This report extends the analysis presented in '2004 National Drug Strategy Household Survey: first results' by providing more detailed information on drug use prevalence, drug-related behaviours and incidents, and support for drug-related policy and legislation. The report features analysis relating to young people--reflecting the inclusion in the 2004 survey of 12-13-year-olds--and new material on mental and physical health, also included for the first time in 2004. This report, along with others in the Drug statistics series, will be a useful resource for policy-makers, planners and researchers interested in drug-related matters.
