“…As of July 2020, at least 2,511 United States and Tribal universities declared smoke‐free and/or tobacco‐free policies, 2,076 (83%) of which placed additional bans on noncombustible product substitutes (e.g., electronic cigarettes; American Nonsmokers' Rights Foundations, 2022; Wang et al, 2018). Campus tobacco‐policy research explores barriers and facilitators of policy implementation (e.g., Hellesen et al, 2022; Lee et al, 2015), acceptance of policies by the general public (e.g., Braverman et al, 2021; Mamudu et al, 2012; Pignataro & Daramola, 2020), and methods for measuring policy compliance (e.g., Fallin et al, 2014; Russette et al, 2014). Relatively few studies have objectively measured behavior change following tobacco policy enactment, and only a small sample of the reports describe efforts to observe smoking directly (e.g., Fitzpatrick et al 2009; Gatto et al, 2019; Harris et al, 2010).…”
