Summary
The use of amphetamines has increased in Australia in the last decade. According to the 1998 National Household Survey, lifetime use of amphetamines has increased by over 50% from approximately 6% in 1995 to approximately 9% in 1998; recent use (last 12 months) has increased from 2% in 1995 to approximately 4% in 1998. This increase appears to be even greater in Queensland, the site of the proposed study, which has seen both an overall increase in the use of illicit drugs and an increase in the ....The use of amphetamines has increased in Australia in the last decade. According to the 1998 National Household Survey, lifetime use of amphetamines has increased by over 50% from approximately 6% in 1995 to approximately 9% in 1998; recent use (last 12 months) has increased from 2% in 1995 to approximately 4% in 1998. This increase appears to be even greater in Queensland, the site of the proposed study, which has seen both an overall increase in the use of illicit drugs and an increase in the use of amphetamines specifically. The most recent estimate of the number of current users (use within the last 12months) aged 14 years and over in Queensland is 85.5000. This compares to 17.000 recent heroin users in the same age range. Of particular concern is the increase in the use of methamphetamine, which has high abuse potential producing euphoric effects that are similar to, but longer lasting than, those of cocaine. Also of concern, given the increasing purity and availablity of methamphetamine, is the link between amphetamine use and psychosis, a psychotic disorder characterised by sensory hallucinations, paranoid delusions and a loosening of associations. Despite this well established link, there are surprisingly few studies in which the course and onset of amphetamine psychosis has been studied. In this reseach the relationship between subclinical features of psychosis, measures of psychosis proneness and other factors implicated in the development of schizophrenia will be investigated in a prospective cohort in which amphetamine users will be followed up once per month for twelve months.Read moreRead less
Longitudinal Study Of Modifiable Influences For The Development Of Harmful Young Adult Alcohol Use And Related-problems.

Summary
Young adulthood is a time of high vulnerability for alcohol use problems that are the major preventable contributor to death and injury in this age period. This 5-year project will identify modifiable influences in adolescence and young adulthood that contribute to harmful alcohol use. A cohort of almost 3,000 young people initially recruited in Victoria in 2002 (aged 11 to 15) will be followed for two further waves of data collection in 2010-11 (age 19 to 23) and 2012-13 (age 21 to 25).

Summary
Cannabis is increasingly widely used and abused by young people. Use in young people with schizophrenia is even more extensive. There is some suggestion that this drug use is a result of their illness, ie to reduce unpleasant symptoms or feelings. Equally the drug may contribute to their psychosis. This study aims to assess the degree to which psychosis may be caused by cannabis use in vulnerable young people.
Diversion And Misuse Of Stimulant Medication For ADHD Among Illicit Psychostimulant Users

Funding Amount

Summary
The practices of diversion and misuse of pharmaceutical stimulants give serious cause for concern due to their potential to increase the risk of drug toxicity, dependence, and serious adverse health consequences. These practices may be particularly harmful among illicit psychostimulant users. This will be the first to study the nature of diversion and misuse of pharmaceutical stimulants among illicit psychostimulant users and the first to examine the associated correlates and consequences.

Alcohol problems continue to pose a significant burden across many areas, including the physical and mental health of the individual, and the wider implications for families, health systems providing care, and society as a whole.

Despite the existence of a variety of therapies including in- and outpatient programs and anti-craving medications, people continue to struggle with this problem. Increased craving for alcohol is a major factor in ability to adhere to treatment, rate of progress, and long-term maintenance of change. Whilst current medications target craving, they provide only short-term symptom relief, and not all people find them effective. Cravings are both distracting and distressing during treatment, and increased craving often predicts treatment drop-out and relapse. This project evaluates a new treatment for alcohol misuse: CARM - Craving for Alcohol: Reduction and Management. This 8-session enhanced Cognitive-Behaviour Treatment (CBT) focuses on teaching people new skills to manage and reduce cravings, and is based on a new theory of craving that has strong research support. The study compares 4 groups: CARM; a more traditional CBT treatment for alcohol problems [motivational interviewing, problem solving for high-risk situations, and relapse prevention]; plus two brief interventions [Motivational Interviewing plus Self-Monitoring, and Self-Monitoring alone] both followed by CARM after an 8 week delay. All participants are able to set their own goals of abstinence or reduced use. Expected outcomes: all participants will learn effective skills to manage their alcohol use, resulting in significant reductions in alcohol consumption and fewer problems from alcohol use; however, those receiving CARM will find it easier to manage cravings during treatment, and will make faster progress and show less treatment drop-out. It is also anticipated that participants in CARM will show better long-term maintenance of treatment gains.Read moreRead less

Summary
Hopelessness, depression and suicidal ideation are common among people who misuse alcohol and other substances. A general relationship between alcohol-substance abuse and self-harming - suicidal behaviour has been recognised for decades. From the point of view of diagnosed substance abusers there is a correspondingly high incidence of suicide and self-harm.

A general relationship between alcohol-substance abuse and self-harming - suicidal behaviour has been recognised for decades. From the point of view of diagnosed substance abusers there is a correspondingly high incidence of suicide and self-harm. The lifetime risk for suicide in alcohol dependence is higher than for schizophrenia or affective disorder. Despite the public health and personal burden associated with suicidality, the general lack of skills and focus on management of self-harm in specialised drug and alcohol services is of great concern. In this study, all patients attending drug and alcohol services will be screened for suicide risk, and offered a comprehensive psychological treatment to reduce suicide risk and the use of alcohol and other substances.Read moreRead less
