Fingerprints 'can reveal drug use'


Date: 15/05/2015

Scientists say they can tell if someone has been taking drugs by analysing their fingerprint.

The team at the University of Surrey showed that chemicals produced when cocaine is broken down in the body could be detected in the fingerprint.

They argue the test could be useful in prisons, drug abuse clinics and even for routine testing in the workplace.

However, the current kit may be impractical as it is both the size of a washing machine and very expensive.

Drug-testing normally relies on a fluid sample such as blood, urine or saliva.

However, the researchers believe the fingerprint method would be quicker, less invasive and much harder to fake as the donor's identity would be contained in the fingerprint.
