crack

Crack cocaine, commonly known simply as crack, and also known as 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. A crack addict is known as a "crackhead".
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; this rapid increase in use and availability was named the "crack epidemic", which began to wane in the 1990s. The use of another highly addictive stimulant drug, crystal meth, ballooned between 1994 and 2004.
