Cocaine is a stimulant drug, which means that it speeds up the messages travelling between the brain and the rest of the body.
Cocaine comes from the leaves of the coca bush (Erythroxylum coca), which is native to South America. The leaf extract is processed to produce 3 different forms of cocaine:
C, coke, nose candy, snow, white lady, toot, Charlie, blow, white dust or stardust.
