Published Wednesday by the American Chemical Society (ACS), the study from Korean researchers developed a multicoloured temporary tattoo that reacts to the presence of GHB, a compound described as “commonly associated with drug-facilitated sexual assault.”

According to the study, the chemicals in the tattoo can detect concentrations of GHB in beer, liquor or coffee, changing colour from yellow to red in order to alert the wearer that their beverage may have been spiked.

“In practice, a wearer could dip a finger into a beverage, touch the drop to the sticker and see the result almost immediately,” the release reads.

The newly developed tattoos not only allow the users to test their drinks discreetly, but also act far faster than some older tests, delivering results in less than a second, rather than minutes.

Researchers also say the results last for up to a month, which can help preserve evidence of suspected tampering.

    They can detect GHB now? Cool, only 10-20 years after it fell out of favor as a date rape drug

        Benzos are about 5x more common than GHB in date rape cases from what I found. Best I can tell is GHB is about half as common as it used to be. Not super common, but ketamine and z drugs are used. Could even be dumping extra shots into drinks.

          Benzodiazepines s makes the most sense, solely from an availability perspective. Lots of people have benzo scritps, not so many doctors handing out GHB

      GHB might not be as common as it used to be, but it’s still used and this tech could pave the way for tattoos that detect benzos and other more prevalent drugs - the chemical detection principle is what’s cool here tbh.
