Drug injection is a method of introducing a drug into the body with a hollow 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. 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, methamphetamine).
