Snus and Health: The Swiss Guide for Adults

In short: In Switzerland, snus is legally available to adults, but it is not risk-free. The best-documented effects are local changes to the gums and oral mucosa and the effect of nicotine on the heart and circulation. Nicotine is addictive. Pregnant women, people with cardiovascular disease and minors should not use snus.

Snus has become much better known in Switzerland. Yet the health side is often underestimated: what is considered "smoke-free" comes with its own risks that many people are unaware of. This guide sums up what is known about the mouth, gums, cardiovascular system and addiction, which groups of people need to be especially careful and how you, as an adult, can make informed decisions.

Key points

Point	Details
Local damage in the mouth	Snus can cause gum recession and mucosal changes where the pouch sits.
Nicotine	Nicotine raises heart rate and blood pressure and is addictive.
Risk groups	Pregnant or breastfeeding women, people with cardiovascular disease and minors should not use snus.
No smoke, but not risk-free	Snus produces no smoke. That does not make it harmless.
Conscious use	Choose strength, wearing time and frequency consciously and take changes in your mouth seriously.

Effects of snus on the mouth and gums

The snus pouch sits under the upper lip and stays in direct contact with the gums and mucosa for a long time. The effects on the mouth are among the best-documented consequences of snus use.

Pressure and ingredients can cause irritation and inflammation at the application site. Commonly described is gum recession caused by snus (in German), which usually starts where the pouch sits. Possible consequences are exposed tooth necks and teeth that are sensitive to cold or heat.

According to the German association of public health dentists BZÖG (in German), the risk of mucosal changes is linked to how long snus has been used, and loose snus leads to such changes much more often than portion snus in pouches. You can read more about the individual side effects in our article Is snus harmful? Side effects and risks at a glance.

Loose snus and portion snus compared

Feature	Loose snus	Portion snus
Contact with tissue	more direct	contained in the pouch
Mucosal changes	more frequent	less frequent, but possible
Dosing	more difficult	easier and more even

Changes occur mainly at the application site.
Whitish patches on the mucosa can be a warning sign.
If you use snus regularly, tell your dentist and keep up with check-ups.

Tip: Look at your oral mucosa regularly. Have any whitish discolouration or receding gums where the pouch sits checked by a dentist.

Nicotine: effects on the heart and circulation

With snus, nicotine is not inhaled but absorbed into the blood through the oral mucosa. The effect is reliable: according to the AOK (in German), heart rate and blood pressure rise noticeably after use. For people with high blood pressure or cardiovascular disease, this can have relevant consequences.

We explain how different strengths work in the article Understanding nicotine strength. An overview of mg values per pouch can be found under Snus dosage: which strength suits you?.

Typical acute effects of nicotine, especially with too high a dose:

Dizziness and light-headedness
Nausea, sometimes vomiting
Increased heart rate and higher blood pressure
Rapid tolerance and dependence with regular use

What to watch out for:

Do not use on an empty stomach.
Choose a strength that matches your previous nicotine use, and do not start higher.
Limit the wearing time per pouch.
If you feel dizzy or your heart races, remove the pouch immediately.

Snus and cigarettes: what is different

Snus produces no smoke, no tar and no second-hand smoke. That does not mean snus is harmless. Both products contain nicotine, both are addictive, and snus puts direct strain on the gums and oral mucosa.

Criterion	Snus	Cigarettes
Smoke and second-hand smoke	none	yes
Nicotine and addiction	yes	yes
Effect on heart rate	yes	yes
Strain on the mouth	local, at the application site	from smoke, throughout the mouth

You can find a detailed comparison of taste, cost and risks under Snus vs. cigarettes. Important: snus is not a medicine. If you want to stop using nicotine, your GP or an addiction counselling service can support you.

Particular risks for certain groups of people

Nicotine is addictive for everyone. For some groups, however, the consequences are particularly serious.

Pregnant and breastfeeding women should avoid all nicotine products. According to Apotheken Umschau (in German), nicotine during pregnancy is associated with premature birth, low birth weight and malformations such as cleft palate.

People with cardiovascular disease react more strongly to the rise in pulse and blood pressure. With high blood pressure, heart rhythm disorders or coronary heart disease: no nicotine without medical advice.

Minors: the brain keeps developing into early adulthood, and nicotine interferes with this development. In Switzerland, snus and nicotine pouches may only be sold to people aged 18 and over since 1 October 2024.

Non-smokers: if you do not smoke and do not use nicotine, do not start.

Practical tips for adults who use snus

If you are an adult who already uses nicotine and snus, a few habits can help you use it more consciously. That does not make snus risk-free.

Strength: choose a strength that matches your usual consumption. Higher mg values mean more nicotine per pouch.
Placement: place the pouch under your upper lip and change the spot from time to time.
Wearing time: do not keep the pouch in your mouth for hours.
Frequency: keep an eye on the number of pouches per day.
Observation: have any changes to your gums or mucosa checked by a dentist.

Tobacco-free nicotine pouches contain no tobacco, but they do contain nicotine. Long-term data on these products is still largely missing. They are not risk-free either.

Storage and protecting children:

Never leave cans lying around and keep them out of reach of children and pets.
Dispose of used pouches in the lid compartment or a closed container.
If a child has swallowed a pouch or put one in their mouth: call Tox Info Suisse on 145, in an emergency 144.

Why a sober view of snus matters

Public debate often boils down to two extremes: "snus is harmless" or "snus is terrible". Both fall short. Snus carries specific, documented risks for certain parts of the body and certain groups of people. Adults who know these risks and decide consciously are making an informed choice.

There is still hardly any long-term data on tobacco-free nicotine pouches. What a decade of tobacco snus does to the gums is well described. What a decade of nicotine pouches does is still an open question.

Retailers also bear responsibility: label products clearly, enforce the age limit consistently and name the risks openly. At Snustrend, products are sold only to adults aged 18 and over.

Yes. Snus can cause gum recession and mucosal changes at the application site. Loose snus leads to such changes more often than portion snus.

Is snus legal in Switzerland?

Yes. Snus has been legal in Switzerland since 2019. Since 1 October 2024, the Tobacco Products Act applies: snus and nicotine pouches may only be sold to people aged 18 and over, including online.
