If you actually read the treaties, while they do set firm limitations on the legal, "non-medical" or "non-scientific" sale of schedule drugs — limits that Uruguay, Colorado and Washington ignored when legalizing cannabis — they don’t otherwise obligate countries to penalize drug use. Even the 1988 convention, the harshest of the three, which instructs countries to criminalize use, still provides an out for states, allowing such laws only as they are "subject to its constitutional principles and the basic concepts of its legal system." This loophole has been used by the Dutch to argue legally for their coffee shops.

The director of the United Nations Office on Drugs and Crime, Yury Fedotov, said that state-level marijuana legalization initiatives in the U.S. are violations of longstanding international drug treaties. "I don't see how [state-level marijuana legalization] can be compatible with existing conventions," he said according to Reuters. Fedotov's remarks are coming less than a month after Assistant Secretary of State Brownfield outlined an official policy of "flexibility" in the U.S.'s interpretation of existing U.N. drug control conventions, which require countries to outlaw the sale and use of cannabis.

Moves by some U.S. states to legalize marijuana are not in line with international drugs conventions, the U.N. anti-narcotics chief said, adding he would discuss the issue in Washington next week. 

The UN's top narcotics official said on Wednesday that recent votes by US states to legalize marijuana have put America in deeper violation of the international conventions that guide drug policy around the world. Earlier this month, voters in Oregon, Alaska, and Washington DC legalized the recreational use and sale of marijuana. Similar ballot initiatives have already passed and taken effect in Colorado and Washington.

What would the world look like if governments - instead of crime syndicates - controlled drug markets and drug use was decriminalized?

Ahead of the High-Level Segment on the world drug problem to take place on 13th and 14th January 2014, the UNODC Executive Director, Yuri Fedotov, has released his "contributions" to the debate. This 19-page document is, in parts, refreshingly honest about the “unequal” progress that has been made since 2009 (with reductions in supply or demand for some drugs in some places being offset by increases elsewhere), the setbacks and new challenges, and the fact that “the overall magnitude of drug demand has not substantially changed at the global level”.

On March 13-14, 2014, UN member states will gather in Vienna, Austria, for a High Level Segment of the annual UN Commission on Narcotic Drugs (CND). The purpose of this meeting is to review the progress made, and the challenges encountered, since the 2009 Political Declaration and Plan of Action on the World Drug Problem. The main focus of the High Level Segment will be the negotiation of a Joint Ministerial Statement, which will set the scene for the 2016 UN General Assembly Special Session on Drugs (UNGASS), as well as recording member states’ views of progress.
