Cocaine

Cocaine is usually sold on the street as a white cristalline powder. It is often sniffed or smoked, but may also be swallowed or injected.

Cocaine creates mental well-being and a boosted self confidence. It inhibits sleep and appetite. When used over a longer period of time, the addict becomes restless and and is over-excited. Excessive doses can sometimes cause death from heart failure.

The euphoric 'high' is gradually replaced by insomnia and paranoia - and eventually hallucinations and delusions. Chronic abuse commonly damages the nasal membranes and the structure separating the nostrils and the respiratory tract.
