The impact of exposure to wagering advertisements and inducements on intended and actual betting expenditure: An ecological momentary assessment study.

BACKGROUND AND AIMS: Research suggests that a large proportion of regular sports and race bettors experience harm related to their gambling. In Australia, people who bet regularly are targeted by a proliferation of different forms of inducements and advertising - many of which are believed to encourage excessive betting and erroneous perceptions of risk. However, scant research has examined the impact of marketing messaging to this group, which is also limited to cross-sectional or qualitative designs. We aimed to determine whether exposure to wagering advertisements and inducements influenced intended betting expenditure, actual betting expenditure, and spending more than intended. METHODS: We report on an ecological momentary assessment study, measuring regular exposure to 20 different forms of marketing, as well as wagering spend from 318 race bettors and 279 sports bettors. Up to 15 assessments per participant were conducted over 3 weeks (mean = 11.46, median = 14), yielding 6,843 observations for analysis. RESULTS: Exposure to advertising and inducements was reliably linked to a greater likelihood of betting, higher intended and actual betting expenditure, and spending more than intended. "Push" messaging and inducements that convey the impression of reduced risk (stake-back inducements and multibet offers) were particularly influential, as well as brands promoted during events and advertisements on betting websites/apps. DISCUSSION AND CONCLUSIONS: Given that a large proportion of regular sports and race bettors experience problems, restrictions on these forms of marketing are advisable. These findings suggest that this is particularly important for marketing that is "pushed" to gamblers or that suggests reduced risk.

Where's the Bonus in Bonus Bets? Assessing Sports Bettors' Comprehension of their True Cost.

Wagering inducements with bonus bets are prominently marketed and often have play-through conditions requiring further expenditure. However, these conditions are not usually presented in the inducement advertisement and may be difficult to locate. The play-through conditions themselves are complex and may lead bettors to miscalculate the inducement's true cost. Therefore, in relation to inducements with bonus bets, this study aimed to assess: (1) whether their perceived attractiveness varies with the amount and type of information provided about their play-through conditions; (2) bettors' comprehension of their true cost; and (3) whether bettors' comprehension of their true cost varies with problem gambling severity. A sample of 299 Australian sports bettors completed an online survey and rated the attractiveness of three variations of an inducement. Promo1 simply noted that "terms and conditions apply"; promo2 included the terms and conditions immediately below the offer; and promo3 revealed the true cost of the offer. Respondents were asked to calculate the true cost before this was revealed. The study found that detailing key terms and conditions for an offer directly below the advertisement impacts negatively on its perceived attractiveness. Moreover, nearly three in five bettors underestimated the additional amount they would need to bet to access any winnings from the bonus bet. No significant differences were found amongst gambler risk groups. The results imply that current approaches to marketing these inducements are likely to lead consumers to overestimate their attractiveness and underestimate their cost. To enhance responsible gambling practice, these promotional offers should be presented in ways that enable informed decision-making.

Investigating Differences Between Drugs Used in the Australian Night-Time Economy: Demographics, Substance Use, and Harm.

BACKGROUND: Understanding the characteristics of drug users in the night-time economy (NTE), and whether particular drugs are associated with risky practices and experience of harm, is necessary to inform targeted policy responses in this context. OBJECTIVES: To investigate the correlates of drugs used in the Australian NTE relating to demographics, alcohol use, and experience of harm. METHODS: Patrons were interviewed in the NTE of five Australian cities in 2012-2013 (n = 7,028; 61.9% male, median age 22 years). A custom designed survey gathered demographic data, alcohol, and substance use on the current night, and experience of harm in/around licensed venues in the past 3 months. Multivariate logistic regression analyses examined the correlates of drug use. RESULTS: Ecstasy was most commonly reported (4.0%), followed by cannabis (2.9%), methamphetamine (2.6%), and cocaine (1.6%). Ecstasy users were more likely to be younger and report energy drink consumption. Cannabis users were more likely to be male, and to have been involved in intoxication-related accidents/injuries and sexual aggression in/around licensed venues in the past 3 months. Methamphetamine users were more likely to have been interviewed later, and to have engaged in pre-drinking. Cocaine users were more likely to be male, aged 21 years or more, have a blood alcohol concentration of greater than 0.10%, and to have been involved in intoxication-related accidents/injuries in the past three months. Conclusions/Importance: We identified significant differences between types of drug users and the harms they experience, underscoring the need to develop innovative harm reduction policies in the NTE rather than blanket population-based approaches.

'Wide-awake drunkenness'? Investigating the association between alcohol intoxication and stimulant use in the night-time economy.

AIMS: We tested whether patrons of the night-time economy who had co-consumed energy drinks or illicit stimulants with alcohol had higher blood alcohol concentration (BAC) levels than patrons who had consumed only alcohol. DESIGN: Street intercept surveys (n = 4227) were undertaken between 9 p.m. and 5 a.m. over a period of 7 months. SETTING: Interviews were undertaken with patrons walking through entertainment precincts, queuing to enter venues or exiting venues in five Australian cities. PARTICIPANTS: The response rate was 92.1%; more than half the study sample was male (60.2%) and the median age was 23 years (range 18-72). MEASUREMENTS: Data were collected on demographics, length of drinking session, venue types visited, types and quantity of alcohol consumed and other substance use. A BAC reading was recorded and a subsample of participants was tested for other drug use. FINDINGS: Compared with the total sample (0.068%), illicit stimulant consumers (0.080%; P = 0.004) and energy drink consumers (0.074%; P < 0.001) had a significantly higher median BAC reading, and were more likely to engage in pre-drinking (65.6, 82.1 and 77.6%, respectively, P < 0.001) and longer drinking sessions (4, 5 and 4.5 hours, respectively, P < 0.001). However, stimulant use was not associated independently with higher BAC in the final multivariable model (illicit stimulants P = 0.198; energy drinks P = 0.112). Interaction analyses showed that stimulant users had a higher BAC in the initial stages of the drinking session, but not after 4-6 hours. CONCLUSIONS: While stimulant use does not predict BAC in and of itself, stimulants users are more likely to engage in prolonged sessions of heavy alcohol consumption and a range of risk-taking behaviours on a night out, which may explain higher levels of BAC among stimulants users, at least in the initial stages of the drinking session.

The diversion and injection of a buprenorphine-naloxone soluble film formulation.

BACKGROUND: We compared the diversion and injection of a new formulation of buprenorphine, a buprenorphine-naloxone film product (BNX film), with buprenorphine-naloxone tablets (BNX tablets), mono-buprenorphine (BPN) and methadone (MET) in Australia. METHODS: Surveys were conducted with people who inject drugs regularly (PWID) (2004-2012) and opioid substitution treatment (OST) clients (2012, N=543). Key outcome measures: the unsanctioned removal of supervised doses, diversion, injection, motivations, drug liking and street price. Levels of injection among PWID were adjusted for background availability of medication using sales data. Doses not taken as directed by OST clients were adjusted by total number of daily doses dispensed. RESULTS: Among out-of-treatment PWID, levels of injection for BNX film were comparable to those for MET and BNX tablet formulations, adjusting for background availability; BPN injecting levels were higher. Among OST clients, recent injecting of one's medication was similar among clients in all OST types; weekly or more frequent injection of prescribed doses was reported by fewer BNX film clients (3%; 95% CI: 1-6) than BPN clients (11%; 95% CI: 3-17), but at levels similar to those observed among MET and BNX tablet clients. The proportion of BNX film doses injected was lower than that for BPN and BNX tablets, and equivalent to that for MET. The majority of BNX film doses injected by OST clients were unsupervised doses, although some injection of supervised doses of BNX film did occur. The median price of all buprenorphine forms on the illicit market was the same. CONCLUSIONS: Non-adherence and diversion of the BNX film formulation was similar to MET and BNX tablet formulations; BPN had higher levels of all indicators of non-adherence and diversion.

SimAmph: an agent-based simulation model for exploring the use of psychostimulants and related harm amongst young Australians.

BACKGROUND: Computer simulations provide a useful tool for bringing together diverse sources of information in order to increase understanding of the complex aetiology of drug use and related harm, and to inform the development of effective policies. In this paper, we describe SimAmph, an agent-based simulation model for exploring how individual perceptions, peer influences and subcultural settings shape the use of psychostimulants and related harm amongst young Australians. METHODS: We present the conceptual architecture underpinning SimAmph, the assumptions we made in building it, the outcomes of sensitivity analysis of key model parameters and the results obtained when we modelled a baseline scenario. RESULTS: SimAmph's core behavioural algorithm is able to produce social patterns of partying and recreational drug use that approximate those found in an Australian national population survey. We also discuss the limitations involved in running closed-system simulations and how the model could be refined to include the social, as well as health, consequences of drug use. CONCLUSION: SimAmph provides a useful tool for integrating diverse data and exploring drug policy scenarios. Its integrated approach goes some way towards overcoming the compartmentalisation that characterises existing data, and its structure, parameters and values can be modified as new data and understandings emerge. In a companion paper (Dray et al., 2011), we use the model outlined here to explore the possible consequences of two policy scenarios.

Are drug detection dogs and mass-media campaigns likely to be effective policy responses to psychostimulant use and related harm? Results from an agent-based simulation model.

BACKGROUND: Agent-based simulation models can be used to explore the impact of policy and practice on drug use and related consequences. In a linked paper (Perez et al., 2011), we described SimAmph, an agent-based simulation model for exploring the use of psychostimulants and related harm amongst young Australians. METHODS: In this paper, we use the model to simulate the impact of two policy scenarios on engagement in drug use and experience of drug-related harm: (i) the use of passive-alert detection (PAD) dogs by police at public venues and (ii) the introduction of a mass-media drug prevention campaign. RESULTS: The findings of the first simulation suggest that only very high rates of detection by PAD dogs reduce the intensity of drug use, and that this decrease is driven mainly by a four-fold increase in negative health consequences as detection rates rise. In the second simulation, our modelling showed that the mass-media prevention campaign had little effect on the behaviour and experience of heavier drug users. However, it led to reductions in the prevalence of health-related conditions amongst moderate drug users and prevented them from becoming heavier users. CONCLUSION: Agent-based modelling has great potential as a tool for exploring the reciprocal relationships between environments and individuals, and for highlighting how intended changes in one domain of a system may produce unintended consequences in other domains. The exploration of these linkages is important in an environment as complex as the drug policy and intervention arena.

Trends in morphine prescriptions, illicit morphine use and associated harms among regular injecting drug users in Australia.

This paper examines population trends in morphine prescriptions in Australia, and contrasts them with findings from annual surveys with regular injecting drug users (IDU). Data on morphine prescriptions from 1995 to 2003 were obtained from the Drug Monitoring System (DRUMS) run by the Australian Government Department of Health and Ageing. Data collected from regular IDU as part of the Australian Illicit Drug Reporting System (IDRS) were analysed (2001 - 2004). The rate of morphine prescription per person aged 15 - 54 years increased by 89% across Australia between 1995 and 2003 (from 46.3 to 85.9 mg per person). Almost half (46%) of IDU surveyed in 2004 reported illicit morphine use, with the highest rates in jurisdictions where heroin was less available. Recent morphine injectors were significantly more likely to be male, unemployed, out of treatment and homeless in comparison to IDU who had not injected morphine. They were also more likely to have injected other pharmaceutical drugs and to report injection related problems. Among those who had injected morphine recently, the most commonly reported injecting harms were morphine dependence (38%), difficulty finding veins into which to inject (36%) and scarring or bruising (27%). Morphine use and injection is a common practice among regular IDU in Australia. In some cases, morphine may be a substitute for illicit heroin; in others, it may be being used to treat heroin dependence where other pharmacotherapies, such as methadone and buprenorphine, are perceived as being unavailable or undesirable by IDU. Morphine injection appears to be associated with polydrug use, and with it, a range of problems related to drug injection. Further research is required to monitor and reduce morphine diversion and related harms by such polydrug injectors.

The effects of restricting publicly subsidised temazepam capsules on benzodiazepine use among injecting drug users in Australia.

OBJECTIVE: To assess the effect of a restriction on publicly subsidised temazepam 10 mg capsules upon the injection of benzodiazepines by injecting drug users (IDUs). DESIGN AND PARTICIPANTS: Cross-sectional study of regular IDUs targeting periods before and after the policy change. Analysis of prescription data, including time-series analysis. SETTING: Drug services in the capital cities of New South Wales, Victoria, Tasmania, Queensland and the Northern Territory. MAIN OUTCOME MEASURES: Changes in prescriptions and patterns of benzodiazepine use; harms associated with benzodiazepine use. RESULTS: There was a decrease in temazepam 10 mg capsule prescriptions and a corresponding increase in temazepam 10 mg tablet prescriptions after the policy change. IDU survey data suggested that IDUs continued to inject benzodiazepines and temazepam capsules. The frequency of the injection of capsules after the restriction appeared similar to that before the policy change. There was no change in the frequency of injection of tablets. Most IDUs reported obtaining their benzodiazepines from doctors, with substantial proportions obtaining capsules even after the restriction. About half the IDUs reported purchasing benzodiazepines on the street. Most IDUs who injected benzodiazepines reported injection-related problems. CONCLUSION: Limiting the prescribing of temazepam capsules may have reduced their injection by some IDUs, but additional strategies are needed to reduce the misuse among this group. These may include further restriction of capsule preparations, continued education of doctors and IDUs, and the examination of prescribing practices of individual doctors.
