The Arrestee Survey is the first nationally-representative survey of drugs and crime among individuals arrested in England and Wales. It provides a measurement of self reported drug misuse among a sample of individuals arrested in England and Wales. The link between drug and/or alcohol consumption and criminal offences leading to arrest is also examined, as are associations between self-reported drug use and wider offending behaviour. Three sweeps of the data have been collected in 2003-04, 2004-05 and 2005-06. This report presents the findings from the 2005-06 survey, as well as highlighting any significant changes in results over the three sweeps. Only statistically significant, and substantial, changes over time are included in this report. Any other apparently substantial differences in tables are not statistically significantly and as such cannot be taken as showing real change.
