Hello! Thank you for your question! The issue with nicotine, or any inhalational agent, in that it also acts as a vasoconstrictor, clamping down of blood vessels. Blood supply is always of great concern during any surgical procedure, but especially in such a procedure as a breast augmentation where the viability of the nipple-areolar complex is obviously important. Since the vascularity to the area is already tenuous with placement of the implant beneath, maximizing blood flow to the tissue is critical. In addition, your respiratory system may be compromised, and potentially have adverse effects with general anesthesia.Typically, we recommend at least 6 weeks of smoking cessation prior to and at least 6 weeks after any surgical procedure. The longer, the better. Nicotine always increases the risk for infection, nipple necrosis, and wound complications, as well as other health consequences. The most devastating consequence is infection, especially since an implantable prosthetic device is used, is increased. This along with wound healing and scarring. I would discuss this with your surgeon prior to your procedure. Hope that this helps! Best wishes!
