Cannabis (/ˈkænəbɪs/) is a genus of flowering plant that includes three species (and seven taxa) or subspecies, sativa, indica, and ruderalis. The plant is indigenous to central Asia and the Indian subcontinent.

Cannabis has long been used for hemp fibre, for hemp oils, for 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. Many plants have been selectively bred to produce a maximum of THC (cannabinoids), which is obtained by curing the flowers. Various compounds, including hashish and hash oil, are extracted from the plant. Globally, in 2013, 60,400 kilograms of cannabis were produced legally. In 2013 between 128 and 232 million people are thought to have used cannabis as a recreational drug (2.7% to 4.9% of the global population between the ages of 15 and 65).

Mary Jane Rathbun(December 22, 1922 – April 10, 1999), popularly known as Brownie Mary, was an American medical cannabis activist. As a hospital volunteer at San Francisco General Hospital, she became known for illegally 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).
