“…The limited research investigating parental heavy drinking has primarily focused on alcohol outcomes and identified associations ranging from earlier initiation into alcohol consumption to increased alcohol dependence in adulthood (Parker & Harford, 1987;Rossow, Keating, Felix, & McCambridge, 2016). For many individuals, heavy drinking is indicative of alcohol misuse (Lloyd & Kepple, 2017). While the concurrent use of opioids and alcohol is an established risk factor for drug overdose (Shah, Lathrop, Reichard, & Landen, 2008), previous research has also indicated that many other potential pathways might exist linking parental heavy drinking with adult non-fatal drug overdoses, including factors such as depressive symptoms, low social support, juvenile delinquency, dysfunctional family environments, and low family cohesion (Bijttebier & Goethals, 2006;Finan, Schulz, Gordon, & Ohannessian, 2015;Pabayo, Alcantara, Kawachi, Wood, & Kerr, 2013;Snyder & Merritt, 2015).…”
