Cocaine is a white powder that can be snorted up the nose. Some users inject it.

Cocaine is a powerful stimulant. The buzz creates a sense of well-being, making users feel alert and confident. The effects last roughly 30 minutes. Users are often left craving more. People may also take more to delay the comedown (tiredness and depression).

Cocaine can cause heart problems and chest pain. Heavy use of cocaine can cause convulsions. Large or frequent doses over a short period can leave users restless, confused and paranoid. Snorting cocaine may permanently damage the inside of the nose. Users may find their habit expensive and hard to control.

Users have died from overdose.
