Introduction

Common hemp

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.

The plant is also known as hemp, although this term is often used to refer only to varieties of Cannabis cultivated 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, medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fibre. Various cannabis strains have been bred, often selectively to produce high or low levels of tetrahydrocannabinol (THC), a cannabinoid and the plant's principal psychoactive constituent. Compounds such as hashish and hash oil are extracted from the plant. (Full article...)

Female Cannabis sativa, recreational/medicinal marijuana

Cannabis sativa is an annual herbaceous flowering plant. The species was first classified by Carl Linnaeus in 1753. The specific epithet sativa means 'cultivated'. Indigenous to Eastern Asia, the plant is now of cosmopolitan distribution due to widespread cultivation. It has been cultivated throughout recorded history and used as a source of industrial fiber, seed oil, food, and medicine. It is also used as a recreational drug and for religious and spiritual purposes. (Full article...)

Reefer Madness (originally made as Tell Your Children), a 1936-1939 American propaganda exploitation film revolving around the melodramatic events that ensue when high school students are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.
