Does Vaping Cause Popcorn Lung?
No confirmed cases linked to vaping, and the chemical behind the scare is banned in UK e liquids since 2016. The myth and the facts.
Few vaping scares are as well known as popcorn lung, so it is worth answering clearly, does vaping cause popcorn lung? The reassuring, evidence based answer is that there have been no confirmed cases of popcorn lung linked to e cigarettes, and the chemical behind the scare, diacetyl, has been banned from e cigarettes and e liquids in the UK since 2016. So legal UK e liquids are not allowed to contain it. This guide explains where the myth came from and what the facts are.
Quick answer
There have been no confirmed cases of popcorn lung linked to vaping. The chemical that caused the original concern, diacetyl, has been banned from e cigarettes and e liquids in the UK and EU since 2016, so legal UK products are not allowed to contain it. Always choose regulated UK products.
Where the popcorn lung scare came from
Popcorn lung is the nickname for a rare condition, bronchiolitis obliterans, which damages the small airways. The name comes from cases among US popcorn factory workers around the year 2000, who developed the condition after breathing in large amounts of a flavouring chemical called diacetyl. This was a workplace exposure issue, not connected to vaping, but the link to a flavouring led to fears about e cigarettes.

Diacetyl is banned in UK e liquids
The crucial point for UK vapers is that diacetyl was banned as an ingredient in e cigarettes and e liquids in the UK and EU under the Tobacco Products Directive in 2016. That means legal e liquids sold in the UK are not permitted to contain it. While some early e liquids, particularly from overseas, did once contain diacetyl, regulated UK products today do not.
The chemical behind the popcorn lung scare is banned from UK e liquids, and there are no confirmed cases of popcorn lung from vaping. The key is to stick to regulated UK products.

A few more questions
Is popcorn lung a real condition?
Yes, bronchiolitis obliterans is real, but it has various causes and is not confirmed to be caused by regulated vaping.
Are illegal vapes a concern here?
Their contents are not controlled, so the safe choice is always regulated UK products from reputable sellers.
Why regulated products matter
The popcorn lung story is really a lesson in the value of regulation. Because UK rules ban diacetyl and set standards for what e liquids can contain, vapers who stick to regulated products are protected from the very ingredient that caused the original scare. That protection only applies to legal, compliant products, though.
Unregulated or illegal vapes are a different matter, as their contents are not controlled or tested, and they have been found to contain things they should not. This is why the consistent advice is to buy from reputable UK sellers and avoid anything that has not gone through proper regulation.
Regulated versus unregulated
| Aspect | Regulated UK products | Unregulated or illegal |
|---|---|---|
| Diacetyl | Banned, not permitted | Unknown, uncontrolled |
| Standards | Must meet UK rules | None guaranteed |
| Testing | Required | Not assured |
| Best choice | Yes | Avoid |

A quick word on safety and the law
Vaping 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.
