Far less harmful to the lungs than smoking, with no burning or tar, but not risk free. Some irritation can occur and long term effects are still studied.

A natural question for anyone vaping or thinking about it is what vaping does to your lungs. The balanced answer is that vaping is substantially less harmful to the lungs than smoking, because there is no burning tobacco, but it is not risk free, can cause some irritation, and its long term effects are still being studied. This guide explains, alongside our guide on whether vaping is bad for you.

Much less harmful than smoking

The clearest point is that, for the lungs, vaping is far less harmful than smoking. Cigarettes burn tobacco, filling the lungs with tar and many toxic chemicals that cause serious lung disease. Vaping heats an e liquid instead, with no burning and no tar, which is why UK public health bodies regard it as substantially less harmful for smokers who switch.

Vaping and your lungs

Aspect	Detail
Versus smoking	Far less harmful to the lungs
No burning tobacco	No tar or carbon monoxide
Possible short term effects	Throat or airway irritation, coughing
Long term effects	Still being studied
Serious illness cases	Linked to illegal THC vapes, not UK nicotine vapes

But not risk free

Less harmful than smoking does not mean harmless. Some people experience throat or airway irritation, a dry cough or similar when vaping, and because vaping is relatively new, the long term effects on the lungs are still being studied. It is worth noting that the serious lung illnesses reported in the news were linked to illegal THC vapes containing vitamin E acetate, not to UK regulated nicotine vapes.

Vaping is far less harmful to the lungs than smoking, with no burning or tar, but it is not risk free. Some irritation can occur, and long term effects are still being studied.

Frequently asked questions

What does vaping do to your lungs?

It is substantially less harmful to the lungs than smoking, with no burning or tar, but it is not risk free and can cause some irritation.

Is it safer than smoking for the lungs?

Yes, far less harmful, because there is no burning tobacco, tar or carbon monoxide.

Can vaping irritate the lungs or throat?

Some people get throat or airway irritation or a dry cough; this varies between people.

What about the serious lung illnesses reported?

Those were linked to illegal THC vapes containing vitamin E acetate, not UK regulated nicotine vapes.

Are the long term lung effects known?

Vaping is relatively new, so long term effects are still being studied, but it is far less harmful than smoking.

The bottom line

For the lungs, vaping is substantially less harmful than smoking, because it heats an e liquid rather than burning tobacco, so there is no tar or carbon monoxide. It is not risk free, though: some people experience throat or airway irritation or a dry cough, and because vaping is relatively new, the long term effects are still being studied. The serious lung illnesses reported in the news were linked to illegal THC vapes, not UK regulated nicotine vapes, and vaping remains for adult smokers, not non smokers.

• Can cause some throat or airway irritation
• Long term effects still being studied
• Serious illness cases linked to illegal THC vapes

Putting the lung risk in context

It is worth putting the lung picture in context. The dramatic lung illnesses that made headlines a few years ago were traced to illegal THC vapes containing vitamin E acetate, not to UK regulated nicotine vaping products. Similarly, the chemical linked to popcorn lung has been banned from UK e liquids since 2016, with no confirmed cases from them.

That does not make vaping risk free, some people do get throat or airway irritation, and the long term effects are still being studied. But it does mean the lung risks of UK regulated vaping are far lower than smoking and not the same as the illegal product scares.

A few more questions

Will vaping make me cough?

Some people get a dry cough or throat irritation, especially at first or at higher strengths; it often settles or eases with a lower strength.

Do and don’t

Do

• Switch completely if you are a smoker
• See vaping as far less harmful to the lungs than smoking
• Try a lower strength if you get irritation
• Avoid illegal or unregulated vapes

Try not to

• Treat vaping as completely safe for the lungs
• Keep smoking as well as vaping
• Use illegal THC vapes
• Start vaping if you are a non smoker

Reducing any irritation

If vaping irritates your throat or airways, a few simple changes often help. A lower nicotine strength can reduce a harsh throat hit, staying hydrated helps with dryness, and a gentler, slower draw is easier on the airways than hard, sharp puffs. Giving your body a little time to adjust when switching from smoking can also make a difference.

Sticking to UK regulated products from reputable sellers matters too, since the serious lung problems reported elsewhere were linked to illegal, unregulated vapes. If irritation persists or you are worried, it is always sensible to speak to a pharmacist or GP.

Easing irritation

Step	Why it helps
Lower strength	Reduces harsh throat hit
Stay hydrated	Helps with dryness
Gentle, slow draw	Easier on the airways
Regulated products	Avoids illegal vape risks
Persisting issues	See a pharmacist or GP

Can my lungs recover after switching from smoking?

Many people notice improvements after switching completely from smoking; for personal advice, speak to a GP.

A quick word on safety and the law

Vaping and nicotine products are intended for adult smokers and existing vapers as a less harmful alternative to cigarettes. They contain nicotine unless stated otherwise, which is addictive, and they are not suitable for non smokers, pregnant women or anyone under 18. By law you must be 18 or over to buy vaping products in the UK, and we age verify every order. If you want to stop using nicotine altogether, your local stop smoking service offers free, tailored support.

UK public health bodies advise that vaping is substantially less harmful than smoking, but it is not risk free, and if you do not smoke the advice is not to start.
