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.
