The impact of drug treatment on reconviction

Study that compares the differences in the conviction rates of known offenders during the two years before their initial assessment for drug treatment and the two years after.

It presents the results of an analysis of data from the National Drug Treatment Monitoring System and conviction records from the Police National Computer. Data is derived from the Drugs Data Warehouse (DDW). The DDW has been developed by the Home Office, in conjunction with other
government departments and the National Drug Evidence Centre (NDEC) at the University of Manchester, to facilitate access to record-linked data gathered from administrative systems within health and criminal justice in England.
