Using drugs alone in single room occupancy housing: Understanding environmental drivers of overdose risk.

Background: Across North America most overdose deaths occur in housing, largely due to individuals using drugs alone. In cities, fatalities are disproportionately concentrated in low-income housing, including single room occupancy (SRO) housing. While research has highlighted how SROs operate as risk environments for various poor outcomes, there has been little attention to specific drug use practices (i.e., using alone) associated with overdose vulnerability in these spaces. This study explores how environmental contexts of SROs shape overdose risks, with specific attention to practices of using drugs alone.

Methods: In-depth semi-structured interviews were conducted with 30 people who use drugs (PWUD) living in Vancouver SROs. Interviews covered topics such as social-structural environments of housing, drug use practices, and housing-based harm reduction. Thematic analysis drew on the intersectional risk environment framework.

Results: Narratives positioned SROs as extensions of public space, with similar expectations of risks and behaviours as in public spaces. For some participants, using alone in their room was characterized as a practice in claiming privacy within the context of a public existence. Participants highlighted how certain features of SRO's social-structural environments were routinely leveraged against them (e.g., security cameras, staff surveillance), suggesting using alone as a tactic to minimize risks of hyper-surveillance and punitive policies. Further, participants discussed using alone as "safer," describing how this practice mitigated place-based risks of social-structural harms (e.g., violence, criminalization) in ways that eclipsed overdose risk.

Conclusion: Using drugs alone may be understood as a spatial negotiation of vulnerability to diverse harms produced by environmental contexts of SROs. Interventions accounting for broader contextual factors (e.g., improvements housing quality/quantity, providing a safer supply of drugs) that render using alone as instrumental to survival, and that reduce the implicit threat of punishment from intensive surveillance and control practices are critical to reduce vulnerability to overdose and other harms.
