Evidence of harms associated with temazepam gel capsule injecting among injecting drug users in Australia led to its withdrawal from manufacture in Australia. Subsequently, diphenhydramine gel capsule injecting was identified among a subset of ethnic Vietnamese injecting drug users.
Observational fieldwork around an active street-based illicit drug marketplace together with targeted purposive sampling enabled 66 ethnic Vietnamese injecting drug users to be recruited for in-depth interview.
Data revealed that the injection of gel capsules increases exposure to non-viral infections. Analysis of participant interviews show how participants have established their own ways of reducing these harms including thinning the drug solution by jacking regularly during injection. Controversially, femoral vein administration of diphenhydramine-heroin cocktails was also seen as a harm reduction strategy by participants.
Health education campaigns to address the potentially negative consequences of gel capsule groin injection will not be successful unless health workers and policy makers work with drug users and incorporate local understandings and meanings of risk in health promotion activities.

    • "The importance of early engagement with vulnerable CALD communities is best highlighted by the emergence of IDU among Southeast Asian communities in Melbourne and Sydney in the 1990s (Higgs, Maher, Jordens, Dunlop, & Sargent, 2001; Maher et al., 2001). Research identified a variety of cultural beliefs and practices that placed ethnic Vietnamese people who inject drugs (PWID) at risk of harms, particularly blood-borne virus transmission and injuries resulting from unsafe injecting practices (Higgs et al., 2009; Higgs, Owada, Hellard, Power, & Maher, 2008; Ho & Maher, 2008; Maher et al., 2001), enabling health workers to respond to their unique needs in a timely manner. Communities from Sub-Saharan Africa are among the fastest-growing migrant groups in "

    ABSTRACT: Little is known about injecting drug use (IDU) among people from culturally and linguistically diverse backgrounds in Australia. We interviewed 18 young people of African ethnicity (6 current/former injectors, 12 never injectors) about exposure and attitudes to IDU. Exposure to IDU was common, with IDU characterized as unnatural, risky and immoral. IDU was highly stigmatized and hidden from family and friends. There is a need for culturally appropriate programs to promote open dialogue about substance use to reduce stigma and prevent African youth who may use illicit drugs from becoming further marginalized.

    ABSTRACT: The dominant Australian approaches to understanding illicit drug marketplaces are surveillance and criminological research. These approaches rely on the elementary neoclassical economic model of the market which focuses primarily on supply and demand. In this paper, we draw on anthropological and sociological research to develop an alternative framework for understanding Australian illicit drug marketplaces that emphasises their constituent processes. The paper draws on two years of ethnographic research among heroin user/sellers of Vietnamese ethnicity in an Australian heroin marketplace. Trade and barter were key modes of exchange in this marketplace. We identified active negotiation and bargaining over price on the basis of social relationships, with dealers and customers actively working to develop and maintain such ties. Dealers set price collectively and this was shaped by moral and cultural elements such as notions of a 'fair' price. Social processes and relations as well as shared cultural expectations helped to generate trust and maintain order in the marketplace. Our ethnographic research suggests that the dominant Australian approaches to the study of illicit drug markets, with their reliance on the elementary neoclassical economic market model, ignore the social processes and social relations through which such sites are made and remade. Nor do they adequately capture the complex character of the subjects who act within these sites. If we are to expand our understanding of illicit drug markets and marketplaces in Australia, we must look beyond the conceptions offered by surveillance and criminological approaches.

    ABSTRACT: Consumption of prescription opioid analgesics (POAs) in Australia has increased steadily in recent years, raising concerns of increasing harms including overdose and dependence, as has occurred in the USA. Exposition of the Royal Australasian College of Physicians Prescription Opioid Policy with reference to the published literature, drawing out principles for harm reduction for psychoactive pharmaceutical drugs. Complex professional, patient, regulatory and market factors influence health professionals balancing the benefits and harms of POAs. Owing to the potential for diversion, overlapping markets probably exist for pharmaceutical opioids used for populations with cancer pain, chronic non-cancer pain, and people dependent on pharmaceutical and illicit opioids (including those needing opioid substitution treatment). Attempts to reduce or restrict supply in one area may increase demand in others. There is a need to consider new harm reduction strategies for people with problematic pharmaceutical opioid use. These people are demographically not well characterised, and may be distinct from the more familiar population of injection drug users. Harm reduction is a valid approach for POAs. However, the role of health professionals as gatekeepers of opioid supply, the need to optimise health benefits of POAs, and the likely interplay of complex market forces among populations consuming opioids have no close parallel in harm reduction for other substances. This poses fundamentally different challenges. Reducing inappropriate supply and demand for POAs while maximising their benefits and minimising their harms may improve health outcomes.
