Prisoners are subject to both random and targeted mandatory drug testing. The figures1 for contracted out prisons in each of the last five years are given in the following tables. Some prisoners will have been tested more than once in any year.

Notes: 1. Information has not been provided for the total number of tests that tested positive as this can be calculated by using the percentage of positive tests and the number of tests carried out. 2. There are two types of MDT—random and targeted. The random MDT positive rate is one of the prison service's key performance indicators. Initially, 10 per cent. of every prison's population was tested each month under the random programme, but since 1999 prisons with a population of 400 or above have tested 5 per cent. The reduced level of random testing was expected to be compensated for by an increase in targeted testing. Due to contractual obligations, some contracted out prisons have continued to test at the 10 per cent. random level.
The information requested is not held centrally and could be obtained only at disproportionate cost. Records of passive drug dog indications and subsequent drug finds are held locally, so to obtain the information required would mean consulting all prisons that are operating or have operated passive drug dogs.
