Abstract EN:

Illicit drugs have always been used by humans. With scientific progress, new drugs appear each year. At the present time, in France, Ecstasy is the most widespread illicit synthetic drug. The term Ecstasy generally refers to tablets containing 3,4-méthylendioxy-methamphetamine (MDMA). In order to struggle against traffics of drugs of abuse, many methods can be employed. In this study, 13C/12C and 15N/14N ratios of MDMA samples were measured by isotopic techniques, in particular by using a Gas chromatograph-combustion-isotope ratio mass spectrometer (GC-C-IRMS). The aim of such analyses was to confirm that links exists between precursors, synthetic pathways and MDMA, and in the same way to establish links between drug seizures. . .
