'''Marijuana''' (colloquially known as '''"weed"''' or '''"pot"''') is the name given to the flowering buds of the cannabis sativa plant prepared for human consumption. The main active ingredient in marijuana is [[Tetrahydrocannabinol|THC]], or delta-9-tetrahydrocannabinol, an [[organic chemistry|organic chemical]] compound. Marijuana is illegal to possess, cultivate and sell in most civilized areas of the world. However, there is a significant minority of countries and provinces in which possession is decriminalised, such as Portugal and Denmark. There are also countries, most famously the Netherlands, in which the sale of marijuana in small quantities is tolerated by law enforcement.

Marijuana is generally illegal to possess, cultivate and sell in most countries, although it is legal in some jurisdictions as a medical treatment. However, there is a significant minority of countries and provinces in which possession (usually of a small amount for personal use) is decriminalized; for instance Portugal, Argentina, California and South Australia. There are also countries, most famously the Netherlands, in which the sale of marijuana in small quantities is tolerated by law enforcement.

The effects of marijuana can include short-term memory loss, malaise, psychosis in predisposed individuals as well as impairment of physical and mental functioning. Some advocates of marijuana have claimed that it has medicinal benefits (see [[Medical marijuana]]), however many contest this, and state that there are numerous federally approved medicines for the diseases that medicinal marijuana can be used to treat.
