April 2019 – EA-IRMS: Tracing the geographical origin of cocaine

Cocaine is one of the world’s most widely used narcotics and this widespread use and abuse has resulted in more investigations aimed at tracing the coca cultivation regions and identifying exportation routes of the illicitly isolated cocaine.

Despite the complexities evident, it has been shown that isotope fingerprints in seized cocaine provide an enhanced insight that allows the coca cultivation region to be identified when combined with trace alkaloids.


This application note is a summary of the work by Mallette et al (2016) and focusses on the isotope fingerprint data from coca leaves and seized cocaine samples.
