NEW CannMed Coffee Talk, we discuss Identifying the Skunk Genes in Cannabis! #shorts #cannabiseducation #growers
During our conversation, we discuss:
⦾ What volatile sulfur compounds (VSCs) are and why they give certain cannabis strains their skunky, garlicky smell
⦾ How Manny’s path from cannabis cultivator and award-winning edible chef led him into bioinformatics at Canimatrix
⦾ Why the GMO (“garlic mushroom onion”) cultivar was chosen as the ideal candidate for studying VSCs
⦾ How hidden Markov models were used to find candidate VSC genes by comparing cannabis proteins to garlic, onion, and other sulfur-producing plants
⦾ And more!

![What were some peaks/trends in the data that seemed informative in your CHS survey? - Codi Peterson
Dr. Codi Peterson is a pediatric pharmacist with over a decade of experience specializing in acute care and pediatric emergency medicine. He currently serves as a clinical pharmacist at Radys Childrens Health of Orange County, where he works night shifts in the Emergency Department and applies his expertise to optimize medication safety and therapeutic outcomes in children. Beyond the hospital, Codi is deeply committed to education and mentorship. He is an Associate Clinical Professor at the University of California, Irvine, where he teaches cannabis pharmacology and therapeutics, and a guest lecturer at OCEMT, instructing paramedics and firefighters in applied pharmacology.
He is also an active researcher on Cannabinoid Hyperemesis Syndrome (CHS), having led one of the largest patient surveys on the condition to date. At CannMed 26, Codi will share the results of that study in a presentation titled, “Through the Eyes of a Patient: Integrating Story and Science to Demystify CHS”.
During our conversation, we discuss:
- Defining CHS and explaining why it is difficult to research
- Cannabis use patterns among CHS sufferers
- Whether contaminants and pesticides play a role in developing CHS
- The prodromal phase and early warning signs of CHS
- Sex-based differences in CHS patients
- Understanding the biological mechanisms behind the development of CHS
- and more

![A New Cannabis Plant Pathogen or A By-product of Non-Glandular Trichomes? - Zamir Punja, PhD
Dr. Zamir Punja is a Professor of Plant Biotechnology at Simon Fraser University in Canada. His research interests include the etiology and management of plant diseases and the applications of plant biotechnology for disease management. Since 2018, his work has focused on cannabis, identifying and describing a range of previously unreported pathogens affecting the crop and evaluating various methods for disease management.
Zamir is CannMed regular, having presented at 5 previous events. His presentations are always a highlight of the event because they often feature stunning electron microscope images showing plant structures and pathogens up close. In fact, his CannMed 22 presentation about glandular trichomes has gotten more than 300,000 views on our YouTube page, making it the most viewed CannMed presentation.
Zamir will again present at CannMed 26, this time about non-glandular trichomes in a presentation titled Non-glandular trichomes in cannabis plants can secrete salts”.
During our conversation, we discuss:
- Non-glandular trichomes: What they are and what they do.
- How leaf spots, initially mistaken for disease, led to the finding that cannabis secrete excess fertilizer salts through these trichomes.
- Theories on why the plant would develop the ability to actively excrete excess salts.
- Practical guidance for cultivators on how to distinguish overfertilization from disease.
- Future research directions — comparing salt-tolerant vs. non-tolerant strains under varying salinity levels and exploring whether this mechanism explains cannabiss resilience in drought-prone, high-salt environments.
