2-4 weeks: The nicotine metabolite is present in urine for up to 4 weeks depending on how much you smoke.

Something fishy...: It would be unusual to test a smoker. Don't they believe you when you say you smoke? Or did you not tell the truth? Best to fess up. Quitting smoking just before surgery is not a good idea.
