Uruguay's move to legalise the production and sale of marijuana breaks international law. Warning it would encourage addiction, says the world drugs body.
"Uruguay is breaking the international conventions on drug control with the cannabis legislation approved by its congress," said the International Narcotics Control Board, a UN body that oversees the implementation of international treaties on drugs.
AdvertisementINCB president Raymond Yans added he was "surprised" that Montevideo had "knowingly decided to break the universally agreed and internationally endorsed legal provisions of the treaty."
He accused the country's lawmakers of ignoring scientific evidence on the health risks of marijuana, and said claims the law would help reduce crime relied on "rather precarious and unsubstantiated assumptions."
The move "will not protect young people, but rather have the perverse effect of encouraging early experimentation, lowering the age of first use, and thus contributing to... earlier onset of addiction and other disorders," said Yans.
Uruguay's parliament voted on Tuesday to legalise marijuana, becoming the first nation in the world to oversee the production and sale of the drug.
"The war against drugs has failed," said Senator Roberto Conde as he presented the bill on behalf of the ruling leftist Broad Front, calling it an "unavoidable response" to that failure.
The law not only authorises the production, distribution and sale of cannabis, but also allows individuals to grow their own on a small scale, and creates consumer clubs -- all under state supervision and control.
The UN office on drugs and crime on Wednesday said it agreed with the INCB statement and implicitly criticised Uruguay's unilateral move in the global war on drugs.
"Just as illicit drugs are everyone's shared responsibility, there is a need for each country to work closely together and to jointly agree on the way forward for dealing with this global challenge," it said in a statement.
