Abstract
Marijuana is the popular name of the plant Cannabis sativa, a weed that will grow wild in most climates. The Cannabis plant contains a chemical known as tetrahydrocannabinol, or THC, which produces the psychoactive effects experienced by users. The THC content of Cannabis varies in different parts of the plant. The greatest concentration is usually found in a sticky resin produced by the plant, known as hashish. Declining concentrations are typically found in the flowers and leaves, respectively. Little THC is found in the stem, roots, or seeds of the plant. The potency and resulting effect of the drug fluctuate, depending on the relative proportion of these plant parts in the marijuana mixture consumed by the user.1 The most common method of administration is by smoking either the dried flowers and leaves or various preparations of hashish. Marijuana is also occasionally taken orally, typically baked in sweets such as brownies or cookies.2
