Your clinic sends the pre-operation checklist and one line says no smoking. You have a flight in five weeks and a vape in your pocket. Do you have to stop, and for how long?

Key takeaways

  • The WHO reports that smokers who quit about 4 weeks or more before surgery have a lower risk of complications and better results 6 months later.
  • Three UK hospital leaflets on nose surgery tell patients to stop smoking or cut down afterwards (Coventry, Aneurin Bevan, Gloucestershire); two more ask patients to avoid smoky air, one of them for two weeks.
  • Three studies of nose surgery patients found no significant difference in complications between smokers and nonsmokers, and two of them still recommend quitting.
  • The NHS says vaping is less harmful than smoking but not risk-free, and the nose-surgery leaflets give no separate rule for it.

The sources split by what they cover. The WHO says smokers who quit about 4 weeks or more before surgery have a lower risk of complications. Three UK hospital leaflets on nose surgery tell patients to stop or cut down afterwards. The studies that looked at smokers having rhinoplasty did not find significantly more infections or revisions, though two of those papers still recommend quitting. Your surgeon and anaesthetist set the rule that applies to you.

Should you stop smoking before rhinoplasty?

Surgical teams generally ask for it, and the evidence behind that comes from surgery in general, not from noses. The World Health Organization (WHO) said in a January 2020 release that smokers who quit approximately 4 weeks or more before surgery have a lower risk of complications and better results 6 months afterwards, and are less likely to have anaesthesia complications. The same release says smoking can delay healing and raise the risk of infection at the wound site, and that each tobacco-free week after the fourth improves health outcomes by 19%.

A 2023 briefing from ASH (Action on Smoking and Health) and the Royal College of Surgeons of Edinburgh adds two points. It cites the Royal College of Physicians for smokers being twice as likely to have delayed healing, surgical site infection and wound complications. It also says some surgeons will not operate until a patient can abstain from smoking, and that for people who cannot quit, the Royal College of Anaesthetists advises giving up for at least several weeks before surgery and not smoking on the day.

Both documents cover operations of every kind. Neither is about rhinoplasty, which is why the next section matters.

What do studies of smokers having nose surgery show?

Less than the general advice suggests. Four papers are worth knowing, and they point in slightly different directions:

Study Who What it found
Tugertimur and colleagues, Plastic and Reconstructive Surgery 1,884 open rhinoplasties: 80 active smokers, 39 former smokers, 1,765 nonsmokers No significant difference in revision, infection or wound complications. Revisions: 3.8% in smokers, 3.3% in nonsmokers. Antibiotics for cellulitis: 3.8% against 1.6%, all resolved
Erol and colleagues, Aesthetic Plastic Surgery (2022) 598 septoplasty and septorhinoplasty patients No difference in complications, revisions or breathing scores at 6 months between never, former and current smokers
Chan and colleagues, Otolaryngology-Head and Neck Surgery (2025) 67 septorhinoplasty patients, blood cotinine measured on the day of surgery No wound complications in the 13 cotinine-positive patients; 4 in the cotinine-negative group
Bouhadana and colleagues, Plastic Surgery (2024) Review of 82 aesthetic surgery studies Smoking raised complication risk for most procedures, but not significantly for rhinoplasty or mastopexy

Cotinine is a substance the body makes from nicotine; a blood test for it shows recent tobacco use more reliably than a patient’s own report.

Read the table with its limits in mind. The Tugertimur group had only 80 active smokers. Its authors write that the nose’s strong blood supply may soften smoking’s effects and that cessation should still be recommended, though it may not be mandatory. Erol’s group says surgeons should still suggest quitting. Bouhadana’s team warns that its rhinoplasty result may be biased and should be re-checked. None of the three says that smoking is harmless.

Our guide to what to do before nose surgery covers the same studies in its preparation checklist. Our page on columellar necrosis after revision rhinoplasty looks at what is known about smoking and wound healing in revision surgery.

What do hospital leaflets say about smoking after surgery?

Five UK leaflets address smoke after nose surgery. Three speak to the patient’s own smoking and all five to dust, crowds or smoke in the air:

Leaflet Smoking Smoky air
Aneurin Bevan University Health Board (septorhinoplasty) “Strongly advised to stop smoking as this impairs healing and contributes to persistent nasal symptoms” Keep away from smoky or dusty places and crowds to avoid infection
Coventry and Warwickshire (rhinoplasty discharge advice) “If possible, reduce or stop smoking in order to help the healing process” Avoid dusty or smoky places and crowded places for 1 week
Gloucestershire Hospitals (septoplasty) Avoid or cut down on smoking, because it affects healing and irritates the inside of the nose No smoke rule; avoid crowded or dusty places for 1 week
Royal Berkshire (septorhinoplasty, October 2026) No smoking rule Avoid smoky or dusty atmospheres for two weeks, as it irritates the inside of the nose
Cambridge University Hospitals (septorhinoplasty) No smoking rule Try to stay away from smoky places; rest at home away from crowds and smoky places

The leaflets give two reasons: slower healing, and irritation of a nasal lining that is already swollen and crusted. Aneurin Bevan adds the effect on lasting symptoms. Cambridge says it may take up to three months for the nose to settle and for breathing to be clear again, a stretch in which a smoky room works against you.

Four of the five leaflets are for septoplasty or septorhinoplasty, which includes work on the septum inside the nose, so they may describe a bigger operation than a cosmetic-only rhinoplasty. Smoke also reaches a nose through other people’s cigarettes. On the trip that means smoking terraces and shared hotel balconies, and the first two weeks at home or in a hotel room are when the leaflets want the nose left alone. Smell is often dulled early on; see smell after rhinoplasty.

A woman with a nasal splint sits on a hotel bed looking at a street terrace below the window where two people are smoking.

Is vaping safer than smoking around surgery?

The NHS says nicotine vaping is less harmful than smoking and also says it is not risk-free. Its page on vaping to quit smoking says vaping exposes users to fewer toxins and at lower levels than cigarettes, that most of the harmful chemicals in tobacco smoke, including tar and carbon monoxide, are not in vape aerosol, and that the long-term effects are not known yet. It calls the healthiest option not to smoke or vape.

The ASH and Royal College of Surgeons of Edinburgh briefing says the evidence to date has not identified any major concerns about e-cigarettes around surgery, and that nicotine replacement therapy is sold over the counter as gum, patches, strips, lozenges, microtabs and mouth or nasal sprays. Nicotine replacement therapy means products that give you nicotine without smoke.

Two gaps remain. The four nose-surgery studies above report on cigarette smoking or tobacco use; their abstracts give no separate result for vaping. And none of the five leaflets gives a vaping rule, so the clinic’s own instruction is the one to ask for.

What about the day of the operation?

The NHS lists “do not smoke” among the things to avoid for at least 24 hours after a general anaesthetic, along with driving, alcohol and important decisions. The same page says the anaesthetic’s effects can last around 24 hours. Fasting rules before the operation are a separate matter; the general anaesthesia guide covers them. Whether a nicotine product counts during fasting is for your anaesthetist to answer.

How do you count back from your surgery date?

If your surgeon asks for 4 weeks, you can work it out from the date. Take an operation on Monday 14 December 2026. Four weeks earlier is Monday 16 November, so a last cigarette on or before that day fits a 4-week rule. Two weeks of smoke avoidance after surgery, the Royal Berkshire figure, runs to Monday 28 December. These are the leaflet and WHO figures put on a calendar. Your own dates come from your team.

If you want help stopping, the ASH briefing says smokers are three times more likely to succeed with a local stop-smoking service than unaided. Readers in the UK can reach the free NHS helpline on 0800 169 0 169, listed in the Cambridge leaflet. Abroad, the local equivalent is a question for your GP before you travel.

What should you ask your surgeon?

  • Do you require me to stop smoking or vaping before surgery, and how many weeks ahead?
  • Does that rule cover vapes, nicotine patches, gum and sprays?
  • Will you test for nicotine, such as a cotinine test, before operating?
  • What do you want from me after surgery, and for how long?
  • If I do not stop, will you still operate, and what changes in your plan?
