“…Consistent with the evidence identifying a complex drug use-income relationship, and given the difficulty of observing drug use, a number of studies have linked monthly SA disbursement to cyclical and substantial increases in the risk of experiencing drug-related harms, including accidental overdose (Otterstatter, Amlani, Guan, Richardson, & Buxton, 2016;Riddell & Riddell, 2006;Verheul, Singer, & Christenson, 1997;Zlotorzynska et al, 2014), hospitalizations (Dobkin & Puller, 2007;Halpern & Mechem, 2001;Maynard C, 2000), drug-induced psychiatric emergency department visits (Catalano & McConnell, 1999;Pickett T, 2015), HIV and substance abuse treatment interruption (Anis et al, 2002;Chan et al, 2004;Svikis, Pickens, Schweitzer, Johnson, & Haug, 1999), and related burdens on health, social and police services (Brunette, Kominsky, & Ruiz, 1991;Li et al, 2007;Pickett T, 2015;Riddell & Riddell, 2006;Shaner et al, 1995;Verheul et al, 1997;Zlotorzynska et al, 2014). While the aforementioned studies used predominantly administrative data, studies examining the drug use-income relationship that directly account for drug use are rare.…”
