 Developing sustainable nanotechnology applications for food and agriculture demands deeper understanding on the biological implications of nanomaterials, beyond the creation of novel functional properties. 
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.

Does irradiated cannabis still contain mold spores? In this deep-dive episode, Trevor and Kirk explore the science behind cannabis irradiation, fungal contamination, and the hidden risks of mycotoxins. Dr. Saji George and Mamta Rani from McGill University break down how gamma irradiation is used to sterilize cannabis—and why even this industry-standard sterilization may not eliminate all harmful fungal spores or toxins. They reveal that while irradiation significantly reduces fungal contamination, advanced testing still detected viable spores and residual mycotoxins in some cannabis legal products. For immunocompromised patients, even minimal exposure to spores or toxins can matter. We explore testing gaps, regulatory limits, workplace risks, and new biocontrol solutions to prevent contamination at the source. Listen now to understand how cannabis irradiation works — and where the cracks in the system may be.
