Hair analysis to detect drugs of abuse has been used by court systems in the United States, United Kingdom, Canada, and other countries worldwide. In the United States, hair testing has been accepted in court cases as forensic evidence following the Frye Rule, the Federal Rules of Evidence, and the Daubert Rule. As such, hair testing results are legally and scientifically recognized as admissible evidence. Most hair tests screen and confirm for the main drugs of abuse (Cocaine, Amphetamines, Methamphetamines,Opiates, PCP, and Marijuana).
Hair testing for alcohol markers is now recognised in both the UK and US judicial systems. There are guidelines for hair testing that have been published by the Society of Hair Testing that specify the markers to be tested for and the cutoff concentrations that need to be tested. There are only a few UKAS ISO17025 accredited laboratories in the UK including Tricho Tech based in Cardiff and Alpha Biolaboratories based in Warrington, UK. Drugs of abuse that can be detected include Cannabis, Cocaine, Amphetamines and drugs new to the UK such as Mephedrone.
