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
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.
I mean, you are free to go into the lab and research your own selectively recognising, non-toxic, stable, easy to use chemical. Shouldn’t take you long since you are such an expert.
I mean I am an expert in this sort of thing and I agree this is kind of a dumb idea. The innovation here is not the production of a color changing indicator, but rather putting it in a temporary tattoo. The indicator has existed for some time, and is well studied. The temporary tattoo thing is cool, but I question whether the additional cost and complexity of using it this way is worth it over existing technology, such as paper test strips. The criticism that it only tests for a specific, not commonly used drug is also valid because even though it is complicated to make something that tests for multiple drugs is far more complicated, not testing for the most commonly used drugs can create a false sense of security. It’s like if you went to a big concert and security was outside only checking for swords and knives and not guns. Yeah those things are also dangerous but it’s not the biggest threat. To further the analogy, imagine if a decent subset of people believed the security guards were checking for guns but weren’t. That would be pretty bad right? I can’t imagine the anti date rape temporary tattoo wouldn’t be misunderstood to test for a wide variety of drugs or at the very least the most common ones by at least a decent chunk of people trying to use it.
TIL that only experts in a field can offer criticism of that topic!
You completely missed the point.
You complained in a pretty smug way about science not being fast enough.
Problems often don’t have easy solutions or they would have been already found. Finding solutions which fulfill all or at least most requirements takes time. If you don’t like that, start contributing. But just sitting there and complaining that it doesn’t work like a video game where X research happens after Y time is just stupid.
Criticism is fine. But you just wanted to feel smug as e evident by the way of your comment.
Thanks for telling me what I said. I keep learning new things
I literally review research in my day job. I’ve never had someone present a study and say “we want to investigate this idea that’s waning in popularity instead of being on the frontier of science”
Then you should know that science advances mostly in small steps instead of big ones? And that additional data helps supporting other ideas, so that other researcher can build on those?
From a quick search, wearable tattoos for drug testing are a pretty recent development. And often it’s not only about the what, but especially in an early field about the how. Other researcher can look into this and get ideas for how to incorporate the fundamentals for other drug testing compounds.
Is this contribution going to save the world or stop all date rape drugging? No.
Its still heavily used according to somewhat recent studies afaik. I dont remember where i read it sadly.
What do people use now? Couldn’t be ex or Molly. Xanax? Idk I’m still in 1991.
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
