Introduction

Cannabis sativa
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, 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 being indigenous to and originating from Central Asia, with some researchers also including upper South Asia in its origin.

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 fiber. To satisfy the UN Narcotics Convention, some cannabis strains have been bred to produce minimal levels of tetrahydrocannabinol (THC), the principal psychoactive constituent. Some strains have been selectively bred to produce a maximum of THC (a cannabinoid), the strength of which is enhanced by curing the fruits. Various compounds, including hashish and hash oil, are extracted from the plant.

Globally, in 2013, 60,400 kilograms of cannabis were produced legally. In 2014 there were an estimated 182.5 million cannabis users (3.8% of the population aged 15–64). This percentage did not change significantly between 1998 and 2014.

Bob Marley in concert, 1980
Robert Nesta "Bob" Marley OM (6 February 1945 – 11 May 1981) was a Jamaican reggae singer-songwriter, musician, and guitarist who achieved international fame and acclaim. Starting out in 1963 with the group the Wailers, he forged a distinctive songwriting and vocal style that would later resonate with audiences worldwide. The Wailers would go on to release some of the earliest reggae records with producer Lee Scratch Perry. After the Wailers disbanded in 1974, Marley pursued a solo career which culminated in the release of the album Exodus in 1977 which established his worldwide reputation and became one of the world's best-selling artists of all time, with sales of more than 75 million albums and singles. He was a committed Rastafari who infused his music with a profound sense of spirituality. Marley has also evolved into a global symbol, which has been endlessly merchandised through a variety of mediums. In light of this, author Dave Thompson in his book Reggae and Caribbean Music, laments what he perceives to be the commercialized pacification of Marley's more militant edge.

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.
