A UK law has been changed to enforce random, mandatory drug tests for thousands of people after they are released from prison.
From today (October 3), many former prisoners who are supervised in probation hostels, known as Approved Premises, will be randomly tested for 14 different types of drugs as part of a £1.2 million initiative to "reduce reoffending".
People whose drug habits are directly linked to their crimes will be "legally required to take a urine test up to once a week to prevent their addiction from spiralling into further crimes". All other people will be tested at least twice whilst being supervised in Approved Premises.
