Crack is a form of cocaine that is smoked, rather than snorted or injected.
Crack cocaine is a highly addictive and powerful stimulant that is derived from powdered cocaine using a simple conversion process. Crack emerged as a drug of abuse in the mid-1980s.
Crack cocaine is the freebase, smoked form of cocaine. It’s popular with drug users seeking an inexpensive, rapid-acting and ultra-potent, euphoric high. The name “crack” comes from the sound produced from burning the drug’s rock-shaped chunks.
