Cocaine
Cocaine (also cocain) is a strong stimulant drug that is made from coca leaves. Cocaine is usually a white powder. Most cocaine is used as an illegal drug. Because it is a stimulant, cocaine gives people energy. It also makes people feel very happy when it is taken. When used this way, cocaine is very addictive. However, cocaine can also be used as a local anesthetic if it is applied topically (onto the skin or gums).
