Most offenders have a drug problem when they come into prison. Ensuring that drugs are not available within prison is therefore a major priority for all staff and the system as a whole.

Measures recommended in the Blakey review are now being implemented, including body orifice security scanners, tougher controls on mobile telephones in prison and a comprehensive strategy to deal with staff corruption.
