Cocaine is classified as a stimulant drug because it stimulates the central nervous system. Cocaine can be either be smoked (as crack), injected into the bloodstream, or snorted. The effects of cocaine are rapid and last for about 15-30 minutes. Cocaine is highly addictive and after each cocaine "rush" the user becomes depressed due to the decrease of the neurotransmitters serotonin, norepinephrine, and dopamine in the brain. If abused, a person can develop a tolerance to cocaine in which a user must abuse large amounts of cocaine to experience its effect.
