title: Occult benzodiazepine dependence.
abstract: Illicit street heroin is often adulterated with other substances, which may expose the unknowing user to additional adverse risks. This case study describes an intravenous heroin user with a history of epileptic seizures, who presented with unexpected benzodiazepine withdrawal symptoms. It highlights the importance of a thorough drug history with corroborative urine drug testing.
