Hair drug testing is a method that can detect drug use over a much longer period of time than saliva, sweat or urine tests. Hair testing is also more robust with respect to tampering. 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.
Hair grows at approximately the rate of ½ an inch per month and takes about 5 days to grow out past the external layer of skin. Psychemedics’ standard test uses a 1 ½ inch sample of head hair, which provides an approximate 3 month history of drug use. Body hair can also be collected if head hair is not available. [2]
Chemical hair analysis may be considered for retrospective purposes when blood and urine are no longer expected to contain a particular contaminant, typically three months or less. Its most widely accepted use is in the fields of forensic toxicology, in pre-employment drug testing and, increasingly, in environmental toxicology.
Cannabis use is detectable with hair tests and is generally included in the standard hair test. Hair tests generally take the most recent 1.5 inches of growth and use those for testing. That provides a detection period of approximately 90 days. [5] If an individual's hair is shorter than 1.5 inches, this detection period will be shorter.
