Hemp (from Old English hænep) is a commonly used term for high growing varieties of the Cannabis plant and its products, which include fiber, oil, and seed. Hemp is refined into products such as hemp seed foods, hemp oil, wax, resin, rope, cloth, pulp, paper, and fuel.

Other variants of the herb Cannabis sativa are widely used as a drug, commonly known as marijuana. These variants are typically low growing and have higher content of tetrahydrocannabinol (THC).
