Yes, the title is spelled correctly! Snus is moist, oral snuff originating in Sweden that is now being promoted by big USA tobacco manufacturers.
Research has found that those who use snus exclusively, or who use snus and cigarettes, report significantly higher dependence on nicotine than those who only smoke cigarettes. People who use both reported the toughest withdrawal symptoms.
PositiveTip: Smokeless tobacco products, while appealing, are associated with cancers of the mouth, esophagus and pancreas. Just say no!
