Marijuana

What is Marijuana? A green or gray mixture of dried, shredded flowers and leavers of the hemp plant Cannabis sativa. Contains more than 400 chemicals, including most of the harmful substances found in tobacco. The active ingredient in marijuana is delta-9-tetrahydrocannabinol(THC), which is responsible for its mind altering effects. THC starts a series of cellular reactions that lead to the high that is experienced when smoking marijuana. The more THC, the more potent and dangerous the “weed”. Marijuana is usually smoked in a cigarette, pipe, or “blunt”, but also may be mixed in food or brewed as a tea.
