Question to the Ministry of Justice:

To ask the Secretary of State for Justice, if he will make an his estimate of the potential reduction in the (a) cost to the public purse and (b) court workloads of increasing the adoption of community-based rehabilitation in the treatment of alcohol and substance use and addiction reducing recidivism rates.

We are committed to diverting vulnerable offenders with substance misuse needs away from prison or out of the criminal justice system altogether where appropriate. Many people who have committed low-level offences can be managed more effectively in the community, with the right treatment and support to tackle the health-related causes of their offending behaviour, than on short custodial sentences. Public Health England analysis shows that drug treatment reflects a return on investment of £4 for every £1 invested. Offenders completing treatment for drugs or alcohol were also 19 percentage points less likely to reoffend than those that dropped out of treatment.

An evaluation of the impact of being sentenced with a community sentence treatment requirement (CSTR) on proven reoffending was published in 2024 and found that for people who reoffended those sentenced to a drug rehabilitation requirement (DRR) and alcohol treatment requirement (ATR) had fewer reoffences compared to those who received a short custodial sentence.

Our Intensive Supervision Courts (ISCs), which divert offenders with complex needs, including substance misuse, away from short custodial sentences into rehabilitative community sentences, are undergoing full evaluation scheduled for completion in 2028. The evaluation will assess the effectiveness of ISCs on reducing reoffending and their value for money. Published process evaluation findings show early promising signs, whereby some offenders reported reduced substance use and willingness to avoid reoffending.
