I agree that things would be significantly different outside the US. There are too many "Republican, hard-core Christian, conservative muthas", as you put it, and they hate progressive change in society with every inch of their bodies. America will probably be one of the last countries to legalize it because of these strong reactionary forces in American society.

I think Europe will legalize it first. Drug policies in Belgium and Germany are already starting to be influenced by the success of their Dutch neighbors, and I think a wave of decriminalization/legalization throughout the EU is a real possibility in the coming years. The next candidate for legalization is Latin America. In Colombia and Peru it is already legal in small amounts for personal use. In large parts of Latin America the drug trade is deeply entwined with society at all levels, from the poorest peasants to the richest government officials, and the drug laws are really only there to prevent a US invasion.
