Commonly abused drugs such as alcohol, cannabis, cocaine, and heroin are still the most widely used, but hundreds of new synthetic substances have emerged in recent years. The main danger is the lack of knowledge of what they really contain.
The word cocaine refers to a strong stimulant in a white powder or crystal form that is sold on the illicit market. In its crystal form, it is called crack cocaine. The powder is usually diluted with substances such as cornstarch, talcum powder, sugar or other drugs, such as procaine (a local anesthetic) or amphetamine. Many people know that cocaine was originally developed as a painkiller.
