Cannabis (drug)

Cannabis, also known as marijuana, weed, and Cannabis sativa (as well as other names) is a psychoactive drug from the "Cannabis" plant used for medical or recreational purposes. The main psychoactive part of cannabis is tetrahydrocannabinol (THC), one of the 483 known compounds in the plant, including at least 65 other cannabinoids, which are chemicals only found in Cannabis. Cannabis can be used by smoking, vaporizing, within food, or as an extract.
Cannabis is mostly used recreationally or as a medicinal drug, although like other psychoactive drugs it may also be used for spiritual purposes. In 2013, between 128 and 232 million people used cannabis (2.7% to 4.9% of the global population between the ages of 15 and 65). It is the most commonly used illegal drug in the world, though it is legal in some jurisdictions, with the highest use among adults () in Zambia, the United States, Canada, and Nigeria.
Marijuana plants are grouped into 3 categories: Sativa, Indica, and Hybrid. A hybrid is a combination of Sativa and Indica. These 3 categories are then divided and categorized more into different strains. Strains are minor differences in how you feel when you use Cannabis. Some of the most famous and well-known strains of marijuana are: Acapulco Gold, Gelato, Grape Ape, White Widow, Purple Haze, Skunk and G13.
