Cocaine (benzoylmethyl ecgonine) is an alkaloid derived from the leaves of the coca plant. It is a white crystalline powder used as a local anaesthetic and also, illegally, as a euphoric drug. Cocaine taken recreationally is cut into a fine powder, arranged in what is termed a line, and inhaled through the nose - typically through a rolled-up banknote. A form of cocaine, known as crack, is smoked.
Cocaine provides the user with about thirty minutes of good-feeling, users report an increase in awareness, self confidence and sexual pleasure - the cocaine prevents the re-absorption of dopamine in the brain. Taking alcohol with cocaine enhances the effect of the cocaine. However, after about thirty minutes the effects wear off and the users may be left feeling depressed and paranoid. Inhaling cocaine often causes irritation to the sinuses, a condition known as a Columbian cold, and prolonged use can destroy the lining of the nose. Some sources claim that cocaine can cause cardiac arrest or strokes through increased blood pressure. Research Cocaine
