Scientists have figured out a way to use fingerprints to monitor drug use, which could bring an end to urine, saliva and blood testing.

Researchers used a chemical analysis of people’s prints to determine whether they had ingested cocaine, as part of a study in the journal ‘Analyst’.

Scientists are already able to use fingerprints to test whether a person has touched cocaine but this latest study takes things one step further.

Researchers predict that the findings could lead to portable tests within police departments within the next decade, as according to Gizmag the test is “non-invasive, hygienic, and impossible to fake, with the identity of the subject captured in the fingerprint itself”.

Researchers used a technique known as mass spectrometry to search for the signs of cocaine use in the fingerprints.

The study’s lead author from the University of Surrey, explained:

When someone has taken cocaine, they excrete traces of benzoylecgonine and methylecgonine as they metabolize the drug, and these chemical indicators are present in fingerprint residue.

Several companies are now reportedly working on a way to make the testing portable and cheap, so be careful next time you’re out clubbing!
