Cocaine is a tropane alkaloid and stimulant drug obtained primarily from the leaves of two Coca species native to South America, Erythroxylum coca and Erythroxylum novogranatense. It is most commonly used as a recreational drug and euphoriant. After extraction from coca leaves and further processing into cocaine hydrochloride, the drug may be snorted, heated until sublimated and then inhaled, or dissolved and injected into a vein. Mental effects may include an intense feeling of happiness, sexual arousal, loss of contact with reality, or agitation. Physical symptoms may include a fast heart rate, sweating, and dilated pupils. High doses can result in high blood pressure or high body temperature. Effects begin within seconds to minutes of use and last between five and ninety minutes.
