What about meth, fentanyl or oxycotin? (to name just a few)
I would consider these more literal poison by comparison to alcohol by any objective manner. If they are all legal, then access/addiction/intoxication are not even close to compare to alcohol, they are all far worse.
They're not poison though based on they way they work with neuroreceptors whereas alcohol limits neurotransmission all together. None of them are good, and in excess they're both terrible.
