CBS Local — A British study has found that many people may be coming into contact with illegal substances like cocaine and heroine during their day, even if they don’t use drugs.
Researchers at the University of Surrey discovered that 13 percent of drug-free individuals had illegal drugs mixed in with their fingerprints. A study of 50 “clean” subjects and 15 people who had reportedly used cocaine or heroin within the last 24 hours revealed that a person’s unwashed hands were being exposed to several chemicals by just shaking hands or touching objects.READ MORE: Mar-a-Lago search warrant released, reveals FBI seized top-secret classified documents

The scientists added that their tests were able to distinguish between who had been using drugs and who had simply come into contact with a drug-covered item in public. According to the report, the drug traces found on a user were much higher because of the byproducts being released through that person’s pores.MORE NEWS: Time Is Running Out For Biden To Make Key Decisions On Student Loans
“It’s clear that fingerprint testing is the future of drug-testing,” the study’s lead author Mahado Ismail added. “There are many factors that set fingerprint testing apart – it’s non-invasive, easy to collect and you have the ability to identify the donor by using the sample.”
