Cannabis Contaminants

Cannabis Testing Gone Wrong? (IV) feat. Kyle Boyar

Do we even test for the right things?

Now that medical and adult-use cannabis programs have been around for some time, and with them mandated lab testing of products – we have a lot of data that we can begin to review in order to assess how well we are managing the quality of cannabis in the market.

In this episode we are joined by microbiologist and analytical technologist Kyle Boyar to confront the idea that there may be some things that regulators require testing for that will almost never show up in a sample, while there are certain toxins that show up more often than we might expect which are NEVER required for testing in any state in the country.

What’s going on? Let’s dive in and find out!

Cannabis Testing Gone Wrong? (Part III) feat. Dr. Josh Swider of Infinite Chemical Analysis Labs

Continuing our series on the issues facing the Cannabis testing industry, we sit down with Josh Swider of Infinite Chemical Analysis Labs to discuss the ways that he and his lab have felt the effects of potency inflation and lab shopping over the past several years. One by one Josh has watched clients disappear after complaints that his THC potency numbers were not high enough compared to his competitors. This is a story all too familiar to most labs that have ever operated in the space. Eventually the requests to boost THC results became much more direct as clients started offering bribes including outright briefcases full of cash. When he denied these advances, he began receiving death threats.

In an effort to understand just how bad the problem was, Josh and his team began collecting products off the shelf and testing them in the lab to see how the results compared to the original test results on record for the product. The results were alarming. Not only did he find evidence of potency fraud, but he also ended up finding evidence of various contaminants in products that somehow originally tested “clean.”

In this episode Josh and I take time to discuss his journey, how the industry has gotten into the situation it is in, and some potential solutions for moving the industry in a positive direction.

Cannabis Testing Gone Wrong (Part I) with Yasha Kahn of MCR Labs

This is the first of a series of conversations with lab owners and industry experts revolving around the topic of fraud, mismanagement, and poor regulations facing Cannabis testing labs. With issues ranging from THC potency inflation, under-reporting of contaminants, perverse incentive structures promoted by regulations, market manipulation, and more – this series dives deep into a very controversial issue to try to understand the problem at its foundation and find meaningful and practical solutions forward to restore trust and bring greater transparency to the Cannabis industry.

Yasha Kahn is one of the co-founders of MCR Labs and spends much of his time diving into data. Over the past several years, Yasha has been on a mission to collect publicly available Cannabis testing data and make it accessible to the industry in hopes of promoting fruitful research, discussion, and regulatory changes to positively impact the industry. In this episode we dive into some of the data that Yasha has gathered and start to unpack the story that it tells.

Standards: The Final Frontier? ASTM Intl’s Effort to Standardize the Cannabis Industry with Darwin Millard (The Spock of Cannabis) | BTS 83

In this behind-the-scenes conversation I beam aboard the USS Cannabis starship to join “The Spock of Cannabis” Darwin Millard to talk about ASTM International’s efforts to bring the planet together to develop unifying standards for the Cannabis industry. In this conversation we talk about why the development of international quality standards is critical, how ASTM’s collaborative open-door process of standard development is unique compared to how other organizations or government agencies develop standards, and how everyone with any interest in Cannabis has been invited to join the table to lend a voice and help drive the future of the international Cannabis industry.

What’s In a Toke? Exploring the Chemistry of Cannabis Smoke and More with Dr. Riley Kirk | BTS #79

Why does smoking Cannabis deliver unique effects compared to vaping or ingesting Cannabis? Why are social media platforms banning Cannabis educators from talking about the science of Cannabis? We have questions!

In this behind-the-scenes episode I sat down with Dr. Riley Kirk (@cannabichem) from Real Isolates, the company behind the Cannabis smoke extract product called Smokenol, to talk about the chemistry of Cannabis smoke (and lots of other cool natural products science!). In this conversation we discuss some of the unique cannabinoids that show up in Cannabis smoke and what Dr. Kirk has learned during her time studying the transformations of cannabinoids like CBD.

We also discussed her struggle to share Cannabis science education with the world due to the antagonistic nature of social media toward Cannabis content. Dr. Kirk has been shadow banned and de-platformed from social media sites like Instagram and TikTok for discussing basic Cannabis science and cannabinoid pharmacology. We dive into why these issues have real-world adverse effects for anyone curious about Cannabis and what Cannabis educators should know before they rush to their Reels or Stories to talk about Cannabis.

The conversation rounds off with a dive into Dr. Kirk’s love for plants where we talk about her favorite non-Cannabis medicinal plants and the exciting things we can learn when we apply the lens of Cannabis science to other natural products.

Catching Up with Murphy Murri on Benzene, Medusa Stones, and Owning the Quality of Your Lab | BTS #75

In this behind-the-scenes episode we caught up with Murphy Murri for an extended discussion about the current state of the Cannabis industry, extraction supply chain quality issues, medusa stones, mushroom extraction and more.

Medusa stones are concentrated lumps of cannabinoids that, rather than having a clear “diamond” appearance, has a chalky appearance. And like you might expect, the “diamond” disintegrates after being handled, turning into a sticky, chalky mess. So what causes the medusa stone phenomenon in Cannabis extracts? During this conversation, Murphy breaks down the phenomenon and the controversy surrounding the hunt for the cause behind these disappointing creations.

Due to some technical difficulties on the day of recording, this discussion was recorded on Zoom instead of our usual platform, resulting in some compromised audio quality.

Delta-8-THC and Other Obscure Cannabinoids | Narcotica #63

Recently I spoke with Troy Farah on the podcast Narcotica all about cannabinoid science, delta-8-THC, issues around vaping and legalization, and more! Thanks to the team at Narcotica for allowing us to share this episode! I hope you enjoy! Stay curious, and take it easy.

About this Episode of Narcotica:

“Nearly half the U.S. population now have access to adult-use cannabis. Marijuana is a medicine, if it’s cultivated or extracted right, and millions of people find relief or pleasure from this fantastic plant. But as legalization accelerates, regulations have struggled to keep up. Most experts and maybe many consumers would agree that cannabis is not well regulated or could use some improvements.

Meanwhile, new cannabinoids like delta-8-THC, THC-O and more are hitting the streets, licit and illicit. This is a rapidly changing environment, which is far beyond THC and CBD, the two most well-known drugs in marijuana. It leaves a lot of questions: Are these ‘new’ cannabinoids safe? What do they do in the body? What about vaping them?

Narcotica co-host Troy Farah speaks with Jason Wilson of Medford Oregon, host of the Curious About Cannabis podcast, and author of the book of the same name, which can be found at CACpodcast.com. Jason is a biologist and science educator that has been studying the biochemistry of the cannabis plant and cannabis-derived products for nearly a decade. Jason has done work with groups like the International Institute for Cannabinoids (ICANNA) and serves as a member on the board of directors for the Oregon Cannabis Education and Resource Center.
