Crack cocaine is a highly potent and addictive stimulant processed from powdered cocaine and made to look like a rock crystal. Crack produces effects similar to those of powdered cocaine but comes with a higher number of health risks, including lung trauma and bleeding.
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.
