Journal Club #32: Cannabis Strains, Cannabinoids, and Terpenes

Today on Journal Club, Dr. Jon Cachat look at a study in 2021 out of University of Colorado, Boulder in cooperation with Leafly that examines nearly 90,000 cannabis samples. Does Indica, Sativa, and Hybrid really mean anything in terms of psychoactive effects? Are cannabis strains labelled consistently in terms of cannabinoid and terpene content? We also talk about an app Dr. Jon is working on where users report effects of different brands of cannabis matched with cannabinoids and terpenes, called The Cannabis Diary. Plus we talk briefly about a Spanish company, KREI, that is working on a patent for genetically tracking cannabis strains to their origin.
