Is snus harmful? Snus is enjoying growing popularity not only worldwide but also in the United Kingdom – often as a supposedly harmless alternative to cigarettes. But is snus really harmless, or does it harbour hidden risks? The answer is complex: although snus does not contain any combustion products as smoking does, it does contain nicotine and carcinogenic nitrosamines. These can lead to addiction and a number of diseases. In this article, you will learn about the dangers of snus, how it compares to cigarettes, the possible long-term effects and the legal framework in the United Kingdom. We will also discuss whether snus can help you quit smoking – and what you should definitely consider before consuming it.
What exactly is snus?
Snus is a smokeless tobacco product that originated in Sweden, where it has been consumed for centuries. It consists of ground tobacco, water, salt and flavourings, which are heated in a pasteurisation process. Unlike chewing tobacco, snus is not chewed but placed under the upper lip, where nicotine and flavourings are absorbed through the mucous membrane of the mouth. There are two main types: loose snus, where the amount is portioned individually, and portion snus, where small pouches are pre-made. Both types are available in different strengths and flavours. The range extends from mild tobacco varieties to fresh mint flavours and fruity varieties. Thanks to its variety and discreet use, snus is becoming increasingly popular – even in countries with strict smoking bans.
Is snus harmful to health? A look at the facts
Many users turn to snus in the belief that it is significantly less harmful than cigarettes. In fact, the risks associated with combustion gases such as tar and carbon monoxide are eliminated. Nevertheless, snus contains substances that are harmful to health. Nicotine is highly addictive and can increase heart rate and blood pressure. Carcinogenic nitrosamines in tobacco increase the risk of mouth, throat and pancreatic cancer. Studies, including those conducted by the Karolinska Institutet, also show a link to cardiovascular disease. Even though the relative risk is lower than that of cigarettes, this does not mean that snus is harmless. Health experts emphasise that any form of tobacco consumption is potentially harmful – and that the best way to avoid risk is to abstain.
Overview of side effects and risks
The consumption of snus can have both short-term and long-term side effects. Acute effects include increased heart rate, dizziness, nausea and dry mouth – especially for beginners or those with high nicotine content. In the long term, gum recession, tooth loss and chronic inflammation in the oral cavity can occur. Constant nicotine intake puts strain on the cardiovascular system and increases the risk of high blood pressure, heart attacks and strokes. There is also the risk of psychological and physical dependence. Even though snus does not cause smoke damage to the lungs, the consequences for teeth, gums and heart health should not be underestimated. Anyone who uses snus should be aware of these risks and critically question their use.
Snus vs. cigarettes – comparing the harmfulness
When comparing snus with cigarettes, there are clear differences: cigarettes release over 7,000 chemicals when smoked, including many highly toxic substances. Snus does not involve combustion, which means that these substances are not produced. Studies show that snus carries a lower risk of lung cancer. However, the risk of cancer in the mouth and digestive tract remains. In addition, snus, like cigarettes, can lead to severe nicotine addiction. For smokers who switch completely to snus, the risk may be reduced, but it is still not healthy. The WHO also classifies smokeless tobacco as harmful to health. Those who want to quit tobacco consumption altogether should opt for nicotine-free alternatives.
Can snus help you quit smoking?
Some see snus as an aid to quitting smoking because it delivers nicotine without smoke. In fact, there is evidence that smokers in Sweden are more likely to quit smoking with snus than without it. But this strategy has its pitfalls: although exposure to smoke toxins is reduced, nicotine addiction remains. Many users do not switch completely, but consume both in parallel. Professional associations such as German Cancer Aid warn that switching to snus is not the same as quitting smoking. Scientifically proven methods such as nicotine replacement products, behavioural therapy or medical support are more suitable.
Long-term effects of regular snus consumption
Long-term snus use can have serious health consequences. In addition to an increased risk of cancer in the mouth and throat area, the cardiovascular system can also be permanently damaged. Gum disease, tooth loss and chronic inflammation are among the most common side effects. Studies suggest that snus can permanently increase blood pressure, which increases the risk of heart attacks. In addition, it can be highly addictive, making it difficult to quit. Although the damage is often less dramatic than that caused by smoking, it adds up over the years to pose a significant health risk.
Legal situation in Germany and the EU
In Germany, the sale of snus is prohibited under a 1992 EU tobacco directive – with the exception of Sweden, which has a special permit. However, private individuals are allowed to import small quantities from Sweden for their own use. Online orders from non-EU countries are subject to customs and import regulations. Snus is legally available in Norway and Switzerland, but strictly prohibited in many other countries. Anyone wishing to import snus should be sure to check the current laws in the destination country to avoid fines or penalties. You can find out more about the legal aspects in the article.

Social perception of snus
In Sweden and Norway, snus is considered a common alternative to cigarettes, partly because of the lower rates of smoking-related diseases. In Germany, however, it is less widespread, mainly due to the ban on its sale. Critics see snus as a gateway to nicotine addiction, while proponents argue that it poses less risk than smoking. The debate is also reflected in legislation: while some countries allow snus, others enforce strict bans. The image of snus therefore remains culturally influenced and heavily dependent on the health policy context.
Scientific findings and studies
Research on snus is extensive but not complete. According to an evaluation by the US National Cancer Institute, snus may increase the risk of oral cancer, pancreatic cancer and cardiovascular disease. The Karolinska Institutet in Stockholm points out that the lower risks compared to cigarettes do not mean that snus is harmless. At the same time, data shows that the prevalence of snus in Sweden is associated with a lower smoking rate. These contradictory findings mean that snus continues to be the subject of controversy – both in science and in politics.
Conclusion – How harmful is snus really?
Snus is less harmful than cigarettes, but by no means harmless. It contains nicotine, which is addictive, and carcinogenic nitrosamines, which can cause serious illnesses. For smokers, switching to snus can reduce certain risks, but it is not a substitute for quitting nicotine consumption altogether. Anyone who wants to protect their health should give up tobacco and nicotine completely in the long term. Those who still decide to use snus should be aware of the risks, look for high-quality products and keep their consumption to a minimum.

Why is snus not good?
Because it contains carcinogenic substances and nicotine, which can lead to addiction and illness. The risk is lower than with smoking, but by no means zero.
