“…Participants commonly reported that SEIs established situations and spaces that enabled reductions in risk behaviours, such as “rushed injections” (Kerr et al, 2007; Small et al, 2012a) and syringe sharing (Fast et al, 2008; Ngo et al, 2009; Parker et al, 2012; Power et al, 2005; Spittal et al, 2004). Accordingly, these interventions were felt to increase control over the injection process (e.g., access to injecting equipment, space to inject) and minimized the impact of social, structural, and spatial barriers to safer injecting (Fairbairn et al, 2008; Kerr et al, 2007; Krusi et al, 2009; McLean, 2012; Ngo et al, 2009; Parker et al, 2012).…”
