Use of cannabis has been legal in the Netherlands for years. Britain simple does not enforce their drug laws where cannabis is concerned and yet I have never heard of the UN worrying about the how these nations laws would send the wrong message abroad about this dreadful drug.
I hope the UN isnt expecting the US to be the leader to world any more. After all Obama is a leader from behind kind of despot.
It has nothing to do with cannabis, and everything to do with challenging big government, IMO.
