Swedish snus is a moist, ground tobacco product placed under the upper lip. Unlike cigarettes, it produces no smoke, and unlike American dipping tobacco, it is heat-treated (pasteurized) rather than fermented, which results in significantly lower levels of certain harmful chemicals. Snus has been used in Sweden since the early 1800s and remains one of the most popular tobacco products in the country, where smoking rates are among the lowest in Europe.
How Snus Is Made
The production process is what sets Swedish snus apart from most other smokeless tobacco. After the tobacco is ground, it undergoes a controlled heat treatment similar to pasteurization in dairy products. This step kills harmful microorganisms and keeps levels of tobacco-specific nitrosamines (TSNAs), a group of cancer-linked chemicals, much lower than what you’d find in fermented products like American moist snuff.
How much lower? Swedish and Northern European snus typically contains TSNA levels in the range of 390 to 4,910 nanograms per gram. Traditional (non-snus) American moist snuff ranges from roughly 3,110 to 52,500 nanograms per gram, often ten times higher. The difference comes down to that pasteurization step replacing the fermentation process used by most American manufacturers.
What’s Inside the Pouch
Tobacco actually makes up less than 40% of the product by weight. The rest is mostly water (45 to 60%), along with salt (1.5 to 3.5%), humectants like propylene glycol or glycerol that keep the product moist (1.5 to 3.5%), sodium bicarbonate (1.2 to 3.5%), and small amounts of flavoring. The sodium bicarbonate serves an important purpose: it raises the pH, which shifts nicotine into a form that absorbs more easily through the tissue of your gums. This is why snus delivers nicotine without needing to be chewed or spit.
Loose Snus vs. Portion Snus
Snus comes in two main forms. Loose snus is a moist, compacted tobacco that users pinch and shape with their fingers before placing it under the upper lip. Portion snus comes pre-packed in small pouches, similar to a tiny tea bag, and is the more convenient and increasingly popular option.
Portion pouches vary in size: mini pouches weigh about 0.4 grams, standard (large) pouches run 0.8 to 1 gram, and maxi pouches range from 1.5 to 2 grams. Moisture content typically falls between 25% and 50% of the product weight, with smaller pouches tending to be drier. You’ll also see white and brown pouches. Brown pouches get their color from an extra water-spray step during manufacturing that stains the pouch material, and they tend to feel wetter in the mouth.
Regardless of format, the vast majority of users (96% of pouch users, 99% of loose users) place the product between the gum and upper lip. About a third of pouch users move the portion around during use, compared to roughly one in five loose users, likely because the pouch shape makes it easier to shift around.
Health Risks Compared to Smoking
Swedish snus is not risk-free, but the evidence suggests it carries substantially lower health risks than cigarettes. In 2019, the U.S. FDA authorized eight General Snus products as “modified risk tobacco products,” allowing the company to state: “Using General Snus instead of cigarettes puts you at a lower risk of mouth cancer, heart disease, lung cancer, stroke, emphysema, and chronic bronchitis.” That designation was based on extensive review of toxicology and epidemiological data.
The oral cancer question is one that comes up frequently. A large meta-analysis examining 38 studies on smokeless tobacco and oral cancer found an overall increased risk with a relative risk of 1.87. But when the data was broken down, no increased risk appeared in Scandinavian studies specifically. When researchers restricted their analysis to the seven studies that properly adjusted for smoking and alcohol use, the excess risk disappeared entirely, landing at a relative risk of 1.02. The elevated risk in the overall analysis was driven largely by older studies conducted before 1980, when manufacturing standards and product composition were different.
Pancreatic cancer has also been studied in relation to snus use, though the data is more limited and less conclusive than for oral cancer.
The GothiaTek Quality Standard
One reason Swedish snus has a different chemical profile than other smokeless tobacco comes down to a voluntary quality standard called GothiaTek, developed by Swedish Match. This standard sets maximum allowable limits for contaminants in finished snus products, including caps of 10 micrograms per gram for arsenic, lead, and cadmium. It also sets limits on TSNAs and other unwanted compounds. While the standard is voluntary and specific to one manufacturer, it has shaped expectations across the Swedish snus industry and influenced how regulators evaluate these products.
Where Snus Is Legal
The European Union banned the sale of snus in 1992, a prohibition that has been carried through multiple directives and remains in effect under the current 2014 Tobacco Products Directive. Sweden, however, negotiated an exemption when it joined the EU in 1995. The exemption was written into Sweden’s Accession Treaty, allowing snus to be manufactured and sold domestically. Norway, as part of the European Economic Area, also permits snus sales.
The catch: Sweden agreed to ensure that snus would not be marketed to consumers in other EU member states, including through online or distance selling. Travelers can bring snus across borders for personal use or as gifts, and duty-free sales are allowed on ships before they reach another EU port, but commercial distribution into other EU countries is prohibited. Despite the ban, snus use has been rising among young people in neighboring countries like Finland, largely through cross-border purchases.
In the United States, snus is legal and available from both Swedish and American manufacturers, though the products differ in composition and manufacturing methods.
Snus vs. Nicotine Pouches
A newer category of products, often called nicotine pouches or “all-white” pouches, looks nearly identical to portion snus but contains no tobacco at all. Brands like ZYN (made by Swedish Match) use nicotine extracted from tobacco, or in some cases synthetic nicotine, combined with plant-based fillers, pH adjusters, stabilizers, and flavorings packed into a cellulose pouch. Because they contain no tobacco leaf, nicotine pouches are classified differently from snus under most regulatory frameworks and are not subject to the EU snus ban. Swedish snus, by contrast, always contains actual ground tobacco as its core ingredient.
