What is crack?
Crack is the street name for a type of cocaine that has had the hydrochloride removed, making it possible to smoke.
When the mixture is heated, it makes a crackling sound, hence the name. Crack producers make crack with baking soda (sodium bicarbonate) or ammonia and water, and it is heated to remove the hydrochloride.
The crack smoker receives large doses of cocaine. The effect is intense and virtually immediate, as with injected cocaine, but the “high” lasts only around 5 minutes.
