Ecstasy is a class A controlled drug often consumed by the young population for recreational purposes. Documented complications of its use include hyperpyrexia, disseminated intravascular coagulation (DIC), renal failure and rhabdomyolysis. We report on two patients who developed pneumomediastinum after Ecstasy abuse. Both patients obtained and consumed the drug at the same establishment and presented to the same hospital within half an hour. The possible pathogenesis of this complication are discussed and the literature reviewed. Pneumomediastinum should be recognized as a possible complication of Ecstasy use. Conservative management is appropriate.
