How do people use cocaine?
People snort cocaine powder through the nose, or they rub it into their gums. Others dissolve the powder and inject it into the bloodstream. Some people inject a combination of cocaine and heroin, called a Speedball.

Another popular method of use is to smoke cocaine that has been processed to make a rock crystal (also called “freebase cocaine”). The crystal is heated to produce vapors that are inhaled into the lungs. This form of cocaine is called Crack, which refers to the crackling sound of the rock as it’s heated. Some people also smoke Crack by sprinkling it on marijuana or tobacco, and smoke it like a cigarette.
