title: [Acute respiratory problems and cocaine or heroine smoking].
abstract: BACKGROUND
  To explore if cocaine or heroin smoking was positively associated to acute respiratory complications (ARC).
  
  
  METHODS
  We collected data from medical records for 717 cocaine users who were attended in 14 hospital emergency rooms. The association was studied by logistic regression.
  
  
  RESULTS
  The most frequent ARC were respiratory infections and complications with chest pain or dyspnea. Cocaine smokers (OR = 3.3; CI 95% = 1.5-6.9) and cocaine sniffers (OR = 2.5; CI 95% = 1.1-5.6) had greater risk of ARC than cocaine injectors. Heroin smokers (OR = 3.5; COI 95% = 1.8-7.0) and heroin sniffers (OR = 2.8; CI 95% = 1.4-5.6) had greater risk of ARC than non heroin users.
  
  
  CONCLUSIONS
  These results suggest that cocaine or heroin smoking increases the risk of ARC.
