Snus ( SNOOSS, Swedish: [ˈsnʉːs] ) is a tobacco product, originating from a variant of dry snuff in early 18th-century Sweden. It is placed between the upper lip and gum for extended periods, as a form of sublabial administration. Snus is not fermented. Although used similarly to American dipping tobacco, snus does not typically result in the need for spitting and, unlike naswar, snus is steam-pasteurized.

The sale of snus is illegal in several countries, including Australia, New Zealand and all European Union (EU) countries except for Sweden. It is the most common type of tobacco product in Norway, which is not in the EU, and is also available in Switzerland. Some European + EU countries, such as the United Kingdom and Estonia, allow the sale of nicotine pouches, snus-like products that contain nicotine but no tobacco. Snus is also available in the United States. Canada makes it difficult to obtain snus through its high taxes on imported tobacco products.Snus has been seen as an alternative to smoking, vaping, chewing, dipping, and dissolvable and snuff tobacco products. Snus usually contains nicotine, which can lead to nicotine addiction. The chemical constituents of different types of snus vary, and population-level studies suggest that the disease risks vary as well. Using snus is harmful to health, although much less than smoking tobacco.
