HC Deb 08 July 1985 vol 82 c320W
Sir Brandon Rhys Williams

asked the Secretary of State for the Home Department what is currently the time taken by the police forensic science laboratories to analyse samples of products suspected of containing cannabis, heroin and cocaine.

Mr. Giles Shaw

Information is not available on the time taken to complete analyses in different types of drug cases in either the six Home Office forensic science laboratories or the Metropolitan police laboratory. The average time currently taken in all drugs cases, of which cannabis, heroin and cocaine form the major part, varies as between laboratories from 17 to 32 days.
