Tobacco harm reduction is a public health approach that accepts some adults will keep using nicotine and tries to move them away from smoking, the most damaging way to take it, towards non-combustible products such as snus, nicotine pouches and vapes. It sits alongside quitting, not in place of it. The idea is simple: if the smoke causes most of the harm, removing the smoke should cut the risk, even though nicotine itself stays addictive.
Below we look at what the concept means, where pouches and snus fit, what the numbers from the UK, Sweden and the rest of Europe show, and how UK law treats these products.
What tobacco harm reduction means in practice
Most tobacco control policy works by restriction: smoke-free public places, age limits on sales, advertising bans and higher prices. These measures matter, yet cigarettes remain on sale almost everywhere and plenty of smokers either cannot or will not give up nicotine. Harm reduction adds a different lever. Instead of only taking things away, it offers smokers a lower-risk route and gives them reasons to take it.
The term is borrowed from wider drug policy, where it describes any measure that lowers the damage done by a substance without demanding total abstinence. Applied to tobacco, "harm" works on three levels: the health of the person smoking, the health of people around them who breathe second-hand smoke, and the cost to the health system of treating smoking-related disease.
A complement to quitting, not a replacement
Supporters of the approach are clear that it should run next to existing measures. Free stop-smoking services and licensed nicotine replacement therapy (patches, gum and similar products) remain the first port of call for anyone who wants to stop altogether. A harm reduction nicotine strategy is aimed at the group those services do not reach: smokers who have tried and failed, or who have no intention of giving up nicotine.
Is it just swapping one addiction for another?
This is the most common objection, and it is fair as far as it goes. Pouches, snus and vapes all contain nicotine, so the dependence remains. The point is that harm reduction measures success by disease and deaths avoided, not by whether nicotine use ends. If someone keeps using nicotine but stops inhaling burning tobacco, the goal of the strategy has been met, even though the habit has not gone away.
Why the cigarette is the real target
The scale of the problem explains why governments and researchers keep returning to this idea. According to the World Health Organization's tobacco fact sheet, tobacco kills more than 7 million people every year, including over 1.6 million non-smokers exposed to second-hand smoke. Around 80% of the world's 1.2 billion tobacco users live in low- and middle-income countries, where access to cessation support is often thin.
What makes smoking so damaging is combustion. Burning tobacco produces tar and gases containing thousands of harmful substances, and the Global State of Tobacco Harm Reduction (GSTHR) project describes burning a cigarette and inhaling the smoke as the most dangerous way to consume nicotine. Nicotine is what keeps people coming back, but it is the smoke that carries most of the disease risk.
That distinction is easy to miss. In its 2022 health assessment of nicotine pouches, Germany's Federal Institute for Risk Assessment (BfR) noted that the Dutch institute RIVM had found no evidence of carcinogenic properties of nicotine in its monograph on pouches, while also citing a review which concluded that nothing can yet be said about possible tumour-inducing effects of long-term nicotine use. None of this makes nicotine harmless: the WHO describes it as highly addictive and harmful, especially for young people.
Where snus and nicotine pouches sit on the risk spectrum
GSTHR groups non-combustible products together as "safer nicotine products", a label meaning less harmful than smoking rather than harmless. The group includes vapes, heated tobacco, Swedish-style snus and tobacco-free nicotine pouches. Here is how they differ from a cigarette in the way nicotine is delivered.
| Product | Burns tobacco? | Contains tobacco leaf? | How nicotine is taken |
| Cigarette | Yes | Yes | Smoke inhaled into the lungs |
| Heated tobacco | No, heated only | Yes | Aerosol inhaled |
| Vape (e-cigarette) | No | No | Aerosol inhaled |
| Swedish-style snus | No | Yes | Pouch held under the lip |
| Nicotine pouch | No | No | Pouch held under the lip |
For pouches, the BfR assessment pointed to tobacco-specific nitrosamines (TSNAs), compounds proven to be carcinogenic. Because pouches use extracted nicotine rather than tobacco leaf, TSNAs appear at most in very small traces, left over from the extraction process. There is no smoke, so no tar either.
In the UK, the most-cited evidence concerns vaping rather than pouches. The Office for Health Improvement and Disparities' 2022 evidence update found that vaping leads to a substantial reduction in biomarkers of toxicant exposure compared with smoking. The same report stresses that any residual risk remains unclear and that people who have never smoked should be discouraged from starting. That is the honest shape of the evidence for every product on this list: lower exposure than smoking, not zero risk.

The public health case: what the data shows
Policy makers increasingly frame tobacco harm reduction as a population-level tool. Harry Shapiro, lead author of the GSTHR 2024 report, put it this way: if fully realised, it "has the potential to rapidly reduce the global number of smokers", which he called one of the greatest public health gains of the 21st century. The same report estimates that the number of vapers worldwide rose from 58 million in 2018 to 114 million, with a further 30 million or so using other safer nicotine products, and that more than two thirds of the world's adults across around 130 countries have legal access to at least one such product.
Smoking rates show how far countries still have to go, and how differently they have travelled.
| Country or region | Adults who smoke | Source and year |
| United Kingdom | 11.9% (around 6.0 million people aged 18+) | ONS, Adult smoking habits in the UK, 2023 |
| Sweden | 8% | Special Eurobarometer 539, 2023 |
| EU-27 average | 24% | Special Eurobarometer 539, 2023 |
| Germany | 28.2% (moving average) | DEBRA study, October 2024 |
These surveys use different methods and age bands, so treat the comparison as a broad picture rather than a league table. The UK figure, published by the Office for National Statistics, is the lowest since its records began in 2011. The same ONS release estimates that 9.8% of adults in Great Britain (about 5.1 million people) vape daily or occasionally.
The Sweden smoking rates story
Sweden is the example everyone in the snus public health debate reaches for. In the European Commission's Special Eurobarometer 539, Sweden had the lowest share of smokers in the EU at 8%, a third of the EU average. Swedish national reporting puts daily smoking even closer to 5%, the threshold commonly used to define a "smoke-free" country.
What makes the case striking is that Swedes have not stopped using nicotine. Speaking at a harm reduction conference at the Charité in Berlin in March 2025, tobacco researcher Karl Fagerström said Sweden's nicotine use, at around 22%, is similar to Germany's, yet the country has hardly any smokers and the lowest lung cancer rate in the EU. His conclusion was that snus and nicotine pouches are key to reducing consumption-related risks.
There are caveats. A single country cannot prove cause and effect on its own, and other policies may also play a part. Still, the pattern of high nicotine use, low smoking and low smoking-related disease is the strongest real-world argument harm reduction advocates have.
Lessons from New Zealand and Germany
Other countries offer contrasting results. At the same Berlin conference, Ben Youdan of ASH New Zealand described a government campaign that informed smokers about lower-risk alternatives and offered free vape starter kits, and said vaping now plays a major role in reducing New Zealand's smoking rate.
Germany shows the other side. Conference organiser Prof. Heino Stöver pointed to around 127,000 tobacco deaths a year in Germany and complained that cigarettes are available around the clock while pouches are pushed onto the grey market by local sales bans. Policy consultant Clive Bates summed up the risk of prohibition neatly: banning a product "does not mean that it disappears", it just changes who sells it.
What UK law says about snus and pouches
The UK takes a mixed position. Under the Tobacco for Oral Use (Safety) Regulations 1992, no one may supply, offer to supply or possess for supply any tobacco for oral use. The regulations define that as a product made wholly or partly of tobacco, intended for oral use (other than smoking or chewing), in powder or particulate form, including sachet portions. Traditional Swedish snus falls squarely within that definition, so it cannot lawfully be supplied in the UK.
Tobacco-free nicotine pouches are different. They contain no tobacco leaf, so they sit outside the 1992 definition.

Myths and facts at a glance
| Common claim | What the evidence says |
| "Nicotine is what causes cancer." | Germany's BfR reports that the Dutch health institute RIVM found no evidence nicotine is carcinogenic; combustion and compounds such as TSNAs are the main concern. Nicotine is still addictive. |
| "Pouches are completely risk-free." | No product containing nicotine is risk-free. The case is that risk is lower than smoking, not absent. |
| "Harm reduction is about getting people to stop nicotine." | Its primary aim is fewer smoking-related illnesses and deaths, whether or not nicotine use ends. |
| "Sweden has low smoking because nobody uses nicotine." | Fagerström puts Swedish nicotine use at about 22%; the difference is how it is consumed. |
| "Snus can be bought legally in UK shops." | Supply of tobacco for oral use is prohibited under the 1992 regulations. Tobacco-free pouches are treated differently. |
Using nicotine products responsibly
Everything on Snuzone UK is for adults aged 18 and over. Nicotine is addictive, and the public health argument for pouches applies to people who already smoke or use nicotine, not to anyone who does not. If you have never smoked, the best choice is not to start.
If you already use nicotine, strength is the main thing to get right. Shopping by nicotine strength lets you compare products by nicotine content and pick a level that suits you rather than going straight to the top end. Some users also mix in nicotine-free snus, which keeps the familiar pouch format without any nicotine. If you want to stop smoking altogether, free support is available through NHS stop-smoking services.
