HC Deb 29 October 1984 vol 65 c817W
Mr. Kilroy-Silk

asked the Secretary of State for the Home Department what are the names of the prisons where cannabis plants have been found; and how many plants were found.

Mr. Mellor

There have been isolated incidents in which cannabis plants have been found in prison establishments. But no record is available centrally of each establishment where such a discovery has been made, or of the number of plants involved.
