Here is the number that should make everyone pause: one in six people using nicotine pouches in Britain has never been a regular smoker. Not a former smoker reaching for a cleaner habit. Not a vaper switching across. Someone who came to nicotine through a small white pouch tucked under the lip, and nothing else.
That figure comes from the largest study of pouch use Britain has ever run, published in The Lancet Public Health in December 2025 by researchers at University College London. It reframes a debate that has been stuck for years. The question was always "are pouches safer than cigarettes?" The more uncomfortable question now is "who is actually putting them in their mouths, and why?"
Let us walk through what the researchers found, why the never-smoked finding matters so much, and what it means for you whether you use pouches, are thinking about it, or just want the honest version without the marketing gloss.
What did the UCL study actually measure?
The team analysed survey responses from 127,793 people across England, Scotland and Wales, all aged 16 and over, collected between October 2020 and March 2025. That is a serious sample size, large enough to track a habit as it moved from the fringe into the mainstream.
The headline trend is steep. Pouch use among adults rose from 0.1% in 2020 to around 1% by early 2025. In raw terms that is roughly 522,000 people. A decade ago almost nobody in Britain had heard of a nicotine pouch. Now half a million adults use them, and the curve is still climbing.
The study was funded by Cancer Research UK, which matters for context. This is not industry data dressed up as research, and it is not an anti-nicotine campaign group cherry-picking scary numbers. It is independent academic work, and it cuts in more than one direction.
Why is the "never smoked" figure the one that matters?
Public health policy on nicotine pouches rests on a single idea: harm reduction. The logic is simple. A smoker who switches to pouches drops the tar, the combustion and the thousands of toxic compounds in cigarette smoke. For that person, a pouch is almost certainly the lesser evil.
The UCL data backs part of that story. Most users, 69%, also smoke or vape, which fits the picture of pouches as a step away from cigarettes. Pouches even showed up as a quit aid in their own right, accounting for 6.5% of quit attempts in 2025. To put that in perspective, that is higher than prescription nicotine replacement therapy at 4.5% and the stop-smoking drug varenicline at 1.1%, though still well behind e-cigarettes at 40.2% and over-the-counter nicotine replacement at 17.3%.
So far, so reassuring. Then you hit the 16%.
One in six users never smoked regularly before picking up pouches. For these people the harm reduction argument collapses, because there was no harm to reduce. They did not trade cigarettes for a pouch. They added nicotine to a life that had none. As Dr Harry Tattan-Birch, the study lead from the UCL Institute of Epidemiology and Health Care, put it, whether pouches are good or bad depends entirely on who is using them. For never-smokers, the potential for harm only goes up.
Who is driving the surge?
The growth is not spread evenly across the population. It is concentrated, sharply, among the young and among men.
- Of everyone using pouches between 2022 and 2025, 72% were men.
- Just under half, 47%, were under the age of 25.
- Among men aged 16 to 24, usage hit 7.5%. That is roughly 1 in 13 young men.
This is not the profile of a product that mainly rescues middle-aged smokers from a 30-year habit. It is the profile of a product finding its biggest audience among people who, in many cases, were never heavy smokers to begin with. Young men in their late teens and early twenties are not the demographic that fills lung cancer wards. They are the demographic that builds new habits.
Dr Tattan-Birch was blunt about the reason behind the spike. He pointed to aggressive advertising across social media, billboards, bars and train stations. If you have walked through a British city centre in the past two years, you have probably seen the branding without registering it: clean, minimal, almost wellness-coded. Nothing about it reads as tobacco.
Is this a gateway, or just a cleaner alternative?
This is where honest people can disagree, so let us lay out both sides rather than pretend it is settled.
The optimistic reading: pouches are a tool. The 69% who also smoke or vape are the core market, and for them pouches are a genuine off-ramp from cigarettes. The 16% who never smoked are a minority, and some of them might have ended up smoking or vaping anyway, so a pouch could even be the least bad outcome.
The worried reading: a product that recruits half a million users in five years, skewed heavily toward under-25s, with one in six having no prior nicotine history, looks a lot like the early stages of a new dependency cycle. Nicotine is addictive regardless of how it is delivered. A 19-year-old who gets hooked on pouches is not healthier than a 19-year-old who never started, and "better than smoking" is a low bar when the realistic alternative was nothing at all.
Both readings can be partly true at once. That is exactly why the never-smoked number is so awkward. It refuses to let pouches be purely good or purely bad.
How does British law respond to all this?
For most of this surge, the regulatory cupboard was bare. Until recently you could legally sell a high-strength nicotine pouch to a 14-year-old, with no marketing limits and no cap on how much nicotine a single pouch could contain. That gap is finally closing, but slowly.
The Tobacco and Vapes Act received Royal Assent on 29 April 2026. The first hard deadline follows on 29 October 2026, when it becomes illegal to sell nicotine pouches to anyone under 18. After that comes the advertising and sponsorship ban, which takes effect from 1 June 2027 and will strip pouches of the billboards, social campaigns and festival deals that fuelled their rise.
One thing the law has not yet pinned down is strength. Britain still has no legal cap on nicotine content, which is why some products on shelves reach eye-watering levels far above the 20mg per pouch that campaigners and parts of the industry now treat as a sensible ceiling. A consultation on strength limits is expected, but it has not landed.
Read in light of the UCL findings, the timing of these rules looks reactive rather than proactive. The age limit arrives after half a million people already use pouches. The ad ban arrives a full year later still. The strength cap is not even written yet.
If you use pouches, what should you take from this?
The study is not a reason to panic, but it is a reason to be honest with yourself about which group you fall into.
If you switched from cigarettes, the evidence still supports your choice as the lower-risk option, and that has not changed. If you switched from vaping, you have swapped one nicotine source for another with a different risk profile, neither of them risk-free. If you came to pouches having never really smoked, it is worth asking the plain question: what is this giving you that is worth a nicotine habit you did not have before?
None of that is a lecture. It is the same calculation the researchers are making, just at the level of one person instead of a population. Nicotine is genuinely addictive, the strongest pouches deliver a lot of it, and the absence of smoke does not mean the absence of dependence.
What happens next?
Expect three things. The age-of-sale rule in October 2026 will, on paper, cut off the youngest new users, though enforcement in corner shops is a separate battle. The 2027 advertising ban will quietly remove the marketing engine that made pouches feel aspirational rather than addictive. And sooner or later a strength cap will force the high-dose products off the shelves.
The deeper question the UCL study raises will outlast all of that. Britain has spent decades pulling people away from nicotine. Pouches have, in five short years, pulled some people back toward it, including people who were never there to begin with. Whether that counts as harm reduction or harm creation depends, as it always has, on who is reaching for the tin.
Frequently asked questions
How many people in the UK use nicotine pouches?
The 2025 UCL study estimates around 522,000 adults, or roughly 1% of the population. Use rose tenfold from 0.1% in 2020 to about 1% by early 2025.
What percentage of pouch users never smoked?
One in six, about 16%, had never regularly smoked before using pouches. The remaining majority, 69%, also smoke or vape.
Are nicotine pouches safer than cigarettes?
For someone switching from smoking, pouches remove tar, combustion and smoke, so they are widely considered lower risk than cigarettes. They are not risk-free, and for a person who never smoked there is no risk being reduced, only nicotine being added.
Why are young men using nicotine pouches so much?
The UCL study found 72% of users were men and 47% were under 25, with usage among 16 to 24 year old men reaching 7.5%. Researchers linked the surge to heavy advertising on social media, billboards, bars and train stations.
Can nicotine pouches help you quit smoking?
They appear to help some people. Pouches accounted for 6.5% of UK quit attempts in 2025, higher than prescription nicotine replacement therapy and varenicline, though far below e-cigarettes.
When does the UK ban selling nicotine pouches to under-18s?
From 29 October 2026, under the Tobacco and Vapes Act that received Royal Assent on 29 April 2026. A separate advertising and sponsorship ban follows on 1 June 2027.
Is there a limit on how strong a nicotine pouch can be in the UK?
Not yet. Britain currently has no legal cap on nicotine content, though a 20mg per pouch ceiling is widely discussed and a government consultation on strength limits is expected.
Does using pouches without smoking still cause addiction?
Yes. Nicotine is addictive regardless of how it is delivered. Using pouches without ever smoking means starting a nicotine dependence rather than replacing an existing one.
