2016 Year in Review: Why the Cannabis Industry Needs Resiliency

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 8th 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.

Top Portable Vaporizer Unit

With so many units out there, we often get asked what’s the best vaporizer, and this year, what the best vaporizer is. If you are not familiar with how a vaporizer works, check out the wikipedia vaporizer page or our own vaporizing intro article for a good summary. We have done a lot of vaporizer reviews over the last year but there has never been a question as to which one is best. Along the same lines, we also frequently get asked what is the best cheap vaporizer, and what is the best portable vaporizer, and recently, what is the best vaporizer?

Most people in the vaporizer industry agree on the answers to these questions and time has proven that these models are here to stay as the most popular units for vaporizing. Obviously personal preferences can vary from person to person, but this can be a starting point and you can decide for your own based on the reviews.

The Best Vaporizer:Volcano Vaporizer

volcano7-900x450
The best vaporizer in the world is the $500+ Volcano Vaporizer. It is made in Germany and nobody dispute it’s quality. There are plenty of vaporizers on the market but if you want the best, the Volcano is what you get. It has never been contested, and we doubt it ever will. Quality comes with a price, and in this case the Rolls Royce of Vaporizers is the Volcano.

The Best Vaporizer For The Money aka the Best Cheap Vaporizer- Magic Flight Launch Box
magic-flight-launch-box-review-mflb-portable-vaporizer-vapoplants
There are plenty of mid-high range vaporizers that are a great deal in themselves, but we are talking the best vaporizer for the money and that usually doesn’t involve a higher end vaporizer. By far, the most popular cheap vaporizer is the Magic Flight Launch Box Vaporizer. For around $120, you can have a totally stealth vaporizer that fits in the palm of your hand and is portable. Because of it’s price combined with a killer warranty, this unit is actually one of the best selling vaporizers on the market for those who have a lower budget in mind. While you can’t expect BMW quality for a Kia price, it gets the job done and is night and day healthier than combustion smoking.

The Best Portable Vaporizer : Pax Vaporizer

ploom-pax-vaporizer-4
If you are looking for a high end portable vaporizer, your best bet right now is the brand new Pax Vaporizer which just came out a week ago. Made by a company based out of San Francisco, Pax is taking the Vaporizer World by storm right now because of its cool, modern, efficient design, along with it’s small size. With only two removable parts and a quick heat up time, the Pax honestly feels like it was designed by Apple.

Pennsylvania Opens Cannabis Licensing Applications

PA Secretary of Health Dr. Karen Murphy last week announced applications for growers and processors, while dispensary license applications will be available January 17, 2017. License applications will be accepted from February 20 through March 20, 2017. Governor Wolf signed the medical cannabis bill into law back in April of this year.

“We’ve reached an important milestone in the program with the release of permit applications on January 17, 2017,” says Secretary Murphy. The PA Department of Health will issue 12 licenses for growers and processors and 27 dispensary licenses, according to Secretary Murphy’s statement. “The decision for which counties will be issued permits in this first phase was determined by using the department’s medical data, as well as comments from more than 5,000 patients and nearly 900 potential grower/processors and dispensary applicants.”

According to the Philly Voice, the highly populated Southeast region of Pennsylvania will get ten dispensary permits, including three in Philadelphia, two in Montgomery County and one in Bucks, Chester, Berks, Delaware and Lancaster counties each. The state will fully implement its medical cannabis program by 2018, but a temporary program with ‘Safe Harbor guidelines’ was effective in May of 2016, essentially allowing access for patients in the mean time, while establishing preliminary regulatory compliance guidelines.

In last week’s statement, Secretary Murphy also stressed the importance of their Physician Workgroup in developing the regulations. “We cannot underestimate the role of physicians in making sure that patients can access medical marijuana,” says Secretary Murphy. “That’s why the involvement of physicians and health care professionals through our Physician Workgroup is vital to the successful development and implementation of Pennsylvania’s Medical Marijuana Program.” The Workgroup’s recommendations include establishing quality monitoring, training for dosage recommendations while addressing rural and urban access, education and delivery.

Potency Analysis of Cannabis and Derivative Products: Part 2

As mentioned in Part 1, the physiological effects of cannabis are mediated by a group of structurally related organic compounds known as cannabinoids. The cannabinoids are biosynthetically produced by a growing cannabis plant and Figure 1 details the biosynthetic pathways leading to some of the most important cannabinoids in plant material.

Potency figure 1
Figure 1: The biosynthetic pathway of phytocannabinoid production in cannabis has been deeply studied through isotopic labeling experiments

The analytical measurement of cannabinoids is important to ensure the safety and quality of cannabis as well as its extracts and edible formulations. Total cannabinoid levels can vary significantly between different cultivars and batches, from about 5% up to 20% or more by dry weight. Information on cannabinoid profiles can be used to tailor cultivars for specific effects and allows end users to select an appropriate dose.

Routine Analysis vs. Cannabinomics 

Several structurally analogous groups of cannabinoids exist. In total, structures have been assigned for more than 70 unique phytocannabinoids as of 2005 and the burgeoning field of cannabinomics seeks to comprehensively measure these compounds.¹

Considering practical potency analysis, the vast majority of cannabinoid content is accounted for by 10-12 compounds. These include Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabigerol (CBG), Δ9-tetrahydrocannabivarian (THCV), cannabidivarin (CBDV) and their respective carboxylic acid forms. The cannabinoids occur primarily as carboxylic acids in plant material. Decarboxylation occurs when heat is applied through smoking, vaporization or cooking thereby producing neutral cannabinoids which are more physiologically active.

Potency Analysis by HPLC and GC

Currently, HPLC and GC are the two most commonly used techniques for potency analysis. In the case of GC, the heat used to vaporize the injected sample causes decarboxylation of the native cannabinoid acids. Derivatization of the acids may help reduce decarboxylation but overall this adds another layer of complexity to the analysis² ³. HPLC is the method of choice for direct analysis of cannabinoid profiles and this technique will be discussed further.

A sample preparation method consisting of grinding/homogenization and alcohol extraction is commonly used for cannabis flower and extracts. It has been shown to provide good recovery and precision² ³. An aliquot of the resulting extract can then be diluted with an HPLC compatible solvent such as 25% water / 75% acetonitrile with 0.1% formic acid. The cannabinoids are not particularly water soluble and can precipitate if the aqueous percentage is too high.

To avoid peak distortion and shifting retention times the diluent and initial mobile phase composition should be reasonably well matched. Another approach is to make a smaller injection (1-2 µL) of a more dissimilar solvent. The addition of formic acid or ammonium formate buffer acidifies the mobile phase and keeps the cannabinoid acids protonated.

The protonated acids are neutral and thus well retained on a C18 type column, even at higher (~50% or greater) concentrations of organic solvent² ³.

Detection is most often done using UV absorbance. Two main types of UV detectors are available for HPLC, single wavelength and diode array. A diode array detector (DAD) measures absorbance across a range of wavelengths producing a spectrum at each point in a chromatogram while single wavelength detectors only monitor absorbance at a single user selected wavelength. The DAD is more expensive, but very useful for detecting coelutions and interferences.

Pesticide Detection in Cannabis: Lab Challenges and Why Less Isn’t Always More

Almost as soon as cannabis became recreationally legal, the public started to ask questions about the safety of products being offered by dispensaries – especially in terms of pesticide contamination. As we can see from the multiple recalls of product there is a big problem with pesticides in cannabis that could pose a danger to consumers. While The Nerd Perspective is grounded firmly in science and fact, the purpose of this column is to share my insights into the cannabis industry based on my years of experience with multiple regulated industries with the goal of helping the cannabis industry mature using lessons learned from other established markets. In this article, we’ll take a look at some unique challenges facing cannabis testing labs, what they’re doing to respond to the challenges, and how that can affect the cannabis industry as a whole.

The Big Challenge

Over the past several years, laboratories have quickly ‘grown up’ in terms of technology and expertise, improving their methods for pesticide detection to improve data quality and lower detection limits, which ultimately ensures a safer product by improving identification of contaminated product. But even though cannabis laboratories are maturing, they’re maturing in an environment far different than labs from regulated industry, like food laboratories. Food safety testing laboratories have been governmentally regulated and funded from almost the very beginning, allowing them some financial breathing room to set up their operation, and ensuring they won’t be penalized for failing samples. In contrast, testing fees for cannabis labs are paid for by growers and producers – many of whom are just starting their own business and short of cash. This creates fierce competition between cannabis laboratories in terms of testing cost and turnaround time. One similarity that the cannabis industry shares with the food industry is consumer and regulatory demand for safe product. This demand requires laboratories to invest in instrumentation and personnel to ensure generation of quality data. In short, the two major demands placed on cannabis laboratories are low cost and scientific excellence. As a chemist with years of experience, scientific excellence isn’t cheap, thus cannabis laboratories are stuck between a rock and a hard place and are feeling the squeeze.

Responding to the Challenge

One way for high-quality laboratories to win business is to tout their investment in technology and the sophistication of their methods; they’re selling their science, a practice I stand behind completely. However, due to the fierce competition between labs, some laboratories have oversold their science by using terms like ‘lethal’ or ‘toxic’ juxtaposed with vague statements regarding the discovery of pesticides in cannabis using the highly technical methods that they offer. This juxtaposition can then be reinforced by overstating the importance of ultra-low detection levels outside of any regulatory context. For example, a claim stating that detecting pesticides at the parts per trillion level (ppt) will better ensure consumer safety than methods run by other labs that only detect pesticides at concentrations at parts per billion (ppb) concentrations is a potentially dangerous claim in that it could cause future problems for the cannabis industry as a whole. In short, while accurately identifying contaminated samples versus clean samples is indeed a good thing, sometimes less isn’t more, bringing us to the second half of the title of this article.

Less isn’t always more…

Spiral Galaxy Milky Way
The Milky Way

In my last article, I illustrated the concept of the trace concentrations laboratories detect, finishing up with putting the concept of ppb into perspective. I wasn’t even going to try to illustrate parts per trillion. Parts per trillion is one thousand times less concentrated than parts per billion. To put ppt into perspective, we can’t work with water like I did in my previous article; we have to channel Neil deGrasse Tyson.

The Milky Way galaxy contains about 100 billion stars, and our sun is one of them. Our lonely sun, in the vastness of our galaxy, where light itself takes 100,000 years to traverse, represents a concentration of 10 ppt. On the surface, detecting galactically-low levels of contaminants sounds wonderful. Pesticides are indeed lethal chemicals, and their byproducts are often lethal or carcinogenic as well. From the consumer perspective, we want everything we put in our bodies free of harmful chemicals. Looking at consumer products from The Nerd Perspective, however, the previous sentence changes quite a bit. To be clear, nobody – nerds included – wants food or medicine that will poison them. But let’s explore the gap between ‘poison’ and ‘reality’, and why that gap matters.

FDAIn reality, according to a study conducted by the FDA in 2011, roughly 37.5% of the food we consume every day – including meat, fish, and grains – is contaminated with pesticides. Is that a good thing? No, of course it isn’t. It’s not ideal to put anything into our bodies that has been contaminated with the byproducts of human habitation. However, the FDA, EPA, and other governmental agencies have worked for decades on toxicological, ecological, and environmental studies devoted to determining what levels of these toxic chemicals actually have the potential to cause harm to humans. Rather than discuss whether or not any level is acceptable, let’s take it on principle that we won’t drop over dead from a lethal dose of pesticides after eating a salad and instead take a look at the levels the FDA deem ‘acceptable’ for food products. In their 2011 study, the FDA states that “Tolerance levels generally range from 0.1 to 50 parts per million (ppm). Residues present at 0.01 ppm and above are usually measurable; however, for individual pesticides, this limit may range from 0.005 to 1 ppm.” Putting those terms into parts per trillion means that most tolerable levels range from 100,000 to 50,000,000 ppt and the lower limit of ‘usually measurable’ is 10,000 ppt. For the food we eat and feed to our children, levels in parts per trillion are not even discussed because they’re not relevant.

A specific example of this is arsenic. Everyone knows arsenic is very toxic. However, trace levels of arsenic naturally occur in the environment, and until 2004, arsenic was widely used to protect pressure-treated wood from termite damage. Because of the use of arsenic on wood and other arsenic containing pesticides, much of our soil and water now contains some arsenic, which ends up in apples and other produce. These apples get turned into juice, which is freely given to toddlers everywhere. Why, then, has there not an infant mortality catastrophe? Because even though the arsenic was there (and still is), it wasn’t present at levels that were harmful. In 2013, the FDA published draft guidance stating that the permissible level of arsenic in apple juice was 10 parts per billion (ppb) – 10,000 parts per trillion. None of us would think twice about offering apple juice to our child, and we don’t have to…because the dose makes the poison.

How Does This Relate to the Cannabis Industry?

The concept of permissible exposure levels (a.k.a. maximum residue limits) is an important concept that’s understood by laboratories, but is not always considered by the public and the regulators tasked with ensuring cannabis consumer safety. As scientists, it is our job not to misrepresent the impact of our methods or the danger of cannabis contaminants. We cannot understate the danger of these toxins, nor should we overstate their danger. In overstating the danger of these toxins, we indirectly pressure regulators to establish ridiculously low limits for contaminants. Lower limits always require the use of newer testing technologies, higher levels of technical expertise, and more complicated methods. All of this translates to increased testing costs – costs that are then passed on to growers, producers, and consumers. I don’t envy the regulators in the cannabis industry. Like the labs in the cannabis industry, they’re also stuck between a rock and a hard place: stuck between consumers demanding a safe product and producers demanding low-cost testing. As scientists, let’s help them out by focusing our discussion on the real consumer safety issues that are present in this market.

U.S. Senators to Treasury: Protect Banking for Cannabis

On Wednesday, ten U.S. Senators from both sides of the aisle signed a letter pleading with the U.S. Treasury Department to help with banking for cannabis businesses, according to Lisa Lambert of Reuters. The letter seeks some form of protection for cannabis-friendly banks and credit unions, even those doing business with ancillary companies.

Notable signatories include Senators Elizabeth Warren (D-Massachusetts), Bernie Sanders (D-Vermont) and Jeff Merkley (D-Oregon). “Most banks and credit unions have either closed accounts or simply refused to offer services to indirect and ancillary businesses that service the marijuana industry,” states the letter. “A large number of professionals have been unable to access the financial system because they are doing business with marijuana [sic] growers and dispensaries.”

According to a spokesman, the Treasury Department’s Financial Crimes Enforcement Network will be addressing it. It is unclear exactly how Sen. Jeff Sessions, Trump’s attorney general nomination, would deal with cannabis-friendly states, let alone banking for them.

Many think Sessions would restrict access, ramp up federal crackdowns and make it difficult for cannabis businesses to grow. Once again however Jeff Sessions has not shared any plans on enforcing the Controlled Substances Act or cracking down on legal cannabis.

OHA Addresses Oregon Growing Pains, Changes Testing Rules

Last week, the Oregon Health Authority (OHA) published a bulletin, outlining new temporary testing requirements effective immediately until May 30th of next year. The changes to the rules come in the wake of product shortages, higher prices and even some claims of cultivators reverting back to the black market to stay afloat.img_6245

According to the bulletin, these temporary regulations are meant to still protect public health and safety, but are “aimed at lowering the testing burden for producers and processors based on concerns and input from the marijuana industry.” The temporary rules, applying to both medical and retail products, are a Band-Aid fix while the OHA works on a permanent solution to the testing backlog.

Here are some key takeaways from the rule changes:

Labeling

  • THC and CBD amounts on the label must be the value calculated by a laboratory, plus or minus 5%.

Batch testing

  • A harvest lot can include more than one strain.
  • Cannabis harvested within a 48-hour period, using the same growing and curing processes can be included in one harvest lot.
  • Edibles processors can include up to 1000 units of product in a batch for testing.
  • The size of a process lot submitted for testing for concentrates, extracts or other non-edible products will be the maximum size for future sampling and testing.

Sampling

  • Different batches of the same strain can be combined for testing potency.
  • Samples can be combined from a number of batches in a harvest lot for pesticide testing if the weight of all the batches doesn’t exceed ten pounds. This also means that if that combined sample fails a pesticide test, all of the batches fail the test and need to be disposed.

Solvent testing

  • Butanol, Propanol and Ethanol are no longer on the solvent list.

Potency testing

  • The maximum concentration limit for THC and CBD testing can have up to a 5% variance.

Control Study

  • Process validation is replaced by one control study.
  • After OHA has certified a control study, it is valid for a year unless there is an SOP or ingredient change.
  • During the control study, sample increments are tested separately for homogeneity across batches, but when the control study is certified, sample increments can be combined.

Failing a test

  • Test reports must clearly show if a test fails or passes.
  • Producers can request a reanalysis after a failed test no later than a week after receiving failed test results and that reanalysis must happen within 30 days.

The office of Gov. Kate Brown along with the OHA, Oregon Department of Agriculture (ODA) and Oregon Liquor Control Commission (OLCC) issued a letter in late November, serving as a reminder of the regulations regarding pesticide use and testing. It says in bold that it is illegal to use any pesticide not on the ODA’s cannabis and pesticide guide list. The letter states that failed pesticide tests are referred to ODA for investigation, which means producers that fail those tests could face punitive measures such as fines.

The letter also clarifies a major part of the pesticide rules involving the action level, or the measured amount of pesticides in a product that the OHA deems potentially dangerous. “Despite cannabis producers receiving test results below OHA pesticide action levels for cannabis (set in OHA rule), producers may still be in violation of the Oregon Pesticide Control Act if any levels of illegal pesticides are detected.” This is crucial information for producers who might have phased out use of pesticides in the past or might have began operations in a facility where pesticides were used previously. A laboratory detecting even a trace amount in the parts-per-billion range of banned pesticides, like Myclobutanil, would mean the producer is in violation of the Pesticide Control Act and could face thousands of dollars in fines. The approved pesticides on the list are generally intended for food products, exempt from a tolerance and are considered low risk.

As regulators work to accredit more laboratories and flesh out issues with the industry, Oregon’s cannabis market enters a period of marked uncertainty.

First Nevada Cannabis Lab Receives ISO 17025 Accreditation.

On December 7th, 374 Labs received ISO 17025 accreditation, becoming the first in Nevada to do so. The laboratory, based in Sparks, Nevada, is state-certified and now the only ISO 17025 accredited lab in the state, according to a press release. The laboratory is a member in both the Association of Commercial Cannabis Laboratories (ACCL) and the Nevada Cannabis Laboratory Association (NVCLA).

“As Nevada transitions into an adult-use cannabis market, it’s very important that the state’s cannabis testing laboratories are held to the highest standards – and ISO 17025 is a requirement of top testing laboratories in all industries from biotech to forensics in most major countries,” says Dr. Jeff Angermann, assistant professor in the University of Nevada, Reno’s School of Community Health Sciences.

According to the release, 374 Labs was a driving force behind Nevada’s round robin cannabis lab testing program. That program, administered by the Nevada Division of Public and Behavioral Health (DPBH) and the Nevada Department of Agriculture (NDA), sends cannabis samples to each state-certified cannabis lab for a full analysis, measuring the consistency in test results across labs. “In other states proficiency involves testing pre-prepared, purified samples and neglects the challenges of coaxing out delicate analytes from the complex array of compounds found in actual marijuana,” says Laboratory Director Jason Strull. “I commend the DPBH and NDA for facilitating such an advanced quality program.”

Also notable is the announcing of their partnership with Clean Green Certified, a third-party certification (based on USDA organic certification) for sustainable, organically based cannabis cultivation. “Nevada allows certain levels of pesticides like Myclobutanil on its certified marijuana, so we wanted a way for patients and consumers to able to distinguish marijuana that is grown using organic methods,” said Laboratory Director Jason Strull. According to Michael Seibert, managing member of 374 Labs, they have already started performing inspections for the third-party certification and the first facility inspected was Silver State Trading in Sparks, Nevada (certified for both production and cultivation).

Recount Underway for Maine Cannabis Legalization Initiative

On Election Day in Maine, voters were heavily divided on Question 1, a ballot initiative that would legalize recreational cannabis. Voters passed the initiative, but with a very narrow margin, according to a WGME article.

Out of almost 760,000 ballots, Question 1 passed by a margin of only 4,073 votes, roughly 50.2% in favor and 49.8% against. Maine Secretary of State Matt Dunlap says State Police is responsible for collecting the physical ballots and bringing them to Augusta. Dunlap’s office is coordinating with volunteers to recount each vote by hand.

Dunlap is quoted saying there would have to be significant vote changes in every town to indicate any discrepancies in the polling. He says the state can recount up to 25,000 votes a day, but with the upcoming holidays, the recount will continue into 2017.

According to International Business Times, Gov. Paul LePage, who is a cannabis legalization opponent, has said he would delay the process of legalization even if the measure passed. He also said he would speak with president-elect Donald Trump regarding the enforcement of federal cannabis prohibition. Governor Lepage said if the Trump administration embraces states with legal cannabis then he too would honor the voters’ wish to legalize recreational cannabis.

Steep Hill, ACCL Find Pesticides in Over 50% of Cannabis Samples

On Election Day, voters in California passed Proposition 64, establishing a recreational cannabis market and regulatory environment. While the state won’t issue the first licenses under the new regulatory scheme until 2018, the medical cannabis industry is already well established.

Steep Hill Labs, Inc., based in Berkeley, California, found in October that 84.3% of samples submitted tested positive for pesticide residue, according to a press release. The announcement came before Election Day, but is particularly eye opening given the massive new market created overnight by Prop 64.rsz_steephill_lab_images_25_of_415_copy

Particularly concerning is their detection of Myclobutanil, which was found in more than 65% of samples submitted to the lab. According to the press release, when Myclobutanil is heated (i.e. smoked or vaporized), it is converted to Hydrogen Cyanide, which is extraordinarily toxic to humans and can be fatal in higher doses.

According to Reggie Gaudino, Ph.D., vice president of science, genetics and intellectual property at Steep Hill, their more recent study shows they detected pesticides in roughly 70% of the samples they received and 50% of those contained Myclobutanil. Gaudino says that up to a third of those samples would have failed under Oregon’s regulatory standards.

If a lab test were failed, it would contain pesticides at or higher than the required action level. Oregon’s action level, or the measured amount of pesticides in a product that the OHA deems potentially dangerous, for Myclobutanil is 0.2 parts-per-million (PPM). Steep Hill’s instrumentation has a method detection limit down to the parts-per-trillion (PPT) level, which is a more precise and smaller amount than Oregon’s action level.

“Those in the cannabis community who feel that all cannabis is safe are not correct given this data – smoking a joint of pesticide-contaminated cannabis could potentially expose the body to lethal chemicals,” says Jmichaele Keller, president and chief executive officer of Steep Hill. “As a community, we need to address this issue immediately and not wait until 2018.”

Potentially harmful pesticides, and specifically Myclobutanil, have been detected in Colorado and Washington’s recreational markets on a number of occasions, proving this is a widespread issue. Steep Hill’s release suggests that California regulators take a look at Oregon’s pesticide regulations for guidance when developing the regulatory framework.

What’s even more troubling is that not all laboratories have or had the capability of detecting pesticides at sufficiently low levels and because of this, other labs had significantly lower rates of pesticide detection, suggesting possible inconsistencies in testing methods, instrumentation, sample preparation or other variations. During a 30-day period in late September and early October, Steep Hill found, using publicly available data, or data from contracted testing, that other labs were only reporting between 3% and 21% pesticide detection.

It is important to note that those samples were not identical and there could be a great degree in variation on the quality of samples sent to different laboratories, so it is not an entirely accurate comparison. Steep Hill does however detect pesticides down to the parts-per-trillion level, whereas many common methods for detecting pesticides look at the parts-per-billion level.

Reggie Gaudino says the Association of Commercial Cannabis Laboratories (ACCL) is using this data to work with Steep Hill and a number of other labs to address these issues. “As a member of the ACCL, and after discussion with ACCL, we have agreed that all future discussion of this issue should not include laboratory names, as this is about educating the industry in general, and making sure all members of the ACCL are developing the best possible methods for detecting pesticides,” says Gaudino. “The ACCL has responded to this data, by inquiring on a larger, industry-wide basis, which represents a better picture of the issue, rather than only in California’s still-technically unregulated market.” The important message is this is a major issue that needs addressing urgently. “As such, the troubling issue remains, across the larger ACCL membership, there is still detection of pesticides in at least 50% of the cannabis being tested.”

ACCL logoAccording to Jeffrey Raber, Ph.D., president of the ACCL, the industry is experiencing a pesticide problem, but it is very difficult to quantify. “It is fair to say that around 50% of the cannabis being tested contains pesticides, but we really don’t know that exact number until a much more comprehensive statistical analysis is performed,” says Raber. “We agree this is a big problem and that it needs to be addressed, but we are not sure just how big of a problem it really is.” With so much variation in labs in a state where not everyone is required to test products, it is very difficult to pin down how consistent lab results are and how contaminated the cannabis really is. “If all of the labs had the same methodology, samples and shared statistical analyses for a real study then we can look at it closely but it seems we are a ways off from that. I can say confidently however that this is a pretty significant problem that needs addressing.”

Still, Steep Hill detecting pesticides in a majority of their samples and some labs finding as little as 3% should raise some eyebrows. “Unfortunately, our recent study discovered that 84.3% of the samples assessed by our triple quadrupole mass spectrometer contained pesticides,” says Keller. “As of today, this tainted product could be sold in most dispensaries throughout the state of California without any way of informing the patients about the risks of pesticide exposure.”

These findings could mean potentially enormous health risks for medical and recreational cannabis consumers alike, unless regulators, labs and growers take quick action to address the problem.
