title: [Bronchial mucoepidermoid carcinoma in a 22 year-old cannabis smoker].
abstract: BACKGROUND
  Bronchial mucoepidermoid carcinoma represents less than 0.5% of malignant bronchopulmonary cancers. The factors of risk have not been clearly established. Consumption of cannabis could be incriminated, as is suggested by this case report.
  
  
  METHODS
  A 22 year-old man presented with a mucoepidermoid carcinoma of the middle bronchopulmonary lobe. This young man had consumed large quantities of tobacco and cannabis since the age of eleven.
  
  
  CONCLUSIONS
  The relationship between this rare tumour and the addictions in this patient merit further discussion. The oncogenic role of cannabis smoke should be envisaged, and emphasis placed on the possible synergic effects of multiple addiction, in this case tobacco and cannabis.
