The breakthrough that helps test cocaine is 99% accurate in just seconds

With 99% accuracy, this drug testing method is considered an unprecedented breakthrough.

Recently, Dutch experts have announced a method known as "unprecedented breakthrough" in the field of stimulant residue testing, both in terms of accuracy, convenience, and especially speed. test level.

Knowing that currently, drug testing is done through four main methods: urine test, blood, saliva and hair. However, the research team at Surrey University (Netherlands) only needs to consider fingerprints to know if this person used cocaine before.

Each person's fingerprints form several indicator chemicals, including benzoylecgonine or methylecgonine.

Specifically, experts say that when using cocaine, each person's fingerprints form some indicator chemicals, including benzoylecgonine or methylecgonine. These chemicals will remain for a long time, whether or not you wash your hands.

They will use a special type of chromatography (chromatography - a color indicator paper for chemical analysis) . Fingerprints placed here will be separated from the internal compounds, impacting with some chemicals to produce accurate results.

In the study, the group tested 239 fingerprint samples. And the results are really startling, when the right test rate is up to 99%. Although not perfect, but this is clearly an impressive achievement.

Dr. Melanie Bailey - the study's author said that in the experiment, it takes about 4 minutes to know if a person has cocaine use. However, Bailey believes that the number will drop significantly in the future, even if we only take a few seconds.

This is an extremely fast non-invasive test for drug prevention.

"This is really a breakthrough, when it comes to an extremely fast non-invasive test for drug prevention. We are currently improving it to deliver results within 30 seconds. "" Bailey said.

According to experts, this method was evaluated very positively thanks to the speed, hygiene, and very high accuracy. Moreover, the results cannot be counterfeited, and in the future this will certainly be a very good support tool for the police.

It is known that in England and Wales there are about 2.7 million people (aged 16 - 59) who use drugs (data for 2015 and 2016), equivalent to every 12 adults who have 1 child addiction. In addition, there are about 8,500 people each year hospitalized for drug-related mental illnesses, and about 2,500 people die from overdose.
