Hair Testing
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.
Famous quotes containing the words hair and/or testing:
“Every modern male has, lying at the bottom of his psyche, a large, primitive being covered with hair down to his feet. Making contact with this Wild Man is the step the Eighties male or the Nineties male has yet to take. That bucketing-out process has yet to begin in our contemporary culture.”
—Robert Bly (b. 1926)
“Traditional scientific method has always been at the very best 20-20 hindsight. It’s good for seeing where you’ve been. It’s good for testing the truth of what you think you know, but it can’t tell you where you ought to go.”
—Robert M. Pirsig (b. 1928)
