Pharmaceutical opioid use among oral and intravenous users in Australia: A qualitative comparative study.

BACKGROUND: Between 1992 and 2012 dispensing episodes for pharmaceutical opioids (PO) in Australia increased from 500000 to 7500000. In the US, increases in the prescription of PO have been linked to increases in opioid-related morbidity and mortality and transitions to heroin injection. However, Australian data indicate that morbidity and mortality related to PO are relatively low, particularly when compared to heroin and other drugs. This paper explores the characteristics and patterns of non-medical pharmaceutical opioid (NMPO) use among a sample of young people in Sydney, Australia. METHODS: During 2015, we conducted in-depth qualitative interviews with 34 young people who use PO non-medically by oral (n=22) and intravenous (n=12) routes of administration. RESULTS: Oral NMPO users were a more affluent group who clustered around the Northern, Inner and Eastern suburbs of Sydney, while the intravenous users came from a range of locations including rural/regional areas of NSW and socioeconomically disadvantaged suburbs of South Western Sydney. Oral users were characterised by intermittent and largely self-limiting NMPO use and reported few health and social consequences. Intravenous users reported heavy and frequent drug, including NMPO, use and a range of adverse health and social consequences including overdose, injecting risk behaviour, hepatitis C virus (HCV) infection and residential instability. CONCLUSION: Results highlight the significance of social and structural factors in trajectories of opioid use and related harms. Factors such as stable housing and family relationships, disposable income and close social networks observed in young oral NMPO users may help to explain differences in patterns of NMPO use and related outcomes between the two groups.

Self-limiting non-medical pharmaceutical opioid use among young people in Sydney, Australia: An exploratory study.

INTRODUCTION AND AIMS: Indicators suggest an escalation in opioid use globally, with recent HIV outbreaks linked to non-medical pharmaceutical opioid (NMPO) use. Little is known about how young Australians engage in NMPO use. DESIGN AND METHODS: During 2015, we conducted qualitative interviews with young people (16-29 years) who reported oral NMPO use at least twice in the past 90 days. The study included a sample of injecting (n = 14) and oral (n = 22) users. This paper focuses on the oral user group. RESULTS: Most participants grew up in affluent areas of Sydney, reported few health problems, rarely accessed health or welfare services and had limited contact with police. NMPO use was part of a repertoire of drug use involving: (i) use to come down from stimulants; (ii) use in conjunction with cannabis and alcohol; and (iii) use by itself. Participants reported limiting their use in order to avoid stigma and dependence. DISCUSSION AND CONCLUSIONS: Results suggest culture of self-limiting NMPO use characterised by stable housing, disposable income and intimate friendship networks. Despite the adverse health outcomes observed in other settings, our data suggest that the patterns and meanings of NMPO use observed in this small sample may help explain the limited nature of problematic use among young Australians to date. Findings indicate a need for epidemiological data, including longitudinal data, to assess possible demographic shifts in NMPO use in Australia, and to address risk factors for dependence and transitions to injecting and heroin use in this population.
