Drug Abuse Among Elective Surgeries: an Observational Study.

Drug abusers and addicts form a challenge to the anesthetist because of the added potential risks involved in the administration of anesthesia to this subset of patients, including potential unforeseen drug-drug interactions. In this study, we aimed at screening all patients scheduled for elective orthopedic or general surgeries at the Cairo University Teaching Hospital during a set period of time for the most commonly abused drugs in Egypt.
