The prevention of harm from drug use, both legal and illegal, is a major concern to government departments and clinicians throughout the world. Recently, much new research has been conducted regarding global levels and patterns of drug-related harm, on common risk factors with other social problems (e.g. mental health, crime) and on the effectiveness of wide range of intervention strategies. There is a need to summarise and synthesise this new knowledge for use in a range of disciplines. Preventing Harmful Substance Use offers the most comprehensive and up-to-date advice available on the prevention of drug and alcohol abuse. Contributors provide authoritative, science-based reviews of knowledge on their areas of expertise, and make clear recommendations for the future of prevention policy and practice. A final section draws the work together and offers a framework for an integrated science of prevention.

Wendy Loxley is an Associate Professor at the National Drug Research Institute, at Curtin University of Technology in Perth, Western Australia, where she has been employed for fifteen years. Much of her early research career was concerned with addressing the risk of blood-borne viruses to Australian injecting drug users, and she has been involved in a number of large quantitative and smaller qualitative studies exploring this issue. Other research experiences include monitoring illicit drug use among police detainees, the evaluation of community-based approaches to drug law enforcement, and the use of testing and vaccination to prevent hepatitis C and other blood-borne viruses among injectors. She was selected by the Australian Government Department of Health and Ageing to lead the evaluation of the Community Partnerships Initiative which was aimed at the development of community-based approaches to primary prevention of illicit drug use in young people. More recently, she was the first principal investigator on a commission for the Australian Government Department of Health and Ageing which undertook a major literature review of the evidence relating to the prevention of drug use, risk and harm in Australia, She is the first author of the two volumes-Monograph and Summary-which have recently been published from this work.
