There's "poisoning" from lots of stuff that we wouldn't traditionally classify as "poison", like water [1] or oxygen [2].
I am not a chemist or a doctor, but I think the common adage is "it's the dose that makes the poison". Most stuff is bad for you if you get too much of it.
What? Maybe I was unclear. I'm not saying it's not a poison. It seems like I walked into some entrenched debate and I don't even know what it is. Is it obvious that alcohol has sex specific effects? I didn't know. Is this some kind of culture war thing?
