Cannabis plants produce a group of chemicals called cannabinoids, which generate mental and physical effects when consumed.

Cannabinoids, terpenoids, and other compounds are secreted by glandular trichomes that occur most abundantly on the floral calyxes and bracts of female plants.
As a drug it usually comes in the form of dried infructescences ("buds" or "marijuana"), resin (hashish), or various extracts collectively known as hashish oil.
During the 20th century, it became illegal in most of the world to cultivate or possess Cannabis for sale, and even sometimes for personal use.
