That's the wrong question to be asking, and the wrong way to look at this. This is more about optimizing your chances for a successful outcome, than it is about passing a test. I ask patients to stop nicotine at least 4 weeks before surgery, if not 6, and plan to never resume. Breast implants and smoking do not mix. Smokers have a higher chance of capsular contracture than non-smokers, and can result in needing additional surgeries down the line. Also, nicotine temporarily constricts blood vessels, making it harder to heal any surgical site, and putting you at a greater risk overall. Smokers also have a higher incidence of deep venous thrombosis, which is a possible risk of tummy tuck surgery, and one that has the potential to be fatal. When you are ready to make as big of a change as a breast aug, tummy tuck, and lipo will give you, isn't it worth it to give yourself the gift of not smoking as well? Your skin will look better too. ;)
