What is Cannabis?
Cannabis (also known in its herbal form as marijuana or ganja, or as hashish in its resinous form) is the source of a psychoactive drug produced from parts of the Cannabis sativa plant. The herbal forms are primarily from the cured flowers and gathered trichomes of the female plant, as well as the less psychoactive remains of the plant; highly psychoactively concentrated resin, known as hashish, is composed of the compressed trichomes collected from the leaves and flowers of a mature, flowering female Cannabis plant.
The major active chemical compound Δ9-tetrahydrocannabinol, commonly referred to as THC, has psychoactive and medicinal effects when consumed, usually by smoking or ingestion. Humans have been consuming cannabis since prehistory, though in the 20th century there was a rise in the use of cannabis for recreational and religious purposes. At the beginning of the 21st century, it is estimated that cannabis is used regularly by four percent of the world's adult population each year,[1]with in the West estimates of up to 20% or greater in the United States as having tried the plant, and estimates of 10-30% or greater using the plant in many European countries. The possession, use, or sale of psychoactive cannabis products became illegal in most parts of the world in the early 20th century. Since then, while some countries have intensified the enforcement of cannabis prohibition, others have reduced the priority of enforcement almost to the point of legalization, as is the case in The Netherlands. The supplying of cannabis remains illegal almost everywhere in the world through the 1961 Single Convention on Narcotic Drugs, the 1971 Convention on Psychotropic Substances, and the 1988 United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, while simple possession of small quantities is either legal or treated as an addiction rather than a criminal offence in a few countries. Yet in some areas of India, near the Ganges river, it is traditionally and legally used.
