Marijuana

Marijuana is the herbal form of cannabis, a plant used for its psychoactive effects as a recreational drug and as a medicine. Chemically, the major psychoactive compound in marijuana is delta-9-tetrahydrocannabinol. Typically, marijuana itself is smoked. Other derrivatives of the cannabis plant are ingested in other ways.
