Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, how much has been spent by his Department on drug rehabilitation for (a) men and (b) women in prisons in (i) England and (ii) Wales in each year since 2010.

The information requested on what drug rehabilitation programmes are operated, the budget, number of prisoners using them and the location of the prison is either not collected centrally or not available in the format requested.

NHS England estimates that it spends approximately 20% of all prison healthcare spending on substance misuse services. In the financial year 2016/17, NHS England allocated approximately £405 million for all health expenditure in the adult prison estate. Comparable data is not available prior to 2013/14 when NHS England became operational.
