The drug cannabis
commonly known as marijuana, is produced from parts of the cannabis plant, primarily the cured flowers and gathered trichomes of the female plant. The active chemical compounds have psychoactive and medicinal effects when consumed, usually by smoking or ingestion.
Cannabis has been consumed by humans for thousands of years; in the 20th century there was an upswing in the use of cannabis for recreational and religious purposes
The possession, use, or sale of psychoactive cannabis products became illegal in many parts of the world during the early 20th century, especially during the War on Drugs. It has remained so into the 21st century, although prohibitions have been relaxed in some jurisdictions (such as The Netherlands)
