Cannabis sativa L. Cannabis indica Lam. (putative) Cannabis ruderalis Janisch. (putative)
Cannabis (Cán-na-bis) is a genus of flowering plants that includes three putative species, Cannabis sativa L., Cannabis indica Lam., and Cannabis ruderalis Janisch. These three taxa are indigenous to Central Asia, South Asia, and surrounding regions. Cannabis has long been used for fibre (hemp), for medicinal purposes, and as a recreational drug. Industrial hemp products are made from Cannabis plants selected to produce an abundance of fiber and minimal levels of THC (Δ9- tetrahydrocannabinol), a psychoactive molecule that produces the "high" associated with marijuana. The psychoactive product consists of dried flowers and leaves of plants selected to produce high levels of THC. Various extracts including hashish and hash oil are also produced from the plant.
