Hemp is the common name for plants of the entire genus Cannabis, although the term is often used to refer only to Cannabis strains cultivated for industrial (non-drug) use. Industrial hemp has many uses, including paper, textiles, biodegradable plastics, construction, health food, and fuel. It is one of the fastest growing biomasses known, and one of the earliest domesticated plants known. Here are 15 fascinating facts about the less-pleasurable version of weed.
