Marijuana Toxicity

The term "marijuana" typically refers to the tobacco-like preparations of the leaves and flowers of the plant cannabis sativa and cannabis indica. The plant contains many psychoactive compounds, often referred to as cannabinoids. The primary psychoactive ingredient is believed to be tetrahydrocannabinol, which is also responsible for most of the intoxicating effects experienced by users. Different preparations of marijuana vary in strength, with THC concentration in cannabis varying with climate, soil, and cultivation techniques. Also, the amount absorbed by the body varies with the route of administration. The effects of cannabis depend on various things: the dose, mode of administration, user's prior experience with the drug, user's expectations/attitudes towards the drugs, and social environment when using the drug.
