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 .

A presumptive test to detect saliva is the alpha-amylase test also known as the Phadebas Test. [4] This detection technique is based on the activity of the enzyme alpha-amylase which breaks down starches from food into smaller oligosaccharide molecules, starting digestion in the mouth. [ 11 ]
Most people who take a drug test take a presumptive test, cheaper and faster than other methods of testing. However, it is less accurate and can render false results.

[24] Per National Institute on Drug Abuse saliva drug testing provides a reasonable alternative to other drug ...
