When I get teeth pulled, I always smoke the same day.( Its my medicine.... I need it!) I've never had a problem. Since John doesn't smoke, I guess shotgun hits are out, but as Storm Crow says, just don't suck too hard. Its the blood clot you are trying to protect.
I doubt you'll even want to smoke until the drugs they use to knock you out wear off. They make you feel so icky when they are wearing off!
Good luck to you rebgirl! Its not really something to look forward to, is it?!
