Cocaine is an addictive, illegal, stimulant drug made from the coco plant native to South America. As a street drug, cocaine is a fine, white crystal powder. Cocaine can also be processed to make a rock crystal, called crack. Cocaine increases the level of dopamine in brain circuits, and can cause hypersensitivity, irritability, paranoia, tremors or muscle twitches and a fast or irregular heartbeat, or in large amounts bizarre, unpredictable, and violent behavior.
