“…For example, it has been suggested that externalizing behavior in children may have a negative impact on parent-child communication and bonding (Reed & Dubow, 1997), which in turn has been found to be associated with the later use of illicit drugs by the children (Ledoux, Miller, Choquet, & Plant, 2002). Alternatively, children with a high level of externalizing behavior are more prone to drop out of school and to poor educational attainment (Moffitt & Silva, 1987), which may lead to early substance use (King et al, 2004), and in turn, be associated with CUD in early adulthood.…”
