands launched their products in Oregon’s market in July 2016, about a year ago. Since then, their brand presence has grown considerably and their products are now in 240 of Oregon’s 375 dispensaries, according to a press release issued this morning.

Wana Brands is an infused products company; they make sour gummies, hard candies and caramels. The business originally launched in Colorado back in 2010 and as of 2016, they own 23% of the market share and had the most sales revenue of any edibles company in Colorado, according to BDS Analytics. The next closest competitor owns 12% of the market share.

According to Nancy Whiteman, co-founder and co-owner of Wana Brands, becoming a market leader in Oregon is a result of their product’s consistency and taste. At the end of last year they launched in Nevada and this year they will launch in Arizona and Illinois. In 2018, they expect to make a big East Coast push, expanding into Massachusetts and Maryland as well.

Election Day last year legalized recreational cannabis in a number of states, including Massachusetts, Maine and Nevada. About a week before Election Day, we interviewed Whiteman about those states coming online and her drive to expand. She said she saw a lot of potential in those markets and she was right. Nevada witnessed a massive surge in demand with the opening of recreational sales in the beginning of July and Massachusetts is expected to be another huge market potential.

In that interview, she explained a bit of their growth model: “The model we are pursuing is a licensing agreement where we partner with existing or new license holders in their state,” says Whiteman. “In many ways they are doing the heavy lifting, but we are providing an enormous lift by licensing our intellectual property to them.”

Now that her company has found enormous success in established markets like Oregon, Nevada and Colorado, they want to make a big push in those fledgling markets on the East Coast. “In both markets [Massachusetts and Maryland], we will be working with a partner who will be licensing our products,” says Whitman. “I think the East Coast is a huge opportunity.  There are major population centers in New England, New York and Florida and the markets are almost completely undeveloped at this point.” Wana Brands is also currently entering talks with partners in California, Florida and Maine.

MJ Freeway’s Source Code Stolen & Published Online

By Aaron G. Biros

Portions of MJ Freeway’s source code were reportedly stolen and posted in Reddit threads as well as on Gitlab.com, a source code hosting website. On June 15th, the account “MJFreeway Open Source” was made on Gitlab.com, and portions of the source code were posted, but have since been taken down. Source code is essentially a list of commands of a program, the basis for making improvements and modifications to a software system. Source code can sometimes contain sensitive information. To be clear, MJ Freeway does not use an open source model; their source code is the basis of their traceability software. Open source is a tool that fosters public collaboration on software development, helping identify weaknesses or areas for improvement.

When asked to comment on the matter, MJ Freeway issued the following statement:

“Last week we discovered that someone had obtained an outdated portion of MJ Freeway’s source code. This incident has absolutely no impact on our systems or MJ Freeway services, and client and patient data is not at risk. While this theft poses no risk to our clients, patients, or business operations, we take any incident involving unauthorized access very seriously and have reported it to the Colorado Bureau of Investigation.

Unfortunately, it has come to our attention that our competitors are spreading inaccurate information about the incident, including baseless claims about SSL info and the potential for client data being compromised – neither of which is true. We encourage our customers to contact us directly with any questions they may have.

We follow or exceed all relevant industry security standards and are confident that we have the most robust security measures in our industry. None of our peers come close. However, we live in a world of determined cyber-criminals and we operate in a competitive environment. Success and size makes a company a bigger target for malicious actors, as other large companies also know. We will continue to investigate and take follow-up action as we learn more about this incident.”

On Sunday, June 18th, a user by the name of ‘techdudes420’ posted in the subreddit, r/weedbiz, a thread titled “MJFreeway goes open source.” The link for that post was the Gitlab.com page where MJ Freeway’s source code was published briefly. The same user then published a second reddit post the following day with the same link to the stolen code, but this time in the r/COents, a subreddit for the Colorado cannabis community. MJ Freeway is based in Denver. That post claimed the user found the stolen source code with a quick search and that the user was banned because of that. The moderator of the thread chimed in, saying they banned the user for posting the stolen code. “We received a takedown request from the software owner stating the code had been stolen and released without permission,” says the moderator. “After investigating the matter I reached the same conclusion and removed the thread.” The moderator then updated the comment shortly after: “Edit: As for OP [original poster] ‘finding’ the code, if that were true I don’t know why he or she would have created a new Reddit account just to post the link.”

In addition to their own cybersecurity analysis, a spokeswoman for MJ Freeway says they will be performing a third party audit and analysis this week as well. When that information becomes available, we will update this article.

Update: Multiple sources have reported that portions of MJ Freeway’s source code are still available online on torrent sites like PirateBay.
