Uruguay legalized marijuana in 2013. Canada legalized it last week. In doing so, both countries put themselves in violation of the UN anti-drug treaties that are the legal backbone of global drug prohibition.
Not much happened. That’s because those treaties are toothless; they have no effective enforcement mechanisms. The global anti-drug bureaucrats at the Commission on Narcotic Drugs and the International Narcotics Control Board can write irate memos criticizing Ottawa and Montevideo, but that’s about it. They have done so, and Canada and Uruguay blithely ignored them.
