Dr. Markus Roggen is a chemist, professor, cannabis researcher and founder & CEO of Complex Biotech Discovery Ventures (CBDV). Founder & CEO of Ascension Sciences (ASI), Tomas Skrinskas has been at the leading edge of transformative healthcare technologies, including computer assisted surgery, surgical robotics and genetic nanomedicines, for over 15 years.

Leading researchers from the cannabis industry – Dr. Markus Roggen (Complex Biotech Discovery Ventures) and Tomas Skrinskas (Ascension Sciences) – highlight the challenges facing the industry’s current compliance testing standards and the opportunities emerging from the latest developments in nanotechnology and advanced analytical testing. Here are the key insights from the discussion. 

What are the current compliance testing requirements for cannabis products? Are they sufficient in ensuring safety and quality?

In the current landscape, Canada’s compliance testing requirements are clearly laid out in the form of guidance documents. Specifically, for pesticide testing, cannabinoid concentration content in products, heavy metals, etc. Compliance testing can be roughly divided into two categories: 1) establishing the concentrations of wanted compounds, and 2) ensuring that unwanted compounds do not exceed safety limits.

In the first category, cannabinoids and terpenes are quantified. Their presence or absence is not generally forbidden but must stay within limits. For example, for material to be classified as hemp, the THC concentration cannot exceed 0.3 %wt., or a serving of cannabis edible should contain below 5 mg of THC. The second category of compliance testing focuses on pesticides, mold and heavy metals. The regulators have provided a list of substances to test for and set limits on those.

Are those rules sufficient to ensure safety and quality? Safety can only be ensured if all dangerous compounds are known and tested for. Take for example Vitamin E acetate, the substance linked to lung damage in some THC vape consumers and the EVALI outbreak. Prior to the caseload in the Fall of 2019, there were no requirements to test for it. It’s not only additives that are of concern. THC distillates often show THC concentrations of 90% plus 5% other cannabinoids. What are the last 5% of this mixture? Currently, those substances have not been identified. Are they safe? There is no concrete way to determine that.

The aforementioned guidelines have the best intentions, but do not adequately address two key obstacles the industry is currently facing: 1) what happens in practice, and 2) what can easily be audited? Making sure people follow the requirements is the challenge, and it comes down to variability of the tests. Testing has to happen on the final form of the product as well as every “batch,” but there is little guidance on how that is defined. With so much growth happening in the industry, how are these records even tracked and scrutinized?

And finally, there’s the question of quality. How do you define quality? Before establishing quantifiable quality attributes, it can’t be tested.

If compliance testing is insufficient, then why aren’t more cannabis companies testing beyond Health Canada’s requirements?

Compliance testing has always been focused on the end product, THC and CBD levels, and consumer safety. As long as cannabis companies are testing to determine this, doing further testing means added costs to the producer. There is a rush to get cannabis products to the new market because many consumers are eager to buy adult use products such as extracts or edibles, and quality is not the biggest selling point at this very moment.

However, there are unrealized advantages to advanced analytical testing that go beyond Health Canada’s requirements and that offer greater benefits to cannabis producers and product developers. Producers often see testing as an added cost to their production that is forced upon them by the regulators and will only test once the product is near completion. For cannabinoid therapeutics and nutraceuticals, advanced analytical testing is critical for determining the chemical makeup and overall quality of the formulation. This is where contract researchers, such as Ascension Sciences, come in to offer tests for nanoparticle characterization, cannabinoid concentration, dissolution profiles and encapsulation efficiency.

A lack of budget and awareness have prevented cannabis companies from advanced analytical testing. However, testing that goes beyond lawful requirements is an opportunity to save money and resources in the long term. This is where companies, like Complex Biotech Discovery Ventures (CBDV), offer in-process testing that provides a deep characterization and analysis of cannabis samples during every stage of product development. If tests are conducted during production, inefficiencies in the process are revealed and mistakes are spotted early on. For example, testing the spent cannabis plant material after extraction can verify if the extraction actually went through to completion. In another case, testing vape oil before it goes into the vape cartridges and packaging allows producers to detect an unacceptable THC concentration before they incur additional production costs.

Which methods are the most successful for cannabis testing?

The most effective method is the one that best determines the specific data needed to meet the desired product goal. For example, NMR Spectroscopy is paramount in assessing the quality of a cannabis sample and identifying its precise chemical composition.

HPLC (liquid/gas chromatography) is the most precise method for quantifying THC, CBD and other known cannabinoids. However, if a cannabis extractor wants to quickly verify that their oil has fully decarboxylated, then an HPLC test will likely take too long and be too expensive. In this case, IR (Infrared Spectroscopy) offers a faster and more cost-effective means of obtaining the needed data. Therefore, it ultimately depends on the needs of the producer and how well the testing instruments are maintained and operated.

What’s next in analytical testing technology? What are you working on or excited about?

In terms of compliance, regulations to standardize the testing is the hot topic at the moment. For nanotechnology and nanoparticles, the big question now is what is known as the “matrix” of the sample. In other words, what are the cannabinoids, and what else is in the sample that’s changing your results? The R&D team at Ascension Sciences is in the process of developing a standardized method for this to combat the issues mentioned earlier in the interview.

Ascension Sciences is also excited about characterizing nanoparticles over time to determine how cannabinoids are released and how that data can be transferred or made equivalent to consumer experiences. For example, if a formulation with quicker release, faster onset and better bioavailability is found in the lab, product development would be more efficient and effective when compared to other, more anecdotal methods.

At CBDV, the team is working on in-process analytical tools, such as decarboxylation monitoring via IR Spectroscopy and NMR Spectroscopy. CBDV is also looking at quantifying cannabis product quality. The first project currently in motion is to identify and quantify cannabinoids, terpenes, and other compounds present when vaping or smoking a joint using a smoke analyzer. 

A lack of budget and awareness have prevented cannabis companies from testing beyond what’s required by Health Canada. Compliance testing is designed to ensure safety, and for good reason, but it is currently insufficient at determining the quality, consistency and process improvements. As the above factors are necessary for the advancement of cannabis products, this is where further methods, such as advanced analytical testing, should be considered.

CannaSafe Accredited to ISO 17025

According to a press release sent out last week, Perry Johnson Laboratory Accreditation, Inc. announced the accreditation of CannaSafe Labs to ISO/IEC 17025. CannaSafe is based in Van Nuys, California and provides a number of different testing services, including full regulatory compliance testing for the state’s requirements.

CannaSafe was allegedly the first to break the news about vaping health issues caused by EVALI, the lung condition responsible for the 2019 vape crisis. According to the press release, they provided testing data that proved black market vapes contained dangerous chemicals, likely including vitamin E acetate, the chemical that the CDC says is linked to EVALI.

CannaSafe say they have plans to expand into a number of states beyond California. They are also planning to build a facility dedicated to CBD testing to meet market needs in the near future.

Judge Dismisses Claims in Vaping Illness Lawsuit

By Aaron G. Biros

In September of 2019, Charles Wilcoxen fell seriously ill after vaping cannabis oil from a cartridge. Just days after he began experiencing symptoms he was hospitalized and later diagnosed with lipoid pneumonia, the mysterious lung illness now known as EVALI associated with the 2019 vape crisis.

Wilcoxen spent three days in the hospital and ever since he was diagnosed, he has been unable to exercise, return to work full time or even play with his daughter. Attorneys for Herrmann Law Group representing Wilcoxen filed a product liability lawsuit, Wilcoxen v. Canna Brand Solutions, LLC, et al., in Washington State Court, naming six cannabis companies as defendants: Canna Brand Solutions, Conscious Cannabis, Rainbow’s Aloft, Leafwerx, MFused and Janes Garden.

This image came from the complaint filed, alleging that Mr. Wilcoxen believes this was a CCELL product.

This case was allegedly the first lawsuit in the wake of the 2019 vape crisis. The Vanderbilt University Law School Blog has a very comprehensive post on this case that has the original complaint and a lot of information on the lawsuit.

Canna Brand Solutions, the primary defendant named in the complaint, is a packaging supplier and distributor for CCELL vaping products (heating elements, pens and batteries) in the state of Washington. The complaint alleges that Wilcoxen believes he used a CCELL vape. CCELL is a Chinese company, which makes it notoriously difficult to pursue legal action against them, hence why Canna Brand Solutions was listed as a defendant instead.

On August 31, 2020, Judge Michael Schwartz dismissed all claims against Canna Brand Solutions. “All claims asserted by Plaintiff against Canna Brand in the above-mentioned matter shall be voluntarily dismissed without prejudice and without costs or fees to any of the parties to this litigation,” Judge Schwartz says in the dismissal. Judge Schwartz dismissed the case without prejudice, meaning it could be brought to the court again should the plaintiff’s attorneys decide to do so.

With the allegations against Canna Brand Solutions focusing on CCELL products, it seems that the case was dismissed largely due to a lack of evidence connecting exactly which product resulted in the illness, as well as the lack of culpability for a distributor of products they did not manufacture.

These are the vape cartridges that Mr. Wilcoxen purchased

Daniel Allen, founder and president of Canna Brands Solutions, claims that the product mentioned in the complaint did not come from his company. “We stand by our high quality and customizable CCELL vaporization products,” says Allen. “We feel vindicated in this case by the judge’s decision, which shows the claims against our company and products were completely unfounded from the beginning.”

He also added that the quality and safety of the products they distribute is their highest priority. “The product in question involved in this case did not come from Canna Brand Solutions,” says Allen.

Wilcoxen’s illness and subsequent long-term lung injury is extremely unfortunate. Thousands of people have been hospitalized and 68 deaths have been confirmed by the CDC. The CDC is still calling the illness EVALI (e-cigarette, or vaping, product use-associated lung injury). According to the CDC, there is no real known cause of EVALI, but they have found that vitamin E acetate is “strongly linked” to the outbreak. Knowing that, it is entirely possible that Mr. Wilcoxen’s illness was a result of one of the cannabis products he consumed, just most likely not anything that came from Canna Brand Solutions. A closer look at the contents with an independent lab test of the THC oil he consumed could shed some more light on what exactly caused the illness.

I would venture to guess that one of the products he consumed did have vitamin E acetate. Because the case was dismissed without prejudice, it could be brought to the court again if, say, Mr. Wilcoxen’s attorneys were to obtain more evidence, such as an independent lab report showing vitamin E acetate in the contents of one of the products he consumed. If Mr. Wilcoxen’s attorneys can figure out which product actually contained vitamin E acetate, perhaps the lawsuit could get a second shot and Mr. Wilcoxen could have a greater chance at getting some long-overdue and much-deserved restitution.
