Watch where you put those fingers of yours. A new technology developed in Britain makes it possible to detect THC in your body with 99% accuracy, according to a study published in the Journal of Analytical Toxicology.

Some coroners over in jolly old England have apparently been testing their bodies using the new technology, and the results are pretty legit for finding amounts of four different types of narcotics. In addition to its wondrous talents for detecting THC, the system can also test with 95% accuracy for cocaine, 96% for opiates, and 93% for amphetamines.

Here’s how it works

Sweat is detected off a fingerprint using a device called a Drug Screening Cartridge. This only takes about five seconds. The sample is then analyzed in less than ten minutes using the high-tech circa 1982-sounding device the Intelligent Fingerprinting Reader 1000 unit.

According to the study, the system is also being used in mortuaries to determine causes of death, as well as drug rehabilitation centers and in schools, while officials are looking into implementing it in other environments like airports, prisons, and probation offices.

The system has obvious benefits over drawing blood and asking for cups full of pee. Dr. Paul Yates of Intelligent Fingerprinting commented on this in a press release, saying, “The results from our coroner service trials also clearly demonstrate how our non-invasive fingerprint screen is simple to use, hygienic, and offers an ideal complementary screening approach for the growing number of sectors that require a rapid and flexible drug test.”

David Russell, co-author of the study and Emeritus Professor at the University of East Anglia, U.K., told the Daily Mail how excited he is that it’s now going to be super convenient to test everyone for drugs.

‘This new research highlights how our [device] can screen rapidly for drug use in individuals using a fingerprint sample with a sample collection time of only five seconds, and a total analysis time of ten minutes,” he said.
