“…To my knowledge, this is the first study to provide empirical evidence on the effectiveness of a smoke-free patio policy of bars and restaurants on SHS exposure. The current findings represent a unique and timely contribution to the literature, especially as public support for this policy grows and policy makers in numerous jurisdictions are considering adopting this policy (Thomson et al, 2009). The results of this study are consistent with the extant literature showing that smoke-free legislation is beneficial to health, in part due to a reduction in SHS exposure (e.g., e.g., Hahn et al, 2008;Fowkes et al, 2008;Nagelhout et al, 2011;Millett et al, 2013;Naiman et al, 2010).…”
