“…While drug-driving in general appears to be a relatively common occurrence among college students (e.g., Davey, Davey, & Obst, 2005; Kohn, Saleheen, Borrup, Rogers, & Lapidus, 2014) and those who go out to experience nightlife and late-night parties (e.g., Calafat et al, 2009; Degenhardt, Dillon, Duff, & Ross, 2006; Duff & Rowland, 2006), DUIC drivers in particular are often young, male, and seem likely to report frequent cannabis use and polysubstance use (cf. Cook, Shank, Bruno, Turner, & Mann, 2017; Fischer, Rodopoulos, Rehm, & Ivsins, 2006; Jones, Swift, Donnelly, & Weatherburn, 2007; Kelly, Darke, & Ross, 2004; McCarthy, Lynch, & Pederson, 2007; Walsh & Mann, 1999; Whitehill, Rivara, & Moreno, 2014). Safety and legal risk perceptions appear to influence willingness to engage in DUIC.…”
