Can You Vape Before Surgery?

Why vaping before an operation carries real risks and what your surgical team needs to know.

Quick answer: You should not vape immediately before surgery and ideally should stop for as long as possible beforehand. Nicotine affects circulation, wound healing, anaesthetic response and cardiovascular risk during operations. Always tell your surgical team that you vape.

If you are scheduled for surgery, whether a minor day procedure or a major operation, what you do in the days and weeks beforehand matters. Vaping and nicotine use are directly relevant to surgical risk and recovery.

How Nicotine Affects Surgical Risk

Risk factor	How nicotine contributes	Clinical significance
Wound healing	Nicotine constricts blood vessels, reducing oxygen delivery to tissue	Higher risk of slow or poor wound healing post-surgery
Infection risk	Impaired circulation reduces immune response at wound site	Increased risk of post-operative infection
Cardiovascular stress	Nicotine raises heart rate and blood pressure	Greater cardiovascular strain during and after surgery
Anaesthetic interaction	Nicotine affects how the body metabolises some anaesthetic agents	May require adjusted dosing; harder to achieve stable anaesthesia
Blood clotting	Nicotine can increase platelet aggregation	Slight increase in clotting risk during and after surgery

How Far in Advance Should You Stop?

The longer you stop before surgery, the better. Even stopping 24 hours before reduces some of the acute cardiovascular effects. Stopping 4 to 8 weeks before surgery gives wound healing and circulation the best chance of recovering to a healthier baseline.

Always Tell Your Surgical Team

Being honest with your pre-operative assessment nurse and surgeon about vaping is essential. They are not there to judge you: they need accurate information to plan your anaesthetic, manage your cardiovascular risk and advise on wound care. Withholding this information can lead to complications that could have been anticipated and managed.

Important: This page provides general information only. Your surgeon and anaesthetist are the right people to advise on your specific situation. Always follow their pre-operative instructions exactly.

On the Day of Surgery

Do not vape on the morning of surgery
Do not use nicotine patches or pouches without checking with your surgical team first
Do not assume vaping is fine because it is different from smoking: the risks overlap significantly

Tell your anaesthetist and nurse that you vape, including how frequently and what strength
Follow the nil by mouth instructions provided: these apply to vaping too
If you have managed to reduce or stop ahead of the operation, tell your team so they have an accurate picture

Frequently Asked Questions

Mostly yes. The surgical risks associated with vaping are driven largely by nicotine, which is the same substance in both cigarettes and nicotine-containing e-liquids. Some risks from smoking: particularly those related to combustion byproducts and carbon monoxide in the blood: are lower with vaping. However, the core nicotine-related risks to wound healing, circulation and anaesthetic response are shared.

Nicotine replacement therapy (NRT) such as patches, gum or lozenges still delivers nicotine and carries some of the same pre-operative concerns. However, NRT is often preferred over vaping by surgical teams because the dose is more controlled and the route of delivery (transdermal or oral) does not involve inhaling. Discuss NRT use with your surgical team ahead of the operation.

Nicotine causes vasoconstriction: narrowing of blood vessels: which reduces the flow of oxygen-rich blood to healing tissue. Wounds require good blood supply to close properly, build new tissue and fight off infection. Impaired circulation slows all three processes. This is why surgeons particularly advise stopping nicotine ahead of procedures involving significant tissue repair, such as plastic surgery, joint replacements and abdominal operations.

This is a question for your surgeon, as it depends on the type of operation and your recovery progress. In general, the same nicotine-related concerns about wound healing and circulation apply during recovery as they do before surgery. Many surgeons advise stopping for several weeks post-operatively as well as pre-operatively for best healing outcomes.
