A briefing note prepared for then-foreign minister Stéphane Dion last year makes references to Uruguay, which legalized recreational pot in 2013 without leaving the treaties. While the UN’s International Narcotics Control Board disapproved, nothing much else happened, the note says:
“While the INCB remains steadfast in its assessment that Uruguay’s marijuana regime is inconsistent with the 1981 Single Convention on Narcotic Drugs, the Board has never raised the possibility of applying punitive measures against Uruguay over the issue.”
