Snuff: how to use it, is it harmful and is it legal

Snuff is tobacco inhaled through the nose, legal in Poland for adults, unlike snus, and it is not harmless: IARC classifies smokeless tobacco as Group 1. It is also the oldest known form of tobacco in Europe and the only one that is used through the nose (Sapundzhiev and Werner, The Journal of Laryngology and Otology, 2003). Smokeless tobacco is a much larger phenomenon worldwide than its niche status in Poland suggests: over 300 million people use it in 127 countries (Siddiqi et al., BMC Medicine, 2020). This article explains what snuff is, how to use it, what the literature says about its health effects, and why Polish law treats it differently than snus. Without embellishments, but also without scaring with things that research has not shown, because in this topic exaggeration in one direction is as common as in the other.

KEY INFORMATION
• Smokeless tobacco is used by over 300 million people in 127 countries, and in 2017 it accounted for at least 2.5 million years of life adjusted for disability and 90,791 deaths from cancers of the oral cavity, pharynx, and esophagus (Siddiqi et al., BMC Medicine, 2020).
• IARC classifies smokeless tobacco as a Group 1 carcinogen, meaning it has confirmed carcinogenic effects in humans (Warnakulasuriya, Indian Journal of Medical Research, 2018).
• The absorption rate of nicotine from nasal snuff is similar to smoking, and chronic use leads to morphological and functional changes in the nasal mucosa (Sapundzhiev and Werner, 2003).
• Snus, or oral tobacco, is banned in Poland (Article 7 paragraph 1 of the Act, Journal of Laws 2024 item 1162).
• Snuff is a separate category of “nasal tobacco” in the same law, and its availability to persons under 18 years of age is prohibited.

What is snuff and where did it come from?

It is finely ground, dried tobacco intended for inhalation through the nose. Polish law directly refers to it as nasal tobacco and defines it as a smokeless tobacco product that can be used through the nose. The overarching category, smokeless tobacco product, includes everything that does not involve a combustion process.

The European history of this raw material begins in the second half of the 16th century and looks different than it is usually told. Around 1560, the French ambassador in Lisbon received tobacco, cultivated it, and used it for skin ailments. When he heard about two ladies in France with cancers that could not be cured, he sent the herb to King Francis II, the Queen Mother, and many courtiers (Charlton, Journal of the Royal Society of Medicine, 2004). The genus name of the plant comes from the surname of this ambassador, Jean Nicot, and indirectly also the word nicotine.

It is worth noting that at that time, the herb sent was used externally, not the powder for inhalation. More about the subsequent stages of this history is written in the post about the history of snuff.

How is snuff used and how quickly does nicotine act?

What is felt during this? First, a strong sneeze or burning in the nose, as the powder mechanically irritates the mucous membrane, and then a brief stimulation with a characteristic sharpening of attention. This is the action of nicotine, the same as in cigarettes, only absorbed through the nose instead of the lungs. The effect is shorter and weaker than after inhaling a cigarette, and in a person unaccustomed to it, it often ends in dizziness and nausea rather than pleasure.

Snuff does not help with anything and is not a medicine. It is sometimes described as a way to clear the nose, but that is a result of irritation and mucus secretion, not a therapeutic effect.

A pinch of dry snuff is placed on the back of the hand, most often in the hollow between the thumb and index finger, the hand is brought close to the nose, and one calm breath is taken through one nostril. The other nostril remains free. Excess powder can be gently blown into a tissue. The inhalation should be calm, not abrupt: too strong a pull draws the powder deeper than necessary and irritates the throat.

The speed of action is what distinguishes snuff from oral forms of nicotine. A review dedicated solely to nasal snuff states that the absorption rate of nicotine is similar to that of smoking, and for this reason, the authors once considered it as a possible form of replacement therapy (Sapundzhiev and Werner, The Journal of Laryngology and Otology, 2003).

The noticeable effect appears within a few minutes and depends on the nicotine content in the specific product and the user’s tolerance. People who have not previously had contact with nicotine may feel dizziness or nausea after the first use. Those looking for tobacco-free forms can find a comparison in a separate post about what to smoke instead of tobacco.

Is snuff less harmful than cigarettes?

It is less harmful in some respects and not safe in any. The absence of combustion eliminates smoke and combustion products, but it does not remove either nicotine or carcinogens present in the tobacco itself. Smokeless tobacco was evaluated by four IARC working groups from 1984 to 2009 and concluded that the evidence of its carcinogenicity in humans and experimental animals is sufficient, which led to its classification as Group 1 (Warnakulasuriya, Indian Journal of Medical Research, 2018). The monograph itself was published as volume 89 of this series (IARC Monographs, 2007).

However, it is necessary to indicate which cancers this concerns, as popular descriptions usually miss the literature. The evidence primarily relates to the oral cavity, and for the esophagus and pancreas, the odds ratio was 1.8 and 1.6, respectively, with data mainly coming from American and Nordic studies. For nasal snuff itself, the picture is more cautious: a review dedicated to this one form states that it contains potentially carcinogenic substances, but strong evidence linking its use to a higher occurrence of head and neck cancers has not yet been gathered.

Where does the risk come from in the absence of smoke? The main source is nitrosamines specific to tobacco, described as the strongest and most abundant carcinogens in chewing tobacco and snuff. The best-documented of these are NNN and NNK, and their concentrations vary dramatically between products: in a comparison of Indian and Swedish products, the NNN content was 22.9 versus 0.345 micrograms per gram.

What happens to the nasal mucosa?

This is precisely the effect of snuff that is best documented and at the same time least mentioned. Chronic abuse of nasal snuff leads to morphological and functional changes in the nasal mucosa. This is not about carcinogenesis, but about the tissue through which the substance passes several or a dozen times a day. A functional change means that the nose stops doing what it did before, regardless of how it looks under a microscope.

The same review notes an important comparative point: the risk of cardiovascular diseases is lower in people using snuff than in smokers (Sapundzhiev and Werner, The Journal of Laryngology and Otology, 2003). Thus, it is a different risk profile, not a smaller profile in every dimension.

It is worth naming this difference directly, as the question about snuff usually arises in the context of looking for something less harmful than cigarettes. An honest answer is: some threats disappear with the smoke, some remain, and a new one arises, located in the nose. The comparison is therefore between worse and bad, not between bad and safe.

Does snuff cause addiction like cigarettes?

The mechanism of addiction is the same regardless of the route of administration, and a review dedicated to snuff states directly that the nicotine contained in it leads to dependence. Nicotine binds to nicotinic cholinergic receptors and facilitates the release of neurotransmitters. For the development of addiction itself, the release of dopamine, glutamate, and gamma-aminobutyric acid is particularly important, and withdrawal symptoms are likely due to corticotropin-releasing hormone.

The tendency to nicotine addiction is largely hereditary, and its metabolism rate, mainly dependent on the CYP2A6 enzyme, affects susceptibility to addiction and response to withdrawal treatment (Benowitz, Annual Review of Pharmacology and Toxicology, 2009). The absence of smoke does not change anything in this chain.

Is quitting therefore easier? There is no reason to believe so. Among pharmacological methods with confirmed use, nicotine replacement therapy and bupropion are mentioned. Varenicline, a selective partial agonist of the nicotinic receptor, is mentioned separately. The choice is up to the doctor or pharmacist. The issue of addiction to a substance from a completely different group is discussed in a separate post about whether CBD causes addiction.

What does Polish law say about snuff and snus?

It treats them completely differently, and this is probably the most commonly misunderstood thing in this topic. The Act on the Protection of Health Against the Consequences of Tobacco Use and Tobacco Products, in the consolidated text from 2024, defines nasal tobacco and oral tobacco separately, and then only the latter is subject to a ban.

Article 7 paragraph 1 states that the production and marketing of tobacco for oral use is prohibited. Snus falls exactly under this definition, so its sale in Poland is prohibited, not, as is often written, allowed for adults. Snuff, on the other hand, is nasal tobacco, which is a separate category not covered by this ban (Journal of Laws 2024 item 1162).

The common aspect for both remains the protection of minors: Article 6 paragraph 1 prohibits the availability of tobacco products, electronic cigarettes, and refill containers to persons under 18 years of age. A separate issue is pouches that do not contain tobacco at all, even though they are sometimes sold under a name referring to snus. They are not tobacco products under this law, so the ban described above does not apply to them.

Another way to escape from cigarettes is herbal products without nicotine. Are they safe? We check in the text about herbal cigarettes.

How to store snuff so it doesn’t dry out?

Dry snuff loses its aroma and begins to crumble when the environment is too dry, so it comes down to the tightness of the container and stable humidity. Keep the container at room temperature, away from sunlight and heat sources, and open it only momentarily for use.

Humidity can be most easily stabilized by a two-way regulator, which is a sachet that releases moisture when dry and absorbs it when in excess. Regulators are sold calibrated to a constant value, and the most common calibration is 62%. The sachet works for several weeks, after which it hardens and needs to be replaced. The advantage of constant calibration is that the regulator will not over-moisten the powder even if left for a longer time, as it starts to absorb moisture above the set value.

A hygrometer built into the lid of the container allows checking whether the system actually maintains the set level, instead of guessing by the appearance and smell of the powder. The same solution is used for storing herbal material, so the containers and sachets are the same for both applications. Airtight, odorless containers and humidity regulators can be found in the storage category.

Frequently Asked Questions

What is snuff?

It is finely ground, dried tobacco inhaled through the nose, the oldest known form of tobacco in Europe. Polish law refers to it as nasal tobacco and defines it as a smokeless tobacco product that can be used through the nose. It does not involve a combustion process, so no smoke is produced.

Is snuff the same as snus?

No. Snuff is dry tobacco for inhalation through the nose, while snus is moist oral tobacco placed under the lip. Polish law treats them as two separate categories, and only snus is subject to a ban: Article 7 paragraph 1 prohibits the production and marketing of tobacco for oral use.

How to properly use snuff?

A pinch is placed on the back of the hand, in the hollow between the thumb and index finger, and inhaled with a calm breath through one nostril. Excess can be gently blown out. People without prior contact with nicotine should be cautious due to possible dizziness and nausea.

Is snuff less harmful than cigarettes?

The absence of combustion eliminates smoke, and the cardiovascular risk is lower than that of smokers. However, IARC classifies smokeless tobacco as a Group 1 carcinogen, and chronic use of snuff leads to morphological and functional changes in the nasal mucosa. It is a different risk profile, not a lack of risk.

Does snuff cause addiction?

Yes. The nicotine contained in it leads to dependence, and the absorption rate from the nasal mucosa is similar to that of smoking. The mechanism is the same regardless of the form of the product: nicotine acts on nicotinic cholinergic receptors and influences dopamine release in the reward system.

How to store snuff?

In a tightly closed container, at room temperature, away from sunlight and heat sources. Humidity is stabilized by a two-way regulator in the form of a sachet, sold with a constant calibration, most often at 62%. The sachet works for several weeks, and a hygrometer in the lid allows checking the actual humidity level.
