“…However, some studies that have included neighbourhood disadvantage in multivariate models predicting drug use still found a significant effect for neighbourhood when controlling for social resources (Boardman et al, 2001), opinions about friends’ use (Gibbons et al, 2004) or friend’s acceptance of use (Sunder et al, 2007), suggesting that place influences drug use regardless of social network characteristics. For example, one study found that seeing the drug and other people using (Ehrman, Robbins, Childress, & O’Brien, 1992; Epstein et al, 2009) may lead one to use or use more often or that being at a place where the person has used or been exposed to use triggers the desire to get high (Bradizza & Stasiewicz, 2003; Crum et al, 1996).…”
