Aims To evaluate how well people in the night-time economy can assess their own breath alcohol concentration (BrAC), in the context of a change in breath alcohol limits for driving. Methods We conducted a field study of 242 participants over 5 nights in the central business district of a university town in New Zealand. Participants completed a short survey, which included questions on their self-reported level of intoxication and the self-estimated BrAC. At the conclusion of the interview each participant was breath-tested. We compared actual and self-estimated BrAC using a scatter plot and multiple regression methods. Results The average BrAC error was 61.7 μg/l, meaning that on average participants overestimate their BrAC. Participants with a BrAC below 487 μg/l tended to overestimate their BrAC on average, and those with a BrAC above 487 μg/l tended to underestimate their BrAC on average. Regression results supported this observation, but also found that men who are not 'out on a typical night' overestimate their BrAC by more. Conclusions Drinkers in this naturalistic setting have little idea of their level of intoxication, as measured by BrAC. However, this uncertainty may be advantageous to public health outcomes, since if drinkers are uncertain about their level of intoxication relative to the legal limit, this may lead them to avoid drunk driving. Short Summary A field study of drinkers in the night-time economy of a New Zealand university town was conducted to evaluate how well drinkers can assess their breath alcohol concentration (BrAC). Drinkers in this setting inaccurately estimate their intoxication, and those with higher BrAC tended to underestimate their BrAC on average. [ABSTRACT FROM AUTHOR]

In den Jahren 2018-2020 wurden auf verschiedenen Betrieben in Nordrhein-Westfalen zu verschiedenen Terminen unterschiedliche Zwischenfrüchte mit unterschiedlicher Saattechnik und mit unterschiedlichen Arten der Bodenbearbeitung gesät. Dies geschah nach Wintergetreide und vor den folgenden Sommerungen: Sommergerste (Hordeum vulgare), Zuckerrüben (Beta vulgaris subsp. vulgaris convar.) und Mais (Zea mays). Ziel war es, die verschiedenen Verfahren zu vergleichen und ihre Eignung im Hinblick auf Etablierungssicherheit, Unkrautunterdrückung und Absterbeverhalten zu untersuchen. Wurde die Zwischenfruchtsaat zwei Wochen vor der Ernte in die Getreidebestände eingestreut, führte dies nur in einem von acht Versuchen zu einem guten Ergebnis. Ein gutes Ergebnis meint, dass die Zwischenfrucht andere Pflanzen ausreichend unterdrücken konnte. In den übrigen Versuchen lief die Zwischenfrucht nicht oder nur partiell auf. Wurde die Zwischenfrucht direkt nach der Saat in den Boden geschlitzt stieg die Erfolgsquote. In 50 % der Fälle entwickelte sich über den größten Teil der Parzellen ein gleichmäßiger, konkurrenzstarker Bestand, der Ausfallgetreide und Unkräuter unterdrückte und einen weiteren Unkrautauflauf bis zum Ende des Winters verhinderte. Zudem starben die Bestände über Winter ab. Für die Saat der nachfolgenden Sommerfrüchte war nur eine flache Saatbettbereitung erforderlich. In den Trockenjahren (2018 und 2019) war deutlich zu sehen, dass die Keimrate von Phacelia (Phacelia tanacetifolia) deutlich besser war als die von Leguminosen (Fabaceae), Sonnenblumen (Helianthus annuus), Buchweizen (Fagopyrum esculentum) oder einkeimblättrigen Pflanzen. Unter den feuchteren Bedingungen in 2020 konnte die starke Empfindlichkeit von Phacelia (Phacelia tanacetifolia) gegenüber Bodenverdichtungen beobachtet werden. In den Fahrgassen waren aber auch andere Pflanzen selten in der Lage, den Aufwuchs von unerwünschten Pflanzen, wie Ausfallgetreide, zu verhindern. Die frühen Saattermine (Juli bis Anfang August) bedingten, dass Phacelia, Lein (Linum usitatissimum) und Buchweizen, vor Winter reife Samen ausbildeten. So kam es in den nachfolgenden Sommerungen zum Auflauf von Pflanzen aus den ausgefallenen Zwischenfruchtsamen. Waren die Ergebnisse nicht zufriedenstellend, konnten bei diesem Verfahren (Saat direkt nach der Saat), eine schlechte Spreuverteilung, ungünstige Feuchteverhältnisse, Bodenverdichtungen oder Mäusefraß als Ursachen ausgemacht werden. Bei gleichem Saattermin aber mit vorheriger Bodenbearbeitung waren die Ergebnisse sehr eindeutig. In allen Fällen wurde die Keimung des Ausfallgetreides so stark angeregt, dass die Zwischenfrucht nicht mehr in der Lage war, das Ausfallgetreide ausreichend zu unterdrücken. Beim letzten Verfahren wurde das Ausfallgetreide zunächst durch eine zwei- bis dreimalige Bodenbearbeitung bekämpft. Die Saat der Zwischenfrucht erfolgte vier bis sechs Wochen nach der Ernte des Getreides. Die Etablierung war in allen Fällen kein Problem. Mäusefraß spielte keine Rolle. Allerdings liefen bei diesem Verfahren, gemeinsam mit der Zwischenfrucht, auch Acker-Fuchsschwanz (Alopecurus myosuroides Huds.) und Altraps (Brassica napus) auf. Diese Schlüsselunkräuter wurden, bei diesem Verfahren, nicht ausreichend unterdrückt.

Fossil fuel subsidies continue to be a considerable barrier to meeting the targets of the Paris Agreement. It is thus crucial to understand the political economy of fossil fuel subsidies and their reform. To understand these mechanisms in the developed world, we use a database of different types of fossil fuel subsidy reforms among Organisation for Economic Co-operation and Development (OECD) countries. We find evidence for four intertwined processes i) a market-power mechanism: higher market shares for renewables ease fossil fuel subsidy reforms, and ii) a policy mechanism: reforms reduce the levels of fossil fuel subsidies. Importantly, both effects are contingent on iii) a polity mechanism where institutional quality influences the feasibility and effectiveness of political reforms, and iv) a feedback mechanism where systemic lock-ins determine the effectiveness of market competition. Our results even suggest that reforms carried out by effective governments with low corruption control are associated with increasing subsidies per capita. Renewable energy support can however provide a leverage point to break path-dependencies in fossil fuel-based economies. This turns out to be more effective when coupled with improvements to institutional quality and the insulation of political processes from pro-subsidy interests., (© 2024. The Author(s).)

We analyze the development of biodiversity offsetting governance through a research-weaving approach. Here, we combine information from a systematized review of the literature and a qualitative analysis of the institutional developments in different world regions. Through this triangulation, we synthesize and map the different developmental streams of biodiversity offsetting governance around the globe over the last four decades. We find that there is a global mainstreaming of core principles such as avoidance, no-net-loss, and a mitigation hierarchy, as well as pooling and trading of offsets for unavoidable residual damages. Furthermore, we can observe an ongoing diversification of institutional designs and actors involved. Together this constitutes an emerging regime complex of biodiversity offsetting governance that comes with both a set of shared norms and a growing institutional complexity. While this may imply institutional innovation through diversification and policy experimentation, it also raises questions regarding the effectiveness of offsetting practices., (Copyright © 2022 The Authors.

Introduction and Aims: Past research indicates heavy episodic drinking (HED), trait aggression, male honour and conformity to masculine norms are risk factors for male barroom aggression (MBA) perpetration. However, little is known about the impact of these variables on experiences of MBA victimization. Further, data derived previously, particularly in relation to perpetration have come from relatively low-risk samples comprising university students, limiting the generalizability of findings to other, at-risk male groups. Thus, the present study assessed the impact of the aforementioned variables as well as personality constructs of impulsivity and narcissism on both the perpetration of and victimization from MBA among a high-risk sample sourced from male members of the Australian construction industry. Method: A purposive sample of Australian male construction workers aged 18 to 69 years ( n = 476, M age = 25.90, SD age = 9.44) completed individual interviews at their current place of employment or while training at various trade schools in Geelong and Melbourne, Victoria, Australia. Items related to past month HED, past year experiences of verbal and physical MBA (perpetration and victimization), trait aggression's four factors (physical, verbal, anger, hostility), impulsivity, narcissism, male honour and conformity to masculine norms. Results: Participants reported high levels of verbal (24.2%) and physical (21%) MBA perpetration and verbal (33.6%) and physical (31.1%) MBA victimization. Hierarchical binary logistic regression analyses identified HED as the strongest predictor of aggression involvement, while trait physical aggression, trait anger, narcissism and conformity to norms endorsing violence and a need to win were significantly and positively associated with MBA perpetration. Conclusions: The present study reinforces the key relationships between heavy drinking and aspects of personality and MBA, while also highlighting narcissism as a risk factor for barroom aggression perpetration. Indeed, personality profiles and HED appear to exert stronger influences on MBA perpetration than socially constructed masculinity factors, most of which were unrelated to aggression involvement in bars, clubs or pubs.

To preserve biodiversity and ecosystem services, company engagement is crucial. However, available data on manager views and perceptions regarding nature conservation in particular is rare. The presented survey data gives insights into current levels and forms of business commitments for nature conservation. The data contributes to understanding business attitudes towards voluntary conservation action and includes information about factors that influence their engagement. Moreover, the data informs about manager perceptions towards the concept of nature conservation credits and, as such, allows for an evaluation of a certified biodiversity and ecosystem services market. Importantly, the dataset contains essential company characteristics to put responses into greater context. The scope of the survey is limited to German companies from secondary and tertiary sectors. Companies were sampled through proportional stratified random sampling based on size and location. The data was collected through a self-administered online-survey, conducted in 2019. The database comprises responses of 747 companies that logged into the online system. The survey data were in part analysed through structural equation modelling for an investigation of factors that drive voluntary conservation commitments [1]. Related to this analysis, a subset of 618 companies is available that provided sufficiently completed questionnaires. Both datasets, i.e. the raw data as well as the first subset used for analysis, are hosted in the public repository Open Research Data of the Leibniz Centre for Agricultural Landscape Research (ZALF), Germany. The repository also stores all coding information as well as the questionnaire: https://www.doi.org/10.4228/ZALF.DK.149. The dataset can be used, for example, by researchers from the field of environmental business management and strategy., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships which have or could be perceived to have influenced the work reported in this article., (© 2020 Leibniz Centre for Agricultural Landscape Research (ZALF).)

The bioeconomy is currently being globally promoted as a sustainability avenue involving several societal actors. While the bioeconomy is broadly about the substitution of fossil resources with bio-based ones, three main (competing or complementary) bioeconomy visions are emerging in scientific literature: resource, biotechnology, and agroecology. The implementation of one or more of these visions into strategies implies changes to land use and thus ecosystem services delivery, with notable trade-offs. This review aims to explore the interdisciplinary space at the interface of these two concepts. We reviewed scientific publications explicitly referring to bioeconomy and ecosystem services in their title, abstract, or keywords, with 45 documents identified as relevant. The literature appeared to be emerging and fragmented but eight themes were discernible (in order of decreasing occurrence frequency in the literature): a. technical and economic feasibility of biomass extraction and use; b. potential and challenges of the bioeconomy; c. frameworks and tools; d. sustainability of bio-based processes, products, and services; e. environmental sustainability of the bioeconomy; f. governance of the bioeconomy; g. biosecurity; h. bioremediation. Approximately half of the documents aligned to a resource vision of the bioeconomy, with emphasis on biomass production. Agroecology and biotechnology visions were less frequently found, but multiple visions generally tended to occur in each document. The discussion highlights gaps in the current research on the topic and argues for communication between the ecosystem services and bioeconomy communities to forward both research areas in the context of sustainability science.

Background: Sharing anonymised ED data with community agencies to reduce alcohol-related injury and assaults has been found effective in the UK. This protocol document outlines the design of an Australian multi-site trial using shared, anonymised ED data to reduce alcohol-related harm., Design and Method: Nine hospitals will participate in a 36 month stepped-wedge cluster randomised trial. After a 9 month baseline period, EDs will be randomised in five groups, clustered on geographic proximity, to commence the intervention at 3 monthly intervals. 'Last-drinks' data regarding alcohol use in the preceding 12 h, typical alcohol consumption amount, and location of alcohol purchase and consumption, are to be prospectively collected by ED triage nurses and clinicians at all nine EDs as a part of standard clinical process. Brief information flyers will be delivered to all ED patients who self-report risky alcohol consumption. Public Health Interventions to be conducted are: (i) information sharing with venues (via letter), and (ii) with police and other community agencies, and (iii) the option for public release of 'Top 5' venue lists., Outcomes: Primary outcomes will be: (i) the number and proportion of ED attendances among patients reporting recent alcohol use; and (ii) the number and proportion of ED attendances during high-alcohol hours (Friday and Saturday nights, 20.00-06.00 hours) assigned an injury diagnosis. Process measures will assess logistical and feasibility concerns, and clinical impacts of implementing this systems-change model in an Australian context. An economic cost-benefit analysis will evaluate the economic impact, or return on investment., (© 2019 Australasian College for Emergency Medicine.)

Introduction and Aims: Associations between substance use and aggression may be amplified by simultaneous alcohol and illicit drug use. This study aims to compare differences in involvement in past aggression between people who use different substances while accounting for broader risk propensity., Design and Methods: Self-reported data on past three-month involvement in verbal and physical aggression (victim or perpetrator) were drawn from interviews conducted in night-time entertainment districts in seven Australian cities (n = 5078). Using inverse probability of treatment weighting techniques, participants who reported alcohol versus alcohol and illicit drug use on the night of interview (including ecstasy, cannabis and other illicit stimulant subgroups) were weighted on the basis of drug use risk covariates (e.g. alcohol consumed, gender) to determine differences in involvement in aggression involvement., Results: After weighting for covariates, individuals who reported consuming any illicit drug + alcohol and ecstasy + alcohol combinations were more likely to be involved in physical (33% and 105%, respectively) and verbal (36% and 116%, respectively) aggression in the previous 3-months when compared to those who consumed alcohol only. Cannabis + alcohol and other illicit stimulant + alcohol combinations were no more likely to be involved in either forms of aggression., Discussion and Conclusions: The likelihood of having been involved in past aggressive incidents was higher among those who reported any illicit drug + alcohol and ecstasy + alcohol combinations than those who reported alcohol exclusively, after accounting for covariates. These findings highlight individuals that may benefit most from the development of tailored health promotion/preventative safety interventions in night-time settings., (© 2019 Australasian Professional Society on Alcohol and other Drugs.)

Objective: Transporting people out of nightlife districts is often cited as a major issue associated with alcohol-related harm. The Victorian Government introduced 24-hour public transport (24hr PT) in Melbourne, Australia, on Friday and Saturday nights in January 2016. After the 1-year trial period, funding was extended for a further 4 years, at a cost of more than AU$300 million to date. The current study aimed to determine whether 24hr PT reduced harms associated with the nightlife of Melbourne and whether there has been an increased number of people using the transport and visiting Melbourne city on Friday and Saturday nights., Method: Police assault data, ambulance attendance data, crash data, public transport use data, and pedestrian counting data were analyzed to determine the impact of 24hr PT on harms in the nightlife of Melbourne, as well as changes in the number of people using public transport and attending the city., Results: There was no change from 2015 to 2016 in the number of police-recorded assaults, ambulance attendances, or crashes for the entirety of the night. There were significantly more people out in the city later in the evening, and more people using trains and trams during the 24hr PT time (i.e., 1 A.M.-5 A.M.)., Conclusions: The initiative did not decrease harm in Melbourne nightlife, in contrast to industry, government, and expert predictions. With expenditures of more than AU$300 million, the costs and benefits of this initiative require further consideration and research, especially when it is proposed in opposition to evidence-based solutions, such as closing venues earlier., Competing Interests: Peter Miller receives funding from Australian Research Council and Australian National Health and Medical Research Council; grants from NSW Government, National Drug Law Enforcement Research Fund, Foundation for Alcohol Research and Education, Cancer Council Victoria, Queensland government, and Australian Drug Foundation; and travel and related costs from Australasian Drug Strategy Conference. He has acted as a paid expert witness on behalf of a licensed venue and a security firm.

Background: This paper evaluates the impact of the AU$83 million introduction of 24-h public transport (PT) in Melbourne, Australia on Friday and Saturday nights on a sample of nightlife venues and venue patrons. This sample was selected because a primary reason for the introduction of 24 h PT was to provide a safe means of travel home for nightlife attendees., Methods: Covert venue observations (pre-post) and a convenience sample of nightlife patron interviews (post-only) were conducted to measure the impact of 24-h PT on venues and venue patrons. Specifically, the impact of 24-h PT on the proportion of people observed within venues (as rated on a 0-100% scale of venue capacity), patrons in venues showing any sign of intoxication, those who were observed to be too intoxicated to remain in the venue, patron drinking or drug taking behavior, train use, and the time and money spent in the night time economy were assessed., Results: After 24-h PT was introduced there were no significant differences overall in the proportion of people observed within venues, or significant associations with the proportion of patrons showing any sign of intoxication or proportions who were observed to be too intoxicated to remain in the venue. However, when accounting for seasonality (matching-months), observed patron intoxication increased significantly after the introduction of 24-h PT. The majority of nightlife patrons did not report a change in their pre-drinking or drug taking behavior after 24-public transport, but 44% indicated spending more time in the night time economy, 27% reported spending more money, and 56% reported increasing their train use., Conclusion: Patron reports suggest that 24-h public transport has increased the amount of time people spend in nightlife settings without obviously impacting on drinking behavior. However, supplying 24-h public transport has resulted in greater self-reported use of public transport., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Background: This study aims to explore short-term changes following the introduction of alcohol restrictions (most notably 2 am to 3 am last drinks). We examined patterns of nightlife attendance, intoxication, and alcohol use among patrons shortly before and after restrictions were introduced in Fortitude Valley, Brisbane: the largest night-time entertainment precinct of Queensland., Methods: Street-intercept patron interviews were conducted in Fortitude Valley in June (n = 497) and July (n = 562) 2016. A pre-post design was used to assess changes in time spent out drinking/partying prior to the interview, time of arrival in the precinct, pre-drinking, and blood alcohol concentration (BAC)., Results: Regression models indicated that after the policy introduction, the proportion of people arriving at Fortitude Valley before 10:00 pm increased (OR = 1.38; 95% CI = 1.04, 1.82). Participants reported going out, on average, one hour earlier after the intervention (β = - 0.17; 95% CI = 0.11, 0.22). There was a decrease (RRR = 0.58; 95% CI = 0.43, 0.79) in the proportion of participants who had a high level of intoxication (BAC ≥0.10 g/dL) post-intervention. No other significant differences were found., Conclusions: Earlier cessation of alcohol sales and stopping the sale of rapid intoxication drinks after midnight was associated with people arriving in Fortitude Valley earlier. Though legislative loopholes allowed some venues to continue trading to 5 am, the proportion of people in the precinct who were highly intoxicated decreased after the restriction. Further measurement will be required to determine whether the reduction has persisted.

Aim: To measure changes in alcohol-related emergency department (ED) attendances after introduction of the Sale and Supply of Alcohol Act 2012., Methods: Cross-sectional survey of Christchurch ED attendees in three-week sampling periods in 2013 and 2017. Participants had consumed alcohol within four hours, or their drinking had directly contributed to the attendance. The quantity of alcohol consumed and places of purchase and consumption for the index drinking episode were recorded., Results: From 2013 to 2017 there was a non-significant (p=.41) reduction in the proportion of ED attendees eligible for the study, from 253/3400 (7.4%) to 258/3721 (6.9%). Among participants (n=169 in 2013, n=139 in 2017), liquor store purchasing increased from 41.7% in 2013 to 56.1% in 2017 (p<.01) but there was no significant change in quantity consumed in the index episode; last drink location; percentage of participants with an injury-related attendance; or pre-drinking. In both waves, most participants had purchased alcohol from off-licence venues and consumed their last drink at a private location., Conclusion: Alcohol-related ED attendances remained common after the Sale and Supply of Alcohol Act 2012 was introduced, and they mainly occurred in people who sourced alcohol from off-licence outlets and had their last drink at private locations., Competing Interests: Mr Coleman, Ms Ford and Dr Foulds report grants from New Zealand Health Promotion Agency during the conduct of the study.

We analyze how the content of ecosystem service research has evolved since the early 1990s. Conducting a computational bibliometric content analysis we process a corpus of 14,118 peer-reviewed scientific article abstracts on ecosystem services (ES) from Web of Science records. To provide a comprehensive content analysis of ES research literature, we employ a latent Dirichlet allocation algorithm. For three different time periods (1990-2000, 2001-2010, 2011-2016), we derive nine main ES topics arising from content analysis and elaborate on how they are related over time. The results show that natural science-based ES research analyzes oceanic, freshwater, agricultural, forest, and soil ecosystems. Pollination and land cover emerge as traceable standalone topics around 2001. Social science ES literature demonstrates a reflexive and critical lens on the role of ES research and includes critiques of market-oriented perspectives. The area where social and natural science converge most is about land use systems such as agriculture. Overall, we provide evidence of the strong natural science foundation, the highly interdisciplinary nature of ES research, and a shift in social ES research towards integrated assessments and governance approaches. Furthermore, we discuss potential reasons for observable topic developments., Competing Interests: The authors have declared that no competing interests exist.

Objectives: Despite continued health concerns associated with the practice of consuming alcohol mixed with energy drinks (AmED), few Australian studies have examined the popularity of this combination or attempted to characterise AmED consumers. The purpose of this paper is to replicate two previously used survey approaches to consolidate a national picture of AmED consumption in Australia., Methods: The survey approaches used were: an online survey with a convenience sample of New South Wales (NSW), Australia, residents (n = 1931; 63.7% female; median age 23.0 years); and street intercept surveys in regional and metropolitan entertainment precincts in NSW (n = 1265; 58.2% male; median age 21.0 years). Analyses explored the rates and frequency of AmED use across both samples, and the sociodemographic and substance use predictors of AmED consumption in the past 12 months., Results: More than 90% of participants in both samples reported alcohol consumption in the past 12 months, with approximately 40% of current drinkers also reporting AmED use in the past 12 months. Three-quarters of participants interviewed in entertainment precincts reported alcohol consumption in the previous 12 hours, with one in six of these also reporting AmED consumption in the past 12 hours. AmED users across both samples were more likely than alcohol-only consumers to be younger and male, and to report riskier substance use practices., Conclusions: Health promotion activities are warranted to promote awareness of energy drink guidelines, and the potential harms of exceeding these guidelines, among alcohol consumers. In addition, health workers should consider enquiring about AmED use as an indicator of risk related to substance use., Competing Interests: PM received grants from the Australian Research Council, the Foundation for Alcohol Research and Education, the National Drug Law Enforcement Research Fund, VicHealth and Cancer Council Victoria during the conduct of the study. Personal fees were received from Greenland Legal Pty Ltd, outside the submitted work. This related to PM being an expert witness for a licensed venue and security service legal case.

Introduction and Aims: Breathalyser estimate of blood alcohol concentration (BAC) is widely used as an objective intoxication measure, but is not always practical in nightlife contexts. This study uses in situ data collected in nightlife environments to explore how four measures of intoxication are related so as to inform the development of a more practical and reliable method of differentiating intoxication for people working in the night-time economy., Design and Methods: Nightlife patron interviews were conducted in five Australian cities. Participants completed demographic questions and were asked about current session (past 12 h) alcohol use, and four different measures of intoxication were assessed: BAC, participant's self-reported intoxication (0-10), interviewer rating of the participant's intoxication (0-10) and interviewer-rated number of the participants' of physical signs of intoxication., Results: A total of 7028 patrons were surveyed and n = 5273 included in analysis. Mean age was 23.9 years (SD = 6.36); 61.5% were male. There was a significant difference in occurrence of all observable intoxication symptoms across differing levels of BAC (P < 0.001). All visible symptoms became more common as intoxication increased, except for talking very quickly/talkative and giggly symptoms. As BAC levels increase, the extent of the disagreement between self-rated and interviewer-rated intoxication measures widens. Exhibiting four or more visible intoxication symptoms emerged as a reliable method for observers to identify intoxicated patrons., Discussion and Conclusions: As BAC increases, people become worse at estimating their own intoxication, but sober observers remain relatively accurate. Findings provide support for efforts to strengthen and enforce responsible service of alcohol., (© 2017 Australasian Professional Society on Alcohol and other Drugs.)

Introduction and Aims: Incidences of violence are elevated in night-time entertainment districts. Research suggests that safety-related behavioural strategies adopted while drinking can reduce negative alcohol-related outcomes. The current study investigates the use of safety strategies and its association with experiences of violence among patrons from the general population., Design and Methods: Patron interviews (N = 3949) were conducted in and around licenced venues in Newcastle (New South Wales) and Geelong (Victoria) during peak trading hours (Friday and Saturday, 21:00-01:00 h). Participants (mean age = 24.3, SD = 5.8; male 54.4%) were asked to report what measures, if any, they used to keep safe when drinking and whether they had been involved in a violent incident in the last 12 months., Results: After controlling for patron demographics and location, the use of multiple (more than one) safety strategies was significantly associated with reduced odds of involvement in a violent incident (odds ratio = 0.64, 95% confidence interval 0.49-0.85, P = 0.002). Significant gender differences were observed in the number and type of safety strategies reported., Discussion and Conclusions: Increasing the number of safety-related behaviours during drinking occasions is associated with a small but significant reduction in experiencing alcohol-related harms, such as violence.

Objective: We aimed to quantify the degree to which students pre-gamed in New Zealand, using self-report and breathalysers., Methods: A total of 569 New Zealand undergraduate students were interviewed (men = 45.2%; first year = 81.4%) entering three university-run concerts. We asked participants to report how many drinks they had consumed, their self-reported intoxication and the duration of their pre-gaming session. We then recorded participants' Breath Alcohol Concentration (BrAC; µg/L) and the time they arrived at the event., Results: The number of participants who reported consuming alcohol before the event was 504 (88.6%) and the number of standard drinks consumed was high (M=6.9; median=6.0). A total of 237 (41.7%) participants could not have their BrAC recorded due to having consumed alcohol ≤10 minutes before the interview. The remaining 332 participants (57.3%) recorded a mean BrAC of 288.8µg/L (median=280.0 µg/L). Gender, off-campus accommodation, length of pre-gaming drinking session, and time of arrival at the event were all associated with increased pre-gaming. Conclusion and implications for public health: Pre-gaming was the norm for students. Universities must take pre-gaming into account; policy implications include earlier start times of events and limiting students' access to alcohol prior to events., (© 2017 The Authors.)

Objective: We measured changes in the average level of intoxication over time in the nighttime economy and identified the factors associated with intoxication, including pre-drinking., Method: A random intercept sample of 320 pedestrians (105 women; 215 men) was interviewed and received breath alcohol analysis in the nighttime economy of Hamilton, New Zealand. Data were collected over a five-night period, between 7 P.M. and 2:30 A.M. Data were analyzed by plotting the moving average breath alcohol concentration (BrAC) over time and using linear regression models to identify the factors associated with BrAC., Results: Mean BrAC was 241.5 mcg/L for the full sample; 179.7 for women and 271.7 for men, which is a statistically significant difference. Mean BrAC was also significantly higher among those who engaged in pre-drinking than those who did not. In the regression models, time of night and pre-drinking were significantly associated with higher BrAC. The effect of pre-drinking on BrAC was larger for women than for men., Conclusions: The average level of intoxication increases throughout the night. However, this masks a potentially important gender difference, in that women's intoxication levels stop increasing after midnight, whereas men's increase continuously through the night. Similarly, intoxication of pre-drinkers stops increasing from 11 P.M., although remaining higher than non-pre-drinkers throughout the night. Analysis of BrAC provides a more nuanced understanding of intoxication levels in the nighttime economy.

Introduction and Aims: The current study aimed to examine the association between patron demographics and substance use, and experiences of verbal and physical aggressive incidents within the last 3 months among patrons of night-time entertainment precincts (NEP) in Australia., Design and Methods: Patron interviews (n = 4216) were conducted around licensed venues in the NEPs of five Australian cities. Seven correlates of verbal and physical aggressive incidents were examined: gender, age, occupation, blood alcohol concentration, pre-drinking, energy drink use and illicit drug use in the current session., Results: A total of 7.5% and 8.2% of respondents reported involvement in a verbally and physically aggressive incident in the past 3 months, respectively. Multivariate logistic regression models indicated men and people <25 years old were significantly more likely to report both verbal and physical aggressive incidents. A significant occupation effect showed lower levels of both verbal and physical aggression in managers/professionals compared with non-office workers. The likelihood of being involved in a verbally aggressive incident significantly increased with energy drink consumption, while the likelihood of being involved in a physically aggressive incident significantly increased with blood alcohol concentration, energy drink consumption and illicit drug use., Discussion and Conclusions: This study highlights the different correlates of verbal and physical aggression within NEPs, suggesting they should be viewed as distinct types of violence, rather than points on a continuum. Major modifiable correlates with verbal and physical aggression included intoxication, energy drink consumption, and illicit drug use, suggesting the need for further interventions and policy development to address these key issues.

Objective: Determine the relationship of subjective intoxication to blood alcohol concentration (BAC) and examine whether patron and event-level characteristics modify the relationship of BAC to subjective intoxication., Methods: An in-situ systematic random sample of alcohol consumers attending night-time entertainment districts between 10pm and 3am on Friday and Saturday nights in five Australian cities completed a brief interview (n=4628). Participants reported age, sex, and pre-drinking, energy drink, tobacco, illicit stimulant and other illicit drug use that night, and their subjective intoxication and BAC were assessed., Results: Male and female drinkers displayed equally low sensitivity to the impact of alcohol consumption when self-assessing their intoxication (BAC only explained 19% of variance). The marginal effect of BAC was not constant. At low BAC, participants were somewhat sensitive to increases in alcohol consumption, but at higher BAC levels that modest sensitivity dissipated (actual BAC had less impact on self-assessed intoxication). The slope ultimately leveled out to be non-responsive to additional alcohol intake. Staying out late, pre-drinking, and being young introduced biases resulting in higher self-assessed intoxication regardless of actual BAC. Further, both energy drinks and stimulant use modified the association between BAC and perceived intoxication, resulting in more compressed changes in self-assessment as BAC varies up or down, indicating less ability to perceive differences in BAC level., Conclusions: The ability of intoxicated patrons to detect further intoxication is impaired. Co-consumption of energy drinks and/or stimulant drugs is associated with impaired intoxication judgment, creating an additional challenge for the responsible service and consumption of alcohol., (Copyright © 2017 Elsevier Ltd.

Research on nightlife and drinking faces many unique challenges, and validity in research is an important concern. A recent publication by Devilly et al. entitled "SmartStart: Results of a large point of entry study into preloading alcohol and associated behaviours" contains definitions and assumptions about prior work that require more careful consideration. Important issues include: using a definition of pre-drinking which is the same as previous work so that valid comparison can be made, reporting of blood alcohol concentration (BAC) levels that comply with other work, accurate reporting of response rates, and careful consideration of sampling approaches to maximise ethical integrity. Ensuring consistency of definition and accurate representation of previous literature regarding BAC, pre-drinking and energy drink use, is important for supplying the broader community with reliable information on which policy decisions can be made., (Copyright © 2017 Elsevier B.V.

Background: Alcohol-related harm is a substantial burden on the community in Australia and internationally, particularly harm related to risky drinking practices of young people in the night-time economy. This protocol paper describes a study that will report on the changes in a wide range of health and justice outcome measures associated with major policy changes in the state of Queensland, Australia. A key element includes trading hours restrictions for licensed premises to 2 am for the state and 3 am in Safe Night Precincts (SNPs). Other measures introduced include drinks restrictions after midnight, increased patron banning measures for repeat offenders, mandatory ID scanning of patrons in late-night venues, and education campaigns., Methods: The primary aim of the study is to evaluate change in the levels of harm due to these policy changes using administrative data (e.g., police, hospital, ambulance, and court data). Other study elements will investigate the impact of the Policy by measuring foot traffic volume in SNPs, using ID scanner data to quantify the volume of people entering venues and measure the effectiveness of banning notices, using patron interviews to quantify the levels of pre-drinking, intoxication and illicit drug use within night-time economy districts, and to explore the impacts of the Policy on business and live music, and costs to the community., Discussion: The information gathered through this project aims to evaluate the effectiveness of the Policy and to draw on these findings to inform future prevention and enforcement approaches by policy makers, police, and venue staff.

Objective: Scientific research is essential to the development of effective addiction treatment and drug policy. Actions that compromise the integrity of addiction science need to be understood. The aim of this study is to investigate funder (e.g. industry, government or charity) interference in addiction science internationally., Method: Corresponding authors of all 941 papers published in an international specialist journal July 2004 to June 2009 were invited to complete a web questionnaire. A sensitivity analysis with extreme assumptions about non-respondents was undertaken., Results: The questionnaire was completed by 322 authors (response fraction 34%), 36% (n=117) of whom had encountered at least one episode (median=3, Interquartile range=4) of funder interference in their research: 56% in Australasia, 33% in Europe, and 30% in North America. Censorship of research outputs was the most common form of interference. The wording or writing of reports and articles, as well as where, when and how findings were released were the areas in which influence was most often reported., Conclusions: Funder interference in addiction science appears to be common internationally. Strategies to increase transparency in the addiction science literature, including mandatory author declarations concerning the role of the funder, are necessary., (Copyright © 2017.

Background: Negative physiological stimulation and sedation side effects are experienced by a significant proportion of consumers who consume alcohol mixed with energy drinks (AmED). Few studies have compared the frequency of side effects between sessions of AmED and sessions of alcohol only within-subject, and none have explored a dose relationship., Objectives: Explore the occurrence of self-reported physiological stimulant and sedative side effects between sessions of AmED and alcohol only, and at varying ED dosage levels within AmED sessions., Methods: A convenience sample of 2953 residents of New South Wales, Australia completed an online survey. N=731 AmED users reported daily caffeine intake, typical alcohol and AmED consumption, and past 12-month experience of physiological stimulation and sedation side effects during AmED and alcohol only sessions. Within-subject analyses compared occurrence of side effects between session types. Hierarchical binary logistic regression analyses explored the association of ED dose during AmED sessions with the experience of physiological side effects., Results: There were greater odds of most stimulant side effects, and lower odds of sedation side effects, during AmED sessions compared to alcohol only sessions. Compared to one ED, consumption of three or more EDs was significantly associated with the majority of both stimulant and alcohol intoxication side effects after controlling for demographics and consumption covariates., Conclusions: AmED is associated with perceived changes in physiological stimulant and sedation side effects of alcohol. Experience of side effects is positively associated with ED dosage. Future research should account for varying ED dosage, and reflect real world consumption levels., (Copyright © 2017 Elsevier Ltd.

Background: While alcohol-related harm is reportedly greater on weekend evenings, research investigating trends in the intoxication levels of patrons and factors that increase risk of harm over the night is lacking., Objectives: The aim was to observe trends over the course of the night for patron demographics, venue characteristics and patron intoxication., Methods: Observations of licensed venues and patrons in night-time entertainment districts of five Australian cities were conducted. In total, 798 observations occurred between 9 pm and 2 am on Friday and Saturday nights across 61 unique bars, nightclubs, and pubs. Patron characteristics such as gender and percentage of patrons under 25 years of age were estimated. Measures of venue characteristics included number of patrons, percentage venue capacity, ease of patron movement, bar crowding, and time to service. Measures of intoxication included the percentage of patrons showing any signs of alcohol intoxication, percentage of patrons too intoxicated to remain in the venue, overall level of intoxication, and percentage of patrons showing signs of drug use., Results: Patron capacity increased across the night, peaking at 11 pm in bars, and 1 am in nightclubs. Patron intoxication measures increased for all venue types across the night. Patrons showed more signs of drug use in nightclubs than other venue types., Conclusions: Increasing intoxication and decreasing patron numbers later in the night provides support for restricted trading hours and improved responsible service of alcohol policies. Specific venue types should be targeted to reduce drug use in the night-time economy.

Introduction and Aims: The relationship between alcohol intoxication and harm is well known, and many community-based interventions have been introduced in an attempt to reduce the rates of alcohol-related harm. The current paper uses two metropolitan and two regional Australian cities as sites to investigate the impact of community-based interventions on the reduction of alcohol-related harms., Design and Methods: Data for injury-related emergency department (ED) presentations and police attended assaults during high-alcohol hours (i.e. 20:00-06:00 h, Friday and Saturday nights) were obtained for each site from 2000 to 2015 for ED presentations and from 2000 to 2016 for police assaults. Autoregressive integrated moving average time series analyses were conducted to determine the impact of the community-based interventions introduced at each site for reducing these rates of ED injury presentations and police attended assaults., Results: None of the community-level interventions that were introduced across the four sites resulted in a reduction in ED presentation rates or assault rates., Discussion and Conclusions: The majority of interventions introduced across the four sites were proposed and implemented by local liquor accords. Given none of the interventions demonstrated a reduction in ED injury presentation rates or police attended assault rates, it is argued that local liquor accords may not be best placed to propose alcohol-related harm reduction measures, and instead, there should be a focus on the implementation of evidence-based regulatory strategies, such as restricted trading hours.

This study examined the relationship between patron demographics, substance use, and experience of recent alcohol-related accidents and injuries that were not due to interpersonal violence in night-time entertainment districts. Cross-sectional interviews ( n = 4016) were conducted around licensed venues in entertainment districts of five Australian cities. Demographic factors associated with non-violent alcohol-related injuries were examined, including gender, age, and occupation. The association between substance use on the night of interview; blood alcohol concentration (BAC), pre-drinking, energy drink consumption, and illicit drug use; and experience of injury was also explored. Thirteen percent of participants reported an alcohol-related injury within the past three months. Respondents aged younger than 25 years were significantly more likely to report an alcohol-related injury. Further, a significant occupation effect was found indicating the rate of alcohol-related injury was lower in managers/professionals compared to non-office workers. The likelihood of prior alcohol-related injury significantly increased with BAC, and self-reported pre-drinking, energy drink, or illicit drug consumption on the night of interview. These findings provide an indication of the demographic and substance use-related associations with alcohol-related injuries and, therefore, potential avenues of population-level policy intervention. Policy responses to alcohol-related harm must also account for an assessment and costing of non-violent injuries., Competing Interests: Peter Miller receives funding from Australian Research Council and Australian National Health and Medical Research Council, grants from NSW Government, National Drug Law Enforcement Research Fund, Foundation for Alcohol Research and Education, Cancer Council Victoria, Queensland government and Australian Drug Foundation, travel and related costs from Australasian Drug Strategy Conference.

Introduction and Aims: Industry groups with vested interests in policy regularly work to protect their profits via the endorsement of ineffective voluntary regulation and interventions, extensive lobbying activity and minimising the health impact of consumption behaviours. This study aims to examine all alcohol industry submissions to the Australian House of Representatives Standing Committee on Social Policy and Legal Affairs into Fetal Alcohol Spectrum Disorders (FASD), to assist in understanding how those with vested interests contribute to policy development. The analysis aims to document the strategies and arguments used by alcohol industry bodies in their submissions and to compare these with known strategies of vested-interest groups., Design and Methods: All 92 submissions to the Inquiry were screened to include only those submitted by alcohol industry bodies (five submissions). Content domains were derived based on the major themes emerging from the industry submissions and on common vested-interest behaviours identified in previous literature., Results: The following content categories were identified: Concerns about FASD; Current industry activities and FASD prevention; Value of mandatory warning labels; and Credibility of independent public health researchers and organisations., Discussion and Conclusions: Alcohol industry submissions sought to undermine community concern, debate the evidence, promote ineffective measure which are no threat to the profit margins and attack independent health professionals and researchers. In doing so, their behaviour is entirely consistent with their responses to other issues, such as violence and chronic health, and copies the tactics employed by the tobacco industry.

Background: The aim of the current study was to assess correlates of intoxication in licensed venues in Australia., Methods: Covert observations of licensed venues and venue patron in night-time entertainment districts of five Australian cities were conducted. In total, 828 unique cross-sectional observations were completed across 62 bars, nightclubs, and large mainstream pubs. Venues were selected from the main entertainment district of smaller cities and the busiest entertainment districts of larger cities. Outcomes were the estimated percentage of patrons showing any signs of alcohol intoxication and the overall level of intoxication ('high' versus 'none to medium'). Seven predictors of patron intoxication were examined: hour of observation; estimated percentage of male patrons; estimated percentage of patrons <25 years old; venue crowding; presence of observable alcohol promotions; type of alcoholic beverage consumed by the majority of patrons; and, venue type., Results: Time of night (coefficient=11.71, p<.001; OR=9.61, p<.001), percentage of patrons aged <25 (coefficient=0.14, p<.001; OR=1.01, p=.031), and venue crowding (coefficient=4.40, p<.001; OR=1.39, p=.009) had significant positive associations with both signs of intoxication and high levels of intoxication. Nightclubs had a lower percentage of signs of intoxication compared to pubs (coefficient=-10.73, p=.021). Increased percentage of male patrons was associated with increased odds of high-level intoxication (OR=1.05, p=.020)., Conclusion: Time of night and proportion of younger patrons had a strong association with patron intoxication adding further support for the strong body of evidence that ceasing service of alcohol earlier in the evening will reduce intoxication levels., (Copyright © 2016 Elsevier B.V.

Background: Drink driving is a significant public health concern, and contributes to many road fatalities worldwide. The current study is the first to examine the prevalence and correlates of drink driving behavior in a sample of night-time entertainment precinct attendees in Australia., Methods: Interviews were conducted with 4214 night-time entertainment precinct attendees in two metropolitan and three regional cities in Australia. Seven correlates of self-reported drink driving were examined: gender, age, occupation, blood alcohol concentration (BAC), alcohol consumed prior to attending a licensed venue, energy drink consumption, and other drug consumption., Results: Fourteen percent of night-time entertainment precinct attendees reported drink driving in the past three months. Bivariate logistic regression models indicated that males were significantly more likely than females to report drink driving in the past three months. Blue-collar workers and sales/clerical/administrative workers were significantly more likely to report drink driving behavior in the past three months than white-collar workers. The likelihood of reporting drink driving during the three months prior to interview significantly increased as BAC on the current night out increased, and when patrons reported engaging in pre-drinking or other drug use. The multivariate model presented a similar pattern of results, however BAC and pre-drinking on the night of the interview were no longer independent significant predictors., Conclusions: Males, blue collar/sales/clerical/administrative workers, and illicit drug consumers were more likely to report engaging in drink driving behavior than their counterparts. Interventions should focus on addressing the considerable proportion night-time entertainment precinct attendees who report engaging in drink driving behavior., (Copyright © 2016 Elsevier Ltd.

Background: Environmental factors inside licensed venues have been found to influence the intoxication levels and consumption practices of patrons. The consumption of alcohol mixed with energy drinks (AmED) occurs primarily at or prior to attending licensed venues, however there is a lack of in situ research investigating AmED use in these contexts. Given that AmED use has been linked with increased alcohol consumption, intoxication, illicit substance use, and risk taking behaviours, this paper explores the environmental correlates and levels of intoxication associated with AmED use in licensed venues., Methods: Structured observations were undertaken in five Australian cities on Friday and Saturday nights. Covert teams spent 4-5h in venues and recorded hourly observations on patron, venue, and staff characteristics, alcohol, illicit drug and AmED consumption patterns and intoxication levels., Results: 898 hourly observations were recorded across 68 venues. All but one venue served energy drinks, and patron AmED use was observed during 34.9% of hourly records. AmED use was more prevalent after 12am and in nightclub venues compared to bars and pubs, and was positively associated with high intoxication levels, illicit drug use, and younger crowds. After controlling for environmental factors (i.e. venue crowding, service practices, venue characteristics, patron demographics and behaviour) AmED use did not predict high intoxication at a venue level in multivariable models., Conclusion: AmED consumption is ubiquitous in the licensed venues of Australian night-time entertainment districts, particularly busy nightclub venues where intoxication and risky consumption are heightened. However, AmED use was not associated with high patron intoxication when environmental factors were considered., (Copyright © 2016 Elsevier B.V. All rights reserved.)

Introduction and Aims: Understanding how types of alcohol consumers differ is important for public policy targeted at reducing adverse events. The aims of the present study were to identify typologies of alcohol consumers in Australian nighttime entertainment districts based on risk factors for harm and to examine variation between the identified groups in drinking setting and harms., Design and Methods: Street-intercept surveys were conducted with 5556 alcohol consumers in and around licensed venues in five Australian cities between November 2011 and June 2012. Latent class analysis identified groups based on age and sex, and blood alcohol concentration, pre-drinking, energy drink use and illicit drug use during that night., Results: Four classes were identified: general patron group (33%), young pre-drinker group (27%), intoxicated male pre-drinker group (31%) and intoxicated illicit drug male group (9%). The proportion of the general patron group interviewed decreased over the night, while the other groups increased (particularly in regional cities). As compared with the general patron group, the remaining three groups reported increased odds of being involved in aggression and any alcohol-related injuries in the past 3 months, with highest rates of harm amongst the intoxicated illicit drug male group., Discussion and Conclusions: Alcohol consumers in nighttime entertainment districts are not a homogeneous group. One-third have a low likelihood of risky consumption practices; however, representation of this consumer class diminishes throughout the night. Elevated harms amongst groups characterised by certain risk factors (e.g. pre-drinking and illicit drug use) emphasise the importance of addressing these behaviours in public policy.

Introduction and Aims: Liquor accords were introduced as an intervention to reduce alcohol-related harm in and around licensed venues. There have been very few evaluations of the accords, made all the more difficult given the multitude of measures that are often implemented under their banner. This study provides perspectives on the effectiveness of the liquor accords from key stakeholders who were involved in the strategy., Design and Methods: In-depth interviews were conducted with 97 key stakeholders as part of a larger study, of which 46 spoke about the effectiveness of liquor accords. Responses were analysed using thematic analysis., Results: Stakeholders reported the greatest benefit of liquor accords to be their ability to improve communication. Many stakeholders recognised the need for mandatory attendance and discussed whether the accords are a waste of time of resources. Stakeholders did not generally view liquor accords as effective means of reducing alcohol-related harm., Discussion: There was a lack of positive feedback about liquor accords provided by stakeholders, indicating a clear need to better understand the role of liquor accords, and what they aim to achieve. Responsive regulation theory suggests that the dual roles of communication and intervention are confused, leading to some of the inherent problems with accords., Conclusions: The role and aims of liquor accords need to be clearly defined. The findings suggest that separating the communication and regulatory functions from accords will lead to a clearer role for accords, and interventions and regulation might be better placed in the hands of regulators and enforcement.

Introduction and Aims: The study investigates the prevalence of pre-drinking culture in the night-time economy (NTE) and its impact upon intoxication and alcohol-related harm and violence experienced by patrons., Design and Methods: Cross-sectional surveys were conducted in and around licensed venues in Newcastle (NSW) and Geelong (Victoria) during peak trading hours (typically 9pm-1am). Participants completed a five minute structured interview which targeted: demographics, past and planned movements on the survey night, safety/experience of harm, and patron intoxication. 3949 people agreed to be interviewed, a response rate of 90.7%. Around half (54.9%) of interviewees were male and mean age was 24.4 years (SD = 5.8)., Results: 66.8% of participants reported pre-drinking prior to attending licensed venues. On a 1-10 scale measuring self-rated intoxication, pre-drinkers scored significantly higher compared to non pre-drinkers (P < 0.001). Compared to non-pre-drinkers, patrons who had consumed 6-10 standard pre-drinks were 1.5 times more likely to be involved in a violent incident in the past 12 months (OR = 1.50, 95%CI 1.03-2.19, P = 0.037) increasing to 1.8 times more likely for patrons who had 11-15 drinks (OR = 1.80, 95%CI 1.04-3.11 P = .036). Pre-drinking was also associated with both self-rated and observer-rated intoxication, as well as increased probability of illicit drug use. Amongst pre-drinkers, price was the most commonly reported motive for pre-drinking (51.8%)., Discussion and Conclusions: 'Pre-drinking' was normal behaviour in the current sample and contributes significantly to the burden of harm and intoxication in the NTE. Price disparity between packaged vs. venue liquor is a key motivator for pre-drinking., (© 2015 Australasian Professional Society on Alcohol and other Drugs.)

Background: Despite concern regarding harms of energy drink (ED) consumption, no research has been conducted to determine awareness and compliance with ED intake guidelines displayed on product packaging in Australia (a novel approach internationally)., Methods: A convenience sample of 1922 people completed an online survey. Participants reported their knowledge of maximum recommended daily ED intake according to Australian guidelines., Results: Guideline awareness was reported by 38, 23 and 19% of past year consumers, lifetime, and non-consumers, respectively. Amongst past year consumers, 'accurate estimators' reported greater ED intake and were more likely to exceed intake guidelines and consume alcohol mixed with ED (AmED). After controlling for demographics and frequency of use, guideline awareness predicted increased likelihood of exceeding guidelines in ED sessions, but was not associated with exceeding ED guidelines in AmED sessions., Conclusions: Australia is considered to have the most stringent regulatory approach to EDs internationally. However, advisory statements are not associated with greater awareness and compliance with intake guidelines. Failure to comply with standards for efficacious product labelling, and absence of broader education regarding guidelines, needs to be addressed.

Aims: This study aimed to (1) estimate the prevalence of illicit drug use in night-time entertainment districts across five major cities in Australia; and (2) validate self-reported drug use using biochemical marker oral swabs., Design: Street intercept surveys and oral drug swabs conducted over a 7-month period during 2011-12., Setting: The night-time entertainment districts of three metropolitan cities (Sydney, Melbourne and Perth) and two regional cities (Wollongong and Geelong) in Australia, between the hours of 10 p.m. and 5 a.m., Participants: A total of 7581 individuals agreed to participate in the survey (93% response rate). More than half (62%) the sample was male, with a median age of 22 years (range 18-73)., Measurements: Patrons were approached in thoroughfares and while entering and leaving licensed venues. Data collected included demographics and current session alcohol and other substance use. Drug swabs (n = 401) were performed with a subsample of participants., Findings: Approximately 9% [95% confidence interval (CI) = 7-12%] of participants self-reported consumption of illicit or non-prescribed pharmaceutical drugs prior to interview; of those, 81% identified psychostimulants as the drug used. One in five drug swabs returned a positive result, with psychostimulants the most commonly detected drugs (15%; 95% CI = 12-19%). Kappa statistics indicate agreement between self-report of any illicit drug and a positive drug swab is in the slight range [κ = 0.12 (95% CI = 0.05-0.20) P = 0.000]., Conclusions: Self-report findings suggest drug use in Australian nightlife is common, although still very much a minority past-time. Drug swabs indicate a higher prevalence of use (20%) than self-report (9%), which suggests that self-reported drug use may not be reliable in this context., (© 2015 Society for the Study of Addiction.)

Background: There has been a significant growth in the energy drink (ED) market in Australia and around the world; however, most research investigating the popularity of ED and alcohol and energy drink (AED) use has focused on specific subpopulations such as university students. The aim of this study was to estimate the prevalence, consumption patterns, and sociodemographic correlates of ED and combined AED use among a representative Australian population sample., Methods: A computer-assisted telephone interview survey (n = 2,000) was undertaken in March-April 2013 of persons aged 18 years and over. Half of the interviews were obtained through randomly generated landline telephone numbers and half through mobile phones. Approximately half of the sample was female (55.5%; n = 1,110) and the mean age of participants was 45.9 (range 18 to 95, SD 20.0)., Results: Less than 1 in 6 Australians reported ED use (13.4%, n = 268) and 4.6% (n = 91) reported AED use in the past 3 months. Majority of ED and AED users consumed these beverages monthly or less. ED and AED users are more likely to be aged 18 to 24 years, live in a metropolitan area, and be moderate risk or problem gamblers. AED consumers are more likely to report moderate levels of psychological distress., Conclusions: Our findings in relation to problem gambling and psychological distress are novel and require further targeted investigation. Health promotion strategies directed toward reducing ED and AED use should focus on young people living in metropolitan areas and potentially be disseminated through locations where gambling takes place., (Copyright © 2015 by the Research Society on Alcoholism.)

Background: Previous research on alcohol mixed with energy drinks (AmED) has shown that use is typically driven by hedonistic, social, functional, and intoxication-related motives, with differential associations with alcohol-related harm across these constructs. There has been no research looking at whether there are subgroups of consumers based on patterns of motivations. Consequently, the aims were to determine the typology of motivations for AmED use among a community sample and to identify correlates of subgroup membership. In addition, we aimed to determine whether this structure of motivations applied to a university student sample., Methods: Data were used from an Australian community sample (n = 731) and an Australian university student sample (n = 594) who were identified as AmED consumers when completing an online survey about their alcohol and ED use. Participants reported their level of agreement with 14 motivations for AmED use; latent classes of AmED consumers were identified based on patterns of motivation endorsement using latent class analysis., Results: A 4-class model was selected using data from the community sample: (i) taste consumers (31%): endorsed pleasurable taste; (ii) energy-seeking consumers (24%): endorsed functional and taste motives; (iii) hedonistic consumers (33%): endorse pleasure and sensation-seeking motives, as well as functional and taste motives; and (iv) intoxication-related consumers (12%): endorsed motives related to feeling in control of intoxication, as well as hedonistic, functional, and taste motives. The consumer subgroups typically did not differ on demographics, other drug use, alcohol and ED use, and AmED risk taking. The patterns of motivations for the 4-class model were similar for the university student sample., Conclusions: This study indicated the existence of 4 subgroups of AmED consumers based on their patterns of motivations for AmED use consistently structured across the community and university student sample. These findings lend support to the growing conceptualization of AmED consumers as a heterogeneous group in regard to motivations for use, with a hierarchical and cumulative class order in regard to the number of types of motivation for AmED use. Prospective research may endeavor to link session-specific motives and outcomes, as it is apparent that primary consumption motives may be fluid between sessions., (Copyright © 2015 by the Research Society on Alcoholism.)

Objective: The present study summarises the methodology and findings of a pilot project designed to measure the sources and locations of alcohol-related harm by implementing anonymised 'last drinks' questions in the ED of a rural community., Methods: 'Last drinks' questions were added to computerised triage systems at South West Healthcare ED in rural Warrnambool, Victoria, from 1 November 2013 to 3 July 2014. For all injury presentations aged 15 years or older, attendees were asked whether alcohol was consumed in the 12 h prior to injury, how many standard drinks were consumed, where they purchased most of the alcohol and where they consumed the last alcoholic drink., Results: From 3692 injury attendances, 10.8% (n = 399) reported consuming alcohol in the 12 h prior to injury. 'Last drinks' data collection was 100% complete for participants who reported alcohol use prior to injury. Approximately two-thirds (60.2%) of all alcohol-related presentations had purchased their alcohol at packaged liquor outlets. During high-alcohol hours, alcohol-related injuries accounted for 36.1% (n = 101) of all ED injury presentations, and in total 41.7% of alcohol-related attendances during these hours reported consuming last drinks at identifiable hotels, bars, nightclubs or restaurants, or identifiable public areas/events., Conclusions: This pilot demonstrates the feasibility and reliability of implementing sustainable 'last drinks' data collection methods in the ED, and the ability to effectively map the source of alcohol-related ED attendances in a rural community., (© 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.)
