The fingerprint test can show if someone has used heroin, even after washing hands

Advanced technology that can determine if a person has used heroin, even when washing his hands, could help police identify drug users and dealers.

A forensic test developed by scientists in the United Kingdom can distinguish between those who have taken a Class A drug or inadvertently made contact with it by shaking hands with someone else who has handled it.

Researchers from the University of Surrey were able to create the instrument using fingerprints from 10 patients seeking treatment at a drug rehabilitation clinic who had used heroin or cocaine in the previous 24 hours.

Participants were asked to wash their hands thoroughly with soap and water before putting on disposable gloves for ten minutes to make their hands sweat and provide another fingerprint sample.

The same process was carried out with 50 volunteers who declared themselves drug users, which allowed scientists to distinguish substances from each group.

"Our team at the University of Surrey believes that the technology we are developing will make our communities safer and shorten the route for those who need help to overcome their addictions," says Dr. Melanie Bailey, co-author of The Journal of Analytical Toxicology.

"We also believe that technology has reach in other areas, such as confirming whether a patient is taking their medication."

Collective researcher Katya Costa added: "Our results show that this non-invasive and innovative technology is sensitive enough. to identify Class A drugs in several scenarios ̵

"Essentially, our study shows that the process of ha First Wash is important when trying to evaluate whether someone has used a Class A drug."

The team had previously used such technology to reveal signs of cocaine use.

In August, the National Crime Agency made the largest seizure of heroin in Felixstowe, nearly 1.3 tonnes, with a street value of over £ 120 million.
