Hair analysis for abused drugs has been gaining increasing significance in forensic sciences.8 For these reasons, testing for drugs in hair provides unique and useful information in several fields of toxicology, from which the most prominent is the possibility of studying individual drug use histories by means of segmental analysis.7 Hair is a special matrix for the retrospective investigation of chronic drug abuse or poisoning in criminal cases and allows to demonstrate with sensitive methods even a single administration in low amount.8 Various reports emphasize the use of hair in finding out the causes of death.710 Ethyl glucuronide (EtG) is a minor and direct metabolite of ethanol.
