California Rolls Out Licensing For Cannabis Businesses

Last week, the Bureau of Cannabis Control issued the first licenses for California’s new market. The first license went to Moxie, a cannabis distribution company out of Lynwood.

As of the publication of this article, the Bureau, the state authority tasked with leading the regulation of the industry, has issued 43 temporary licenses. So far, four laboratories have received licenses, along with a number of retailers, distributors, microbusinesses in both medical and adult-use markets.

The labs to receive their temporary licenses so far are pH Solutions, Steep Hill Labs, Pure Analytics and ORCA Cannalytics. Judging by the number of temporary medical and adult-use licenses awarded so far, it appears the Bureau is trying to issue a similar amount for each sector, distributing the number of licenses between the two equitably.

You can find the list of licensees here, and search between the dates of 12/15/17 to 1/2/18 to get the most up-to-date list of licenses awarded. “Last week, we officially launched our online licensing system, and today we’re pleased to issue the first group of temporary licenses to cannabis businesses that fall under the Bureau’s jurisdiction,” says Lori Ajax, Bureau of Cannabis Control Chief. “We plan to issue many more before January 1.”

According to the press release, temporary licenses are only issued to applicants with prior local authorization in the form of a license or permit from the jurisdiction where the business is. Those licenses will become effective on January 1, 2018. The temporary licenses will work for 120 days, or May 1, 2018, after which businesses will need to have a permanent license to continue operating.

More than 1,900 users have registered with the Bureau’s online system, and more than 200 applications have been submitted, according to the press release.

The various regulatory bodies in California have worked diligently for months now to roll out proposed emergency regulations, setting strict requirements for manufacturers, growers, retailers and testing labs. Manufacturing regulations, including specific labeling, packaging and processing requirements, give a good snapshot of how regulators plan to move forward. Testing requirements could also be significantly firmer, with rules for documentation, sample sizes, sampling procedures, storage and transportation.

Yet when the adult-use sales become fully legal on January 1, 2018, those regulations will not be fully implemented.

Donald Land, a UC Davis chemistry professor and chief scientific consultant at Steep Hill Labs Inc., told The Associated Press, “Buyer beware.” There will be a six-month range where existing inventory will be allowed on the shelves, products that might not meet the standards of the new rules. So dispensaries will get half a year of sales before all products have to meet the new, stricter testing requirements.

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.
