“…Another well-established environmental risk factor is media exposure. A number of cross-sectional (Sargent et al, 2001; Sargent et al, 2005; Hanewinkel & Sargent, 2007), longitudinal (Dalton et al, 2003; Hanewinkel & Sargent, 2008; Jackson, Brown, & L’Engle, 2007; Tanski, Stoolmiller, Gerrard, & Sargent, 2012), and experimental studies (Gibson & Maurer, 2000; Hanewinkel, 2009; Hines, Saris, & Throckmorton-Belzer, 2000; Pechmann & Shih, 1999; Lochbuehler, Kleinjan, & Engels, 2013) have found an association between seeing smoking imagery in movies and own smoking among adolescents.
