title: Two ways of estimating the euro value of the illicit market for cannabis in France.
abstract: BACKGROUND
  The most recent health surveys in general population are used in order to estimate the annual market size for cannabis in France in 2005.
  
  
  METHODS
  Two methods for arriving at an estimate are proposed: the first based on reported consumption, the other on reported expenditure on cannabis.
  
  
  RESULTS
  The annual sales figure for cannabis in France is between 746 and 832 million euro. Men's expenditure accounts for between 80 and 85% of total expenditure and those aged between 15 and 24 years account for the greatest part of the size of the cannabis market, between 57 and 60%, depending upon the method.
  
  
  CONCLUSIONS
  According to these estimates, consumers' average annual expenditure on cannabis is around euro 202 in France, compared to estimates obtained for New Zealand and Holland (euro 124) and the United States (euro 362).
