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, 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...)

Mary Jane Rathbun (December 22, 1922 – April 10, 1999), popularly known as Brownie Mary, was an American medical cannabis rights activist. As a hospital volunteer at San Francisco General Hospital, she became known for baking and distributing cannabis brownies to AIDS patients. Along with activist Dennis Peron, Rathbun lobbied for the legalization of cannabis for medical use, and she helped pass San Francisco Proposition P (1991) and California Proposition 215 (1996) to achieve those goals. She also contributed to the establishment of the San Francisco Cannabis Buyers Club, the first medical cannabis dispensary in the United States.

Rathbun was arrested on three occasions, with each arrest bringing increased local, national, and international media attention to the medical cannabis movement. Her grandmotherly appearance generated public sympathy for her cause and undermined attempts by the district attorney's office to prosecute her for possession. The City of San Francisco eventually gave Rathbun permission to distribute cannabis brownies to people with AIDS. Her arrests generated interest in the medical community and motivated researchers to propose one of the first clinical trials to study the effects of cannabinoids in HIV-infected adults.

Joint is a slang term for a cigarette rolled using cannabis. Rolling papers are the most common rolling medium in industrialized countries; however, brown paper, cigarettes with the tobacco removed, beedis with the tobacco removed, tracing paper, ATM receipts and newspaper are commonly used in some developing countries, and by poorer smokers in first world countries. Modern papers are now made in a range of sizes from a wide variety of materials including rice, hemp, and flax, and are also available in flavored varieties. A joint can vary in size, typically containing between 0.25 to 1 grams net weight of cannabis (joints have been rolled with 2 or more pounds but this is not a common practice) (depending on whether tobacco is used in the rolling process).
