Cocaine is a stimulant which is more commonly used as a recreational drug than for performance enhancement. Cocaine produces feelings of euphoria and wellbeing, which are usually followed by feelings of anxiety and depression when the effects of the drug wear off.

Repeated use usually results in tachyphylaxis (a decreasing response to the drug) which often causing the recreational user to deviate to more potent drugs.
