I agree that healing is greatly disrupted by smoking. Anesthesia is also affected by smoking. You're just going to have to call the doctor's office and tell him the facts of the number of cigarettes that your son is smoking/day. The doctor or his PA is the one that needs to call your son back and tell him why he is cancelling the surgery and for how long he is cancelling the surgery and what blood tests he will do in the future to make sure that he is no longer smoking. You shouldn't look like the one that cancelled the surgery, it is between your son and his doctor. Your son needs to take responsibility for the smoking that he his doing, and the quitting that he is going to do to re-schedule the surgery. He needs to get together a plan with the doctor/PA on how he is going to do it and be accountible for that plan. Your son needs to man-up here.
My heart goes out to you as his mom, but the surgery is tough as it is let alone having something like smoking decrease your son's healing. Also, the further that your son is from smoking when he has the surgery, the less likely it is that he will go back to smoking post-op.
