[Acute eosinophilic pneumonia and illicit psychoactive substance use].

Illicit psychoactive substance (IPAS) use can lead to a number of respiratory complications, including acute eosinophilic pneumonia (AEP). Systematic literature review of data on AEP in IPAS users (cannabis, cocaine, heroin and amphetamine). Of two cases of cannabis and tobacco users reported to have developed AEP, one, a teenage15 year old boy presented with acute respiratory distress syndrome (ARSD) which necessitated extracorporeal membrane oxygenation (ECMO). Five cases of AEP in cocaine smokers (crack) are reported, one of which was fatal. The patient presented with acute pulmonary edema and ARDS which progressed to ventricular fibrillation and asystole. A 24-year-old woman presented with AEP after repeated inhalation of heroin. Finally, a case of an amphetamine abuser who developed AEP and ARDS after amphetamine inhalation is reported. The time between the first IPAS use and admission in cases reported ranged from 7 days to 4 years, while time between the last IPAS use and admission was short (less than 15 days). IPAS use must be sought in case of AEP, especially in young adults, and practitioners must advise and help users to stop their consumption.
