HC Deb 12 April 1984 vol 58 c347W
Mr. Soames

asked the Chancellor of the Exchequer how much heroin has been seized at ports of entry to the United Kingdom by year since 1979.

Mr. Hayhoe

The quantities of heroin seized by HM Customs and Excise in each year since 1979 are shown in the following table:

Kilogrammes
1979 40.3
1980 38.1
1981 87.1
1982 183.2
1983 207.3

These figures do, however, include some seizures which were made inland as part of follow-up investigations of smuggling detected at ports and airports or where the drugs were imported by post. The quantity of heroin involved in these seizures is relatively small, but to extract the figures for heroin seized at ports and airports of entry only would require a disproportionate amount of effort and time.
