“…(Immervoll, 2009;Nelson, 2004;Walker, 2004) Higher income may improve individual health outcomes through its direct influence on material conditions (ability to work, housing, health care access and nutrition) and indirectly by enabling control over life situations. (Deaton, 2002;Marmot, 2004) However, observational studies have found that higher income among PWUD is also associated with high-intensity drug use (Bretteville-Jensen & Sutton, 1996;DeBeck et al, 2007;Deschenes & Anglin, 1991;Grapendaal, Lewu, & Nelen, 1995;Sherman & Latkin, 2002), suggesting a more complex relationship between income and drug use. While this association may be explained in part by the need for individuals with higher intensity drug addiction to generate more income in order to meet their drug use needs (Bourgois, 1998;Deering et al, 2013;Maher, 1997), observational studies also suggest that some income generation strategies can contribute to higher intensity drug use or create additional barriers to decreasing drug use.…”
