Cigarettes contain nicotine which is a powerful vasoconstrictor. This means the chemical chokes all of your blood vessels in your body.
Decreased blood supply means potentially delayed or poor healing and will increase your risk of infection, wound break down and possible need for additional surgery.
Our minimum recommendation for patients who smoke is to stop smoking at least 4 weeks before surgery and resume (hopefully never!) 4 weeks after surgery.
Please note nicotine gum, patch, and second hand smoke are just as bad.
