'''Cocaine''' is a potent [[central nervous system]] (CNS) [[stimulant]] and tropane alkaloid. Regular use of cocaine carries a high risk of [[addiction]]. Cocaine was first used natives of South America who chewed the leaves of the coca plant, and then later isolated and purified for medical use as a local anesthetic.
Cocaine is extracted from the leaves of the coca plant (Erythroxylum coca), which is indigenous to the Andean highlands of South America. Natives in this region chew or brew coca leaves into a tea for refreshment and to relieve fatigue, similar to the customs of chewing tobacco and drinking tea or coffee.
