Cannabis, also known as marijuana or ganja (from Hindi: Ganja), is a psychoactive product of the plant Cannabis sativa. The herbal form of the
drug consists of dried mature flowers and subtending leaves of pistillate ("female") plants. The resinous form, known as hashish, consists
primarily of glandular trichomes collected from the same plant material.
A dried flowered bud of the Cannabis sativa plant.The major biologically active chemical compound in cannabis is ?9-tetrahydrocannabinol
(delta-9-tetrahydrocannabinol), commonly referred to as THC.
Humans have been consuming cannabis since prehistory, although in the 20th century there was a rise in its use for recreational,
religious or spiritual, and medicinal purposes. It is estimated that about four percent of the world's adult population use cannabis
annually and 0.6 percent daily. The possession, use, or sale of psychoactive cannabis products became illegal in most
parts of the world in the 20th century around the period when cigarettes became produced and marketed heavily internationally via the mass media.
Since then, some countries have intensified the enforcement of cannabis prohibition while others have reduced the priority of enforcement. The Netherlands
has been at the cutting edge of this move in their view of Marijuana as "soft drugs" (i.e. categorizing it like cigarettes, alcohol, etc.).
