Is Snus Bad For You? Let’s Talk About What You Are Actually Using

  • By Simon Crafts

Published: January 2025

The phrase “snus is bad for you” gets thrown around far too casually for something most people cannot even define properly. In the UK right now, walk into any convenience store and ask for snus and you will be handed a nicotine pouch. Ten years ago, that would have meant a tobacco product imported from Sweden and likely stuck in customs for three weeks. The name stayed the same, but the product changed underneath it. That is where most of the confusion begins. If we are going to discuss health properly, we need to start with what is actually sitting under your lip today, not what sat under someone’s lip in Stockholm in 1998.

 

Snus Is No Longer One Product and That Changes Everything

There was a period where snus meant Swedish tobacco. Simple as that. It was pasteurised, portioned, and regulated tightly across Europe. Outside Sweden, it became something people ordered online and hoped would slip past border checks without attracting a tax bill that cost more than the cans themselves. That friction is part of the category’s history and it matters because it shaped what came next. When nicotine pouches appeared, they did not try to reinvent the format. They copied it almost perfectly. Same size, same placement, same discreet use, but no tobacco leaf inside.

 

That removal of tobacco leaf is not cosmetic. It strips out thousands of naturally occurring plant compounds that come with tobacco. The pouch still delivers nicotine, which is why people use it, but the chemistry is different. The issue now is that most conversations still treat them as identical. A study on tobacco snus gets quoted in a discussion about nicotine pouches and suddenly the lines blur. The name snus became a blanket term, but the ingredients underneath it are no longer uniform. If the foundation of the debate is wrong, the conclusion will be too.

 

The Problem Was Never Just Nicotine

For years nicotine carried the blame for everything associated with smoking, as though it was the sole architect of lung cancer statistics and hospital waiting lists. It is an easy villain because it is the addictive part, the hook that keeps people coming back. But addiction and disease are not the same mechanism. The real damage from cigarettes has always come from burning tobacco and inhaling what that combustion produces. Tar does not materialise out of thin air. Carbon monoxide is not a minor footnote. When something is set on fire and drawn into the lungs thousands of times over decades, the outcome should not surprise anyone. Nicotine keeps the habit alive, but it is not what blackens lung tissue.

 

This is not a fringe argument whispered by pouch retailers trying to defend their corner. The Royal College of Physicians has openly stated that people smoke for nicotine but suffer from the toxic products of combustion. Their harm reduction report remains publicly available here. That distinction has been clear within medical circles for years. It simply does not make for dramatic headlines, and headlines are what most people remember. The chemistry has always been more boring and far more specific than the outrage suggests.

 

Once combustion is removed, the scale of risk shifts whether people like that idea or not. Traditional snus removed smoke but kept tobacco leaf in play. Nicotine pouches remove both. That progression matters. You can argue about dependency, you can argue about overuse, but comparing a tobacco free pouch to a burning cigarette ignores the most obvious variable in the room. Health debates often collapse into extremes because extremes are easier to digest. The reality is more technical than that, and far less theatrical.

 

Smoking vs Traditional Snus vs Nicotine Pouches

Let’s stop pretending all nicotine products sit on the same shelf of risk, because they simply do not. A cigarette works by burning tobacco and dragging that smoke straight into the lungs. That means heat, tar, carbon monoxide, and a long list of byproducts entering tissue that is designed to exchange oxygen, not process fire. The nicotine hits fast, which is exactly why cigarettes are so gripping, but it does not arrive alone. It arrives with everything combustion produces. That is not dramatic language, that is basic mechanics. Lungs are delicate. They are not built for decades of smoke exposure, no matter how nostalgic the ritual might feel.

 

Traditional snus removes the smoke entirely and shifts nicotine delivery to the buccal mucosa, the lining of the gum under the upper lip. Nothing is inhaled. Nothing passes through lung tissue. Tobacco leaf is still present, so it is not chemically stripped back, but the biggest driver of smoking related disease is gone the moment combustion leaves the equation. The experience is different too. The nicotine curve is steadier, less frantic, and the whole act is quieter. For many long term smokers in Sweden, that shift alone was enough to break the cigarette cycle without losing nicotine altogether.

 

Nicotine pouches go further by removing tobacco leaf as well. The delivery route stays the same, through the gum, but the plant material disappears. No smoke, no tar, no leaf. From a user perspective, that comparison is not complicated. One method repeatedly fills the lungs with combustion byproducts. The other sits discreetly under the lip and absorbs through tissue that handles food and drink every single day. That does not make nicotine pouches virtuous, but when comparing routes of exposure, it is difficult to argue that lungs and fire were ever going to win that contest.

 

Does Snus Cause Cancer or Are We Asking the Wrong Question

When someone says “snus causes cancer”, it usually lands as if the case is closed. But closed based on what exactly? Cigarettes cause lung cancer because smoke is inhaled into lung tissue repeatedly over years. That mechanism is not mysterious. Fire plus lungs is rarely going to end well. Traditional snus does not involve inhalation at all. The tobacco sits under the lip, nicotine absorbs through the gum, and the lungs are not part of the process. That alone forces the comparison to slow down. It does not mean tobacco snus is flawless, but it means the pathway that made cigarettes catastrophic simply is not there.

 

Then nicotine pouches enter the picture and things get even more awkward for the headline version of the argument. No tobacco leaf. No combustion. Just nicotine and filler sitting under the lip. If nicotine itself were driving cancer in the way people imply, every nicotine replacement therapy product on pharmacy shelves would carry the same fear narrative. They do not, because the chemistry does not support it. Cancer Research UK separates nicotine from the harmful compounds in tobacco smoke for that reason. Their breakdown is here. The leap from “contains nicotine” to “causes cancer” skips the mechanism entirely.

 

Sweden tends to surface in this debate because it complicates the simple story. Smoking rates dropped dramatically while oral nicotine use remained culturally normal. Lung cancer rates reflect that behavioural shift. That is not marketing spin, it is population data. If every nicotine format carried the same cancer burden as cigarettes, Sweden would not look the way it does statistically. That does not crown snus as a health product. It simply underlines a point that is often ignored. Removing smoke and removing tobacco leaf changes the exposure profile. Whether someone likes nicotine or not does not alter that basic reality.

Is Nicotine Itself Dangerous or Just Conveniently Blamed

Nicotine tends to get treated like the mastermind behind every smoking statistic, mainly because it is the addictive part and addiction makes people uncomfortable. But if nicotine on its own were as destructive as it is often portrayed, we would see that damage reflected in every controlled nicotine format available. We do not. What nicotine actually does is stimulate. It raises heart rate slightly. It sharpens focus for many users. That is not an endorsement, it is just how the compound behaves. The real devastation tied to cigarettes came from years of smoke entering lung tissue, not from a stimulant sitting quietly in the bloodstream. Those are two very different things, even if they get spoken about as one.

 

Dr Huberman has even touched on this without turning it into a morality play. He has spoken about nicotine improving focus and attention when used deliberately, while also making it clear that dependency is a real risk if you are careless. That balance is usually what gets ignored. He is not out there claiming nicotine pouches are health food, and he is certainly not pretending cigarettes and oral nicotine are the same thing either. The delivery route matters. Smoke behaves differently in the body than something absorbed through the gum, and acting as though that distinction is irrelevant feels more emotional than scientific.

 

None of this is an argument to start using nicotine if you never have. It can form habits quickly. It can nudge cardiovascular markers upward in the short term. But framing it as the singular cause of tobacco related disease misses the part where tobacco was burned and inhaled for decades. Nicotine kept people attached to the behaviour. The behaviour itself, smoke into lungs, did the structural damage. Once you separate those roles, the conversation becomes less dramatic and a lot more grounded in how exposure actually works.

 

Addiction Is the Real Conversation

If there is a serious argument to be had around nicotine pouches, it is not about lungs filling with smoke, it is about dependency. Nicotine is habit forming. That is not controversial and pretending otherwise weakens the entire discussion. What does matter, though, is how addiction develops and how strongly it reinforces behaviour depending on delivery speed. A cigarette delivers nicotine to the brain in seconds. That rapid spike creates a tight feedback loop between action and reward. Light, inhale, relief. Repeat. The speed is part of the grip. Slow that delivery down and the loop changes shape.

 

Oral nicotine behaves differently. Absorption through the gum is slower and steadier. There is no dramatic spike within seconds, which means the reinforcement pattern is not identical to smoking. That does not mean someone cannot become dependent on pouches. They can, especially at higher strengths or with constant use. But the mechanism is less frantic. The ritual is quieter. There is no step outside every forty five minutes to stand in the cold because the lungs are demanding another hit of smoke.

 

Sweden Is Not an Accident

Sweden always enters this conversation eventually, usually dismissed with a shrug as some cultural anomaly that does not apply elsewhere. But population trends are rarely accidental at scale. Sweden has one of the lowest smoking rates in Europe while maintaining widespread use of oral nicotine products. That shift did not happen quietly and it did not happen overnight. Cigarettes declined. Oral formats remained socially acceptable. Lung cancer rates among men reflect that change over time. If nicotine in every form carried the same risk profile as inhaled tobacco, those numbers would not separate the way they do.

 

This is not about presenting Sweden as a utopia or pretending traditional snus is harmless. Tobacco leaf still exists in that format. What Sweden demonstrates, however, is substitution. When smokers are given a socially viable alternative that removes combustion, behaviour changes. That change compounds over decades. The European Commission’s smoking data consistently shows Sweden below EU averages, which is not a coincidence. You can review the broader overview here. Patterns at that scale deserve attention rather than dismissal.

 

Nicotine pouches extend that substitution model even further by removing tobacco leaf as well. Whether someone personally supports nicotine use is a separate moral discussion. The public health pattern remains clear. When smoke leaves the equation, the long term outlook shifts. Sweden is not proof that nicotine is harmless. It is proof that combustion was the real problem all along.

 

So, Is Snus Bad For You

If by snus someone means cigarettes, then the damage is already well understood and has been for decades. If they mean the traditional tobacco portions under the lip, the picture changes because smoke leaves the equation, even though tobacco does not. And if they are talking about the nicotine pouches sold in UK supermarkets today, then we are in a different category again. No smoke moving through lung tissue. No tar building up over time. No tobacco leaf sitting in the pouch. The label might be the same, but what the body is actually exposed to is not. Grouping all of that together might sound firm and decisive, yet it skips over the basic mechanics of how each product is used and where it actually goes once it enters the body.

 

Nicotine itself is not harmless. It forms habits. It can elevate heart rate. It is not something to introduce casually if you have never used it. But pretending it carries the same structural damage as years of inhaling burnt tobacco oversimplifies what caused the original crisis. Smoke destroyed lungs. Combustion created carcinogens. Nicotine reinforced behaviour. Those roles are not interchangeable. Once separated, the argument becomes less about outrage and more about mechanics.

 

If someone does not use nicotine, there is no benefit in starting. That remains straightforward. For someone already consuming it, especially through cigarettes, the method of delivery is not a minor detail. Lungs and fire were always the losing combination. Buccal absorption without tobacco leaf is a different category entirely. Whether that difference is acknowledged or not does not change the chemistry behind it.
