How soon after Rhinoplasty is it safe to start smoking again without affecting the healing process or causing any complications?

The healing process is particularly active for 6 weeks (called the proliferative phase) and takes close to 6 months after any surgery to truly assess the results. However, we typically advise our patients to avoid smoking a month before and after.

Thank you for the question. You should absolutely consult with your physician about your smoking habits in order to obtain the most reliable and individualized medical advice. Most specialists recommend abstaining from smoking for 2-3 weeks before a rhinoplasty, while others may insist on a full month or two. Smoking will cause irritation and restrict the blood flow to your healing areas, possibly causing complications during the recovery period.   
In addition, you should also make sure to avoid smoking for at least two weeks after surgery as it may interfere with your healing process. Smoking after surgery may restrict the flow of blood to the healing areas, exacerbate swelling, and prolong recovery. Of course, as a physician, I would advise you to quit smoking altogether due to a variety of health risks associated with it. 
 An in-person exam with a board-certified plastic surgeon would be the best way to assess your needs and obtain expert medical advice. Best of luck!
