Summary
Prevention and treatment of addiction to stimulants such as methamphetamine is imperative for community health and safety. This fellowship will enable me to apply my expertise in impulsivity and addiction to identify people at risk of increasing methamphetamine use and to develop and evaluate cognitive training therapies that will empower people with methamphetamine related problems to control their drug use. Outcomes include a risk identification and triage tool and three novel therapies.

Summary
Drug addiction is a major health and societal problem in Australia. It is consistently associated with an adverse impact upon individual users, their families, and communities. Prolonged drug use is associated with increased rates of physical problems (e.g., cardiovascular disease), mental health problems (e.g., depression and anxiety), and criminal involvement (e.g., property crimes and incarceration). A defining feature of drug addiction is that it is a chronically relapsing condition. Between ....Drug addiction is a major health and societal problem in Australia. It is consistently associated with an adverse impact upon individual users, their families, and communities. Prolonged drug use is associated with increased rates of physical problems (e.g., cardiovascular disease), mental health problems (e.g., depression and anxiety), and criminal involvement (e.g., property crimes and incarceration). A defining feature of drug addiction is that it is a chronically relapsing condition. Between 60-80% of addicts attempting to give up drug taking will relapse to drug taking. The behavioural and brain mechanisms which underpin this persistent propensity to relapse are largely unknown. This project studies the behavioural and brain mechanisms for relapse to drug addiction. This project uses a well validated animal model of drug taking to ask why relapse occurs. It will identify some of the environmental antecedents to relapse and the brain mechanisms which mediate relapse. As such, this project will project will provide important information about relapse to drug addiction and may help identify targets for therapeutic intervention and possibly disrupt the addictive cycle.Read moreRead less
Drug addiction is a major health and societal problem in Australia. Relapse is among the most fundamental problems for addicts. This project studies the behavioural and brain mechanisms for relapse to drug seeking. It studies why relapse is more likely in some places than others; the brain mechanisms for this contextual control over relapse; and how relapse to seeking drug rewards is similar to and different from relapse to seeking non-drug rewards.

Understanding The Methamphetamine Epidemic And Its Implications For Service Provision And Harm Reduction: The VicMeth Cohort

Funding Amount
$1,270,774.00
Summary
The Victorian methamphetamine epidemic has received extensive media coverage highlighting the devastating impact of the drug and resultant public concern. We will follow up a cohort of 800 methamphetamine smokers from metropolitan and regional Victoria bi-annually for a period of 5 years to determine the natural history of methamphetamine use to inform optimal intervention strategies and arrest the increases in harm observed in Victoria recently.
Driving Change: Using Emergency Department Data To Reduce Alcohol-related Harm

Funding Amount
$1,468,026.00
Summary
The proposed project is a system change within partner emergency departments, providing them the information and tools to act on both risky alcohol consumption in individual patients and the sources of alcohol in the community which cause the harm they experience. Most importantly, the proposed public health interventions act as a tool for emergency departments to regularly raise awareness with the public and policymakers regarding the impact of alcohol on patients, clinicians and hospitals.
Increasing The Capacity Of Community Pharmacy For Screening, Brief Intervention And Referral For Treatment Of Pharmaceutical Opioid Use Disorders

Funding Amount
$177,197.00
Summary
Pharmaceutical opioid dependence is a growing problem. There are effective treatments available, yet few people who need treatment receive it. Currently, pharmacists receive little training on substance use disorders, yet are in contact with almost every person likely to develop problems with pharmaceutical opioids. This project will take an innovative approach to involve pharmacists in identifying those developing problems with pharmaceutical opioids and referring them to treatment.

It is consistently associated with an adverse impact upon individual users, their families, and communities. It is a chronically relapsing condition for which few, if any effective prevention and treatment strategies exist. Moreover, why an individual initiates and maintains heroin taking remains unclear. Stress and negative emotions have a strong impact on heroin use. Stress may drive some individuals to start using heroin, stress increases the pleasurable effects of heroin and stress increases the aversive effects of heroin withdrawal. These effects will encourage addiction and discourage addicts from seeking treatment. Stress can also cause an otherwise drug-free individual to relapse to heroin addiction despite having been drug-free for some time. In this project we will study why stress has such a large impact on heroin addicts and heroin addiction. We will test the hypothesis that heroin use actually produces profound alterations in the neural network in the brain which controls responses to stress. This project uses a simple animal model of heroin addiction whereby rats are injected with morphine to study the regulation of several genes which are important in responding to stress. We will also study how this exposure and changes in gene expression alter neurobiological, cardiovascular, and behavioural responses to stress. This project will identify parts of the brain that are altered during heroin addiction, and will also identify why heroin addicts are more vulnerable to stress than the general population. Therefore, this project will help us to identify targets for therapeutic intervention (both psychological and pharmacological) and possibly disrupt the addictive cycle.Read moreRead less

Summary
Drug abuse remains one of the world’s leading health care problems and the current drugs available to treat drug addiction are largely ineffective. This project aims to investigate the potential of a novel therapeutic target for the treatment of drug addiction with has the capacity for substantially reduced off-target effects.
Alcohol,tobacco, Illicit And Prescribed Drugs: Prospective Cohorts And RCTs

Funding Amount

Summary
This research addresses the important areas of infant, childhood, adolescent, adult, and family well-being and the effects of exposure to tobacco, alcohol, and illicit drug use. The impacts of these substances on psychological, cognitive, vocational, and physical well-being remain poorly researched. A related set of research projects is aimed to build the evidence base for effective intervention to prevent or manage psychological and cognitive sequelae from such exposure.
