Snus (pronounced /ˈsnʉːs/) is a moist powder tobacco product that is consumed by placing it under the upper lip for extended periods of time. It was originally developed from powdered snuff that was inhaled through the nostrils. Snus is manufactured and consumed primarily in Sweden and Norway. A version has recently been introduced into the United States and is being test-marketed by two major American tobacco companies as well as one Swedish company. However, the health effects of these new versions of snus have not yet been studied.
