2007 National Drug Strategy Household Survey: first results presents summary data collected in Australia's most comprehensive national survey of drug use and related issues. Comparisons with previous surveys are presented, along with population estimates of the numbers of consumers of tobacco, alcohol and illicit drugs. Key results on drug-related awareness, knowledge and behaviour are features of this report. This report is the 20th in the Australian Institute of Health and Welfare's Drug Statistics Series. Future reports in the series will cover extended analysis of the 2007 results and a comprehensive summary of major drug use statistical collections. This report and others in the series are useful resources for policy-makers, researchers and professionals interested in drug-related issues.
