Summary
A high proportion of smokers indicate a desire to stop smoking and report having made attempts to quit. However, most attempts are not successful and new methods are needed to support motivated smokers and improve success rates. This project evaluates the use of text messages to deliver advice and support to smokers motivated to stop smoking. We aim to understand if and how this promosing new intervention helps smokers to quit.
An Open-label Randomised Pragmatic Policy Trial Of Nicotine Products For Short-term Cessation Assistance Or Long-term Substitution In Smokers.

Funding Amount

Summary
Many smokers who try to quit fail in their attempt. Medicinal nicotine is currently only used as a short-term quit aid. This trial will test if offering smokers the option of using these products as long-term substitutes for cigarettes will help more smokers to successfully quit. We will also determine if offering smokers low toxicity smokeless tobacco and electronic nicotine devices in addition to medicinal nicotine products further increases the number of smokers who quit successfully.
Public Health Policies And Interventions To Reduce Tobacco-related Harms Among Socially Disadvantaged Populations And ‘low Probability Quitters’

Summary
Tobacco continues to be a leading cause of preventable death and disease in Australia. Those who are socially disadvantaged are at higher risk of smoking, which contributes to the health gap between the rich and poor. This research will provide evidence for policy makers on interventions which could reduce smoking among the most disadvantaged in society. It will also examine whether less harmful nicotine products could a reduce health risks in smokers who find quitting difficult.
A Novel Knockin Model To Test The Role Of Nicotine Acting On Alpha4 Acetylcholine Receptors In Complex Behaviours

Summary
Cigarette smoking is the single largest preventable cause of death and disease in Australia and worldwide. Nicotine contained in tobacco products acts on brain nicotine receptors, which plays an intrinsic role in addiction. One type of receptor for nicotine found in regions of the brain associated with drug-seeking behaviour is called alpha4 nicotinic receptors. We have made a mouse with a mutation in this nicotine receptor to study nicotine addiction and anxiety.
Understanding The Impacts Of Vaporised Nicotine Products On Smoking In Australia

Summary
Vaporised nicotine products (e.g., e-cigarettes) are widely used in Australia, even though possession of the nicotine fluid without a permit is an offence. They are primarily used by smokers as a means of quitting. However, there is concern about their potential attractiveness and uptake by non-smokers. The aim is to identify how these products might be used to both maximise smoking cessation and minimise nicotine use, especially smoking uptake by non-smokers.
Evaluating The Efficacy Of An Integrated Smoking Cessation Intervention For Mental Health Patients: A Randomised Controlled Trial

Funding Amount
$1,442,270.00
Summary
Smoking rates are 2 to 4 times higher among people with a mental illness than among the general population. There is an imperative to identify effective cessation interventions that can be systematically provided to smokers with a mental illness. The aim of this project is to undertake a rigorous test of the efficacy of a smoking cessation intervention for smokers with mental illness; where intervention commences in the hospital inpatient setting and extended support continues post-discharge.

Summary
We will examine the practical feasibility, ethical and public acceptability, and likely cost effectiveness of a number of different ways of reducing tobacco smoking and the harm caused by smoking in Australia. These policy options will include: (1) more restrictive policies towards tobacco products (such as prohibiting tobacco smoking and creating a government monopoly on the manufacture and supply of tobacco); (2) encouraging smokers to switch from smoking cigarettes to less harmful ways of usi ....We will examine the practical feasibility, ethical and public acceptability, and likely cost effectiveness of a number of different ways of reducing tobacco smoking and the harm caused by smoking in Australia. These policy options will include: (1) more restrictive policies towards tobacco products (such as prohibiting tobacco smoking and creating a government monopoly on the manufacture and supply of tobacco); (2) encouraging smokers to switch from smoking cigarettes to less harmful ways of using nicotine, such as using nicotine patches or gum ; (3) using new biotechnologies to improve smokers chances of quitting (e.g. genetic screening of smokers to select the most effective way of helping them to stop smoking and vaccinating ex-smokers against the effects of nicotine); and (4) new biotechnologies that may prevent nonsmokers from beginning to smoke (e.g. vaccinating nonsmokers against the effects of nicotine) or reduce the chances of their developing tobacco-related diseases (e.g. screening the population for genes that predict an increased susceptibility to nicotine dependence and tobacco-related diseases). The project will provide important information that will assist government in formulating policies to reduce the rate of cigarette smoking in the Australian population below current levels.Read moreRead less

Problems associated with the long-term use of tobacco and the abuse of alcohol permeate society. The development of effective programs for both the prevention and cessation of tobacco use and alcohol abuse requires an understanding of the natural history of the use of these substances. Most studies of the natural history of tobacco and alcohol use have followed individuals through secondary school and into the early 20s.

The development of effective programs for both the prevention and cessation of tobacco use and alcohol abuse requires an understanding of the natural history of the use of these substances. Most studies of the natural history of tobacco and alcohol use have followed individuals through secondary school and into the early 20s. These studies tell us about the psychosocial influences on these behaviours but not about the role of genes on initiation and escalation of substance use. Yet recent advances in the neurophysiology of nicotine and alcohol receptivity and molecular genetics research suggest that genes play at least some role in determining the use of alcohol and tobacco. This proposal is for funding to continue a study designed to investigate the natural histories of alcohol and tobacco use among a sample of 1400 young Australian twins from adolescence to adulthood (early 30s). The study involves a telephone survey of these twins about their smoking and drinking behaviours, and among other things, their attitudes about smoking and drinking, the use of tobacco and alcohol by family and friends and presence of smoking bans at home and work. Because this study explicitly examines the influence of social and psychological factors on tobacco and alcohol use we will be able to determine the relative contribution of genes and psychosocial factors in tobacco and alcohol use. The proposed study is unique in its use of twins, its longitudinal design and its integration of genetics into psychosocial models of behaviour. The results of this study will help to clarify the role of genes in the development of tobacco use and alcohol abuse. Importantly the results of this study will help to identify those social and psychological factors that increase the likelihood of a genetically susceptible individual becoming dependent on nicotine and-or abusing alcohol.Read moreRead less
Nicotine abuse is the single greatest preventable risk factor for physical illness and death in Australians. Our understanding of the neural and cognitive mechanisms that underlie the transition from use to dependence is yet to be understood. The current proposal investigates the neural mechanisms underlying cognitive control, critical to self-control over the impulse for drug rewards, in non-dependent and dependent nicotine users.
