Snus use and smoking behaviors: preliminary findings from a prospective cohort study among US Midwest young adults.

The effect of snus use on smoking behaviors among US young adults is largely unknown. Data from the Minnesota Adolescent Community Cohort Study collected in 2010 to 2011 and 2011 to 2012 (participants aged 20-28 years) showed that young adult nonsmokers who had tried snus were subsequently more likely than those who had not tried snus to become current smokers (n = 1696; adjusted odds ratio = 1.79; 95% confidence interval = 1.01, 3.14). Snus use was not associated with subsequent smoking cessation or reduction among young adult current smokers (n = 488; P > .46).
