Question to the Ministry of Justice:

To ask the Secretary of State for Justice, in how many prisons there are no illegal drugs.

The National Offender Management Service (NOMS) has a comprehensive drug strategy for prisons, which includes elements to both reduce the demand and supply of drugs in prisons. The success of the strategy is illustrated by the reduction of drug misuse in prisons, as measured by the random Mandatory Drug Testing (MDT) programme, which has declined by 17.5 percentage points over the past 17 years, despite the fact that NOMS is testing for more drugs than previously. Positive rates were 7.8% in 2009/2010 and 6.9% in 2014/2015.

The table below shows the 81 prisons in England and Wales that reported no drug misuse, as measured by random MDT, in at least one month of the 2014/15 financial year.
