When I had that emergency appendectomy in June, all I told them was that I had been smoke-free for 110 days (at that time). They didn't ask anything else, and I was in far too much pain to volunteer anything. I had absolutely zero ill effects, got to go home about 2 hrs after the surgery. Healing progressed normally, except for the incision actually in my navel, where the surgeon actually removed the septic tissue -- she said the appendix was basically in tatters, it was so septic. I'm pretty sure that secondary infection was due more to not fully removing all the septic material, than to the fact that I was a vaper.

I think the face is where smoking really works against you. Not as much in other areas. Still, a boob job or tummy tuck or other procedures might not happen if you smoke. Reputable PS's don't want their work to look bad because someone uses nicotine.
Also, there is a chance of pneumonia from the anesthesia. Probably more so with smoking but I'm not sure about that.
