Does gamma irradiation destroy THC… or protect patients from dangerous mold?
In Part 2 of our exploration into irradiated cannabis, Trevor and Kirk wrap up their conversation with Dr. Saji George and Mamta Rani from McGill University about gamma radiation, fungal contamination, and the real risks of mycotoxins in medical cannabis. If you’ve ever wondered whether irradiation “ruins” cannabinoids or if mold in cannabis is actually dangerous — this episode tackles both.
We explore how gamma irradiation works at the molecular level — breaking down fungal DNA, reducing pathogen burden, and potentially degrading mycotoxins. But what about THC, CBD, terpenes, and flavonoids? Does irradiation damage the very compounds patients rely on? The answer is more nuanced than social media headlines suggest. As the researchers explain, it’s a risk-benefit equation: the possible reduction in cannabinoids versus eliminating dangerous fungal spores — especially critical for immunocompromised patients such as those undergoing chemotherapy or living with HIV.
We also discuss whether cannabis should be regulated like food, whether inhaled products deserve stricter mold standards, and what Health Canada may need to reconsider. For home growers, medical users, and industry professionals alike, this episode raises the question: Is irradiation enough for microbial safety — and is it being done right?
If you care about cannabis safety, medical standards, fungal contamination, or cannabinoid preservation, this is a conversation you need to hear.
Listen now to understand the science behind irradiation — and decide for yourself whether the benefits outweigh the risks.
