Abstract
While testing hair for drugs of abuse has become more widely used in the past 30 years, significant challenges still remain to the interpretation of the results from these tests. Of primary concern is the likelihood of unwitting contamination from the environment producing a result indicative of drug use. It is imperative that this possibility be controlled and understood so that results from hair testing can be appropriately interpreted.
