Marijuana belongs to a group of plants known as cannabis. All forms of cannabis contain mind-altering drugs because of its main active chemical delta-9-tetrahydrocannabinol (THC). Among the 400 chemicals in marijuana, THC is the most potent and affects the brain the most.
Marijuana is the most common and widely used illegal drug in many countries. Marijuana is sold as a mixture of dried shredded flowers and leaves of the plant. It is taken through smoking, chewed or steeped in tea.
Marijuana addicts show compulsive, often irrepressible craving for marijuana. Marijuana will consume the mind and body of the user. Effects of marijuana addiction range from a seemingly innocent increase in appetite to the killer disease lung cancer. Since marijuana dominates the mind, there are many fatal accidents connected to its use.
Bigger problems come because of over dosage of Marijuana. Manifestations include toxic psychosis, delusion, hallucinations, and loss of self-identification.
