You have absolutely no idea what you're talking about. You have no clue about the pharmaceutrical aspects of this discussion, about the effects of various drugs (even the legal ones) or about society as a whole apparently. The hugely massive minority of drug users are homeless, and your comment about 1 pill being able to kill you shows that you're lumping all drugs into one category and still somehow believing that alcohol "doesn't count". As for that, here's a handy chart of how dangerous various drugs are:
it's from 2006 so it may not be entirely up to date with certain street purity changes and a couple of classifications have changed, but chemicals themselves don't suddenly change their effects on the human brain and body so you can take it as being almost totally accurate still I'm sure. The fact that you base alcohol being safe on it being legal is just laughable
