The purpose of this review was to examine the available research evidence on criminal justice interventions in Scotland in terms of "effectiveness", (measured by rates of reconviction/reoffending, and reductions in drug use) and costs. The review also recognises the current policy emphasis on "recovery", which requires a wider acknowledgement of the possible mechanisms for measuring "success" and a wider vision for the process of recovery itself. It was undertaken between August and November 2010.
In 2001, the Joseph Rowntree Foundation embarked upon a unique and challenging programme of research that explored the problem of illicit drugs in the UK. The research addressed many questions that were often too sensitive for the government to tackle. In many cases, these studies represented the first research on these issues and the policy implications have been far-reaching. This report outlines the results of the largest independent programme of drugs research of its kind within the UK.
