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.

That was a big part of my criticism - it is convoluted to use and remember, and it kind of does scream that because you still have to do something weird and potentially noticeable to do the test. I am not criticizing the fact that tests that are designed to be subtle exist. I just think this particular one is kind of a stupid idea. There’s a reason it’s being reported on by a chemistry journal rather than a medical or business journal - it’s simply not a viable product when compared to existing technologies, even if it’s a cool technology.
