Exploring what shapes injection and non-injection among a sample of marginalized people who use drugs

Abstract

Background: Few studies have specifically explored what influences people who use drugs to consume them in certain ways (i.e., smoking, injecting). While a great deal of research has examined the transition from non-injection to injection routes of drug administration, less is known about people who use drugs (PWUD) but have never injected or have stopped injecting. This paper draws on actor-network theory to explore what moves people to inject or not, among both people who currently smoke/sniff drugs (PWSD) and people who currently inject drugs (PWID), to better understand factors that shape/influence methods of drug consumption.

Methods: Two-stage interviews (a quantitative survey followed by a qualitative interview) were conducted with 26 PWSD and 24 PWID. Interviews covered a range of topics related to drug use, including reasons for injecting drugs, never injecting, and stopping injecting. Data were analysed by drawing on actor-network theory to identify forces involved in shaping drug consumption practices.

Results: We present three transformative drug use events to illustrate how specific methods of drug consumption are shaped by an assemblage of objects, actors, affects, spaces and processes. Rather than emphasising the role of broad socio-structural factors (i.e., poverty, drug policy) participant narratives reveal how a variety of actors, both human and non-human, assembled in unique ways produce drug consumption events that have the capacity to influence or transform drug consumption practices.

Conclusion: Actor-network theory and event analysis provide a more nuanced understanding of drug consumption practices by drawing together complex material, spatial, social and temporal aspects of drug use, which helps identify the variety of forces involved in contexts that are thought to shape substance use. By attending to events of drug consumption we can better understand how contexts shape drug use and related harms. With greater insight into the transformative capacity of drug use events, strategies may be better tailored to prevent drug use-related harms.
