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, 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.
Medical cannabis, or medical marijuana (MMJ), is cannabis and cannabinoids that are prescribed by physicians for their patients. The use of cannabis as medicine has not been rigorously tested due to production and governmental restrictions, resulting in limited clinical research to define the safety and efficacy of using cannabis to treat diseases.
Preliminary evidence has indicated that cannabis might reduce nausea and vomiting during chemotherapy and reduce chronic pain and muscle spasms. Regarding non-inhaled cannabis or cannabinoids, a 2021 review found that it provided little relief against chronic pain and sleep disturbance, and caused several transient adverse effects, such as cognitive impairment, nausea, and drowsiness.

Reefer Madness (originally made as Tell Your Children), a 1936-1939 American propagandaexploitation film revolving around the melodramatic events that ensue when high school students are lured by pushers to try marijuana — from a hit and run accident, to manslaughter, suicide, attempted rape, and descent into madness. Originally financed by a church group under the title Tell Your Children, the film was intended to be shown to parents as a morality tale attempting to teach them about the dangers of cannabis use. However, it was purchased by producer Dwain Esper, who re-cut the film for distribution on the exploitation film circuit through the 40s and 50s. Although finding a popular audience as a cult film, critics have panned it as one of the worst films ever made.
