Applications
Verification of history of drug use
By providing information on exposure to drugs over time, hair analysis may be useful in verifying self-reported histories of drug use in any situation in which a history of past rather than recent drug use is desired, as in pre-employment and employee drug testing. In addition, hair analysis may be especially useful when a history of drug use is difficult or impossible to obtain, such as from psychiatric patients. During control tests of hair fragments, a drug addict is not able to hide that drugs have been used, whereas intermittent drug use may be difficult to detect if urine or blood tests alone are undertaken, even when the tests are repeated.
