Marijuana is the herbal form of cannabis, a plant used for its psychoactive effects as a recreational drug and as a medicine. Chemically, the major psychoactive compound in marijuana is delta-9-tetrahydrocannabinol. Typically, marijuana itself is smoked. Other derivatives of the cannabis plant are ingested in other ways.
In different nations, marijuana is either a legal form of medicine or an outlawed narcotic. The Netherlands has traditionally been one of the most drug-tolerant nations. After the drug was outlawed in the United States in 1937 - a fact which did not prevent a profitable underground market for it through the rest of the 20th century - certain states made marijuana legal in the early 21st century.
