Summary
This project shows how relapse to drug seeking can be modulated, and possibly prevented, by novel approaches that manipulate the stability of drug related memories.
Intervention Trial To Reduce Alcohol Related Harms Among High Risk Young Indigenous Australians
Funder

Funding Amount
$392,553.00
Summary
Indigenous Australians experience disproportionately high rates of drug and alcohol harms and young people are particularly vulnerable: over 50% of 10-17 year old juvenile detainees are Indigenous, despite comprising only 2% of the population. There is no reliable evidence about which interventions might reduce these harms. This study quantifies the benefits/costs of combining cognitive-behaviour therapy with a community-reinforcement strategy to reduce substance-related harms among young Indige ....Indigenous Australians experience disproportionately high rates of drug and alcohol harms and young people are particularly vulnerable: over 50% of 10-17 year old juvenile detainees are Indigenous, despite comprising only 2% of the population.

A New Therapeutic Target For Stress-related Relapse
Funder
National Health and Medical Research Council
Funding Amount
$685,266.00
Summary
Relapse and hazardous drinking represent the most difficult clinical problems in treating patients with alcohol use disorders. We have identified a novel system in the brain for the regulation of stress-induced relapse. Successful completion of this project will indicate improved pharmacotherapeutic strategies for the treatment of alcoholism and drug abuse. Given the scale and costs of substance abuse disorders, improved therapeutic approaches will have immediate and sustained impact.
Efficacy Of A 3-month Aerobic Exercise Regime For Restoring 'brain Health' In Heavy Cannabis Users
Funder
National Health and Medical Research Council
Funding Amount
$1,209,221.00
Summary
Over a ten-year period, we, and others have documented the brain and psychological harms associated with regular cannabis use. We have now shown that these harms are not permanent, but can be restored. However, the recovery process takes a long time. This study will build on our extensive work to date and, for the first time, investigate whether a specific form of exercise will cause accelerated and beneficial changes in i) the brain and ii) the daily lives of heavy cannabis users.
Cannabidiol May Protect The Brain Against The Harmful Effects Of Marijuana
Funder
National Health and Medical Research Council
Funding Amount
$974,586.00
Summary
While marijuana holds therapeutic potential, prolonged and heavy use is associated with adverse effects on the brain. However, the key constituents of marijuana (THC and CBD) have been found to have opposing effects on the brain (i.e., harmful vs protective). This project will be the first comprehensive examination of the key question - can CBD protect against marijuana-related brain and psychosocial harms?
The Pharmacology And Toxicity Of Synthetic Cannabinoids
Funder
National Health and Medical Research Council
Funding Amount
$744,808.00
Summary
Synthetic cannabinoids (SCs) have been recently linked to many deaths and hospitalizations but there is limited data available that addresses these issues. We have identified SCs which display unprecedented cannabinoid receptor function, unusual selectivity, and SCs with high activity at cannabinoid receptors. This project will define the role of CB receptors in the actions of SCs, and provide an evidence-based rationale for treating SC overdoses.
In pilot studies, we have found that specific genes are modulated by long-term alcohol intake in a discrete part of the brain that drives habitual behaviours. We will now repeat these studies in post-mortem brain tissue from human alcoholics and age-matched controls. In addition, we will further characterise the functional consequences of long-term alcohol intake within this specific brain region and test new approaches to reduce the urge to consume alcohol.
Investigating The Relationships Between Alcohol And Other Drug Use, Mental Health, Early-life Factors And Life-course Outcomes: Integrative Analyses Of Data From Four Australasian Cohort Studies
Funder
National Health and Medical Research Council
Funding Amount
$448,198.00
Summary
The current study will use a highly innovative approach to pool data from four large and long-running Australasian cohort studies to better understand the developmental precursors and psychosocial consequences of teen drinking behaviours. Findings will provide dramatically improved knowledge of the developmental pathways to teen and young adult drinking and a clearer picture of the total burden of disease attributable to alcohol in an Australasian setting.
A New, Low-cost E-health Treatment For Alcohol Use Disorder Using Mental Imagery
Funder
National Health and Medical Research Council
Funding Amount
$895,032.00
Summary
This project offers the first large-scale test of phone-based Functional Imagery Training (FIT), a new, low-cost way to help people change behaviours using mental imagery, regardless of where they live. The trial addresses Alcohol Use Disorder—a common problem with substantial health and social impacts, comparing FIT with verbal motivational treatments, and testing effects on alcohol use and quality of life over 12 months. Cost-effectiveness and predictions of outcome are also examined.
Substance abuse is a significant social and economic burden upon Australian societies and on societies around the world. Treatment remains problematic due to the multi-layer nature of the disease, difficulties with treatment compliance and less than ideal treatment regimes. The present study aims to improve treatments for alcohol and drug abuse using pre-clinical models to identify and characterize a new brain system implicated in drug-seeking.
