§ Mr. Mellor
Forensic science service figures for the number and weight of seizures of crack in 1990, by police region and month of analysis, are set out in the table. The estimated street value of crack varies according to time and place and is not routinely assessed for each seizure. The estimated current street value of the total amount seized in 1990 to date (258.79 grammes) is in the region of £32,500.
There have been no known seizures of crack by Her Majesty's Customs and Excise in 1990 so far. Crack is not generally imported but produced in the United Kingdom from cocaine.
