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.
The main categories are:
- stimulants (e.g. cocaine)
- depressants (e.g. alcohol)
- opium-related painkillers (e.g. heroin)
- hallucinogens (e.g. LSD)
