Tests for drugs of abuse in the urine provide a valuable method for keeping track of and identifying drug usage. Urine drug tests are frequently used in the criminal justice system (such as in problem-solving courts and correctional facilities) as part of a court-ordered treatment program, for workplace testing by employers to check for illicit drug use that could endanger employees or affect productivity, and by pain management clinics to make sure patients follow drug prescriptions and to watch for non-prescribed drug use that could affect health and treatment programs.

A drug is digested and broken down into metabolites after consumption, which is eliminated by various biological processes, including urine production. The presence of the parent drug and its metabolites in the person’s urine reveals if the subject has used drugs, when, and whether the abuse is chronic.
