In the 20th century, the use of cannabis Sativa for medicinal purposes declined due to the passage of laws prohibiting its use. However, in recent years, there has been a resurgence.

The number of species within the Cannabis genus is a matter of debate. Three species may be recognized: Cannabis sativa, Cannabis indica, and Cannabis Ruderalis; C. Ruderalis may be included within C. Sativa; all three may be treated as subspecies of a single species, C. Sativa; or C. Sativa may be accepted as a single undivided species. The genus is widely accepted as indigenous to and originating from Central Asia, with some researchers also including South Asia.

C. Sativa is the most widespread variety of cannabis. It is an annual herbaceous plant growing to 1–4 m (3 ft 3 in–13 ft) tall and up to 2 m (6 ft 7 in) wide. The leaves are palmately compound or digitated, with serrate leaflets. The first pair of leaves usually have a single leaflet, the number gradually increasing up to a maximum of about thirteen leaflets per leaf (usually seven or nine), depending on variety and growing conditions. At the top of a flowering plant, this number again diminishes to a single leaflet per leaf. The lower leaf pairs usually occur in an opposite leaf arrangement and the upper leaf pairs in an alternate arrangement on the main stem of a mature plant.

The leaves of the Cannabis sativa plant are believed to have originated in the Himalayan region. They are broad, toothed, and have a palate shape. The leaves of the Cannabis indica plant are smaller, more narrow, and have a more finger-like form. The leaves of the Cannabis Ruderalis plant are the smallest of the three and are more round than the leaves of the other two varieties.
