Cocaine is responsible for excitement, and a feeling of strength and euphoria.

Hence a feeling of well-being, alertness and self-confidence is enhanced in the user. Euphoric effects last for about 15-30 minutes in a person. Cocaine is also an appetite suppressant decreasing hunger. The drug also affects peripheral nervous system.
