What is Crack: Definition and 56 Discussions

Crack cocaine, also known simply as crack or rock, is a free base form of cocaine that can be smoked. Crack offers a short, intense high to smokers. The Manual of Adolescent Substance Abuse Treatment calls it the most addictive form of cocaine. Crack first saw widespread use as a recreational drug in primarily impoverished neighborhoods in New York City, Philadelphia, Baltimore, Washington, D.C., Los Angeles, San Francisco, and Miami in late 1984 and 1985; its rapid increase in use and availability is sometimes termed as the "crack epidemic".
