“…For example, childhood maltreatment is commonly perpetrated by disadvantaged parents such as teenage mothers (Thornberry et al, 2014) who disproportionately experience prenatal and postnatal substance use disorders (Smith et al, 2007). In addition, gender (Baiden et al, 2014), poverty (Reinarman, 2011;Slack et al, 2004;Thornberry et al, 2014), poor educational achievement (Slack et al, 2004), and being single/never married (Degenhardt et al, 2008;Messman-Moore et al, 2000) may also be associated with exposure to childhood maltreatment (Baiden et al, 2014;Fluke et al, 2003;Slack et al, 2004;Smith et al, 2007;Thornberry et al, 2014) as well as cannabis use disorders (Choquet et al, 2008;Degenhardt et al, 2008;Horwood et al, 2010;Reinarman, 2011;Wallace et al, 2003). However, few studies have controlled for these potential confounding factors and/or covariates.…”
