On January 11th, 2013, Bolivia rejoined the Single Convention on Narcotic Drugs, with a reservation to the articles that oblige the signing parties to abolish the traditional consumption of the coca leaf. Despite the opposition of the the International Narcotics Control Board and 15, especially Western countries, the United Nations had to accept the return of Bolivia under the new conditions.

Twenty years ago it would have been unthinkable that the UN would adopt anything against the will of the collective formed by the U.S.A, Canada, the UK, Germany, Russia, France, Italy and Japan. But the days when the North could buy the votes of African and South American countries have gone.
