Journal ArticleDOI
A methodology for illicit heroin seizures comparison in a drug intelligence perspective using large databases.
TL;DR: It emerges from the studies that possible variations in impurity peak areas subject to possible degradations do not influence the C correlation value nor question the already established links, making this solid, reliable and simple method suitable for heroin samples comparison, links profiling and routine use.
Journal ArticleDOI
Development of a harmonised method for the profiling of amphetamines VI : Evaluation of methods for comparison of amphetamine

TL;DR: It was found that the profiling method developed in this work was superior to an existing technique with respect to separating linked and unlinked distances.
Journal ArticleDOI
Drug intelligence based on MDMA tablets data I. Organic impurities profiling.
Céline Weyermann,Raymond Marquis,Céline Delaporte,Pierre Esseiva,Eric Lock,Laura Aalberg,Joseph S. Bozenko,Susanne Dieckmann,Laurence Dujourdy,Frantisek Zrcek +9 more
TL;DR: The statistical methods applied to organic impurities profiles proved to be excellent techniques to differentiate samples from different batches and to highlight operational links between samples to evaluate their potential in the fight against drug trafficking.
Journal ArticleDOI
A study of cannabis potency in France over a 25 years period (1992–2016)
TL;DR: The calculation of THC/CBD ratios in both herbal and resin samples confirms the recent change in chemotypes in favor of high potency categories and was measured in order to evaluate the freshness of French seized hemp.
Journal ArticleDOI
Cocaine profiling for strategic intelligence purposes, a cross-border project between France and Switzerland. Part I. Optimisation and harmonisation of the profiling method.
TL;DR: The harmonisation of the profiling method between the two laboratories had to be ensured and is the subject of ongoing research to improve the gas chromatographic analysis of cocaine samples for profiling.
