It's difficult to say whether they will do a nicotine test on the day of surgery. If surgeons are concerned that their patients are smoking and not telling them, then they may do a nicotine test on the day of surgery. Regardless, if you have been smoking before your procedure I would postpone your surgery and make sure that you are able to fully comply with your surgeon's recommendations. Smoking around the time of an elective breast lift with implants can lead to significant complications and some of them can be impossible to fix. Always follow your surgeon's advice when it comes to not smoking before the procedure.
Thank you for your question. If you are trying to cover up nicotine use prior to surgery, then you are hurting no one other than yourself. Regardless of whether or not your surgeon does a nicotine test, if you are using nicotine around the time of surgery, this will increase your risk of complications from surgery by over 200%! So if after surgery you end up with an infection, skin necrosis, open wounds, etc., do not blame your surgeon, blame yourself. If you want to smart and be safe, and are using nicotine, be honest with your surgeon and reschedule your surgery. Be safe!
