Are drugs and prostitution legal in some countries which are not total disasters?

Just curious, are there any countries where drugs (that are illegal on the U.S) and prostitution are 100% legal, and those same countries aren’t royally screwed up by the legality of those vices? If so, which countries are they, or do they even exist?
