A lot of times the no-smoking-after-surgery prohibition really refers more to no cigarette smoking, but it's true that any smoke might make the risk of dry sockets worse because of potential drying, which could set up the conditions for infection. A good length of time to wait would probably be five to seven days, but I know that's a bummer. Think about the alternative, though, of possibly getting an infection or having to go back in for a cleanout procedure, then having to delay smoking even longer.
