I agree that "legalize all drugs" is problematic, and probably not a good idea. "legalize all drugs less addictive than coffee" is a better option, that allows cannabis and mushrooms. (some people argue "all drugs less addictive than alcohol", but that would include cocaine). However, that still has the problem that customer won't know for sure what they're buying without some sort of FDA control, and small kids getting their hands on the stuff too easily. So as a third revision I propose "Regulate all drugs less addictive than coffee to be legally available to adults". Not very catchy.
