Concordance between self-reported drug use and findings in hair about cocaine and heroin

Laboratoire d'Expertises Toxlab, 18 rue André Del Sarte, 75018 Paris, France

Abstract 

We have presented the results concerning 135 judicial expert opinions over a 3-year period. We have compared the measured levels in hair of 6-acetylmorphine (6-AM) and of cocaine with the habitual use declared by the consumers. This allows us to propose three levels (low, medium, high) of consumption in relation to the level of the 6-AM marker found in hair for the consumption of heroin, and the level of cocaine as a marker for the cocaine intake.

Keywords:  Cocaine, Heroin, Hair, GC-MS, Consumption
