A new fingerprint test can identify whether people have taken or handled cocaine.
Researchers at the University of Surrey explained their methods for accurate drug testing using a fingerprint sample in the Scientific Reports journal. To do this they use a technology known as high resolution mass spectrometry, which can detect traces of drugs and their metabolites in sweat collected from fingerprints.A commercial version of the test is already available from Intelligence Fingerprinting, and is used by Peterborough Council as well as the Wilco Group construction firm.
The team took fingerprints from people seeking treatment at drug rehabilitation clinics who had taken cocaine in the last 24 hours.The participants were then told to wash their hands with soap and water before giving another set of fingerprints. According to the scientists, a molecule produced in the body as a metabolite of cocaine, Benzoylecgonine, could be found in the tests of people even after they had washed their hands.
