Broken Coast Cannabis Ltd., a cannabis business located on Vancouver Island, issued a voluntary recall of three cannabis lots due to the detection of pesticides. According to the safety alert published on Health Canada’s website, the voluntary Type III recall follows an inspection of the facility back in March of this year.
A Type III recall means those products are not likely to cause negative health effects. Sampling of those three cannabis lots found a cannabis oil product in July to contain low levels of Myclobutanil and Spinosad.
Upon further testing, a cannabis leaf sample was found to contain 0.017 parts-per-million of Myclobutanil. A third party laboratory confirmed the presence of that fungicide, leading them to recall three lots of dried cannabis sold between July and December of 2016, according to that safety alert.
Spinosad, an insecticide, and Myclobutanil, a fungicide, are not authorized for use with cannabis plants per the Pest Control Products Act, however they are approved for use in food production. The health risks of ingesting either of those two chemicals are well documented. “Health Canada has not received adverse reaction reports related to Broken Coast Cannabis Ltd.’s products sold affected by the recall,” reads the safety alert. “Health Canada recommends that any individual affected by the recall immediately stop using the recalled product and to contact Broken Coast Cannabis Ltd., at the following number 1-888-486-7579.”
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.
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:
THC and CBD amounts on the label must be the value calculated by a laboratory, plus or minus 5%.
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.
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.
Butanol, Propanol and Ethanol are no longer on the solvent list.
The maximum concentration limit for THC and CBD testing can have up to a 5% variance.
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.
The Oregon Health Authority (OHA) recently implemented a set of temporary rules effective through June 28th of this year with the goal to establish a set of regulations for cannabis testing by October 1st. An investigation by The Oregonian highlighted some of the previous problems with cannabis testing in the state.
The most impactful rule changes include The NELAC Institute (TNI) mandatory standards for laboratories that the Oregon Environmental Laboratory Accreditation Program (ORELAP) will use to accredit labs. Initial rules in the Oregon medical cannabis program, HB 3460 from 2013, did not specify accreditation rules for cannabis testing.
ORELAP currently performs accreditation for lab testing under the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act and the Safe Drinking Water Act. The new cannabis testing rules will give ORELAP the authority to accredit and regulate cannabis labs in the state of Oregon.
Rodger Voelker, Ph.D., laboratory director of OG Analytical in Eugene, OR, believes these rules are monumental in establishing legitimacy in cannabis testing. “These new rules have major repercussions mainly because they require not only getting accreditation, but maintaining it with very strict requirements,” says Voelker. “That also includes procedural guidelines that very carefully outline the quality of laboratory practices and establishes a set of criteria for method validation.”
Voelker notes that two of the biggest changes are in quality control and data management. “The documentation they require is very thorough and strict with the idea that any aspect of an analysis can be replicated,” adds Voelker. “This is a real win for us in my opinion because now we have an agency that can issue the appropriate credentials as well as have the authority to make punitive measures.”
The timeline for implementation with temporary rules allows state regulators to work with laboratories to perform accreditation and bring laboratories up to speed. According to Shannon Swantek, ORELAP compliance specialist, products that dispensaries sell in medical and recreational markets are required to be tested under the new rules and in the analyte lists by an ORELAP accredited laboratory, starting on October 1st.
Swantek’s job is to accredit cannabis labs to the TNI standards, which is essentially very similar to ISO 17025, just with more prescriptive measures and the ability to pair with state agencies to enforce rules after accreditation. “The timeline for accreditation is dependent on how ready the lab is and how compliant they are to the TNI standard already,” says Swantek. “The culture had gotten so fraudulent that the legislature felt Oregon needed some serious, more strict rules in place.”
One of the biggest changes coming to Oregon cannabis testing is the new sampling requirement. “An accredited laboratory employee must take the sample because sampling is where a lack of training or outright fraud is skewing results, which occurs when a grower brings in a sample not representative of the batch,” adds Swantek. Sample preparation methods will also be required to be more robust to meet the action limits of pesticide testing in particular, helping to identify lower levels like parts-per-billion, according to Swantek.
Reports were also lacking key information in the past. The new rules will require more information such as the procedure used, the analyst carrying it out, dilution factors and any other information you need to theoretically reproduce the result. This will result in more accurate labels on products.
Many are concerned that the new lab testing requirements will raise the price of testing too much. In reality, those current prices are not realistic for accurate data, which points to the rampant fraud that ORELAP is trying to eradicate. “The old rules were written in such an ambiguous way that the prices were set by laboratories without a proper quality program or even without proper instrumentation,” says Swantek.
The accreditation process will require particularly robust quality control systems in labs. “Accreditation to the TNI Standard means that lab quality systems will require a documentation system, training procedures, record keeping, personnel requirements, organization details, proof of no conflicts of interest and corrective actions if noncompliant,” adds Swantek. “We single out each method or procedure, look at their raw data and proficiency testing and determine if they are meeting the technical requirements.”
According to Voelker, other industries have learned to adjust their costs with stringent lab testing rules. “I get that no one wants to pay more for lab testing, but the reality is that joining the world of commodities comes with additional costs to ensure consumer safety,” says Voelker. These rule changes will undoubtedly bring more consistency to Oregon’s cannabis industry with accurate lab testing and help the OHA shed more light on issues surrounding consumer safety.
