Episode 168: Is It Really "Bad Weed"? The Science and Data of CHS with Dr. Codi Peterson

Author: Tad Hussey July 16, 2026 Duration: 1:10:02
What happens when the very plant celebrated for curing nausea becomes the exact thing causing severe, uncontrollable vomiting? In this episode, I sit down with Pediatric Emergency Pharmacist, University Professor, and Cannabis Science Expert Dr. Codi Peterson to dissect his groundbreaking, landmark survey of over 1,100 patients suffering from Cannabinoid Hyperemesis Syndrome (CHS)—the largest study of its kind to date. Dr. Peterson shares the hard data from his newly published research to move past internet rumors and tackle the science of CHS head-on. Together, they explore why the common industry theory blaming "neem oil" or "pesticides" fails basic toxicological standards, how different consumption methods (like vaping versus smoking flower) drastically alter the timeline of symptom onset, and why women experience statistically longer, more severe vomiting episodes than men. Whether you are a cultivator, a healthcare professional, or a daily consumer, this episode offers an essential, evidence-based perspective on the limits of high-THC consumption and the path toward true harm reduction.

Tad Hussey, founder of KIS Organics, hosts the Cannabis Cultivation and Science Podcast, a deep and practical resource for anyone serious about growing plants organically. Rather than offering quick tips, Tad builds each conversation on a foundation of verifiable science, breaking down complex soil biology, plant physiology, and sustainable methods into understandable segments. He regularly brings in leading researchers, agronomists, and seasoned cultivators, creating a unique space where academic knowledge meets real-world, hands-on experience. You'll hear detailed discussions on everything from microbial inoculants and nutrient cycling to the nuances of light spectra and water quality, all through the lens of organic stewardship. This podcast is for gardeners, hobbyists, and professionals who are curious about the "why" behind their practices and want to move beyond conventional growing advice. It’s a thoughtful exploration of how to work with natural systems to cultivate healthier plants, focusing on foundational principles that apply broadly while delving specifically into cannabis cultivation. The dialogue is always evidence-based, cutting through industry trends to examine what truly works, making it an essential listen for those who believe that the best cultivation starts with understanding the science in the soil.
