Cocaine - Simple English Wikipedia

# Cocaine

### From Wikipedia, a free encyclopedia written in simple English for easy reading.

Cocaine is a type of drug and is not allowed in many countries. Cocaine comes from the leaves of a plant called coca. It makes you feel high (happy feelings).

Cocaine is both a local anaesthetic, and a stimulant. Its anaesthetic properties are caused by the narrowing of blood vessels which makes it harder for the heart to pump blood. This causes the heart rate to increase. The euphoric stimulant properties are activated by a neurotransmitter in the brain called Dopamine, the same neurotransmitter affected by amphetamine.
