This report examines what is known about the effects of policies regarding the possession and use of cannabis. Such policies continue to be subject to debate in most if not all European countries. Different governments have made different policy decisions, varying from explicit toleration (but not full legalisation) to strict prohibition. Policymaking would be served by insight in the relationship between different cannabis policies and their outcomes, such as prevalence of cannabis use and social consequences for cannabis users and for society as a whole.
