Question to the Ministry of Justice:

To ask the Secretary of State for Justice, what steps he is taking to prevent new psychoactive substances being used among the prison population.

We take a zero tolerance approach to drugs in prison and there are already a range of robust measures in place to detect drugs, including the use of search dogs and intelligence-led searches.

We recently introduced tough new laws which will see those who smuggle packages over prison walls, including new psychoactive substances, face up to two years in prison. We are piloting mandatory drug testing for new psychoactive substances from this month, and intend to roll it out to all prisons by April 2016.

Those who involve themselves in the distribution of drugs in our prisons should know that they will face prosecution and extra time behind bars.
