Researchers examined outcomes across 13 English police forces and more than 62,000 criminal incidents over the past four years, finding that people whose cases were dealt with through decriminalisation-style diversion schemes were a third less likely to reoffend than similar individuals prosecuted for drug possession. A number of police forces in England use formal diversion schemes for people caught in possession of drugs, notably Durham, the West Midlands and Thames Valley. But many forces, even if would-be offenders are not often sent to prison for simple possession offences today, still officially take a law-and-order approach towards illegal drug use. Prof Alex Stevens , the acting director of the University of Sheffield’s Centre for Criminological Research, who led the research, said: “The evidence is now strong enough that all police forces can be confident in adopting and expanding diversion schemes for people caught in possession of drugs.” The researchers who conducted the four-year, first-of-its-kind study, funded by the Cabinet Office’s evaluation accelerator fund, are working with the National Police Chiefs’ Council (NPCC) and the College of Policing to help police forces countrywide to adopt police-led drug diversion. Quantitative data was collected over four years on a cohort of people who were contacted by police forces between October 2021 and September 2022. Commander Alison Heydari, the NPCC lead for out-of-court resolutions (OOCRs), said the study highlighted the effectiveness of diversion. “Through the ‘national OOCR strategy’, there is a clear commitment to ensuring that eligible individuals are consistently offered appropriate alternatives to prosecution, helping to prevent reoffending while also addressing disparities in outcomes,” she said. The researchers, however, found that diversion was being used far less than it could be, even in police forces with established diversion schemes, with only a minority of eligible cases diverted as officers chose not to divert eligible offenders. “Police forces now have an opportunity to reduce their costs – and pressure on the courts – by making more use of diversion,” said Stevens, who quit the governm
