Background: Impurities in commonly used illicit drugs raise concerns for unwitting consumers when pharmacologically active adulterants, especially new psychoactive substances (NPS), are used. This study examines impurities detected in illicit drugs seized in one Australian jurisdiction., Methods: Queensland Health Forensic and Scientific Services provided analytical data. Data described the chemical composition of 9346 samples of 11 illicit drugs seized by police during 2015-2016. Impurities present in primary drugs were summarized and tabulated. A systematic search for published evidence reporting similar analyses was conducted., Results: Methamphetamine was the primary drug in 6608 samples, followed by MDMA (1232 samples) and cocaine (516 samples). Purity of primary drugs ranged from ∼30% for cocaine, 2-CB and GHB to >90% for THC, methamphetamine, heroin and MDMA. Methamphetamine and MDMA contained the largest variety of impurities: 22 and 18 variants, respectively. Drug adulteration patterns were broadly similar to those found elsewhere, including NPS, but in some primary drugs impurities were found which had not been reported elsewhere. Psychostimulants were adulterated with each other. Levamisole was a common impurity in cocaine. Psychedelics were adulterated with methamphetamine and NPS. Opioids were quite pure, but some samples contained methamphetamine and synthetic opioids., Conclusions: Impurities detected were mostly pharmacologically active adulterants probably added to enhance desired effects or for active bulking. Given the designer nature of these drug cocktails, the effects of the adulterated drugs on users from possible complex multi-drug interactions is unpredictable. Awareness-raising among users, research into complex multi-drug effects and ongoing monitoring is required., (Copyright © 2019. Published by Elsevier B.V.)

Objective: Describe program theories of substance misuse interventions with Aboriginal and Torres Strait Islander (Indigenous) Australians funded by the National Health and Medical Research Council (NHMRC) since the 'Roadmap' for Indigenous health., Methods: Projects funded 2003-2013 were categorised by intervention strategies. Realist concepts informed the program theory: intended resources and responses; influence of context on outcomes; explicit and implicit program assumptions., Results: Seven interventions were included. Three randomised controlled trials targeted tobacco using psychosocial interventions in primary health centres using the program theory: "Local Indigenous health workers extend and sustain the effects of conventional clinical brief intervention by engendering social and cultural resources". Four pragmatic trials of multiple-component, community-based interventions using controlled, semi-controlled or before-and-after designs used the program theory: "Discrete intervention components targeting locally defined substance misuse issues will activate latent capacities to create an environment that favours cessation." Publications did not report clear effect, implementation fidelity or explicit mechanisms affecting participant thinking., Conclusions: Rigorous intervention designs built on 'Roadmap' principles neither reduced substance use in the populations studied nor identified transferable mechanisms for behaviour change. Implications for public health: Substance misuse impacts among Indigenous Australians remain severe. Theoretical mechanisms of behaviour change may improve intervention design., (© 2017 The Authors.)

Background: 'Alcohol Management Plans' (AMPs) with a focus on alcohol restrictions were implemented in 19 discrete Indigenous communities, in 15 Local Government Areas, by the Queensland Government from 2002. Community residents' perceptions and experiences of the impacts of AMPs on local alcohol and drug use are documented., Methods: A cross-sectional study used quantitative and qualitative survey data collected during 2014-2015 in 10 affected communities. Five had some alcohol available. Five had total prohibition. Participant responses were assessed and compared by prohibition status., Results: Overall, less than 50% of 1098 participants agreed that: i) the restrictions had reduced alcohol availability in their community and ii) that people were drinking less. Nearly three quarters agreed that binge-drinking had increased, attributed to increased availability of illicit alcohol. There were no statistically significant differences between communities with prohibition and those with some access to alcohol. Participants agreed overall that cannabis use had increased but were more equivocal that new drugs were being used. These views were less frequently reported in prohibition communities., Conclusions: Contrary to what was intended, Queensland's alcohol restrictions in Indigenous communities were viewed by community residents as not significantly reducing the availability and use of alcohol. Furthermore, this was compounded by perceived increases in binge drinking and cannabis use; also unintended. There is a need to strengthen resolve at all levels to reduce the supply of illicit alcohol in restricted areas., (Copyright © 2016 The Author(s). Published by Elsevier B.V. All rights reserved.)

Background: Favourable impacts are reported from complex alcohol control strategies, known as 'Alcohol Management Plans' (AMPs) implemented 14 years ago in 19 Aboriginal and Torres Strait Islander (Indigenous) communities in Queensland (Australia). However, it is not clear that all communities benefited and that positive impacts were sustained. Service providers, key stakeholders and community leaders provided insights about issues and impacts., Methods: Participants (N=382) were recruited from knowledgeable and experienced persons using agency lists and by recommendation across sectors which have a mandate for managing alcohol-related issues and consequences of AMP policies in communities. In semi-structured interviews, participants (51% Indigenous, 55% male and comprised of at least one-third local community residents) were asked whether they believed alcohol controls had been effective and to describe any favourable and unfavourable outcomes experienced or perceived. Inductive techniques were used for thematic analysis of the content of transcribed recorded interviews. Comments reflecting themes were assessed across service sectors, by gender, Indigenous status and remoteness., Results: Participants attributed reduced violence and improved community amenity to AMPs, particularly for 'very remote' communities. Participants' information suggests that these important achievements happened abruptly but may have become undermined over time by: the availability of illicit alcohol and an urgency to consume it; migration to larger centres to seek alcohol; criminalization; substitution of illicit drugs for alcohol; changed drinking behaviours and discrimination. Most issues were more frequently linked with 'very remote' communities., Conclusion: Alcohol restrictions in Queensland's Indigenous communities may have brought favourable changes, a significant achievement after a long period of poorly regulated alcohol availability from the 1980s up to 2002. Subsequently, over the past decade, an urgency to access and consume illicit alcohol appears to have emerged. It is not clear that relaxing restrictions would reverse the harmful impacts of AMPs without significant demand reduction, treatment and diversion efforts., (Copyright © 2016 Elsevier B.V.

Very high rates of injury and death during the 1990s were linked with increased alcohol availability and misuse in discrete Indigenous communities in rural and remote Queensland (Australia). To address widespread concerns about a public health crisis, from 2002, the Queensland Government implemented alcohol control strategies known as 'Alcohol Management Plans' (AMPs) in 19 of these communities. Although resources for prevention and treatment were promised, AMPs became increasingly focused on local prohibition, restricted access to alcohol and punitive measures for breaching restrictions. An examination of legislation, regulations, explanatory notes, and published documents indicates this focus evolved across four phases since 2002. The first phase, from 2002 to 2004, saw 'restricted areas' with alcohol 'carriage limits' introduced, restricting the amounts and types of liquor permitted within some communities. The second phase (2002-2007) featured evaluations and reviews by the Queensland Government bringing recommendations for more stringent controls. Additionally, beyond the 'restricted areas', licenced premises situated within the 'catchments' of the targeted communities, mainly located in the nearby regional towns, became subject to 'minimising harm' provisions. These more stringent controls were implemented widely in the third phase (2008-2011) when: the operations of seven community-managed liquor outlets were terminated; the trading arrangements of two others were modified; Police powers to search and seize were increased; and 'attempting' to take liquor into a 'restricted area' also became an offence. Some communities have seen a reduction in alcohol-related harms that have been attributed to these alcohol control strategies. This commentary maps the recent regulatory history of Queensland's alcohol controls targeting discrete Indigenous communities highlighting their increasing focus on punitive measures to reduce access to alcohol. With AMPs in Queensland currently under Government review, and with community resolve for change rising, the limits to Government controls and punitive measures may have been reached., (Copyright © 2015 Elsevier B.V.

Background: Smoking prevalence in Aboriginal and Torres Strait Islander pregnant women is quadruple that of non-Indigenous counterparts, impacting on the health of babies and children., Aims: To explore attitudes and experiences related to prenatal tobacco smoking by Aboriginal women and household smoking, and to provide recommendations for culturally appropriate interventions., Methods: We conducted five focus groups with clients and family members of a regional NSW Aboriginal maternity service (n=18). Committees, including Aboriginal representatives, oversaw the study. We analysed transcripts with the constant comparative method and developed key categories., Findings: Categories included: social and family influences, knowing and experiencing the health effects of smoking, responses to health messages, cravings and stress, giving up and cutting down, managing smoke-free homes and cars, and community recommendations. Smoking in pregnancy and passive smoking were acknowledged as harmful for babies and children. Anti-tobacco messages and cessation advice appeared more salient when concordant with women's lived experience. Reduced cigarette consumption was reported in pregnancy. Despite smoking in the home, families were engaged in the management of environmental tobacco smoke to reduce harm to babies and children. Abstinence was difficult to initiate or maintain with the widespread use of tobacco in the social and family realm., Conclusion: Anti-tobacco messages and interventions should relate to Aboriginal women's experiences, improve understanding of the quitting process, support efficacy, and capitalise on the positive changes occurring in smoke-free home management. Focus group participants recommended individual, group and family approaches, and access to cessation services and nicotine replacement therapy for Aboriginal pregnant women who smoke., (Copyright © 2013 Australian College of Midwives.

Objective: To review available literature addressing the issue of whether smoking status of Indigenous Health Workers (IHWs) impedes provision of health information about smoking tobacco to their communities., Method: Databases were searched for publications that examined IHWs' smoking status or quit support programs for IHWs. Studies were categorised as reviews and commentaries, intervention studies or descriptive research., Results: Fourteen studies met inclusion criteria. Overall, the literature suggests that IHWs' smoking status is a barrier. However, the poor quality of most studies weakens the evidence for this conclusion. The issue of IHWs smoking status as a barrier is peripheral to all but two of the studies. Literature cited and reviewed was often not exhaustive and relied on only a few preceding empirical studies. Most studies were unclear about whether IHWs' views were reported as distinct from views of health staff in general., Conclusions and Implications: The recent COAG investment to Tackling Smoking is an important contribution to Closing the Gap in the health of Indigenous Australians. However, there remain potential barriers faced by IHWs that may undermine efforts to reduce Indigenous smoking. Overcoming these barriers and assisting IHWs to quit smoking may provide an opportunity to address high rates of smoking in Indigenous communities. Further research is required with a balance between descriptive research to assess the issue and intervention research to address it., (© 2011 The Authors.

Controlling dengue fever in Australia and internationally, relies heavily upon the actions of residents as well as community education and awareness of the risks. Although it has been well established in medical anthropology that the success of health interventions is highly dependent upon a clear grasp of lay knowledge of disease, limited attention has been given to lay understandings of dengue fever and its vectors in the extant literature. We begin addressing this hiatus through an examination of north Queensland residents' knowledge of the breeding habitats of Aedes aegypti mosquitoes. Building on the insights of earlier social research, we use factor analysis to examine the results of a series of randomly selected telephone surveys and compare responses over time and between cities. Our analysis confirms that many people assume that Ae. aegypti is ubiquitous in the landscape, that it lives and breeds not only around the home, but also in a variety of geographical spaces located beyond the suburban 'backyard', and beyond the control of local residents. Lay understandings appear to be placing people at risk from dengue, influencing the mosquito management practices of local residents and acting as a source of resistance to public health messages that focus on individual responsibility. A way forward through the provision of new information that challenges key assumptions is provided in the discussion. We argue that rather than dismissing lay understandings as ignorance, strategies, practices and policy based on a detailed understanding of this knowledge will mean that practitioners are better able to address these assumptions and will likely be more effective at educating the public of the risks posed by dengue., (Copyright 2010 Elsevier B.V.

Objective: To describe and discuss challenges and opportunities encountered when estimating tobacco consumption in six remote Aboriginal communities using tobacco sales data from retail outlets., Approach: We consider tobacco sales data collected from retail outlets selling tobacco to six Aboriginal communities in two similar but separate studies. Despite challenges--including: not all outlets provided data; data not uniform across outlets (sales and invoice data); change in format of data; personnel change or management restructures; and anomalies in data and changes in community populations--tobacco consumption was estimated and returned through project newsletters and community feedback sessions. Amounts of tobacco sold were returned using graphs in newsletters and pictures of items common to the community in community feedback sessions., Conclusions: Despite inherent limitations of estimating tobacco consumption using tobacco sales data, returning the amount of tobacco sold to communities provided an opportunity to discuss tobacco consumption and provide a focal point for individual and community action. Using this method, however, may require large and sustained changes be observed over time to evaluate whether initiatives to reduce tobacco consumption have been effective., Implications: Estimating tobacco consumption in remote Aboriginal communities using tobacco sales data from retail outlets requires careful consideration of many logistical, social, cultural and geographic challenges.

Objective: Estimating illicit substance use in epidemiological studies is challenging, particularly across ethical, cultural and language barriers. While developing the methods for a case-control study of the effects of heavy kava consumption among Aboriginal people in remote Northern Territory (NT), we examined the validity and utility of alternative methods for estimating exposure., Methods: We assessed the level of agreement between a consensus of Aboriginal health workers in two different communities using interviews conducted with community members and health workers and individuals' self-reported kava consumption. Exposure measures included history of kava use, current kava use and history of heavy use. Agreement between a health worker consensus classification and individuals' self-report was analysed and agreement among several health workers in a consensus classification without self-report was assessed., Results: Health workers concurred about an individual's history of kava use (k=0.83), current use (k=0.43) and also level of use (k=0.33). There was very good agreement between health workers' consensus and self-reported history of use (k=0.77). Agreement among health workers about current kava use was poor (k=0.08), while there was fair agreement between health workers and self-reported heavy kava users (k=0.36). Data from review of clinic patient notes supported agreement between consensus classification and self-reported history and level of use (k=0.39)., Conclusions: Self-reported kava use may be a poor estimate of current use especially when obtained from interviews away from a confidential clinic setting. Consensus classification by knowledgeable Aboriginal health workers provided comprehensive coverage, efficiently and with greater reliability and assisted to identify 'excessive' kava use.
