Cannabis, known as marijuana in its herbal form, is a psychoactive product of the plant Cannabis sativa. 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. It has psychoactive and physiological effects when consumed, usually by smoking or ingestion.
The minimum amount of THC required to have a perceptible psychoactive effect is about 10 micrograms per kilogram of body weight. The state of intoxication due to cannabis consumption is colloquially known as a “high”; it is the state where mental and physical facilities are noticeably altered due to the consumption of cannabis.
Each user experiences a different high, and the nature of it may vary upon factors such as potency, dose, chemical composition, method of consumption and set and setting.
