“…Based on social ecological and resiliency theories (Bronfrenbrenner, 1998; Garmezy, 1991; Rutter, 1987; Stokols et al, 1996), marijuana use during adolescence and emerging adulthood is associated with evolving interactions between individual and social risk and promotive factors that can decrease or accelerate problem trajectories (Abadi et al, 2011; Bernstein et al, 2011; Brown et al, 2008; Cadoret et al, 1995; Cleveland and Wiebe, 2008; Fowler et al, 2007; Henry and Thornberry, 2010; Hussong et al, 2008; Mrug et al, 2010; Wagner, 2008; Windle et al, 2008; Zucker et al, 2000; Zucker et al, 2008). For example, violence is associated with substance use, particularly among those residing in socio-economically disadvantaged communities (Goldstick et al, 2015; Goldstick et al, 2016; Walton et al, 2009; White et al, 2009), likely due to shared risk and promotive factors for some substances (e.g., marijuana), and/or acute pharmacological effects of substances (e.g., alcohol) (Chermack and Giancola, 1997; White et al, 2009).…”
