Smoking and a breast reduction (or breast lift or tummy tuck, for that matter) is a HUGE deal! You either need to quit or you need to postpone your procedure. Since it is an elective procedure (not an emergency), you should be in optimum shape or health prior to undergoing it. Nicotine causes vasoconstriction (blood vessels tighten so blood can't get through as easily), which decreases your body's ability to heal. During breast reduction, all of the cutting and removal of tissue interrupts circulation to the tissue that's left behind. Imagine if you took a chunk of highway out....all of a sudden the cars cannot pass and they have to find an alternative route. It's chaos for several weeks, right until either roads get fixed or travelers get used to new routes? Your body does the same when its normal blood vessels are interrupted by surgery. It has to find alternative routes. During this time, your tissue may not get enough circulation to survive. Nipples are the most vulnerable, but healing (in general) is also more difficult than just a normal "cut". Incisions may not heal, nipples may turn black or fall off--you definitely don't want that to happen, right? People can have trouble healing even without nicotine making it worse. Your chances of having complications rise automatically by over 50%!In addition, cigarettes cause you to inhale carbon monoxide which kicks oxygen off the red blood cells so they are not even carrying the right stuff to the healing tissues. Another strike against you....again, for elective surgery, it is not worth the risks.During the first 2 weeks after you quit, your lungs begin to clear out all the mucous and material that has built up from it not being able to do its normal functions. Your lungs mechanisms for clearing out material (cilia--little hair like processes which propel unwanted material from your lungs) are paralyzed by nicotine. That's why people who quit smoking normally cough for several days afterwards. That is not the best time to be put to sleep either. It's best to get past that phase prior to having anesthesia.Speak with your plastic surgeon and make the best choice for your long term health. Having healthy nipples seems like a good motivation to quit smoking if you really want to have a breast reduction!
