Marijuana (Cannabis)

Street terms for marijuana: grass, pot, weed, bud, Mary Jane, dope, indo, hydro.

Marijuana is a mixture of the dried, shredded leaves, seeds, stems, and flowers of the hemp plant, cannabis sativa. It is typically smoked in joints (hand-rolled cigarettes), blunts (cigars), pipes, or bongs (water pipes). The active ingredient in marijuana is THC, which is responsible for the potency and effects of marijuana. Over the past two decades, THC levels of marijuana in the United States have increased.

Commercial-grade marijuana contains parts of the marijuana plant such as stems and seeds that are not of high quality. "Sinsemilla", higher potency marijuana, contains only the leaves and buds of the cannabis plant, where THC is most concentrated.
