Summary
Harms related to injecting drug use represent the bulk of the burden attributable to illicit drugs in Australia. In this study we will determine rates of long term cessation of injecting drug use, and relapse, and key drivers of these outcomes such as drug treatment or housing provision. Findings will inform policy and practice around injecting drug use in Australia over the coming decade.

Summary
Cannabis is the most commonly used illicit drug in Australia with an estimated 300,000 individuals with cannabis use disorder in Australia. Treatment presentations for cannabis have more than doubled over the last 10 years, yet there is still no medication to help with withdrawal. This proposal will test pure active ingredients in cannabis in a preparation sprayed in the mouth, to wean individuals from cannabis. This will assist them to complete cannabis withdrawal.

Summary
Chronic pain is a growing and poorly treated global health burden. There is a great need for novel pain therapeutics. We are discovering novel drug targets in pain pathways in the nervous system and new therapeutic molecules that selectively block information flow in pain nerves. Strong pain relieving drugs like morphine also lose their effectiveness after long periods of use. We are finding mechanisms responsible for this thereby providing a rational basis for development of better opioids and ....Chronic pain is a growing and poorly treated global health burden.

Summary
Heroin addiction is an established and increasing problem in developed countries and in many developing nations. Although there have been several new treatments for heroin addiction, methadone maintenance remains the most effective way to minimize the harms associated with heroin addiction. The current research proposal seeks to test a new approach to setting of methadone dose, using monitoring of methadone blood levels, effects and side-effects in determining when to increase doses, and when to ....Heroin addiction is an established and increasing problem in developed countries and in many developing nations. Although there have been several new treatments for heroin addiction, methadone maintenance remains the most effective way to minimize the harms associated with heroin addiction. The current research proposal seeks to test a new approach to setting of methadone dose, using monitoring of methadone blood levels, effects and side-effects in determining when to increase doses, and when to switch to alternative therapies. This provides an objective method of planning treatment that focuses on suppressing heroin use. The potential subjects of the study are the 50% of patients who continue to use heroin regularly during treatment. All will undergo assessment involving measurement of blood levels of methadone, testing of effects and side-effects of methadone, and monitoring of safety. Half will be randomly allocated to usual care, and half to therapeutic drug monitoring, with dose adjustments according to the results of testing. At 3 and 6 months all subjects will undergo repeat test sessions. It is hypothesized that those in the experimental group will be using less heroin (confirmed by hair testing). It is expected that the study will also identify a small group of subjects with genetically different opioid receptors, who will require very high doses of methadone to be stabilized. The study will allow a detailed analysis of how best to monitor dose adequacy; the relationship between withdrawal symptoms, methadone blood levels, and heroin use, and will provide the first clear investigation of the relationship between changes in methadone blood concentration and certain potentially dangerous changes in the electrical activity of the heart. The intended outcome of this research project is a model for a higher standard methadone program that is more effective in reducing the problems of heroin use in our community.Read moreRead less

Summary
This research will evaluate promising new strategies to reduce the harm caused by tobacco, the leading preventable cause of premature death in Australia. This includes evaluation of general population-based strategies, such as public smoking bans, and interventions to help smokers quit smoking, such as new cessation aids and long-term maintenance on pharmaceutical nicotine or low-nitrosamine smokeless tobacco.

Identifying information from these studies will be cross-referenced with National Death Index data to determine participants that died and the dates of their death. This study will be the first in Australia to determine mortality rates over time in a defined cohort of injecting drug users outside drug treatment settings. Studying a defined group overcomes some of the problems associated with mortality rate estimates based simply on the number of injecting drug-related deaths. Although the number of deaths can be found, the number of people at risk of injecting drug-related death is unclear because of the hidden nature of drug use and the dynamic characteristics of drug use and drug markets. The examination of mortality trends among injecting drug users over time can provide insights regarding changes in drug use patterns and markets. For example, this study will examine changes in injecting drug use mortality across periods of high heroin availability in the late '90s and periods of interrupted heroin supply - the heroin 'drought' - from 2000 onwards. In addition, factors related to injecting drug-related mortality can be explored by comparing the characteristics of injecting drug users that died and those that survived, such as drug use and drug treatment histories, co-morbidities such as mental illness and socio-demographic backgrounds. This information can inform overdose prevention and harm reduction strategies by identifying individuals most at risk of injecting drug-related mortality. This study will also draw attention to the significant public health burden of injecting drug use. In addition, by comparing the results from this study with other similar studies from overseas, we can more reliably compare mortality among groups of Australian injecting drug users with their peers in other countries.Read moreRead less

Methamphetamine dependence has been associated with serious physical and mental health problems, including psychosis, depression, stroke and general poor health and wellbeing. Increasing numbers of people are presenting for treatment of methamphetamine dependence and many are experiencing other psychiatric problems like drug-induced psychosis and depression. Currently little is known about people who present for treatment of methamphetamine dependence, including how many have other serious mental health problems that need treatment in their own right. Nor is it known whether the treatment they receive for their methamphetamine use is effective in reducing their drug use or improving their mental health status. The current study will provide much needed information on people seeking treatment for methamphetamine dependence in Australia, including their psychiatric status, and whether the treatment they receive for methamphetamine dependence is effective in reducing their drug use and related health problems or improving their mental health status. These aims will be met by assessing drug use, psychiatric status, treatment experience as well as general health and well being among a cohort of people entering treatment for methamphetamine use in Sydney. Responses to treatment will be assessed at 3 months and 12 months following treatment entry and outcomes will be compared to a group of methamphetamine users not receiving treatment. This is the first study in Australia to assess the effectiveness of treatment that is provided to methamphetamine users in an everyday treatment setting. It is also the first study internationally to focus on treatment outcome for methamphetamine dependence in a community setting.Read moreRead less
