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 are widely used as a drug, commonly known as marijuana. These variants are typically low-growing and have higher content of tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids. The legality of Cannabis varies widely from country to country, and from state to state in the United States. In many countries regulatory limits for concentrations of psychoactive drug compounds, particularly THC, in hemp require the use of strains of the plant which are bred for low content.[1]
