Smoking, nicotine and surgery

Key takeaways

• Smoking and nicotine reduce blood flow and oxygen, which can slow healing and raise complication risk.
• Nicotine is part of the problem, so vaping and nicotine pouches can still affect healing.
• Many teams ask for a nicotine free window before and after surgery to support safe recovery.
• Stopping earlier makes a real difference to wound healing and infection risk.
• If you are unsure, tell us early so we can give you a firm plan and avoid last minute delays.

Why smoking and nicotine matter for surgery

Surgery depends on good blood flow and good oxygen delivery to the tissues. Your body needs both to heal properly. Smoking makes that harder. Nicotine narrows blood vessels and carbon monoxide reduces the amount of oxygen your blood can carry. That combination is bad news for wound healing.

The World Health Organization says smoking increases the risk of complications after surgery, including infection and delayed wound healing.

People sometimes assume the only risk is the anaesthetic. Anaesthetic matters, but in plastic surgery the bigger issue is often what happens after you go home. Healing takes weeks. The early days set the direction for scars, swelling and the final result.

If you are thinking "I only have a couple a day", it is not that straightforward. A small amount can still affect circulation. Bodies are not spreadsheets. You cannot always predict where the weak spot will be.

What can go wrong if you smoke or use nicotine around surgery

The risks vary by procedure, but the pattern stays the same. Smoking is linked with higher rates of infection, wound problems and breathing complications. Studies of surgical outcomes show smokers have higher postoperative complication rates.

Common problems surgeons worry about

• Delayed healing: wounds take longer to close and settle.
• Infection: reduced oxygen delivery makes it easier for infection to take hold.
• Wound breakdown: incision edges can struggle if tissue quality is reduced.
• Skin or tissue loss: especially where skin is lifted and re-draped.
• Less predictable scarring: scars can widen and remain red for longer.
• Chest and breathing issues: coughing, more mucus and higher risk around anaesthetic.

The American College of Surgeons states that quitting smoking 4 to 6 weeks before surgery and staying smoke free for 4 weeks afterwards can halve the rate of wound complications.

That is a big improvement for something that does not require a new medication or a new procedure. It requires timing and being open with your surgeon.

Which procedures are most sensitive?

Procedures that rely on fine blood supply and skin flaps are usually more sensitive. Examples include:

• Facelift and neck lift
• Blepharoplasty in some settings, depending on technique and patient factors
• Breast surgery
• Tummy tuck (abdominoplasty)
• Revision surgery where tissue has already been operated on

This does not mean smokers can never have surgery. It means the risk rises and many surgeons will advise delaying treatment until the odds look better. That lowers the risk to your recovery and your result.

Vaping, patches and pouches: is it the same?

This is where people get caught out. They stop cigarettes and switch to vaping or nicotine pouches and assume the problem is solved. From a healing point of view, nicotine is still a problem because it restricts blood flow.

Many surgical teams talk about being nicotine free instead of only smoke free.

If you are using nicotine replacement to quit (patches, gum or sprays), tell us early. We can advise you on the safest approach for your procedure and timeline. Do not assume. Different teams set different rules because procedure risk varies.

What we mean by nicotine

• Cigarettes and roll ups
• Vapes with nicotine
• Nicotine pouches
• Nicotine gum and lozenges
• Nicotine patches and sprays
• Shisha and other tobacco products

If you are not sure whether your product contains nicotine, check the packaging or tell us what it is and we will help you work it out.

How long do you need to stop for?

You will see slightly different timeframes depending on the procedure and the surgeon. The theme is consistent: stop in advance and stay stopped through early healing.

Here are a few credible reference points:

• The American College of Surgeons highlights quitting 4 to 6 weeks before surgery and staying smoke free 4 weeks after.
• North Tees and Hartlepool NHS guidance asks patients to stop at least 4 to 6 weeks before surgery where possible.
• Reviews of preoperative smoking cessation show fewer complications when patients stop ahead of time.

In practical terms, if you are thinking about surgery, tell us your nicotine status early. If the plan is to be nicotine free for 6 weeks before, it is better to plan for that from the start. It saves stress, it avoids rearranging dates and it avoids last minute uncertainty.

A quick reality check

Stopping a week before surgery is better than smoking on the day, but it is not the same as stopping several weeks before. Your circulation and oxygen delivery need time to improve. Think of it like turning up to a marathon with one training run: better than nothing, but not ideal.

What happens if you have not stopped

If you are still smoking or using nicotine close to surgery, we may advise delaying. That can be frustrating, but it is usually the safest call. A delayed date is annoying. A wound problem that needs treatment is worse.

What often happens in clinics:

• We ask early about smoking, vaping and nicotine products.
• We set a stop window based on the procedure and your risk profile.
• We confirm the plan before the final date is locked in.
• We delay surgery if the risk looks too high.

Being upfront helps you. It also helps the team plan properly and lower the risk to your result. If you are worried you cannot stop in time, tell us early and we can talk through options.

A practical quit plan

Quitting can be easy in theory and hard in real life. If you have tried before, you already know that. The goal here is getting you nicotine free for long enough to heal properly.

Step by step

1. Pick a quit date and put it in your calendar.
2. Remove the easy triggers: lighters, vapes, pouches, ashtrays, anything that makes it too convenient.
3. Tell someone: accountability helps, even if it is a mate who will take the mick.
4. Plan for cravings: short walks, chewing gum, cold water or a quick shower, anything that breaks the loop.
5. Ask what is allowed if you are using quitting aids. Do not assume.
6. Keep going after surgery: the first few weeks are when healing matters most.

The NHS has practical advice and services to help you quit.

If you slip up

If you slip up, tell us. Do not try to hide it. The goal is to keep you safe. Many delays happen because people feel embarrassed and keep it quiet until late in the process. Most adults do not need a telling off. They need a realistic plan.

Next steps

If you smoke, vape or use nicotine, the best move is to be upfront about it early. It helps us advise you properly and it avoids last minute delays. If you are not sure what counts as nicotine or how long you need to stop for, ask and we will give you a plan based on the procedure.

• Book a consultation and share your nicotine status in the form.
• Read about treatments and procedures and note down any questions you want to ask.
• Check the FAQs for common pre surgery questions.
• If you want help quitting, use the NHS stop smoking support.
