Uruguay has become first country in world to legalise marijuana trade, from drug’s production to its distribution. This means it is only nation where government has total control of commercialisation of marijuana (also known as cannabis). Uruguay's President Jose Mujica said his goal is to try and disrupt activities of drug traffickers and possibly put them out of business altogether. He hopes that his legalisation, together with close monitoring of marijuana sales by state, will reduce dependence on drug and drug-related crime. Mr Mujica said he was well aware that new legislation was " experiment," which had no guarantee of being successful. legalisation has fallen foul of international treaty on drug control. Uruguay is signatory to the 1961 Convention on Narcotic Drugs. The Convention limits use of cannabis "to medical and scientific purposes". president of International Narcotics Control Board, Raymond Yans, said he was "surprised" that Uruguay had "knowingly decided to break universally agreed and internationally endorsed legal provisions of treaty". He warned the move could backfire, saying: "It will not protect young people, but rather have perverse effect of encouraging early experimentation, lowering the age of first use, and thus contributing to…earlier onset of addiction and other disorders."
