“…Comparative carcinogenic profiles suggest snus is less harmful than conventional tobacco products (Hatsukami, Lemmonds, Zhang, et al, 2004; Stepanov, Jensen, Hatsukami, & Hecht, 2008), including cigarettes (Lee, 2011; Levy et al, 2006; O’Connor, 2012), but it still carries health risks. The introduction of snus to the US tobacco market has not yet changed the nationwide prevalence of smokeless tobacco use (Agaku et al, 2014; Bhattacharyya, 2012; Biener et al, 2016; Boyle, Saint Claire, Kinney, D’Silva, & Carusi, 2012; Choi & Forster, 2013; Fix et al, 2014; Lee, Hebert, Nonnemaker, & Kim, 2014; Maher, Bushore, Rohde, Dent, & Peterson, 2012; Soneji, Sargent, & Tanski, 2016; Zhu et al, 2013, 2009), but there may exist subgroups of the population who are more receptive to snus than others.…”
