How Long After Rhinoplasty Can I Smoke Marijuana?

It’s important that patients stop smoking both cigarettes and marijuana for at least two weeks prior to rhinoplasty surgery. They should also avoid smoking for at least two weeks following surgery as well.
                Since marijuana doesn’t contain nicotine, it doesn’t cause the significant vasoconstriction that cigarette smoking causes. Despite this, smoking marijuana can have a negative impact upon breathing and airway function. For these reasons, it’s important to discuss this issue with your plastic surgeon before undergoing rhinoplasty surgery.

Tobacco or nicotine is not advised before and after any elective surgical procedure since nicotine is a vasoconstrictor that can decrease blood flow, and impair wound healing. Marijuana may not have vasoconstrictive properties, but smoking or vaping anything is irritating to both the lungs and the nose. Consider abstinence for a month. Thank you. Dr Joseph

I ask my patients not to smoke cigarettes, vape, or smoke marijuana for 4 weeks before and after surgery. Doing so can affect the outcome of the surgery, such as the wound healing of the laceration. For an elective cosmetic procedure, we want to make sure everything possible is done to maximize the outcome. You've come so far, don't give up now!

Thank you for your question. It's best to avoid smoking for at least two weeks prior to rhinoplasty. This applies not only to conventional cigarettes, but also to marijuana. Also make sure to avoid smoking marijuana 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.  I'd recommend to consult with your plastic surgeon as he or she may have different guidelines for smoking. 
An in-person exam with a board certified plastic surgeon is always the best way to fully assess your needs and address your concerns. Best of luck!

Ensure that you are breathing normally prior to even considering using marijuana.  It will be at least 3 - 4 weeks depending on how you heal.
