The International Narcotics Control Board is criticizing the decision by Colorado and Washington voters to regulate and control marijuana, saying that such a move violates international drug control agreements.
As the Guardian reported on March 5, 2013:
Launching its annual report in London, Raymond Yans, the INCB president, said that the successful ballots in Colorado and Washington to legalise the use of cannabis for recreational purposes and the fact that Massachusetts had recently become the 18th state to allow the use of cannabis for medicinal purposes violate the international drug conventions.
