A new forensic cocaine test uses fingerprints to detect use
A new forensic cocaine test will make it impossible for users to wash their hands of the evidence.
Naturally there is an evolution of technology and drug testing is no different.
Instead of using invasive methods like blood or urine samples to test for substances, a new test uses fingerprints to test for cocaine use.
Not only is it non-invasive, but it is also extremely accurate and only takes a few seconds to complete.
The forensic test was developed by scientists from the Netherlands and UK.
They use chromatography paper to take the sample as part of a technique known as paper spray mass spectrometry.
Researchers reveal the forensic cocaine test to be 99% accurate and is completely unaffected by hand-washing.
The future sees the test able to detect other substances.
Dr Melanie Bailey of Surrey University said: “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.”
“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.”
This breakthrough in testing came as a result of a large scale study of cocaine users where it was seen that certain chemicals are excreted after metabolising cocaine.
Washing your hands clean from substance abuse has just become impossible due to the forensic cocaine test.
