About drugs, it also depends on the kind of drug. For example, I don't know about marijuana, as far as I know there haven't been any deadly overdoses, but legalizing such a deadly thing as heroin imho is like legalizing murder for hire. I mean, you are right that it seems impossible to remove drugs from the streets; but for that matter it's impossible to eliminate crime as an existing phenomenon either, but that doesn't mean we don't have to fight it.
About alcohol prohibition, I think it also depends on the historical period. There is no prohibition today, but people don't drink as much as before and during the 20s.
