Question to the Ministry of Justice:

To ask the Secretary of State for Justice, whether his Department has plans to (a) review the effectiveness of substance free living units and (b) make an assessment of the potential merits of extending those units across all prison estates.

As part of the ambitious cross-Government Drug Strategy, we are rolling out a range of interventions to support prisoners off drugs and into recovery. This includes expanding the number of Incentivised Substance-Free Living Units where prisoners commit to remaining free of illicit drugs, with regular drug testing and incentives. We now have over 60 of these wings across the estate, and are aiming to reach up to 100 by March 2025. This will dramatically expand the number of prisoners who have access to these wings. Alongside this we are working to evaluate ISFLs to improve our understanding of the impact they are having and the experience of prisoners on these wings.
