NPR: FDA Green Lights Marijuana-Based Pharmaceutical Drug

The U.S. Food and Drug Administration has approved a marijuana-derived drug for the treatment of two rare and serious forms of epilepsy, Lennox-Gastaut syndrome and Dravet syndrome, that begin in childhood but can persist in adulthood.

The drug is made from purified cannabidiol, or CBD, a compound found in the cannabis plant. The drug will be marketed under the brand name Epidiolex.
