"Cocaine comes from the coca plant and is known by names such as 'crack,' 'coke,' and 'blow.' It is most commonly snorted in the form of a powder, but is also sometimes rubbed on the gums, smoked, or injected. The short-term effects of cocaine include increased alertness, body temperature, heart rate, and talkativeness. They may also advance to twitching, tremors, irritability, panic, seizure, stroke, heart attack, coma, and death."
