Maybe the UK and US are the worst offenders. Australia and New Zealand are very much more open, I suppose Canada is too. Outside of the west, I think that for instance China will listen. They've been involving foreign groups in their drug rehabilitation process reform for some years now.
The annoying thing is that other governments are pressured by the USA to keep criminalizing drugs, while the USA itself is decriminalizing it state by state.
The states are in direct contravention of Federal laws. This will have to be dealt with eventually but the Feds are in no hurry because it is a losing case for them.
Be very interesting to see what Congress ends up doing with DC, which recently decriminalized marijuana and has full legalization on the ballot for November. I don't think they'll ignore it, so the question is will they simply undo it or prevent the ballots from being counted (which they have the unique ability to do in DC) or whether this will prompt an actual debate on the role of the federal government in drug policy.
