Question to the Ministry of Justice:

To ask the Secretary of State for Justice, how many people who are currently in prison for drug offences are under 21 years of age.

As of 31 December 2024 (latest available published data snapshot), there were 463 people in prison in England and Wales under 21 years of age with an associated (alleged or proven) drug offence. This is based on the total prison population, and includes those held on remand (both unconvicted, and convicted unsentenced), sentenced and non-criminals. It also includes those held in Young Offenders' Institutions (YOIs).

For those whose offending is driven by a drug problem, we work with health partners to divert them into treatment in the community where appropriate. This includes working to increase the use and strengthen the quality of Drug Rehabilitation Requirements as part of community sentences, which aim to tackle the root causes of offending behaviour through structured treatment and regular testing. Where a prison sentence is appropriate, we focus on supporting people into treatment, and ensuring their environment supports recovery – 81 prisons have an Incentivised Substance-Free Living unit, which provide a dedicated, supportive environment for any prisoner who wants to live drug-free in prison, with regular drug testing and incentives.

Recognising the distinct needs of young adults, HMPPS have developed a Young Adults Custodial strategy to ensure there is a consistent approach amongst prisons to understand this group and support staff in working with them, to better respond to the needs of the cohort.
