What is Marijuana?

Marijuana is one of the names given to the Cannabis sativa plant when it is used as a drug. Marijuana is often called pot, grass, reefer, Mary Jane or MJ.  The active ingredient in marijuana is tetrahydrocannabinol or THC.

Marijuana may be smoked as a cigarette, in a pipe, in a blunt, or using a vaporizer. It may be consumed as a tea or in food.  Marijuana is a Schedule 1 Controlled Substance.  The use and legalization of marijuana is a controversial issue and there are states that have legalized marijuana for both medical and/or recreational use.  Marijuana is illegal in Iowa.
