How Is Cocaine Used? The powdered form of cocaine is either inhaled through the nose (snorted), where it is absorbed through the nasal tissue, or dissolved in water and injected into the bloodstream. Crack is a form of cocaine that has been processed to make a rock crystal (also called “freebase cocaine”) that can be smoked. The crystal is heated to produce vapors that are absorbed into the blood-stream through the lungs. (The term “crack” refers to the crackling sound produced by the rock as it is heated.) The intensity and duration of cocaine’s pleasurable effects depend on the way it is administered. Injecting or smoking cocaine delivers the drug rapidly into the bloodstream and brain, producing a quicker and stronger but shorter-lasting high than snorting. The high from snorting cocaine may last 15 to 30 minutes; the high from smoking may last 5 to 10 minutes. In order to sustain their high, people who use cocaine often use the drug in a binge pattern—taking the drug repeatedly within a relatively short period of time, at increasingly higher doses. This practice can easily lead to addiction, a chronic relapsing disease caused by changes in the brain and characterized by uncontrollable drug-seeking no matter the consequences. drugabuse.gov/
