Ecstasy induced retropharyngeal emphysema.

Abstract

This is the first reported case of isolated retropharyngeal emphysema caused by ingestion of the amphetamine derivatives "Ecstasy" and "Speed". The same complication has been reported with marihuana, cocaine, and heroin abuse. The condition resolved spontaneously and this seems to be the experience of others who have reported cases of cervical emphysema and pneumomediastinum associated with substance abuse. Because of the self limiting nature of this condition, extensive investigations may not be necessary but hospital admission and close observation are still mandatory.
