This paper critically analyses a statement by Australia's National Health and Medical Research Council (NHMRC) on e‐cigarettes in May 2022 that will be used to guide national policy. We reviewed the evidence and the conclusions drawn in the NHMRC Statement. In our view, the Statement is not a balanced reflection of the benefits and risks of vaping because it exaggerates the risks of vaping and fails to compare them to the far greater risks of smoking; it uncritically accepts evidence of harms from e‐cigarettes while adopting a highly sceptical attitude towards evidence of their benefits; it incorrectly claims that the association between adolescent vaping and subsequent smoking is causal; and it understates the evidence of the benefits of e‐cigarettes in assisting smokers to quit. The Statement dismisses the evidence that vaping is probably already having a positive net public health effect and misapplies the precautionary principle. Several sources of evidence supporting our assessment were published after the NHMRC Statement's publication and are also referenced. The NHMRC Statement on e‐cigarettes does not present a balanced assessment of the available scientific literature and fails to meet the standard expected of a leading national scientific body.

Background and Aims: The pathways model is a highly cited etiological model of problem gambling. In the past two decades, a number of studies have found support for the model's utility in classifying gambling subtypes. The aims of this paper were to refine empirically the model subtypes and to revise and update the model based on those findings. Design and Measurement: Observational study using data collected from treatment‐seeking problem gamblers using the Problem Gambling Severity Index (PGSI) and the Gambling Pathways Questionnaire (GPQ). Setting: Treatment clinics in Canada, Australia and the United States. Participants: A convenience sample of 1168 treatment‐seeking problem gamblers, aged 18 years or older. Findings Empirically validated risk factors were analyzed using latent class analyses, identifying a three‐class solution as the best‐fitting model. Those in the largest class (class 1: 44.3%, n = 517) reported the lowest levels of all etiological risk factors. Participants in class 2 (39.5%, n = 461) reported the highest rates of anxiety and depression, both before and after gambling became a problem, as well as childhood maltreatment, and a high level of gambling for stress‐coping. Those in class 3 (16.3%, n = 190) reported high levels of impulsivity; risk‐taking, including sexual risk‐taking; antisocial traits; and coping to provide meaning in life and to alleviate stress. Conclusions: The revised pathways model of problem gambling includes three classes of gamblers similar to the three subtypes in the original pathways model, but class 3 in the revised pathways model is distinct from class 2, showing higher levels of risk‐taking and antisocial traits and gambling motivated by a desire for meaning/purpose and/or to alleviate stress. Class 2 in the revised pathways model demonstrates high levels of childhood maltreatment as well as gambling for stress‐coping. [ABSTRACT FROM AUTHOR]

Aims: The United Kingdom and Australia have developed highly divergent policy responses to electronic nicotine delivery systems (ENDS). To understand the historical origins of these differences, we describe the history of tobacco control in each country and the key roles played in setting ENDS policy in its early stages by public health regulations and policy networks, anti‐smoking organizations, 'vaper' activist networks and advocates of harm reduction policies towards injecting drug use. Methods: We analysed key government reports, policy statements from public health bodies and non‐government organizations (e.g. cancer councils and medical organizations) on ENDS; submissions to an Australian parliamentary inquiry; media coverage of policy debates in medical journals; and the history of tobacco control policy in Australia and England. Key discourses about ENDS were identified for each country. These were compared across countries during a multi‐day face‐to‐face meeting, where consensus was reached on the key commonalities and divergences in historical approaches to nicotine policy. This paper focuses on England, as different policy responses were apparent in constituent countries of the United Kingdom, and Scotland in particular. Results: Policymakers in Australia and England differ markedly in the priority that they have given to using ENDS to promote smoking cessation or restricting smokers' access to prevent uptake among young people. In understanding the origins of these divergent responses, we identified the following key differences between the two countries' approaches to nicotine regulation: an influential scientific network that favoured nicotine harm reduction in the United Kingdom and the absence of such a network in Australia; the success of different types of health activism both in England and in Europe in opposing more restrictive policies; and the greater influence on policy in England of the field of illicit drug harm reduction. Conclusions: An understanding of the different policy responses to electronic nicotine delivery systems (ENDS) in England and Australia requires an appreciation of how actors within the different policy structures, scientific networks and activist organizations in each country and region have interpreted the evidence and the priority that policymakers have given to the competing goals of preventing adolescent uptake and encouraging smokers to use ENDS to quit smoking.

Aims: This paper presents updated prevalence estimates of awareness, ever‐use, and current use of nicotine vaping products (NVPs) from 14 International Tobacco Control Policy Evaluation Project (ITC Project) countries that have varying regulations governing NVP sales and marketing. Design, Setting, Participants and Measurements: A cross‐sectional analysis of adult (≥ 18 years) current smokers and ex‐smokers from 14 countries participating in the ITC Project. Data from the most recent survey questionnaire for each country were included, which spanned the period 2013–17. Countries were categorized into four groups based on regulations governing NVP sales and marketing (allowable or not), and level of enforcement (strict or weak where NVPs are not permitted to be sold): (1) most restrictive policies (MRPs), not legal to be sold or marketed with strict enforcement: Australia, Brazil, Uruguay; (2) restrictive policies (RPs), not approved for sale or marketing with weak enforcement: Canada, Malaysia, Mexico, New Zealand; (3) less restrictive policies (LRPs), legal to be sold and marketed with regulations: England, the Netherlands, Republic of Korea, United States; and (4) no regulatory policies (NRPs), Bangladesh, China, Zambia. Countries were also grouped by World Bank Income Classifications. Country‐specific weighted logistic regression models estimated adjusted NVP prevalence estimates for: awareness, ever/current use, and frequency of use (daily versus non‐daily). Findings NVP awareness and use were lowest in NRP countries. Generally, ever‐ and current use of NVPs were lower in MRP countries (ever‐use = 7.1–48.9%; current use = 0.3–3.5%) relative to LRP countries (ever‐use = 38.9–66.6%; current use = 5.5–17.2%) and RP countries (ever‐use = 10.0–62.4%; current use = 1.4–15.5%). NVP use was highest among high‐income countries, followed by upper–middle‐income countries, and then by lower–middle‐income countries. Conclusions: With a few exceptions, awareness and use of nicotine vaping products varied by the strength of national regulations governing nicotine vaping product sales/marketing, and by country income. In countries with no regulatory policies, use rates were very low, suggesting that there was little availability, marketing and/or interest in nicotine vaping products in these countries where smoking populations are predominantly poorer. The higher awareness and use of nicotine vaping products in high income countries with moderately (e.g. Canada, New Zealand) and less (e.g. England, United States) restrictive policies, is likely due to the greater availability and affordability of nicotine vaping products.

Abstract: Background and aims: The prevailing ‘evidence‐based policy’ paradigm emphasizes a technical–rational relationship between alcohol and drug research evidence and subsequent policy action. However, policy process theories do not start with this premise, and hence provide an opportunity to consider anew the ways in which evidence, research and other types of knowledge impact upon policy. This paper presents a case study, the police deployment of drug detection dogs, to highlight how two prominent policy theories [the Advocacy Coalition Framework (ACF) and the Multiple Streams (MS) approach] explicate the relationship between evidence and policy. Methods: The two theories were interrogated with reference to their descriptions and framings of evidence, research and other types of knowledge. The case study methodology was employed to extract data concerned with evidence and other types of knowledge from a previous detailed historical account and analysis of drug detection dogs in one Australian state (New South Wales). Different types of knowledge employed across the case study were identified and coded, and then analysed with reference to each theory. A detailed analysis of one key ‘evidence event’ within the case study was also undertaken. Results: Five types of knowledge were apparent in the case study: quantitative program data; practitioner knowledge; legal knowledge; academic research; and lay knowledge. The ACF highlights how these various types of knowledge are only influential inasmuch as they provide the opportunity to alter the beliefs of decision‐makers. The MS highlights how multiple types of knowledge may or may not form part of the strategy of policy entrepreneurs to forge the confluence of problems, solutions and politics. Conclusions: Neither the Advocacy Coalition Framework nor the Multiple Streams approach presents an uncomplicated linear relationship between evidence and policy action, nor do they preference any one type of knowledge. The implications for research and practice include the contestation of evidence through beliefs (Advocacy Coalition Framework), the importance of venues for debate (Advocacy Coalition Framework), the way in which data and indicators are transformed into problem specification (Multiple Streams) and the importance of the policy (‘alternatives’) stream (Multiple Streams).

Abstract: Established in 2006, the Centre for Alcohol Policy Research (CAPR) is Australia's only research centre with a primary focus on alcohol policy. CAPR has four main areas of research: alcohol policy impacts; alcohol policy formation and regulatory processes involved in implementing alcohol policies; patterns and trends in drinking and alcohol problems in the population; and the influence of drinking norms, cultural practices and social contexts, particularly in interaction with alcohol policies. In this paper, we give examples of key publications in each area. During the past decade, the number of staff employed at CAPR has increased steadily and now hovers at approximately 10. CAPR has supported the development of independent researchers who collaborate on a number of international projects, such as the Alcohol's Harm to Others study which is now replicated in approximately 30 countries. CAPR receives core funding from the Foundation for Alcohol Research and Education, and staff have been highly successful in securing additional competitive research funding. In 2016, CAPR moved to a new institutional setting at La Trobe University and celebrated 10 years of operation. [ABSTRACT FROM AUTHOR]

Background and aims Prohibitions on producing, distributing and selling cannabis are loosening in various jurisdictions around the world. This paper describes the diversification of cannabis supply laws and discusses the challenges to and opportunities for learning from these changes. Methods We document changes in cannabis supply laws that de jure legalized cannabis production for medical and/or non-medical purposes (excluding industrial hemp) in Australasia, Europe, North America and South America. We also highlight challenges to evaluating these legal changes based on our experiences studying cannabis laws and policies in the United States. Findings As of August 2016, two countries have passed laws to legalize large-scale cannabis production for non-medical purposes at the national (Uruguay) or subnational level (four US states). At least nine other countries legally allow (or will soon allow) cannabis to be supplied for medicinal purposes. Most of the changes in cannabis supply laws have occurred since 2010. The data available in most countries are inadequate for rigorously evaluating the changes in cannabis supply laws. Conclusion The evidence base for assessing changes in cannabis supply laws remains weak. Efforts should focus upon collecting information about quantities consumed and market transactions as well as validating self-report surveys. [ABSTRACT FROM AUTHOR]

Background and aims Following calls for restrictions and bans on alcohol advertising, and in light of the tobacco industry's challenge to Australia's tobacco plain packaging measure, a tobacco control measure finding support in the World Health Organization (WHO) Framework Convention on Tobacco Control, this paper considers what role, if any, an international alcohol marketing code might have in preventing or reducing the risk of challenges to domestic alcohol marketing restrictions under trade rules. Methods Narrative review of international trade and health instruments and international trade court judgements regarding alcohol products and marketing restrictions. Findings The experience of European trade courts in the litigation of similar measures suggests that World Trade Organization rules have sufficient flexibility to support the implementation of alcohol marketing restrictions. However, the experience also highlights the possibility that public health measures have disproportionate and unjustifiable trade effects and that the ability of a public health measure to withstand a challenge under trade rules will turn on its particular design and implementation. Conclusion Measures implemented pursuant to international public health instruments are not immune to trade law challenges. Close collaboration between health policymakers, trade officials and lawyers, from as early as the research stage in the development of a measure to ensure a robust evidence base, will ensure the best chance of regulatory survival for an international marketing code.

ABSTRACT Aims The aim of this paper is to provide a critical overview of the development and current status of gambling in Australia. Methods The paper examines the history and current status of gambling in Australia with a particular focus on the prevalence of problem gambling in the community and developments in policy and treatment services. Results The paper highlights the contradictory role of State governments as both providers of treatment services as well as agents for the liberalization for gambling. It also shows how the notion of 'addiction' is conceptualized in Australian research and treatment services, including the preference for harm-based and public health approaches. Such perspectives view problem gambling as having multiple pathways and determinants that extend beyond the pathology of individuals. Conclusions Gambling in Australia provides a curious paradox. Highly liberalized State government policies that allow the proliferation of high intensity gambling coexist with extensive policy, regulation and research designed to address the negative impact of gambling on the Australian community.

Background and aims Codeine is the most commonly used opioid in the world, and is available over the counter (OTC) in many countries, including Australia. Several countries are reconsidering codeine's OTC status due to concerns over addiction and misuse, with serious morbidity and mortality being reported. Australia's Therapeutic Goods Administration restricted codeine containing analgesics to 'Pharmacist Only' in 2010, and has recently been considering further up-scheduling to make codeine 'Prescription Only'. This paper estimated Australian trends of codeine misuse over the past 12 years, and examined whether trends changed following previous rescheduling efforts in 2010. Design A retrospective review of calls regarding codeine misuse made to the New South Wales Poisons Information Centre (NSWPIC, Australia's largest poisons centre), 2004-15. Joinpoint software was used to quantify the average annual change in calls, and whether there was a significant change in trend at any time, including following rescheduling. Setting Australia. Participants Four hundred patients about whom a call was made to the NSWPIC. Measures Calls per year, patient age, gender, tablets taken per day, formulation used, symptom disposition. Findings The NSWPIC database contained 400 cases of codeine combination analgesic misuse from 2004 to 2015. Joinpoint analysis showed that the frequency of cases increased significantly from 2004 to 2015, with an average annual percentage change (AAPC) of 19.5% [95% confidence interval (CI) = 13.8-25.5% P < 0.0001] for paracetamol/codeine and 17.9% (95% CI = 7.9-28.9%, P < 0.01) for ibuprofen/codeine. No significant change in trend was seen at any time, including following 2010 rescheduling. The median age of patients was 34 and 27 years for paracetamol/codeine and ibuprofen/codeine cases, respectively. Gender distribution was approximately equal. Clinical features reported were consistent with codeine, paracetamol and ibuprofen toxicity. Conclusions Misuse of codeine combination products appears to be increasing in Australia. Limited rescheduling in 2010 failed to curb this increase. [ABSTRACT FROM AUTHOR]

ABSTRACT Aim It has been proposed that alcohol industry 'social aspects/public relations' organizations (SAPROs) serve the agenda of lending credibility to industry claims of corporate responsibility while promoting ineffective industry-friendly interventions (such as school-based education or TV advertising campaigns) and creating doubt about interventions which have a strong evidence base (such as higher taxes on alcoholic beverages). This paper investigated whether submissions to Australia's National Preventative Health Taskforce (NPHT) from alcohol industry bodies regarding the Australian SAPRO, Drinkwise, have used this organization to demonstrate corporate responsibility while promoting industry-friendly interventions. Method Submissions to the Australian National Preventative Health Taskforce (NPHT) discussion paper Australia, the healthiest country by 2020 ( n = 375) were examined to identify those with primary alcohol content. A thematic analysis of the resulting 33 submissions was conducted to determine which organization, institution or individual discussed Drinkwise. Setting Australia. Findings Nine of the 33 submissions discussed Drinkwise; all were submitted by the alcohol industry or its affiliates. Every industry submission referred to Drinkwise either as providing evidence of social responsibility or by suggesting the industry-friendly actions of Drinkwise as alternatives to those recommended by the NPHT report. Conclusions Drinkwise has been used by the alcohol industry to create an impression of social responsibility while promoting interventions that maintain profits and campaigning against effective interventions such as higher taxes on alcohol.

Background and Aims Alcohol consumption is an avoidable risk factor for morbidity and mortality. Studies have examined relative risks and outcomes of alcohol-related harms in Australia at discrete times, limiting the ability to examine changes across time. This paper examined alcohol consumption and its contribution to deaths, illness and injury at two time-points, 2001 and 2010. Design Alcohol consumption was modelled based on the 2001 and 2010 National Drug Strategy Household Survey, upshifted to reflect alcohol sales data. Setting All data reported are from Australian sources. Measurements Based on relative risk estimates obtained from meta-analysis, alcohol-attributable fractions were estimated for 42 disease and injury categories in 2001 and 2010 separately for conditions that were not 100% alcohol-attributable. Deaths and hospital separations attributable to alcohol were calculated in 2001 and 2010. Findings There was a relatively stable per capita consumption of alcohol across time, with males reporting higher levels of consumption compared with females. While there were increases in the number of abstainers from alcohol across time, the proportion of heavy alcohol consumers also increased. This corresponded with an observed increase in alcohol-attributable burden. For example, alcohol-attributable deaths increased from 4957 [95% confidence interval (CI) = 2867-8770] to 5610 (95% CI = 3398-9408) during the study period. Conclusion The findings demonstrate that there has been an increase in alcohol-attributable harms between 2001 and 2010 in Australia without a corresponding increase in per capita consumption.

A correction to a paper printed in a prior issue is presented, written by Berridge et al., which discusses policy around electronic nicotine delivery systems.

This paper is a summary of some illuminating comments made by the author when invited to discuss some of the above papers in the area of liquor licensing and availability. Prior to his appointment as the Director I and Government Printer of State Print in South Australia, the author had been the first Director of Liquor Licensing in Western Australia. In that capacity he was responsible for undertaking a major review of the Liquor Act in Western Australia and in implementing a new administrative structure. He was subsequently appointed as the Chief Executive Officer of the Western Australian Totalisator Agency Board (which is responsible for off-course betting on horse and greyhound racing) before returning to South Australia. The author's experience of reviewing liquor licensing legislation in both South Australia and Western Australia, land his administration of a licensing authority provides him, in the Editors' view, with unique insights into the working of governments and the formulation of policy in this area. His paper is presented here in the form in which it was given at the conference. [ABSTRACT FROM AUTHOR]

This paper puts the role of research into perspective in the policy-making context. It points out that there are differing 'policy' goals of government and the use of research might be vital for one element, e.g. health policy, but of lesser significance in, say, international policy. The paper then goes on to describe case studies of where research has had a major impact on government decision making in Australia in the past 2 years, notably in the area of proposed changes to the marketing and sale of alcoholic beverages.

In 1990, a small research project costing about Aus. $4500 conducted in a Perth shopping centre directly influenced the development of a national policy within 4 months of its completion. The policy in question is a recommendation by Australia's Ministerial Council on Drag Strategy that all alcoholic beverage containers should carry labels indicating the number of 'standard drinks' they contain. The purpose of this paper is to describe the events leading up to so unusual an event with a view to discerning what factors may have been critical for its occurrence. The paper attempts to analyse the nature of the interactions between the research team and the policy makers. It is argued that the critical factors included there being a favourable policy climate created by the National Campaign Against Drag Abuse, the support of influential public servants and, in turn, politicians, the consultative process which lead to the study's design and the manner in which the findings were disseminated.

Aims This paper examines the strategies and arguments used by segments of the alcohol industry to delay the introduction of mandatory health warning labels on alcohol containers in Australia. These strategies are compared with those used by the tobacco industry to delay the introduction of warning labels for cigarettes. Methods Submissions made by members of the alcohol industry to the Australian Government's review of labelling and Parliamentary Inquiry into Fetal Alcohol Spectrum Disorders were analysed. Results Segments of the alcohol industry have delayed the introduction of mandatory alcohol health warning labels in Australia by questioning the rationale and evidence base for labels; arguing that they will cause damage to public health and the economy; lobbying and seeking to influence government and political representatives including through monetary donations; and introducing its own voluntary labelling scheme. The arguments made by these organizations against the introduction of mandatory health warning labels for alcohol are flawed and their empirical basis is limited. Conclusion The Australian Government has delayed the introduction of mandatory alcohol health warning labels in Australia by 2 years, until at least December 2013. The campaigning of some parts of the alcohol industry appears to have been instrumental in this decision. [ABSTRACT FROM AUTHOR]

ABSTRACT Aim This paper examines how smokers' beliefs about 'light/mild' cigarettes in Australia, Canada and the United Kingdom were affected by the removal of misleading 'light/mild' terms from packs. Design, setting and participants The data come from the first seven waves (2002-09) of the International Tobacco Control Policy Evaluation (ITC) Four-Country Survey, an annual cohort telephone survey of adult smokers in Canada, the United States, the United Kingdom and Australia (21 613 individual cases). 'Light' and 'mild' descriptors were removed in 2003 in the United Kingdom, in 2006 in Australia and in 2007 in Canada. We compare beliefs about 'light' cigarettes both before and after the bans, with those of smokers in the United States serving as the control condition. Measures Smokers' beliefs about 'light' cigarettes were assessed using a set of statements rated on a five-point 'agree'-'disagree' scale. Findings The proportions of respondents reporting misperceptions about light cigarettes declined between 2002 and 2009 in all four countries. There were marked temporary reductions in reported misperceptions in the United Kingdom and Australia, but not in Canada, following the removal of 'light/mild' descriptors. Conclusions Removal of 'light/mild' descriptors and tar, nicotine and carbon monoxide yield information from cigarette packs is insufficient to effectively eliminate false beliefs. The combination of alternative descriptors and design features that produce differences in taste strength and harshness, independent of actual intakes, are sufficient to produce or sustain the same misbeliefs.

This paper models the predicted impact of tobacco price increases proposed in the United States and Australia during 2009 on smoking prevalence in 2010 while taking account of the effects of financial stress among smokers on cessation rates. Two models of smoking prevalence were developed for each country. In model 1, prevalence rates were determined by price elasticity estimates. In model 2 price elasticity was moderated by financial stress. Each model was used to estimate smoking prevalence in 2010 in Australia and the United States. Proposed price increases resulted in a 1.89% and 7.84% decrease in smoking participation among low socio-economic status (SES) groups in the United States and Australia, respectively. Model 1 overestimated the number of individuals expected to quit in both the United States (0.13% of smokers) and Australia (0.36% of smokers) by failing to take account of the differential effects of the tax on financially stressed smokers. The proportion of low-income smokers under financial stress increased in both countries in 2010 (by 1.06% in the United States and 3.75% in Australia). The inclusion of financial stress when modelling the impact of price on smoking prevalence suggests that the population health returns of increased cigarette price will diminish over time. As it is likely that the proportion of low-income smokers under financial stress will also increase in 2010, future population-based approaches to reducing smoking will need to address this factor.

Aim Much information regarding predictors of illicit drug initiation and cessation is drawn from cross-sectional data. This paper aims to determine the longitudinal changes in factors associated with initiation and cessation of illicit drugs by young Australian women over a 3-year period. Participants The sample was the cohort of young women moving from their mid- to late 20s, completing the Australian Longitudinal Study on Women's Health (ALSWH) survey in 2000 and 2003, who were either ‘new’ users or ‘quitters’ at the 2003 survey. Measurements Crude and multivariate associations between changes in predictor variables and the probability of illicit drug initiation or cessation were evaluated. Variables significant in univariate analyses were used to create multivariable logistic regression models which predicted initiation and cessation of illicit drugs. Findings All categories of smokers, except ex-smokers and those who adopted and quit smoking between surveys, were less likely to cease the use of illicit drugs. Women who became pregnant were more likely to cease illicit drug use. Women who continued to drink at levels described as long-/short-term risk and women who suffered continuing emotional abuse were less likely to cease use of illicit drugs. Conclusions Longitudinal studies that examine factors associated with illicit drug initiation are best conducted in a cohort aged in their late teens to early 20s. Following the current cohort into their late 30s may further explain predictors of illicit drug cessation. [ABSTRACT FROM AUTHOR]

Aims This paper examines differences between early- and late-onset injection drug users (12–16 years versus 17–24 years) in terms of the antecedents and circumstances of first injection. Design Cross-sectional retrospective design, using logistic regression. Setting Australia: Sydney, Brisbane, rural New South Wales. Participants A total of 336 injection drug users aged 16–25 years at the time of interview. Measurements Independent variables included family injection drug use, homelessness and other demographic variables, drugs used prior to the first injection, length of pre-injection drug career, behaviours at time of first injection (e.g. drug injected, reasons/motives for the first injection, risk behaviours). Findings Early-onset injection was associated independently with: having a family who injected drugs, having left school early, an unreliable source of income, a short pre-injection drug career, planning of the first injection, reliance on others for administration of the first injection and denial that experimentation was the motive for the first injection. In bivariate analysis, early-onset injection was associated further with: homelessness, being an Indigenous Australian, omission of use of certain pre-injection drugs, group presence at first injection, reliance on others for acquisition of the first needle and syringe and having injected the first time because an injection was offered. Conclusions The research shows that early-onset, compared with late-onset injectors, are more likely to have an immediate family who inject drugs and other problematic beginnings in early life. They have an accelerated transition to injection, and differences in autonomy and motivation at first injection. These characteristics may make them more vulnerable to risk taking.

To conduct an empirical investigation of the efficacy of law enforcement in reducing heroin supply in Australia. Specifically, this paper addresses the question of whether heroin purity levels in the Australian Capital Territory (ACT) could be predicted by heroin seizures at the national level by the Australian Federal Police (AFP) in the preceding year. We considered two forms of evidence. First, a Bayesian Markov Chain Monte Carlo (MCMC) change-point model was used to discover (a) if there was a substantial increase in heroin seizures by the AFP, (b) when the increase began and (c) whether it occurred after increased funding to the Australian Federal Police for the purpose of drug law enforcement. Second, standard time-series methods were used to ascertain whether fluctuations in heroin seizure weights or the frequency of large-scale seizures after the aforementioned changes in seizure levels predicted fluctuations in heroin purity levels in the ACT after autocorrelation had been removed from the purity series. A Bayesian MCMC change-point model supported the hypothesis that heroin seizures rapidly increased about a year before the estimated decline in heroin purity and after the increased funding of AFP. The autoregression models suggested that 10–20% of the variance in the residuals of the heroin purity series was predicted by appropriately lagged residuals of the seizure-number and log-weight series, after autocorrelation had been removed. The overall results are consistent with the hypothesis that large-scale heroin seizures by the AFP reduce street-level heroin supply a year or so later, although the short-term dynamics suggest an ‘opponent’ response to residual fluctuations in seizures. To our knowledge, this is first time a connection has been identified between large-scale heroin seizures and street-level supply. [ABSTRACT FROM AUTHOR]

This paper analyses a partnership between an addiction agency and the drinks industry in Australia, with special reference to concerns held by public health advocates for such projects.Public health anxieties regarding collaboration between the drugs sector and the drinks industry are identified. A projected partnership between the Alcohol and Drug Foundation—Queensland (ADFQ) and the liquor industry in Australia is reviewed. The partnership involves the creation of a new organization, Alcohol Education Australia Ltd. (AEA), which states as its aim the education of consumers in responsible drinking. In order to assess the impact of the partnership an examination is undertaken of the AEA's stated mission and objectives, of relevant policy development by ADFQ and of ADFQ's intervention in support of an alcohol manufacturer which was putting a case to a licensing authority.The results indicate the partnership advances the interests of the drinks industry rather than public health. The mission and objectives of Alcohol Education Australia Ltd subordinate public health goals to industry aims and the host organization, the ADFQ, has changed its policy and practice to accommodate the drinks industry.The partnership between the ADFQ and the drinks industry indicates the difficulty faced by addiction organizations in maintaining an uncompromising public health orientation when in partnership with the alcohol industry.

Periodic public concern about heroin use has been a major driver of Australian drug policy in the four decades since heroin use was first reported. The number of heroin-dependent people in Australia has increased from several hundreds in the late 1960s to around 100 000 by the end of the 1990s. In this paper I do the following: (1) describe collaborative research on heroin dependence that was undertaken between 1991 and 2001 by researchers at the National Drug and Alcohol Research Centre; (2) discuss the contribution that this research may have made to the formulation of policies towards the treatment of heroin dependence during a period when the policy debate crystallized around the issue of whether or not Australia should conduct a controlled trial of heroin prescription; and (3) reflect on the relationships between research and policy-making in the addictions field, specifically on the roles of investigator-initiated and commissioned research, the interface between researchers, funders and policy-makers; and the need to be realistic about the likely impact of research on policy and practice.

Aims. This paper explores the relationship between alcohol sales and assault in New South Wales (NSW), Australia. Design. The design was a cross-sectional analysis of the relationship between alcohol sales and assault, taking into account spatial autocorrelation. Setting. The analyses were carried out separately on data from metropolitan Sydney and country NSW. Participants. The unit of analysis was local government areas (178 in NSW). Measurements. The dependent variable was assault rates. The independent variables were overall alcohol sales and sales disaggregated by alcohol and outlet type and relevant demographic and socio-economic factors. Findings. Multiple regression analyses revealed a significant relationship between overall alcohol sales in an area and its incidence of assault for both Sydney and country NSW. There were few effects of outlet or alcohol type for Sydney, but the effect of alcohol sales from hotels and off-licences accounted for most of the alcohol-assault relationship for country NSW. Conclusions. Although the current research cannot exclude an opportunity account of the role of alcohol in assault, the results are entirely consistent with alcohol consumption as a causal agent.

The article presents a response to the commentary by J. P. Caulkins, P. Reuter and M. Smithson on the study by Evan Wood and colleagues which was published in the paper "Changes in Canadian heroin supply coinciding with the Australian heroin shortage," in a 2006 issue. The findings of the study countered the main argument by those who believe that the Australian heroin shortage was due to local factors, such as law enforcement activities, by showing that similar changes happened in a heroin market in another country also supplied by Burma.

In this article the author discusses a research paper which analysis the effectiveness of implementing smoke-free policies on teen smoking in Australia using representative triennial state wide surveys. It is given that the paper was significantly used by the by the International Agency for Research on Cancer (IARC) as an evidence for analyzing the effectiveness of smoke-free policies. He also reflects on the comparison between home smoking restrictions and work place policies.

The article comments on the paper "Changes in Canadian heroin supply coinciding with the Australian heroin shortage," by E. Wood and colleagues in a 2006 issue. The paper stated that the naxolone utilization statistics were restricted to fiscal-year summaries. However, it is not clear whether similar restrictions have been applied on all the other indicators. Moreover, before-after comparisons cannot be used to effectively examine time-series data.

The authors present their thoughts on the study "The Effect of Alcohol Outlets, Sales and Trading Hours on Alcohol-Related Injuries Presenting at Emergency Departments in Perth, Australia From 2002 to 2010" by M. Hobday et al. from the issue. They suggest that the paper's findings are symptomatic of ongoing problems in alcohol policy analysis.

In this article, the authors discuss the study by A. Agrawal and colleagues concerning the impact of proposed revisions on alcohol use disorders (AUD) diagnosis. The authors state that the paper has capitalized on epidemiological data which assess the changes effect on estimated population prevalence of AUDs. The authors say that the development of intervention planning and development of needs assessment were the purpose of prevalence estimation.

In this article the author reflects on the sustainable expansion of harm reduction services for drug users in the U.S. He notes that one of the purposes of their paper is asking if it should occur within a separate health care system for drug users or within the mainstream health care system. He cites the concept of harm reduction in the European Union (EU), France, and Australia and states that continued cross-national research on the issue may be helpful.

The article comments on the paper "Changes in Canadian heroin supply coinciding with the Australian heroin shortage," by E. Wood and colleagues in a 2006 issue. The approach used by Wood and colleagues as straightforward. However, for the higher frequency and longest series, frequency of daily heroin injection by Vancouver injecting drug users, they indicated only that there is a difference between pre- and post-2001. They failed to state whether 2001 is the optimum break point.
