Question to the Ministry of Justice:

To ask the Secretary of State for Justice, what proportion of prisoners tested positive for illegal drugs on arrival and during their time in custody in the latest period for which data is available.

We recognise that the availability and use of drugs in prisons is too high. Tackling this is a priority in order to reduce reoffending, and improve the safety of our prisons. To drive down supply of drugs, we are investing over £40 million in physical security measures this financial year. This builds on the range of specialist equipment prisons already use to intercept contraband, including X-ray body scanners, airport-style Enhanced Gate Security, and baggage scanners.

We must also address the demand for drugs which drives this illicit market. We work closely with health partners to identify prisoners with a drug problem and support them into treatment. To create the environment and incentives for prisoners to make the right choices, we have funded Incentivised Substance Free Living Units in 85 prisons. Prisoners on these units sign a behaviour compact, agree to be regularly drug tested and can access enhanced opportunities compared to a standard wing. Alongside this, we are working to increase access to mutual aid fellowships in prison, which can provide vital ongoing support for people in recovery.

The information requested regarding the proportion of prisoners testing positive on arrival and during their time in custody can only be provided at disproportionate cost.
