Analysis of heroin seized in France.

Abstract

Because of the increase in heroin trafficking in France, it was decided that data on samples of heroin seized in the country would be filed in a computer in the Interregional Forensic Science Laboratory at Lyon. The computer file has made it possible to identify certain physical and chemical similarities among samples of seized heroin. According to the data in the computer file, the colour, purity, diluents etc. of the heroin offered on the street has changed significantly since 1987. The Laboratory will be in a better position to identify the geographical sources of heroin seized in France once samples of seized heroin have been obtained directly from their countries of origin.
