ABSTRACT
The term “marijuana” refers to most parts of the plant Cannabis sativa L., whether growing or not: the seeds; the resin extracted from any part of the plant; and every compound, salt, derivative, or mixture, but it does not include the mature stalks, fiber produced from the stalks, or oil or cake prepared from the seeds (Farnsworth, 1969). Cannabis sativa L. is an annual plant that grows in all parts of the world, generally reaching a height of 16-18 ft. It is widely accepted that Cannabis sativa L. belongs to a family (Cannabaceae) that has only one genus (Cannabis) with only one species (sativa) (ElSohly and Slade, 2005).
