TY - JOUR AB - Human hair may contain deposits of illicit drugs. Testing of hair will provide an indicator of drug use at the time the hair was grown. Hair samples have several advantages over urine samples, particularly length of surveillance period (months rather than days) and resistance to tampering. Any form of drug‐testing must be seen as a component of a clinical plan for the management of the patient's drug misuse, mental disorder and offending.
