Smoking adversely affects wound healing. The small vessels that supply blood to the tissues shrink up and prevent the necessary nutrients for healing to get to the wound. The incidence of having a wound complication such as an open wound or skin death is much higher in smokers. Furthermore, the rate of wound infection is also significantly increased in smokers for the same reason of limited blood flow. Because of this, a patient must stop smoking for a minimum of two weeks prior to surgery to decrease the risk of these complications.
