How Does Marijuana Work?
The main active chemical in marijuana is THC (delta-9-tetrahydrocannabinol), the psychoactive ingredient. The highest concentrations of THC are found in the dried flowers, or buds. 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. Feeling of a relaxed state, euphoria, and an enhanced sensory perception may occur. With higher THC levels in those who are not used to the effects, some people may feel anxious, paranoid, or have a panic attack.
How is Marijuana Used?
Marijuana may be smoked as a cigarette (called a joint or a nail) or in a pipe or bong. It may be smoked 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.
