==Description==
'''Cannabis''' (/ˈkænəbɪs/) is a genus of flowering plant that includes three [[species]] (and seven taxa) or subspecies, [https://en.wikipedia.org/wiki/Cannabis_sativa sativa], [https://en.wikipedia.org/wiki/Cannabis_indica indica], and [https://en.wikipedia.org/wiki/Cannabis_ruderalis ruderalis]. The plant is indigenous to central Asia and the Indian subcontinent.
''Cannabis'' has long been used for [[hemp]] fibre, for hemp oils, for [[medicinal]] purposes, and as a recreational [[drug]]. Industrial hemp products are made from cannabis plants selected to produce an [[abundance]] of fiber. To satisfy the UN Narcotics Convention, some cannabis strains have been bred to produce minimal levels of [https://en.wikipedia.org/wiki/Tetrahydrocannabinol tetrahydrocannabinol] (THC), the principal psychoactive constituent. Many plants have been selectively bred to produce a maximum of THC (cannabinoids), which is obtained by curing the flowers. Various compounds, including [https://en.wikipedia.org/wiki/Hashish hashish] and hash oil, are extracted from the plant.
Globally, in 2013, 60,400 kilograms of cannabis were produced legally. In 2014 there were an estimated 182.5 million cannabis users (3.8% of the population aged 15-64).[7] This percentage has not changed significantly between 1998 and 2014.
''Cannabis sativa'' appears naturally in many tropical and humid parts of the world. Its use as a [[mind]]-altering drug has been documented by [[archaeological]] finds in prehistoric societies in Euro-Asia and Africa.
The oldest written record of cannabis usage is the Greek historian [https://en.wikipedia.org/wiki/Herodotus Herodotus]'s reference to the central Eurasian [https://en.wikipedia.org/wiki/Scythians Scythians] taking cannabis steam baths. His (c. 440 BCE) ''[https://en.wikipedia.org/wiki/Histories_(Herodotus) Histories]'' records,
<blockquote>"The Scythians, as I said, take some of this hemp-seed [presumably, flowers], and, creeping under the felt coverings, throw it upon the red-hot stones; immediately it smokes, and gives out such a vapour as no Grecian vapour-bath can exceed; the Scyths, delighted, shout for joy."</blockquote>
Classical Greeks and Romans were using cannabis, while in the [[Middle East]], use spread throughout the Islamic empire to North Africa. In 1545 cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. In North America cannabis, in the form of hemp, was grown for use in rope, clothing and paper.
