Ask the Experts: Microbiological Contamination in Cannabis & What You Should Look for

By Cannabis Industry Journal Staff

Testing cannabis and cannabis derived products for microbiological contamination should be a straightforward conversation for testing labs and producers. However, a patchwork of regulations and a wide variety of perspectives on what we should, or should not, be looking for has left much of the cannabis industry searching for reliable answers.

Organizations like the AOAC are taking the first crack at creating standardization in the field but there is still a long way to go. In this conversation, we would like to discuss the general requirements that almost all states share and where we see the industry headed as jurisdictions start to conform to the recommendations of national organizations like AOAC.

We sat down with Anna Klavins and Jessa Youngblood, two cannabis testing experts at Hardy Diagnostics, to get their thoughts on microbiology testing in the current state of the cannabis industry.

Q: What are the biggest challenges facing cannabis testing labs when it comes to microbiology?

The CompactDry Yeast and Mold Rapid plate provides fast results.

Anna Klavins & Jessa Youngblood: For microbiology testing, it comes down to a lack of standardization and approved methods for cannabis. In the US, cannabis regulation is written on a state-by-state level. As a result, the rules that govern every aspect of bringing these materials to market is as unique and varied as the jurisdiction writing them. When we are speaking specifically about microbiology, the question always comes back to yeast and mold testing. For some, the challenge will often be centered on the four main Aspergillus species of concern – A. terreus, A. niger, A. fumigatus, and A. flavus. For others, it will be the challenges of total count testing with yeast, mold, and bacteria. These issues become even more troublesome by the lack of recognized standard methodology. Typically, we expect the FDA, USP, or some other agency to provide the guidelines for industry – the rules that define what is safe for consumption. Without federal guidance, however, we are often in a situation where labs are required to figure out how to perform these tests on their own. This becomes a very real hurdle for many programs.

Q: Why is it important to use two different technologies to achieve confirmation?

Dichloran Rose Bengal Chloramphenicol (DRBC) Agar is recommended for the enumeration of yeasts and molds.

Klavins & Youngblood: The push for this approach was borne out of the discussions happening within the industry. Scientists and specialists from across disciplines started getting together and creating groups to start to hash out problems which had arisen due to a lack of standardization. In regards to cannabis testing, implementing a single method for obtaining microbiology results could be unreliable. When clients compared results across labs, the inconsistencies became even more problematic and began to erode trust in the industry. As groups discussed the best way to prove the efficacy of their testing protocol, it quickly became apparent that relying on a single testing method was going to be inadequate. When labs use two different technologies for microbiology testing, they are able to eliminate the likelihood of false positives or false negatives, whichever the case may be. In essence, the cannabis testing laboratories would be best off looking into algorithms of detecting organisms of interest. This is the type of laboratory testing modeled in other industries and these models are starting make their way into the cannabis testing space. This approach is common in many food and pharma applications and makes sense for the fledgling cannabis market as well.

PerkinElmer Awarded Five Emerald Test Badges

By Aaron G. Biros

1 Comment

According to a press release published today, Emerald Scientific awarded PerkinElmer five badges for The Emerald Test, a bi-annual Inter-Laboratory Comparison and Proficiency Test (ILC/PT) program. Awarding the badges for Perkin Elmer’s instruments and testing methods affirms their ability to accurately detect pesticides, heavy metals, residual solvents, terpenes and potency in cannabis.

According to Greg Sears, vice president and general manager of Food, Chromatography & Mass Spectrometry, Discovery & Analytical Solutions at PerkinElmer, they are the only instrument manufacturer to receive all five accolades. “To date, PerkinElmer is the only solutions provider to successfully complete these five Emerald Scientific proficiency tests,” says Sears. “The badges underscore our instruments’ ability to help cannabis labs meet the highest standards available in the industry and effectively address their biggest pain point: Navigating diverse regulations without compromising turnaround time.”

The instruments used were PerkinElmer’s QSight 220 and 420 Triple Quad systems, which are originally designed for accurate and fast detection/identification of “pesticides, mycotoxins and emerging contaminants in complex food, cannabis and environmental samples,” reads the press release. They also used their ICP-MS, GC/MS and HPLC systems for the badges.

PerkinElmer says they developed a single LC/MS/MS method using their QSight Triple Quad systems, which helps labs test for pesticides and mycotoxins under strict regulations in states like California and Oregon. They performed studies that also confirm their instruments can help meet Canada’s testing requirements, which set action limits nearly 10 times lower than California, according to the press release.

Gas Chromatography/Infrared Spectroscopy: A Tool For the Analysis of Organic Compounds in Cannabis

By John F. Schneider

2 Comments

Editor’s Note: The author will be teaching a 1/2 day short course on this topic at PITTCON in Philadelphia in March 2019.

The combination of gas chromatography and infrared spectroscopy (GC/IR) is a powerful tool for the characterization of compounds in complex mixtures. ^(1-5) Gas chromatography with mass spectroscopy detection (GC/MS) is a similar technique, but GC/MS is a destructive technique that tears apart the sample molecules during the ionization process and then these fragments are used to characterize the molecule. In GC/IR the molecules are not destroyed but the IR light produced by molecular vibrations are used to characterize the molecule. IR spectrum yields information about the whole molecule which allows the characterization of specific isomers and functional groups. GC/IR is complementary to GC/MS and the combination results in a powerful tool for the analytical chemist.

A good example of the utility of GC/IR vs GC/MS is the characterization of stereo isomers. Stereo isomers are mirror images such as a left hand and a right hand. In nature, stereo isomers are very important as one isomers will be more active then its mirror image. Stereo isomers are critical to medicinal application of cannabis and also a factor in the flavor components of cannabis.

GC/MS is good at identifying basic structure, where GC/IR can identify subtle differences in structure. GC/MS could identify a hand, GC/IR could tell you if it is a left hand or right hand. GC/MS can identify a general class of compounds, GC/IR can identify the specific isomer present.

Why GC/IR?

Gas chromatography interfaced with infrared detection (GC/IR), combines the separation ability of GC and the structural information from IR spectroscopy. GC/IR gives the analyst the ability to obtain information complementary to GC/MS. GC/IR gives the analyst the power to perform functional group detection and differentiate between similar molecular isomers that is difficult with GC/MS. Isomer specificity can be very important in flavor and medical applications.

Gas chromatography with mass spectrometry detection (GC/MS) is the state-of-the-art method for the identification of unknown compounds. GC/MS, however, is not infallible and many compounds are difficult to identify with 100 % certainty. The problem with GC/MS is that it is a destructive method that tears apart a molecule. In infrared spectrometry (IR), molecular identification is based upon the IR absorptions of the whole molecule. This technique allows differentiation among isomers and yields information about functional groups and the position of such groups in a molecule. GC/IR complements the information obtained by GC/MS.

Interfaces

Initial attempts to couple GC with IR were made using high capacity GC columns and stopped flow techniques. As GC columns and IR technology advanced, the GC/IR method became more applicable. The advent of fused silica capillary GC columns and the availability of Fourier transform infrared spectrometry made GC/IR available commercially in several forms. GC/IR using a flow cell to capture the IR spectrum in real time is known as the “Light Pipe”. This is the most common form of GC/IR and the easiest to use. GC/IR can also be done by capturing or “trapping” the analytes of interest eluting from a GC and then measuring the IR spectrum. This can be done by cryogenically trapping the analyte in the solid phase. A third possibility is to trap the analyte in a matrix of inert material causing “Matrix Isolation” of the analyte followed by measuring the IR spectrum.

Infrared Spectroscopy

The physical state of the sample has a large effect upon the IR spectrum produced. Molecular interactions (especially hydrogen bonding) broadens absorption peaks. Solid and liquid samples produce IR spectra with broadened peaks that loses much of the potential information obtained in the spectra. Surrounding the sample molecule with gas molecules or in an inert matrix greatly sharpens the peaks in the spectrum, revealing more of the information and producing a “cleaner” spectrum. These spectra lend themselves better to computer searches of spectral libraries similar to the computer searching done in mass spectroscopy. IR spectral computer searching requires the standard spectra in the library be of the same physical state as the sample. So, a spectrum taken in a gaseous state should be searched against a library of spectra of standards in the gaseous state.

IR of various phases:

Liquid Phase – Molecular interactions broaden absorption peaks.
Solid Phase – Molecular interactions broaden absorption peaks.
Gas Phase – Lack of molecular interactions sharpen absorption peaks.
Matrix Isolation – Lack of molecular interactions sharpen absorption peaks.

IR Chromatograms

GC/IR yields chromatograms of infrared absorbance over time. These can be total infrared absorbance which is similar to the total ion chromatogram (TIC) in GC/MS or the infrared absorbance over a narrow band or bands analogous to selected ion chromatogram. This is a very powerful ability, because it gives the user the ability to focus on selected functional groups in a mixture of compounds.

Conclusion

Gas chromatography with infrared detection is a powerful tool for the elucidation of the structure of organic compounds in a mixture. It is complementary to GC/MS and is used to identify specific isomers and congeners of organic compounds. This method is greatly needed in the Cannabis industry to monitor the compounds that determine the flavor and the medicinal value of its products.

Dishonest Potency Testing In Oregon Remains A Problem

By Kelly O’Connor

9 Comments

Oregon, we have a problem.

Anyone with a search engine can piece together how much THC certain strains produce and what their characteristics are. Oh wait- there’s an app for that… or dozens, I lose count these days.

Nefarious lab results are rampant in our communityLet’s take one of my favorites, Dutch Treat; relaxing, piney and sweet with a standard production of 18-25% THC, according to three different reviews online. So, did I raise an eyebrow when I saw Dutch Treat on Oregon shelves labeled at 30% THC? Did I take it in to an independent, accredited lab and have it tested for accuracy? You bet your inflated potency results I did! The results? Disappointing.

Nefarious lab results are rampant in our community; it is hurting every participant in our industry affected by the trade, commerce and consumption of recreational cannabis.

“I have had labs ask me what I want my potency numbers to look like and make an offer,” says David Todd, owner and operations manager of Glasco Farms, a craft cannabis producer in central Oregon. “It’s insane- I want to stand behind my product and show through scientific fact that I produce a superior flower.”

But without enforcement of lab practice standards, producers are being pressured to play dirty. In her third year cultivating at a two-tier recreational cannabis farm, a producer who wished to remain anonymous sent me an email about the pressures she is up against to produce high THC strains:

“The only sure way to get my product on the shelf at a profitable price is with THC 25% or above. Not a lot of strains have that potential, but the market has plenty with 28% to 32% floating around so I have to go with the same labs as the rest of the independent farmers to get the best numbers I can. The lab I use … return(s) good numbers.”

Those “good numbers,” aka high THC %, are the driving force of sales. A strain tests at 20% THC and it sells for $1,000/lb. Then it tests at 25% THC, and sells for $1300/lb. You produce cannabis for sale- this is your business. And labs are telling you that they can manipulate samples and reports to make you more money. Everyone else is doing it. If you don’t, your product isn’t “good enough” to sell. What do you do?Labs should operate ethically.

It’s a vicious cycle perpetuated by lies, lack of enforcement resources, coercion and undereducation. We are all responsible. Yet, ask who the source of the problem is and everyone points fingers across the circle.

The consumers are uneducated about cannabis and only focus on THC. The dispensaries and budtenders should be educating them. Producers should take a stand and use an honest lab. Labs should operate ethically.

I repeat: Oregon, we have a problem.

It’s time to stop living in a land where Dutch Treat is hitting 30% THC. It’s time for everyone to demand auditing and ethics.

Laws have been set forth on how to sample, prep, test and report analyses for cannabis to ensure fair commerce, consumer health and public safety. But there’s a clear need to blind test the different labs, and for unbiased, third-party research and development.

As federal eyes turn to the Oregon to investigate black market activity, regulatory bodies are tightening their grip on licensees to maintain legal validity and avoid shut down.

The time to demand change and integrity is now.The crack-down began on August 23, 2018, when the OLCC investigated several prominent producers’ practices. Black market distribution incurred the harshest penalty; the OLCC revoked their wholesale license due to multiple violations.

“We want good compliant, law-abiding partners as OLCC marijuana licensees,” says Paul Rosenbaum, OLCC Commission Chair. “We know the cannabis industry is watching what we’re doing, and believe me, we’ve taken notice. We’re going to find a way to strengthen our action against rule breakers, using what we already have on the books, and if need be working with the legislature to tighten things up further.”

Trends in METRC data lay the foundation for truth, and it’s time to put it to use. “The Cannabis Tracking System worked as it should enabling us to uncover this suspicious activity,” says Steven Marks, OLCC Executive Director. “When we detect possible illegal activity, we need to take immediate steps …”

Potency fraud might not be at the top of the list for investigation, but labs and producers are breaking the law, and there will be consequences. ORELAP and OLCC have the right to investigate and revoke licenses of labs that are falsifying data and consumers can file claims with the Department of Justice.

The time to demand change and integrity is now.

A2LA Partners With ATACH

By Aaron G. Biros

No Comments

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.”

The Future of California’s Regulations: Q&A with Josh Drayton

By Aaron G. Biros

1 Comment

Josh Drayton, deputy director of the California Cannabis Industry Association, has an extensive career in local and state-level politics, with his origins in Humboldt County as a political organizer. As a coffee shop owner about ten years ago in Humboldt, he let city council candidates use his space for community engagement, which eventually steered him towards a career in politics. As a heavily involved resident of Northern California and an advocate in local and state matters, he came to understand cannabis as a strong economic driver for the region and beyond.

Drayton saw firsthand how local economies benefit from cannabis as a source of income, economic activity, and providing occupational opportunities for many families in Humboldt County. After running a handful of local campaigns in the Humboldt region, Drayton served as deputy director for a state senate campaign in Riverside.

Josh Drayton, deputy director of the CCIA

Towards the end of his tenure with the Democratic Party in California, the state legislature began working on medical cannabis regulations. “As we saw those regulations moving through, cities and counties began to ban cannabis throughout the state, which was a very unintended consequence,” says Drayton. “The goal was to put regulations forward that would create a framework for the industry to survive and function under, but they were not very fond of cannabis at the time. It was clear that we had a lot of work to do.” Politicians shying away from cannabis issues and a lack of real representation in the legislature for those stakeholders drove him to leave the state’s senate for the California Cannabis Industry Association (CCIA).

In January of 2016, he jumped on board with the CCIA as their deputy director. Ahead of the California Cannabis Business Conference, September 21-22 in Anaheim, we sit down with Drayton to hear his take on the future of California’s cannabis regulations.

CannabisIndustryJournal: Give us a quick update on the regulatory framework in California and the changes we should expect.

Josh Drayton: One of the biggest challenges that California has faced has been the reconciliation of medical regulations with adult use regulations. Although California had medical cannabis legalized in 1996, we did not get those regulations put forward until 2015. That was called the Medical Cannabis Regulation and Safety Act. That was approved by the state legislature and signed by the governor into law. It was created in the legislature. When Prop 64 passed, the Adult Use of Marijuana Act, in November of 2016, it was passed through by a voter initiative. Any time that a piece of legislation goes to the voters, it trumps any legislation or regulations written by the state legislature. The real work has been to reconcile these two pieces of legislation into one regulatory structure. With that being said, we saw the initial trailer bill, attempting to reconcile these regulatory structures. That trailer bill is meant to address the new framework. Currently, we are waiting for the second viewing of the updated trailer bill SB 94 with all current amendments. Then we are anticipating those in the next couple weeks and we will see the regulations that will affect all these changes by November.

CIJ: How strong will local and municipal control be in the future?

Josh: It is incredibly strong and it is meant to be. I will say that California is like its own country. In Northern California, what they are willing to accept is very different in comparison to Southern California. Every city and county still has the ability to fully ban adult use and they can create and draft their own ordinances and regulations as long as it doesn’t go above state requirements. They can craft an ordinance to fit the needs of their city or county. Lets say you are in a rural area, delivery services might be important for patient access. Some areas might not allow brick and mortar dispensaries, and all that control lies in the cities and counties.

CIJ: Will there be a dosing limit for patients buying infused products? What about for adult use?

Josh: For adult use, there is going to be a limitation. Every edible has a maximum potency of 10mg of THC. For example, a chocolate bar can have a maximum of 100mg [of THC] but must be perforated in to 10mg pieces.

We have been advocating for, and what has been a priority for CCIA, is a lift of any sort of limits on medical infused products. Many patients have a higher threshold or tolerance and they may need 100mg and we don’t want them eating an entire chocolate bar to get that. We are anxiously awaiting the new trailer bill to see if we have been able to lift that concentration limit.

CIJ: Some have said the first draft of lab testing rules is extreme and overreaching. Can you speculate how those have been modified?

Josh: The lab testing is a huge educational issue for the industry and regulators. No state right now has been able to fully analyze the effects of different pesticide levels for a product that is smoked. We are basing all of our standards currently on food consumption. A lot of testing labs are concerned they are unable to test at the state’s threshold for some of these contaminants and pesticides; the detection limits seem very low. The testing portion will take years to work out, I am sure we will remove and add different pesticides and contaminants to the list. But again, the data and research isn’t fully there. There is a big push across the board that we will be able to do more research and testing so that the future of regulations can reflect reality, and ensure that consumer safety is priority.

CIJ: What do you think of the lack of residency requirement? When Oregon lifted it, outside investors flocked to the market. How might that impact local, California ownership and smaller businesses?

Josh: Well I do think that is a concern across the board. That is something that cities and counties have been adding to their requirements for the matrix of items needed to get a license. I think there is a very gray area when looking at investors opposed to operators. At what threshold does an investor become an owner? And if that person is from outside the state, how will that reflect on the evolution of the industry? It is a concern. Keeping limitations on the size of outdoor cultivation might help limit folks from outside the state coming into that arena. After living in Humboldt County for years, and living next to Mom and Pop growers for a long time, I don’t want to see them displaced by businesses coming from another area. We have been doing this a long time and I believe we have the best operators in the world.

CIJ: How is the CCIA helping businesses gear up for changing regulations?

Josh: Well one of our biggest areas of focus is education. Educating our own industry is one of the biggest parts in making sure the industry will be successful in this regulated market. Our legislative committee will take a position of support or opposition, which goes to our board, and those recommendations go to the state. The manufacturing committee has worked very closely with Lori Ajax [director of the Bureau of Cannabis Regulation] and her office, to educate on a variety of areas, guiding the way for state departments on how to properly regulate the industry. We have a Diversity and Inclusion Committee, Retail/Delivery, Testing, Distribution and Agricultural committees; across the board our committees create white papers that we submit to the regulatory departments of the state. We take regulatory officials on tours of facilities to get a hands-on view of what they are regulating. They have been speaking with scientists and growers, who often have a better understanding of current industry standards. We see these tours as very helpful. We have brought groups of regulators from LA County, Long Beach, Napa, Alameda and many others on tours of Bay Area commercial manufacturing facilities, dispensaries and nurseries. They have a lot of questions and we want to make sure we are a resource for them. Putting folks in touch with the right people and, in moving forward with this process, in an educated manner. Cannabis is a foreign language to many people and I get that.

CIJ: If you have one recommendation for regulators, what would that be?

Josh: My recommendation to regulators: do not over-tax this industry. Do not make taxation the priority for regulation. Over-taxation will strengthen the illicit market and that is not the goal. We need to make sure the taxes are reasonable to encourage businesses to operate in this market, not in the illegal one. If cities decide to ban, they need to know they can be hubs for illicit activity. Cities with bans might draw the illicit market because illegal operators won’t have to pay taxes or license fees. It is a long play, but responsible taxation is the best path to draw people out of this illicit market. We want to help protect public safety and health, safe medicine, safe products and keep cannabis out of the hands of children.

Judging a Craft Cannabis Competition

By Aaron G. Biros

No Comments

Willamette Week, a Portland-based publication, is hosting the 2017 Cultivation Classic with Farma, Cascadia Labs, Phylos Bioscience and the Resource Innovation Institute on May 12^th. The event is a benefit for the Ethical Cannabis Alliance, an organization that promotes sustainability, labor standards and education surrounding the integrity and ethics of growing cannabis. Cultivation Classic is a competition for pesticide-free cannabis grown in Oregon, according to a press release.

While the event’s focus is on the competition, it is just as much a celebration of the craft cannabis community in Oregon. This year’s competition incorporates scientific collaboration like genetic sequencing for the winners by Phylos Bioscience and carbon accounting for all competitors. Keynote speakers include Ethan Russo, medical director of PHYTECS and Dr. Adie Po, co-founder of Habu Health. Congressman Earl Blumenauer, a prominent cannabis legalization advocate in Oregon, will also be speaking at the awards ceremony. You can check out the full schedule and speaker lineup here.

Raymond Bowser, breeder at Home Grown Natural Wonders, is a judge for this year’s Cultivation Classic. He speaks at cannabis conferences around the country and his business created a number of different strains, so he has experience with a myriad of growers and strains. “This time around everyone has really stepped up their game,” says Bowser. “The entries are noticeably better than last year.” When looking at the different samples sent to him, he sees a few key factors as most important in judging the quality. “What I am looking for is simple; a nice smell and a decent look, generally speaking,” says Bowser. “Aesthetics can tell you a lot about how it was grown, temperature changes and the overall care taken in cultivating and curing the flower.” For him, flavor, smell and aesthetics are the big variables to consider.

Those are factors that his company holds to high standards in their work, so he judges the samples based on the same variables. “It is what we strive for in our gardens and so far the samples I have tried are fantastic in that regard,” says Bowser. In other competitions that Bowser has judged in the past, they sent him between 40 and 60 strains to judge in seven days. “That is not conducive to a fair evaluation,” says Bowser. “Here, we are getting fourteen or so different strains, so we can sample one strain a day which is how I personally like to do it.”

Bowser is supportive of Cultivation Classic because of their emphasis on the craft industry. “We talk about craft cannabis and breeding craft cultivars at conferences around the country,” says Bowser. “With the rec industry growing so much, we see so many people cutting corners to save money, that it is refreshing to see growers take pride in the craft.” He also stresses the need for good lab testing and sound science in the trade. “I am big on lab testing; it is very important to get all the right analytics when creating strains,” says Bowser. “Cascadia is a solid choice for the competition; they have been a very good, consistent lab.” Emphasizing the local, sustainability-oriented culture surrounding the craft market, Bowser is pleased that this competition supports that same message. “We need to stay true to our Oregon roots and continue to be a clean, green, granola-eating state.”

Cascadia Labs is conducting the pesticide and cannabinoid analytics for all submissions and Phylos Bioscience will perform testing for the winners. According to Julie Austin, operations manager at Cascadia Labs, pesticide testing for the Oregon list of analytes was of course a requirement. “Some of the samples submitted had previous tests from us or from other accredited labs, but if they didn’t have those results we did offer a comprehensive pesticide test,” says Austin. The competition’s fee for submission includes the potency and terpenes analysis.

Jeremy Sackett, director of operations at Cascadia Labs, says they test for 11 cannabinoids and 21 terpenes. The samples are divided into groups of THC-dominant samples, CBD-dominant samples and samples with a 1:1 ratio of the two. “The actual potency data will be withheld from judges and competitors until the day of the event,” says Sackett. “We are data driven scientists, but this time we want to have a little fun and bring the heart of this competition back to the good old days: when quality cannabis was gauged by an experience of the senses, not the highest potency number.” The event will take place on May 12^th at Revolution Hall in Portland, Oregon.

2016 Year in Review: Why the Cannabis Industry Needs Resiliency

By Aaron G. Biros

No Comments

2016 was a tumultuous, but productive year for the cannabis industry. Larger companies began to take interest in the fledgling market, like Microsoft and Scotts Miracle-Gro. This year brought major innovations in technology like market data tools, advances in LED tech, efficient cultivation tech and patient education tools. The Supreme Court set an important precedent by shutting down a challenge to Colorado’s cannabis market.

Election Day brought a renewed sense of vigor to the market with voters in eight states legalizing forms of cannabis. California, Nevada, Maine and Massachusetts passed recreational cannabis measures, making legalization’s momentum seem exponential.

But November 8^th also gave Donald Trump the presidency, and his cabinet appointments, namely Sen. Jeff Sessions as Attorney General, gave many a feeling of uncertainty for the future of federal legalization. Adding insult to injury, the DEA repeatedly stood by their antiquated and ludicrous judgment for cannabis to remain a Schedule 1 narcotic.

A lot of the fervor surrounding public safety could be described as overdramatic or somewhat unwarranted. 2016 was the year of misinformation. Fake news spread like wildfire with people sharing stories like this or this that turned out to be very misleading or just downright false.

States with legal cannabis came under heavy public scrutiny and addressed problems like consumer education, public safety and lab testing. Pesticides became a highly publicized and persistent issue in a number of areas, with some states regulating it heavily and addressing public health concerns. Plenty of new rules were formed surrounding labeling and testing, with Oregon, Colorado and Washington experiencing some regulatory growing pains.

Those growing pains shed light on the need for regulators to craft rules that allow for changes, adding rules where necessary and getting rid of cumbersome rules that might thwart market growth. Rules need to be able to adapt as the industry grows, much like businesses need to adapt to a changing market climate to stay afloat. This is all the more reason why cannabis businesses need to make their voices heard and work with regulators to move things forward.

With so much uncertainty surrounding the future of legal cannabis in America, the word of the year for 2017 should be resiliency. In a social-ecological context, resiliency is “the capacity of a system to absorb or withstand perturbations and other stressors such that the system remains within the same regime, essentially maintaining its structure and functions. It describes the degree to which the system is capable of self-organization, learning and adaptation.”

Self-organization, learning and adaptation are three very important attributes of a resilient system. Without knowing what will happen when Trump’s cabinet takes the reigns of federal agencies, it is important to prepare for the unexpected. Adhering to standards like FOCUS allows cannabis businesses to prepare for unexpected events like recalls or product safety failures.

Those standards could also become the law down the road, as government officials often look to an industry’s voluntary consensus-based standards when deciding how to regulate it. In 2017, a number of state governments will embark on the heavy undertaking of writing the regulatory framework for legal cannabis.

2017 will bring opportunities and challenges to the cannabis industry. The industry’s rapid growth juxtaposed with political, economic and regulatory uncertainties create a climate that requires resilience to be built into the system at all levels. It is critical, now more than ever, that cannabis businesses build strong relationships with industry groups, advocacy groups and regulators to craft the institutional capacity and mutual trust needed to weather the uncertainty ahead.

The Cannabis Industry’s Pesticide Problem

Colorado regulators recalled roughly 65 batches of cannabis produced by two separate companies last Friday. Pesticide recalls plastered all over the news in the past few months have painted a picture of the cannabis marketplace to the public as unsafe and lacking crucial quality standards. The continued pesticide recalls in Colorado, along with poor safety standards in Washington, show the cannabis industry in an unfavorable light. The recalls include not only cannabis sold recreationally, but also medical cannabis, which should highlight a sense of urgency to deal with such a pervasive issue.

Because patients with weakened immune systems are seeking treatment with cannabis, it is the producer’s obligation to grow cannabis safely and without pesticides. That requires proper quality controls, pesticide use standard operating procedures, very robust lab testing and an overall push to protect consumer safety from both regulators and industry leaders.

The pesticides most commonly found in cannabis products include myclobutanil, a fungicide in Eagle 20, and avermectin, commonly found in Avid pesticides. The Pesticide Action Network lists both compounds as “bad actors” and as developmental or reproductive toxins.

Largely due to federal illegality, there are no EPA-approved pesticides for use in cannabis production, thus a lack of guidelines for states to follow in regulating pesticide use. As a result, states are working to write their own lists of approved pesticides.

Until very recently, Washington had no procedure for recalls of cannabis in place. “The LCB in Washington State has implemented emergency recall rules but more clarity on what types of pesticides are harmful is needed,” says Trek Hollnagel, co-founder of Dope Magazine and a chain of dispensaries in Seattle, WA. It is no secret that the Washington State Liquor Cannabis Board (LCB) poorly regulates cannabis labs.

Reports show immense variation in different labs’ results and rampant laboratory shopping. Dana Luce, co-founder of GOAT Labs, Inc., a cannabis-testing laboratory based in Vancouver, Washington, has been clamoring for a standardized recall procedure. “The state needs to take a much more proactive approach in monitoring laboratories,” says Luce. “Using blind testing or secret shoppers would give them the opportunity to catching those labs playing below board.” Luce also believes that retail outlets should absorb the cost of recalls, which could help prevent laboratory shopping just for higher potency test results.

In Washington, regulators rely on producers to self-report coupled with random inspections; furthermore they do not even require pesticide testing. Without a burden of proof placed on the producer or even the laboratory, it is hardly a regulated market.

Those producing cannabis with pesticides listed above should know they are violating the law. According to Comprehensive Cannabis Consulting (3C), “applying pesticides off label is a violation of state and federal law and could result in criminal and civil sanctions…”

In reality, the solution to this problem is not just a quick fix, but a multitude of corrective actions to move the cannabis industry forward. Nic Easley, chief executive officer of 3C, believes it starts with educating cultivators on using pesticides properly and good agricultural practices (GAP). “Many of the pest problems prompting the illegal use of pesticides are due to poor facility design, lack of cleanliness, over-fertilization and other general plant health issues,” says Easley. “All of those issues could be greatly reduced through education in GAP.”

Then comes regulator-industry collaboration, where all parties are constantly learning. “Regulators or independent third-party groups need to be performing on-site inspections, which cultivators need to participate in openly and transparently,” adds Easley. The Colorado Department of Agriculture (CDA) is actively working on this aspect by offering workshops aimed at helping producers get up to speed with worker protection standards.

“Adequate standards need to be applied across the board to labs, and ongoing proficiency testing needs to take place to ensure that a lab’s facility, processes and instruments are fully validated,” says Easley. So the problem is cannabis producers still using pesticides off label and if that continues, so will the recalls. It seems the solution involves industry-regulator collaboration, more robust laboratory systems and calibration methods and educating cultivators on good agricultural practices. Additionally, more state guidance is needed in the form of research for an approved list of pesticides on cannabis and a bigger push for regulation in the form of inspections and laboratory oversight.
