Nicotine test for breast aug, tummy tuck and lipo

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. ;)

You should stop smoking at least 4 to 6 weeks prior to tummy tuck surgery.  The fact that the test doesn't detect metabolites means absolutely nothing about your risks for wound healing complications.  If you have smoked -- even a single cigarette -- within that time frame the data indicates that you are at higher risk for tissue necrosis and wound healing problems.

I would think that if you have stopped smoking and your nicotine test is negative then you should be fine to safely undergo a tummy tuck.
