Marijuana before rhinoplasty. Will it affect my results?

Safety should always be the
primary concern in any procedure. The goal of all plastic surgeons that perform
rhinoplasties is to improve the appearance with minimal side effects or problems. Smoking anything may increase the risks of complications with a surgical procedure like a rhinoplasty. This includes "vaping". Smokers have a significantly
higher rate of delayed healing, infection, opening of the incisions, necrosis
or loss of the facial skin that is elevated and the underlying tissue, poor
scarring, and anesthesia problems.
Be honest with your plastic
surgeon who should be certified by the American Board of American Plastic
Surgery and ideally a member of The American Society for Aesthetic Plastic
Surgery (ASAPS) or a facial plastic surgeon (otolaryngologist) about your exposure to smoke and follow all of her or his instructions.
Remember that you are a participant in your own care.

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! 

 It's always best to check with your  Operative surgeon prior to the surgery, since they are the ones that  are performing your surgery. Smoking any type of product can have deleterious effects on healing process after cosmetic surgery due to nicotine and carbon monoxide. You may stand a higher risk of infection. Taking Excedrin which has aspirin in it can lead to nosebleeds which can be rather significant after a rhinoplasty procedure.
