Police will be able to tell if someone has used cocaine within seconds simply by taking their fingerprints after a new forensic test was developed by scientists in the UK and the Netherlands, according to The Independent.
The researchers found that using a special type of paper to take the fingerprints enabled them to detect these metabolites with 99 per cent accuracy. Hand-washing does not prevent detection. The technique, developed by scientists at Surrey University working with the Netherlands Forensic Institute and Intelligent Fingerprinting, a private firm, may also work for other drugs.
Currently drug tests involve taking samples of blood, saliva or urine and for now its now know when will the police start using this type of testing.
