Cocaine abuse is associated with a significant number of emergency medical services (EMS) calls and emergency department visits every year. The medical complications of recreational cocaine use are diverse, involving almost any body organ, and vary greatly according to the substance used and the route by which is taken. Previous reports have associated cocaine abuse with serious pulmonary complications, including barotrauma. The occurrence of barotrauma is directly related to the way cocaine is consumed. The majority may manifest clinically with subcutaneous emphysema, chest pain, and neck pain. We report a case of cocaine-induced pneumomediastinum in the prehospital environment that masqueraded as an allergic reaction. Prehospital providers should be alert for clinical manifestations suggestive of barotrauma in cocaine users.
