Marijuana is identified by its two active ingredients or chemicals: THC and CBD. THC is the psychoactive chemical that affects how you feel by creating the “high.”
But getting high is not all that it’s good for. THC also has a wide range of medical benefits, and is commonly reported to relieve pain, nausea, and depression, among other things.
THC was first isolated in 1964 by an Israeli scientist named Dr. Raphael Mechoulam. Since then, many other cannabinoid compounds have been discovered.
