AV Superman can't drunk though right unless he had some Kryptonite on him and wasn't under a Yellow or Blue Star. Neurotoxins work for Supes. "In Superman: American Alien #3, Clark Kent is mistaken for Bruce Wayne by an assassin (Deathstroke). Deathstroke slips him a neurotoxin in a glass of champagne that would kill a human, but just makes Clark act for all the world like he's drunk. While this isn't intoxication by alcohol, it's amusingly close."
