Question to the Ministry of Justice:

To ask the Secretary of State for Justice, what proportion of random tests returned positive results for psychoactive substances at HMP Isis in each of the past 12 months.

The Government publishes an Annual Digest that provides a range of detailed statistics and measures for prisons and probation for the financial year, including data on drug tests and finds.

The latest publication covering the 17/18 financial year is available at: https://www.gov.uk/government/statistics/annual-hm-prison-and-probation-service-digest-2017-to-2018. Figures on the proportion of positive results for random mandatory drugs tests and the number of incidents where drugs were found for the 17/18 financial year are provided in the table below:

We do not publish monthly breakdowns, however, further information about the proportion of positive results for random mandatory drugs tests can be found by selecting table 7.4 in the ‘Chapter 7 tables – Random mandatory drug testing’ link’.

Further information about the number of incidents where drugs were found can be found by selecting table 9.2 in the ‘Chapter 9 tables – Finds in prison’ link.

These prisons are also part of the 10 Prisons Project which aims to reduce violence in 10 of our most challenging prisons by reducing the supply of drugs; restoring basic decency and providing the training and support for prison officers to challenge the behaviour that drives violence. The project received an initial £10 million funding to improve security and decency, and bolster leadership capability over a 12-month period.
