Anything consumed by a person is broken down by the body so that the nutrients in the substance can be used or so that any toxins in the substance can be safely eliminated from the body. As drugs flow through the bloodstream and are filtered through the liver and other organs, these addictive chemicals are broken down and some are eliminated through urine, feces or sweat. These remnants of drugs are referred to as metabolites. This is what drug tests are looking for: what metabolites are left in a person’s body after they consumed cocaine, heroin, marijuana, alcohol, OxyContin, etc.
