§ Lord MELCHETTasked Her Majesty's Government:
Why they have statistics showing the proportion of the total quantity of heroin and cocaine seized by Her Majesty's Customs and Excise in 1978 in respect of which interception led to the seizure, or played an essential part, 1584WA but they cannot make available similar statistics relating to cannabis.
§ Lord COCKFIELDThe statistics relating to heroin and cocaine which were given in paragraph 22 of the White Paper Cmnd. 7873 (The Interception of Communications in Great Britain) were compiled as an indication of the value of this facility to Her Majesty's Customs and Excise. No comparable figures are available for cannabis.
