Well, this is comics. If they wanted to, they could end addiction altogether with one visit to a sufficiently powerful telepath, or create tech that rewires the body in a way that makes it impossible for a person to get drunk. At one point we were told that Wolverine's healing ability was so powerful that he couldn't get really intoxicated without consuming massive amounts of alcohol in a short window of time. You'd think even turning into Binary-lite would burn most of the toxins out of Carol's system, but it doesn't. Even Galactus has been shown getting drunk, which I think is beyond ridiculous. But... writers. What can you do?
