A brief history of medical cannabis
Marijuana plants produce chemical compounds called cannabinoids. There are a number of cannabinoids, but the most commonly discussed are delta-9tetrahydrocannabinol (THC) and cannabidiol (CBD). THC produces psychotropic effects, but CBD does not, making it the preferred compound for medical use.
Cannabinoids are a modification of chemical found in the cannabis, or marijuana, plant.
Though first widely recognized in the 1990s as an effective cancer treatment to prevent tumor growth, cannabinoids have since been used for a range of diseases, including sleeping disorders, pain management, nausea, loss of appetite, anxiety, epilepsy, inflammation, and eating conditions relayed to chemotherapy. Relaxing federal regulations in the United States has spurred a pop-up industry of medical cannabis pharmacology companies.
