Cannabis (/ˈkænəbɪs/) is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: Cannabis sativa, C. indica, and C. ruderalis. Alternatively, C. ruderalis may be included within C. sativa, or all three may be treated as subspecies of C. sativa, or C. sativa may be accepted as a single undivided species. The genus is widely accepted as being indigenous to and originating from Asia.
The plant is also known as hemp, although this term is often used to refer only to varieties of Cannabiscultivated for non-drug use. Cannabis has long been used for hemp fibre, hemp seeds and their oils, hemp leaves for use as vegetables and as juice. Industrial hemp products are made from cannabis plants selected to produce an abundance of fibre.
Weekly cannabis use is generally required for the syndrome to occur; synthetic cannabinoids can also cause CHS. The underlying mechanism is unclear, with several possibilities proposed. Diagnosis is based on the symptoms, as well as the history of cannabis use (including a urine screen test if necessary). The condition is typically present for some time before the diagnosis is made.

The use of cannabis and other drugs came under increasing scrutiny after the formation of the Federal Bureau of Narcotics (FBN) in 1930, headed by Harry J. Anslinger as part of the government's broader push to outlaw all recreational drugs. Anslinger claimed cannabis caused people to commit violent crimes and act irrationally and overly sexual. The FBN produced propaganda films promoting Anslinger's views and Anslinger often commented to the press regarding his views on marijuana.

The illegality of cannabis is outrageous, an impediment to full utilization of a drug which helps produce the serenity and insight, sensitivity and fellowship so desperately needed in this increasingly mad and dangerous world.
