| Summary: | Background: Growing awareness of the role social, structural, and environmental factors in producing harm among people who inject drugs (IDU) has underscored the need for safer environment interventions. However, emerging evidence underscores how current interventions are insufficient to bring about more significant reductions in drug-related harm. To date, there have been few studies examining how contextual forces operating within the wider risk environment shape the socio-spatial relations of IDU in relation to safer environment interventions and health care settings. This dissertation seeks to address this gap by examining the socio-spatial dynamics within three settings in Vancouver, Canada: the street-based drug scene; an ‘unsanctioned’ supervised drug consumption room (DCR); and, hospitals.
Methods: This dissertation used an ethno-epidemiological approach, and the individual studies were undertaken in connection with ongoing prospective cohort studies of current and former drug users. Ethnographic fieldwork, including participant-observation, in-depth interviews and qualitative mapping exercises, sought to characterize the socio-spatial relations of IDU in relation to the abovementioned settings.
Results: Study findings underscored how contextual forces shaped the socio-spatial relations of IDU, and thus access to and engagement with safer environment interventions and hospital settings. First, findings highlighted the role of gendered power relations within the street-based drug scene in shaping the spatial practices of highly vulnerable IDU, and constraining their access to a supervised injection facility. Second, findings demonstrated how, by permitting assisted injections, the DCR created a ‘legitimate place’ for IDU who require help injecting, and enabled them to enact risk reduction. Finally, social (e.g., stigmatization) and structural (e.g., abstinence-based drug policies) factors within hospital settings were found to produce considerable suffering (e.g., inadequate pain management) and contribute to discharges from hospital against medical advice.
Conclusions: The collective findings of this dissertation demonstrate how the socio-spatial relations of IDU, and the contextual forces that impact upon them, are key determinants of drug-related harm and access to interventions and hospital services. These findings point to the need to modify and scale up existing safer environment interventions, and expand these into hospital settings, to mitigate the impacts of contextual forces on IDU and better address their health needs.
