The Australian Government will set the direction for addressing road safety over the next decade with its 2021-2030 National Road Safety Strategy. This road map will detail objectives and goals agreed upon by all Australian states and territories. Similar to previous national strategies, Aboriginal and Torres Strait Islander (Indigenous) Australians are a high priority population. Indigenous Australians are over-represented in serious injury and fatal road crashes, with alcohol a leading factor. Therapeutic and educational programs are a major strategy among the suite of measures designed to reduce and prevent drink driving in Australia. The release of this new strategy provides a timely opportunity to reflect on what is known about drink driving among Indigenous Australians and to consider the suitability of existing therapeutic and educational drink driving programs for Indigenous Australian contexts. Here, we summarise factors that contribute to drink driving in this population and identify outstanding knowledge gaps. Then, we present an overview of drink driving programs available for Indigenous Australians along with suggestions for why tailored programs are needed to suit local contexts. The response to address drink driving among Indigenous Australians has been fragmented Australia-wide. A coordinated national response, with ongoing monitoring and evaluation, would improve policy effectiveness and inform more efficient allocation of resources. Together this information can help create suitable and effective drink driving programs for Indigenous drivers and communities Australia-wide., (© 2021 The Authors.

This closing commentary to the special section presents an overview of the Queensland Alcohol-related violence and Night-Time Economy Monitoring evaluation findings in comparison to those from other jurisdictions where similar interventions have been implemented (such as Sydney and Newcastle), and especially with previous studies that have used similar evaluation methodologies, such as the Dealing with Alcohol and the Night-Time Economy study. Overall, the articles documented promising reductions in alcohol-related harm, building on the existing evidence base for multi-pronged interventions in entertainment districts. Importantly, this is the first comprehensive investigation to also look at impacts on nightlife-related business and findings demonstrated, that there were improvements for many businesses. There are substantial policy implications for Queensland and other jurisdictions (nationally and globally) wanting to reduce late night alcohol-related harm in entertainment districts., (© 2021 Australasian Professional Society on Alcohol and other Drugs.)

This commentary introduces the special section on the outcomes of the Queensland Alcohol-related violence and Night-time Economy Monitoring project and outlines the political and policy context of the interventions put in place under the Queensland government's Tackling Alcohol-Fuelled Violence strategy. The development of the strategy was informed by alcohol policy initiatives trialled in other major Australian cities over the past two decades. The articles in this special section examine the impact of the Tackling Alcohol-Fuelled Violence policy stages on alcohol-related harms and local economies across selected entertainment precincts (Safe Night Precincts). A rich array of data were utilised, including administrative health and justice data, data reflective of nightlife trading (i.e. foot traffic data, ID scanner data and live music performances) and street surveys. Findings have implications for research, policy and practice and demonstrate the need for comprehensive evaluations that can accommodate the complexities of modern alcohol policy in Australia., (© 2021 Australasian Professional Society on Alcohol and other Drugs.)

Introduction and Aims: In July 2016, the Queensland government introduced the Tackling Alcohol-Fuelled Violence policy, with some amendments over the subsequent 12 months. Key measures included restricting alcohol sales to 3 am in safe night precincts (SNPs), limiting the annual number of extended trading permits (i.e. trading until 5 am) and introducing mandatory networked identification scanners. We examined the policy impact on the number of serious assaults across all combined SNPs and in five major SNPs: Fortitude Valley, Cairns, Surfers Paradise, Toowoomba and Townsville., Design and Methods: Using police data (July 2009-June 2019), we examined the impact of the policy on serious assaults during high-alcohol hours (high-alcohol hours; 8 pm-6 am, Friday and Saturday), employing time series methods., Results: Across all SNPs there was no significant change in the number of serious assaults during overall high-alcohol hours, but a significant 49% decrease in the monthly number of serious assaults between 3 am and 6 am on Friday/Saturday. A significant decrease in the monthly count of serious assaults during high-alcohol hours and specifically 3 am-6 am on Friday/Saturday was evident in Fortitude Valley SNP (52%), and during high-alcohol hours in Toowoomba SNP (43%)., Discussion and Conclusions: Although results were mixed, there was evidence of some promising reductions in alcohol-related violence in SNPs. It is likely that factors such as extended trading permits (venues not closing at 3 am), continued drinking in some venues and 24-h trading in casinos have reduced the potential impacts seen elsewhere., (© 2021 Australasian Professional Society on Alcohol and other Drugs.)

Introduction and Aims: In Arnhem Land's remote Aboriginal communities [Northern Territory], very high smoking rates and overcrowding mean high exposure to Environmental Tobacco Smoke. This study compared smokers who restrict their smoking in these environments with those who do not., Design and Methods: In 2008-2009, 258 smokers (137 males and 121 females) aged ≥ 16 years, provided information permitting categorisation of those who 'RESTRICT' their smoking in the house, car or workplace from those who do 'NOT RESTRICT'. Univariable and multivariable logistic regressions compared 'RESTRICT' and 'NOT RESTRICT' groups by gender, age group, daily use, tobacco consumption, time-to-first-cigarette and quit intentions. Those in the 'RESTRICT' group explained their motivations, summarised using qualitative data analysis., Results: Men were almost twice as likely to 'NOT RESTRICT' their smoking (odds ratio = 1.88, 95% confidence interval = 1.14-3.08, P = 0.013). Time-to-first-cigarette was the strongest predictor to 'NOT RESTRICT' in women (odds ratio = 3.48, 95% confidence interval = 1.44-8.41, P = 0.006) with daily consumption the strongest predictor in men (odds ratio = 3.15, 95% confidence interval = 1.39-7.18, P = 0.006). Men and women shared similar motivations for restricting smoking., Discussion and Conclusions: Smoke-free homes and workplaces are important opportunities to reduce exposure to Environmental Tobacco Smoke in remote Indigenous communities., (© 2013 Australasian Professional Society on Alcohol and other Drugs.)

Introduction and Aims: Anecdotal reports suggest that high rates of cannabis use and dependence are significant issues in Indigenous communities in north Queensland; however, there is little scientific evidence to support or refute this. The Cape York Cannabis Project seeks to investigate cannabis use rates, cannabis dependence and mental health impacts for the first time in three Cape York Indigenous communities., Design and Methods: The current study reports preliminary findings, resulting from interviews with 133 Indigenous participants aged 14-47 years from one Cape York community. Quantitative data were gathered on rates of cannabis use, cannabis dependence as measured by a score of ≥ 3 the Severity of Dependence Scale. Qualitative self-report data were gathered concerning mental health impacts of cannabis and reasons for quitting., Results and Conclusions: Very high rates of cannabis use were identified, with 66.2% of males and 30.5% of females interviewed being current users. An additional 12.2% of males and 30.5% of females were former users, and 21.6% of males and 39% of females had never used cannabis. High rates of cannabis dependence were also observed. Of those current users who used cannabis at least weekly, 67.7% reported cannabis dependence. A range of mental health impacts due to cannabis were reported. In total, 76.1% of current users were considering quitting or cutting down. Rates of use and dependence were much higher than national rates, and indicate significant mental health harms due to cannabis. Further investigation of mental health impacts of cannabis is required, as is intervention to reduce these impacts., (© 2011 Australasian Professional Society on Alcohol and other Drugs.)

Introduction and Aims: While petrol sniffing afflicts several isolated Indigenous groups internationally, few studies have examined the factors contributing to continued sniffing following treatment.This study aims to describe those factors in a group of Aboriginal Australian users., Design and Methods: During residential treatment, 56 petrol sniffers completed baseline demographic and substance use questionnaires and cognitive and psychological assessments. Eighty per cent were reassessed and interviewed an average of 9 months (SD = 4) later. Cognitive, psychological, substance use and sociocultural factors were compared between those who relapsed at follow up and those who maintained abstinence., Results: More males (n = 44) than females (n = 12) were studied. Of the 45 individuals followed up, 58% (n = 26) relapsed. Significant risk factors for relapse included the ready availability of petrol, living in urban centres, being unmarried and living with fewer people (P < 0.05). Other potential risk factors, indicated by P-values < 0.10, included younger age of first petrol use, having sniffed within 14 days prior to treatment, poly substance use, sniffing in response to negative emotions, and feeling lonely at baseline and having sleep problems at follow up., Discussion and Conclusion: This study identified psychosocial factors that may be associated with continued petrol sniffing among Aboriginal Australians post treatment. Future research, interventions and policy relating to petrol sniffing should consider these factors.

Introduction and Aims: In remote Indigenous Australian communities measuring individual tobacco use can be confounded by cultural expectations, including sharing. We compared self-reported tobacco consumption with community-level estimates in Arnhem Land (Northern Territory)., Design and Methods: In a cross-sectional survey in three communities (population 2319 Indigenous residents, aged ≥16 years), 400 Indigenous residents were interviewed (206 men, 194 women). Eight community stores provided information about tobacco sold during the survey. To gauge the impact of 255 non-Indigenous residents on tobacco turnover, 10 were interviewed (five men, five women). Breath carbon monoxide levels confirmed self-reported smoking. Self-reported number of cigarettes smoked per day was compared with daily tobacco consumption per user estimated using amounts of tobacco sold during 12 months before the survey (2007-2008). 'Lighter smokers' (<10 cigarettes per day) and 'heavier smokers' (≥10 cigarettes per day) in men and women were compared., Results: Of 400 Indigenous study participants, 305 (76%) used tobacco; four chewed tobacco. Of 301 Indigenous smokers, 177 (58%) provided self-reported consumption information; a median of 11-11.5 cigarettes per day in men and 5.5-10 cigarettes per day in women. Men were three times (odds ratio=2.9) more likely to be 'heavier smokers'. Store turnover data indicated that Indigenous tobacco users consumed the equivalent of 9.2-13.1 cigarettes per day; very similar to self-reported levels. Sixty per cent (=6/10) of non-Indigenous residents interviewed were smokers, but with little impact on tobacco turnover overall (2-6%)., Discussion and Conclusions: Smoking levels reported by Indigenous Australians in this study, when sharing tobacco was considered, closely reflected quantities of tobacco sold in community stores., (© 2010 Australasian Professional Society on Alcohol and other Drugs.)

Introduction and Aims: This study examined prevalence and predictors of alcohol consumption and alcohol problems in a sample of medical students in Vietnam., Design and Methods: A cross-sectional survey using a multi-stage cluster sampling approach was conducted in 2007 in two universities in Vietnam. The students (n = 619, 100% response rate) completed questionnaires based on the Alcohol Use Disorder Identification Test. A score of >or=8 defined presence of alcohol problems. Data analyses adjusted for the cluster sampling approach., Results: Overall 65.5% of students had drunk alcohol during the previous year while alcohol problems were detected in 12.5%. Male students, students who reported that their family members drank and students who reported that their flat mates were drinking were more likely to be current drinkers. Male students were 14.3 times more likely to have an Alcohol Use Disorder Identification Test score of >or=8 compared with female students (P = 0.005)., Discussion and Conclusions: Intervention programs focusing on male students and their social environment are warranted. As Vietnamese society rapidly modernises prevention programs for female students may also be needed.

Introduction and Aims: To examine predictors of cannabis use at 5 year follow up in an Australian Aboriginal cohort., Design and Methods: A longitudinal study consisting of two waves of data collection 5 years apart was conducted. Of the 100 Aboriginal residents (aged 13-36 years) interviewed about cannabis use in 2001, 83 were re-interviewed in 2005-2006 from three remote communities in Arnhem Land, Northern Territory, Australia. Self-reported cannabis use was categorised at each time point (none; former use, quit > or = 3 months; lighter use, < 6 cones, 2-3 times weekly; daily use, > or = 6 cones, daily) and summarised as any current use, heavy use, dependence or cessation. Other substance use, employment and involvement in school or training were also compiled., Results: Most respondents who reported cannabis use at baseline again reported use at follow up. A history of petrol sniffing predicted later heavy cannabis use (P < 0.05). Trends were evident for men to have persisting cannabis use, and for employment and/or engagement in school or training to be associated with cannabis cessation., Discussion and Conclusions: Ongoing heavy cannabis use is commonplace in this Aboriginal cohort and raises concerns for the physical, social and psychiatric burden on these already vulnerable communities. Prevention, treatment and intervention programs developed with communities are badly needed.

Introduction and Aims: Diversion from court and prison has been recommended for Indigenous Australian youth who commit offences. As no evaluations of such programmes have been published, we describe processes and early outcomes of a diversion programme in the Northern Territory., Design and Methods: From 2003 to 2006, among 1700 remote Indigenous community residents, 35 young people (aged 11-18 years, median 15 years) committed offences. They were diverted from criminal justice and referred to a community-based diversion initiative. Client assessment records and staff interviews furnished data to examine clients' diversion pathways and early programme results., Results: Eighteen clients were reportedly using a substance at the time of their offence; cannabis (n = 9), petrol (n = 5), alcohol (n = 4). The remaining 17 had histories of using one or more of these. Two clients could not complete local diversion programs because they moved to other regions; one case was not pursued for legal reasons, leaving 32 clients exposed to the local programme. By July 2006, four clients were continuing in their programmes, three had breached them, but 25 had completed them in periods ranging from 2 to 60 weeks (median = 26 weeks), a completion rate of 89% (25/28). Just one client re-offended after completing diversion., Discussion and Conclusions: A high completion rate was achieved despite: a dearth of locally available drug and alcohol treatment services and diversion options; shifts in police approaches; heavy administrative burdens to meet legal requirements; and difficulties communicating across cultural barriers.

Introduction and Aims: We evaluated a community-driven initiative established to prevent substance misuse and increase respect for culture and their elders among young people in a group of remote Aboriginal communities in Arnhem Land, Northern Territory (NT), Australia. The Youth Development Unit provided a range of training, recreational and cultural activities within a community development framework to all young people in the community., Design and Methods: Methods of operation, community acceptability, perceived impact and likely ability to meet goals were assessed. Data included community, staff and stakeholder interviews and observation. School attendance, youth apprehension rates and information on levels of substance use were compared 2 years before and after the initiative was implemented., Results: Interviewees reported increased youth training and recreational opportunities, increased communication between local agencies, overall satisfaction with programme delivery and optimism that it could achieve its goals. Suggested improvements included even more training, cultural programmes and other activities and employment of more community-based Indigenous staff. The importance of key staff, involvement of a respected Indigenous staff member and community engagement were noted as probable contributors to its success., Discussion and Conclusions: Indigenous young people in Australia remain one of the most disadvantaged and vulnerable groups. Community-driven preventive initiatives offer enhanced youth resilience and connectedness in remote Aboriginal communities and alternatives to substance use.

The objective of this study was to describe some costs and challenges for conducting follow-up interviews about substance use in Indigenous groups in northern Australia. In a remote region in the Northern Territory in 2001, 131 Indigenous people (aged 13 - 36 years) were approached for interview regarding their substance use. Of these, 108 (54 males, 54 females) were interviewed successfully. Follow-up interviews were attempted in 2004. Study records traced progress and costs. In 2001, the response rate was 82% (108/131). In 2004, 22 participants could not be found after four attempts although they were known by health workers to still reside in the region. Fifteen were not residing in the region during 2004 and were lost to follow-up, four were in prison and three were deceased. Fourteen contacted either refused directly (n = 1) or repeatedly postponed interview (n = 13). Fifty follow-up interviews were completed, a response rate of 78% among 64 participants contacted. The overall response rate in those approached was 64% (0.82 * 0.78). Costs for 108 interviews were 45 person-days and Dollars A19,000 (32% = travel/associated costs). Costs for 50 follow-up interviews were 60 person-days and Dollars A25,500 (39% = travel/associated costs). Such follow-up studies in these settings could be complemented by retrospective case - control approaches and by using proxy respondents to increase study efficiency.

A recent rise in cannabis use in Indigenous communities in northern Australia may have compounded existing patterns of other substance use. This paper describes these patterns in Arnhem Land in the 'Top End' of the Northern Territory (NT). Economic impacts of the cannabis trade are also described. In a descriptive cross-sectional study, random samples included 336 people (169 males, 167 females) aged 13 - 36 years. Consensus classification of lifetime and current use of cannabis, alcohol, tobacco, kava, inhalants (petrol) and other drugs was derived based on health workers' proxy assessments. A sample (n = 180, aged 13 - 36) was recruited opportunistically for interview. Lifetime cannabis users among those interviewed (n = 131, 81 males, 50 females) described their current cannabis use, usual quantities purchased and consumed, frequency and duration of cannabis use and other substance use. In the random samples, 69% (63 - 75%) of males and 26% (20 - 31%) of females were lifetime cannabis users (OR = 7.4, 4.5 - 12.1, p < 0.001). The proportion of males currently using cannabis was 67% (60 - 73%) while the proportion of females currently using cannabis was 22% (16 - 27%) (OR = 7.9, 4.8 - 13.1, p < 0.001). Current cannabis users were more likely than non-users to be also using alcohol (OR = 10.4, 4.7 - 23.3, p < 0.001), tobacco (OR = 19.0, 7.9 - 45.8, p < 0.001) and to have sniffed petrol (OR = 9.1, 4.6 - 18.0, p < 0.001) but were less likely to be using kava (OR = 0.4, 0.2 - 0.9, p < 0.001). Among those interviewed, higher tobacco consumption in current users and greater alcohol use in lifetime users was associated with increased cannabis use. Action is required to reduce cannabis use, especially in combination with other substances.

The health consequences of kava abuse in Arnhem Land Aboriginal populations in the Northern Territory (NT) and the persistence of an illegal kava trade with its associated social harms have been a cause for concern for 20 years. Despite these concerns, some Arnhem Land groups seek to continue using kava and to control its sale, distribution and the profits from the enterprise. In response, policy makers in the NT have embraced principles of harm reduction and created regulatory mechanisms to address broader public concerns and to support local management of kava supply while reinforcing control over the consequences of its use. This paper describes the kava regulatory system now being implemented in the NT which features kava management plans developed in consultation between Aboriginal communities and licensing authorities. It complements the earlier Harm Reduction Digest 9 by McDonald & Jowitt which looked at Kava in the South Pacific.

The objective of the study was to describe parameters for use in monitoring health, social and economic effects of kava use in Arnhem Land Aboriginal communities in the Northern Territory (NT). Kava has been used mainly in eight communities (population > 200), and in smaller associated homeland areas since 1982 with a total population of approximately 6800, using cross-sectional description and comparison using data from three kava-using communities. Interview data combined with health worker assessments were compiled using: (1) a sample (n=136) aged 16-34 years in one community in 2001-02; (2) a sample (n=101) aged 16 years and over in 2000 where physical assessments and biochemical and haematological data were also collected; (3) participant-observation in one community (133 people aged 18 years and over) during 1989-91. Kava, supplied illegally, was still being used in Arnhem Land in 2001-02. In 2000 dermopathy characteristic of heavy use, abnormally low body mass index (BMI), low blood lymphocytes and abnormally high gamma-glutamyl transferase (GGT) occurred more frequently with increased kava use. These acute effects emerge at average consumption levels of from 310-440 g/week of kava powder. When kava users in one community began to consume it at an average of 240-425 g/week from mid-1990, 19% of available cash resources were spent on kava with 11% of cash resources leaving the local community economy. The proportion of men drinking kava reached 70% and women 62% from mid-1990, with 20% of the population spending unprecedented amounts of time (14 + hours/week) in activities where kava was consumed. These parameters may be useful to monitor kava's adverse health, social and economic effects. Their association with increased kava use suggests that approaches to minimizing harm from its abuse may begin fruitfully with controlling supply.

The objective of this study was to describe patterns of substance use among remote Aboriginal community populations. The setting was the eastern Arnhem Land ('Miwatj') region of the Northern Territory's (NT) 'Top End', with a population of 4217 Aboriginal people over 15 years of age using a cross-sectional description and comparison. Sample 1 (n = 689) from the region used data from health-worker consensus classification of kava, alcohol, tobacco, petrol and cannabis use. Sample 2 (n = 101) from one community used self-reported use, age at commencement, duration, amounts consumed and expenditure. In 1999 (sample 1), 46% of males and 18% of females were kava users, alcohol: 53% males, 12% females, tobacco: 68% males, 65% females, and cannabis: 31% males, 8% females. Less than 5% sniffed petrol. In one community in 2000, 39% males and 20% females reported using cannabis during the previous month. In this community between 1999 and 2000, the proportion of current kava users among men declined (77-52%, p = 0.015) with a tendency in women for a decrease in the proportion of tobacco users (87-69%, p = 0.096). The increase in the proportion of cannabis users in men (21-39%, p = 0.068) was not statistically significant. However, in women the increase was significant (0-20%, p = 0.013). Gross expenditure on tobacco and kava were similar in 2000: both greater than cannabis and alcohol. Median years used ranged from 4 years for cannabis and 20 years for tobacco. The data supported anecdotes of a recent rise in cannabis use, especially in women. Kava use declined in men. Tobacco use patterns in women may have been changing. Average per capita consumption of alcohol was low compared with other 'Top End' areas. Such varied and dynamic substance use patterns pose challenges for research and policy.
