You quit smoking! Don't go back.... Using tobacco products brings a significant risk of cancer, stroke, heat attack, etc. From a Plastic Surgery standpoint it is a vasoconstrictor. Wound healing is all about getting oxygen and needed entities to the wound. It is well known that patients who smoke have a tremendous increase in their rate of serious complications, (infections, wounds falling apart, etc.). Nicotine is the main vasoconstrictor, so getting a patch or lozenge of nicotine won't help the vasoconstriction. Best to be off the tobacco/nicotine entirely before surgery. A breast lift by definition places the wound on tension. Tension is also a risk factor for wounds. Please be honest with your Board Certified Plastic Surgeon. Together you can make a plan. The amount of time to be nicotine free, (before and after the surgery), will depend on the procedure and the individual surgeon.
