Hemp Overview

Both industrial hemp and the drug known as Cannabis are produced from this species, Cannabis sativa. It originates from Central and Western Asia to China and is now grown across large areas of Europe, Asia, Africa and America. This plant is famous for containing psychoactive component tetrahydrocannabinol (THC), but there are distinct strains bred from this species that have unique biochemical compositions and uses. Hemp has lower concentrations of THC and higher concentrations of cannabidiol (CBD), which decreases or eliminates its psychoactive effects. It is an annual broadleaf plant with a taproot and is capable of very rapid growth under ideal growing conditions. Hemp is used to make a variety of commercial and industrial products including rope, clothes, food, paper, textiles, plastics, insulation and biofuel. Cannabis has both medical and recreational uses. This plant has legal restrictions, these vary across different countries. Current legislation prohibits the use of Cannabis outside one's private dwelling, and the buying and selling of Cannabis.
