Annual cannabis use by country

This is a list of countries (and some territories) by the annual prevalence of cannabis use as a percentage of the population aged 15-64 (unless otherwise indicated). The indicator is the "annual prevalence" rate which is the percentage of the youth and adult population who have consumed the drug at least once in the past survey year.

The primary source of information is the World Drug Report 2006 (WDR 2006), published by the United Nations Office on Drugs and Crime (UNODC). See also: Adult lifetime cannabis use by country.
