'''Drug testing''' is used to determine whether a person has consumed various psychoactive substances. It is used by the [[sports]] industry and is often used by [[employer]]s. It is also widely used in the criminal justice system, and in the federal system, is mandatory for federal probationers, where failed drug tests are one of the leading causes of probation violations. Failed urine screens are sometimes verified through more expensive procedures such as [[mass spectroscopy]] and [[gas chromatography]]. Another expensive drug testing method is hair testing.
