Yeah, no one gives smokers lung transplants. Don't understand why it's acceptable to divert a vital organ to a person who 1) put substantial effort into trashing their body for many years and 2) is highly likely to start drinking again post-op.
It is, I can get drunkish every evening for a month without any real gain in tolerance or diminishment in desirable effects, then I can stop for a while (or continue for a while more) without any real issue. Opiates don't do that for me, I'm always having to take multi-month breaks for tolerance and be totally paranoid about my usage to avoid w/d.
