There is a new drug test on the street which will let police know if you’ve used cocaine within seconds. This is done by testing the suspect’s fingerprints.
According to MixMag:
Designed by scientists from the Netherlands and UK, the paper spray mass spectrometry technique uses a special type of paper that detects chemicals in people’s sweat, created when they metabolise cocaine.
Researchers say the test is 99 per cent accurate and hand washing does not prevent detection. They also say the test may be able to be used to detect other drugs.
This test is considered much less invasive than other means like taking urine, checking saliva or drawing blood. Furthermore, washing your hands won’t make any difference on the test.
“This is a real breakthrough in our work to bring a real time, non-invasive drug-testing method to the market that will provide a definitive result in a matter of minutes – we are already working on a 30-second method,” said Dr. Melanie Bailey of Surrey University. “And, as with previous methods we have developed, it is non-invasive, hygienic and can’t be faked – by the nature of the test, the identity of the subject, and their drug use, is all captured within the sample itself.”
