What is Marijuana? Marijuana is a green, brown or gray mixture of dried, shredded leaves, stems, seeds and flowers of the hemp plant Cannabis sativa Sinsemilla, hash/hashish (resinous form) and hash oil (sticky black liquid) are stronger forms of marijuana

How does Marijuana work? The main active chemical in marijuana is THC (delta-9 -tetrahydrocannabinol). It is a psychoactive ingredient When marijuana smoke is inhaled, THC rapidly passes from the lungs into the bloodstream and is carried to the brain and other organs throughout the body

THC from the marijuana acts on specific receptors in the brain, called cannabinoid receptors, starting off a chain of cellular reactions that finally lead to the euphoria, or "high" that users experience Certain areas in the brain, such as the hippocampus, the cerebellum, the basal ganglia and the cerebral cortex, have a higher concentration of cannabinoid receptors

These areas influence memory, concentration, pleasure, coordination and, sensory and time perception. 1 Therefore these functions are most adversely affected by marijuana use. Marijuana is usually smoked as a cigarette (called a joint or a nail) or in a pipe or bong

In recent years, it has appeared in blunts, which are cigars that have been emptied of tobacco and refilled with marijuana, often in combination with another drug, such as crack. The “blunts” retain tobacco leaf used to wrap the cigar and therefore it combines marijuana's active ingredients with nicotine and other harmful chemicals. Some users also mix marijuana into food or use it to brew tea.
