Thus, hair sampling is preferred by the US military [66] and by many large corporations, which are subject to Drug-Free Workplace Act of 1988.
Chemical hair analysis is used for the detection of many therapeutic drugs and recreational drugs, including cocaine, heroin, benzodiazepines and amphetamines. [3] [4] Hair analysis is less invasive than a blood test, if not quite as universally applicable.
