Marijuana is a green or gray mixture of dried, shredded flowers and leaves of the hemp plant (Cannabis sativa). It is the most often used illegal drug in this country. All forms of cannabis are mind-altering (psychoactive) drugs; they all contain THC (delta-9-tetrahydrocannabinol), the main active chemical in marijuana. There are about 400 chemicals in a cannabis plant, but THC is the one that affects the brain the most.
Marijuana addiction is a
phenomenon experienced by more than 150,000 individuals each year who enter
treatment for their proclaimed addiction to marijuana. Marijuana addiction is
characterized as compulsive, often uncontrollable marijuana craving, seeking,

interest. Marijuana addiction could be defined as chronically making the firm
decision not to use marijuana followed shortly by a relapse due to experiencing
overwhelming compulsive urges to use marijuana despite the firm decision not
