Drug injection is a method of introducing a drug into the bloodstream via a hollow hypodermic needle and a syringe, which is pierced through the skin into the body (usually intravenous, but also intramuscular or subcutaneous). It often applies to substance dependence and recreational drug use. Typically, the powdered drug is mixed with water to create a solution, and then the solution is injected. This act is often colloquially referred to as "slamming '', "shooting (up) '', "banging '', "pinning '', or "jacking - up '', often depending on the specific drug subculture in which the term is used (i.e. heroin, cocaine, or methamphetamine).
