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