The legal status of cannabis for personal use is one of the most controversial policy issues in the European Union. Although cannabis is a classified narcotic drug placed under control by the United Nations and by all EU Member States, the measures adopted to control it at national level vary considerably, as shown in the table, click here to access the information country by country.Read more...

Perspectives on drugs
Three United Nations Conventions provide the international legal framework on drug control, instructing countries to limit drug supply and use to medical and scientific purposes. Yet, debate continues on the decriminalisation, or even legalisation, of drugs, particularly cannabis. Models under development for the legal supply of cannabis are described in this analysis, as well as some of the questions they raise.
Part of the ‘Perspectives on drugs’ (PODs) series, launched alongside the annual European Drug Report, these designed-for-the-web interactive analyses aim to provide deeper insights into a selection of important issues.Read more...
Recent developments in cannabis regulation
Cannabis is the most widely produced and consumed illicit substance globally. A significant number of states have long engaged in soft defection from the UN drug control regime in relation to tolerant policies on the personal possession, cultivation and use of cannabis. Recently, there has been growing debate within political circles on the benefits of regulated cannabis markets. This has been driven by a number of factors including the continuing illegality of supply, the associated and often violent involvement of criminal elements and the use of finite criminal justice resources. In this section you will find an overview of our most recent blogs on the issue.Read more...
Revisiting data casts doubts on link between heavy cannabis use and declining IQNature
Monday, January 14, 2013
Cannabis rots your brain — or does it? Last year, a paper published in Proceedings of the National Academy of Sciences (PNAS) suggested that people who used cannabis heavily as teenagers saw their IQs fall by middle age. But a study published today — also in PNAS — says that factors unrelated to cannabis use are to blame for the effect. Nature explores the competing claims.

Forget the antiquated dogma and judge pot prohibition on its own merits. If you still believe that cannabis should be illegal, then you must logically support the criminalization of alcohol and tobacco, with vigorous prosecution and even imprisonment of producers and consumers. Does that sound ridiculous? Then you must conclude that the only rational approach to cannabis is to legalize, regulate and tax it.
A dispensary-based survey of substitution effect in Canadian medical cannabis patientsPhilippe Lucas, Amanda Reiman, Mitch Earleywine, Stephanie K. McGowan, Megan Oleson, Michael P. Coward & Brian ThomasAddiction Research & Theory

This article examines the subjective impact of medical cannabis on the use of both licit and illicit substances via self-report from 404 medical cannabis patients recruited from four dispensaries in British Columbia, Canada. The aim of this study is to examine a phenomenon called substitution effect, in which the use of one product or substance is influenced by the use or availability of another.

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.

History was made as the Oregon Secretary of State announced that the Oregon Cannabis Tax Act turned in enough valid signatures to qualify for the 2012 ballot. Oregon joins Washington and Colorado in voting for marijuana legalization this year, the first time in history three U.S. states will put the legalization question to voters. Here is a look at the three legalization measures to be put before the voters in the November 2012 election.

The aim of this paper is to assess the influence of coffee shop availability on the prevalence and intensity of cannabis use, as well as the effectiveness of the ‘separation of markets’ policy. A convenience sample of nightlife visitors and a sub-selection of previous year cannabis users were used for analyses on cannabis and hard drugs use. Logistic regression analyses showed that coffee shop proximity does not seem to be linked to prevalence of cannabis use or intensity of use. In addition, proximity of coffee shops does not seem to be linked directly to hard drugs use.

This study brings together available evidence to provide a comprehensive analysis of cannabis production and markets across the EU. It combines information from EMCDDA routine reporting — data on patterns of prevalence and use, seizures, police reports, drug-law offences, cannabis potency and retail market prices — with literature on cannabis markets to create an in-depth analysis of the issue in a European context.
