Snus is a moist oral tobacco product that is placed behind the upper lip, either loose or in portioned sachets, which resemble miniature tea bags. It is a smokeless tobacco product that is used by placing it between the upper lip and gum. Snus is a Swedish product that is not fermented and is pasteurized, which inhibits the growth of bacteria. It is a compelling harm reduction alternative to cigarettes and has been used widely by consumers in Sweden over the past four to five decades. Snus contains nicotine, so it is addictive, and quitting this habit has the same unpleasant side effects as when you stop smoking. However, compared to cigarette smoking, the use of snus is probably less harmful. Snus has been found to reduce or eliminate the risk of cancers associated with the use of other tobacco products, such as chewing tobacco and cigarettes. Snus has become a substitute for smoking, particularly among men, and has the potential to deliver enormous harm reduction benefits as demonstrated in Sweden, particularly in reducing the incidence of lung cancer.
