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 tempering. 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.
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.

[3] [4] Hair analysis is less invasive than a blood test, if not quite as universally applicable. In this context, it has been reliably used to determine compliance with therapeutic drug ...
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]
Reagent testing is one of the processes used to identify substances contained within a pill, usually illicit substances. With the increased prevalence of drugs being available in their pure forms, the terms "drug checking" or "pill testing" [1] may also be used, although these terms usually refer to testing with a wider variety of techniques covered by drug checking.
A 2000 study by the US NIST [6] examined 12 chemical spot tests and concluded that all the tests examined "may indicate a specific drug or class of drugs is in the sample, but the tests are not always specific for a single drug or [class]". The study also noted that "mace, nutmeg and tea reacted with the modified Duquenois–Levine [test]".
