Cocaine is a white powder that comes from the leaves of the South American coca plant.
Users call it by a variety of names, including coke, C, snow, blow, toot, nose candy, flake, and The Lady. Cocaine belongs to a class of drugs known as stimulants, which tend to give a temporary illusion of limitless power and energy that leaves the user feeling depressed, edgy, and craving more. Crack is a form of cocaine that has been chemically altered so that it can be smoked. Cocaine and crack are highly addictive. This addiction can erode physical and mental health and can become so strong that these drugs dominate all aspects of an addict's life.
