Alternatives to Criminalisation: Police Drug Diversion

Discover how innovative drug diversion schemes are changing the way police respond to drug-related offences in England.

This research project is an evaluation of the effectiveness and cost-effectiveness of police-led diversion (PDD) schemes for drug-involved suspects. A team of academic, policing, health and service user partners are evaluating PDD schemes that are already operating in three areas; Durham, Thames Valley and West Midlands. People on the schemes are assessed, then referred to education, treatment or support (as needed) with an ‘out of court disposal’, like a warning, which does not create a criminal record.

Researchers are using data already collected by the police, NHS, and drug treatment services to assess the impacts of diversion on crime, hospitalisations and engagement with drug treatment. They are comparing the outcomes for people eligible for diversion in the three areas to the outcomes of similar people in matched areas which do not yet use PDD (Humberside, Hampshire and Greater Manchester). In order to learn how PDD schemes work in practice, the team have carried out interviews and focus groups with the people who work with these schemes, including police officers, drug treatment providers, service users and their families. We are also examining what the equitable the effects of PDD are (e.g. by ethnicity and gender).
