title: Marijuana and other illicit drug use and the risk of injury: A case-control study.
abstract: OBJECTIVE
  Assess the associations between marijuana or other illicit drug use and injury risk.
  
  
  METHODS
  Case-control study. Cases were emergency department patients with acute injury. Age-sex matched controls were interviewed by telephone.
  
  
  RESULTS
  Marijuana use in the past seven days was associated with decreased risk, and use of other illicit drugs was associated with increased risk. Controlling for confounding had little effect.
  
  
  CONCLUSIONS
  Marijuana use may be associated with a decreased risk of injury. Other illicit drug use was associated with increased risk.
