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, 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 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. Industrial hemp products are made from cannabis plants selected to produce an abundance of fibre.

Cannabis also has a long history of being used for medicinal purposes, and as a recreational drug known as marijuana or weed. 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...)

Coffeeshops are establishments in the Netherlands where the sale of cannabis for personal consumption by the public is tolerated by the local authorities (in Dutch called gedoogbeleid). Under the drug policy of the Netherlands, the sale of cannabis products in small quantities is allowed by 'licensed' coffee shops. The majority of these "coffeeshops" (in Dutch written as one word) also serve drinks and food. Coffeeshops are not allowed to serve alcohol or other drugs, and risk closure if they are found to be selling soft drugs to minors, hard drugs or selling alcohol. The idea of coffeeshops was introduced in the 1970s for the explicit purpose of keeping hard and soft drugs separated.
