“…Several recent studies have found smoke-free campus policies to be associated with reductions in campus smoking prevalence, secondhand smoke exposure, and student perceptions of peer smoking prevalence, as well as an increase in social norms favoring smoke-free environments (Lechner et al, 2012;Lee et al, 2013;Seo et al, 2011). However, considerable challenges in policy implementation have also been identified, including enforcement difficulties, displacement of smokers to the outskirts of campus, community relations, and safety concerns, among other issues (Baillie et al, 2009(Baillie et al, , 2011Fennell, 2012;Procter-Scherdtel and Collins, 2013a;Russette et al, 2014).…”
