Hemp, or industrial hemp, is a phenotype of the Cannabis sativa plant species that is defined by the THC content. Hemp is grown for industrial uses of its derived products, as well as for various phytochemicals other than THC.[1] It is one of the fastest growing plants[2]and was one of the first plants to be spun into usable fiber 10,000 years ago.[3] It can be refined into a variety of commercial items, including paper, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.[4][5]
