Snus is an oral tobacco product that has been used for more than 200 years. Named after the Swedish word for snuff, snus is made from ground tobacco leaves that are mixed with salt and water. It may also contain food-grade tobacco smoke aroma, or other flavorings, and is placed under the upper lip in small teabag-like sachets called portion snus or loose. Snus is most widely used in Scandinavia, particularly in Sweden and Norway, where a form of the product known as ‘Swedish snus’ dominates the market.
