Cocaine

Tropane alkaloid and stimulant drug

Cocaine is a tropane alkaloid that acts as a central nervous system (CNS) stimulant. As an extract, it is mainly used recreationally and often illegally for its euphoric and rewarding effects. It is also used in medicine by Indigenous South Americans for various purposes and rarely, but more formally, as a local anaesthetic or diagnostic tool by medical practitioners in more developed countries. It is primarily obtained from the leaves of two Coca species native to South America: Erythroxylum coca and E. novogranatense. After extraction from the plant, and further processing into cocaine hydrochloride, the drug is administered by being either snorted, applied topically to the mouth, or dissolved and injected into a vein. It can also then be turned into free base form, in which it can be heated until sublimated and then the vapours can be inhaled.
