Two ways of estimating the euro value of the illicit market for cannabis in France.

Introduction. 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 euros. 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).
