    This report brings together, for the first time in Europe, an integrated overview of the prevalence of intensive cannabis use, defined as daily or almost daily cannabis use (use on 20 or more days in the month preceding survey). Self-reported data regarding frequency of cannabis use from large, probabilistic, nationally representative samples of general population surveys from 20 countries, representing more than 83 % of the population of EU and Norway, were collected through two rounds of ad hoc data collection in 2004 and 2007 and through a routine, standard data collection instrument since 2010.

     

  2. Marijuana Legalization

    • Peter Reuter (RAND)

    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.
