A number of other countries have implemented changes in law that significantly reduce the extent of criminalization of marijuana use. Only in Australia and the Netherlands have there been any changes on the criminalization of the supply side and in neither of those countries is it legal to both produce and sell the drug. The relaxations so far, with the exception of the Netherlands, have not been very great i.e. have not much changed the legal risks faced by a user of marijuana. Thus it is perhaps not surprising that the changes in prevalence of use have not been substantial. This paper provides a brief review of the changes that have been tried outside the US. The emphasis is on the nature of the changes and how they have been implemented rather than on outcomes.
Cannabis was condemned by the 1961 Single Convention on Narcotic Drugs as a psychoactive drug with “particularly dangerous properties” and hardly any therapeutic value. Ever since, an increasing number of countries have shown discomfort with the treaty regime’s strictures through soft defections, stretching its legal flexibility to sometimes questionable limits.
Cannabis is the world’s most widely used illicit drug. But for how much longer? In a short space of time we have moved from absolute global prohibition of the drug, with the emergence of legalised and regulated production and retail not in just one nation (Uruguay) but also, surprisingly, in two US states (Colorado and Washington). Do these and other new permissive models in Spain and Belgium, for example, point to a tipping point in the debate? Could cannabis step out of the shadows and join the ranks of alcohol and tobacco, the world’s most popular legal and regulated drugs?
