Verification of your drink for medicines no longer needs to feel like a scientific experience. South Korea scientists have created a new solution, a temporary tattoo sticker that instantly detects falsification. This simple sticker works quickly, remains discreet and offers surprisingly powerful protection.
At first glance, it looks like ordinary skin art. In reality, it works as a chemical sensor. The sticker detects GHB (gamma hydroxybutyrate), a drug commonly used to increase drinks. When even a small amount of GHB affects the sticker, the design goes from yellow to red in a second.
This breakthrough gives revelers, students and anyone in a social environment a quick and subtle way of staying safe. Better still, it is easier to use than any band, swab or traditional test card.

How the GHB detection tattoo sticker works
The use of the tattoo is simple. Apply the sticker to your arm, your wrist or your hand before leaving. Later, if you are not sure of your drink, just dip your finger, then touch this drop with the sticker. A color change in red means that the drink contains GHB. Unlike other tests that can take several minutes or require intimacy to use it, this method is quick and not very profiled, perfect for crowded clubs, bars or household celebrations.

This drug detection tattoo sticker works in real situations
The science behind this sticker is impressive. It is made from a flexible material called polydimethylsiloxane (PDMS), and inside are gels containing a chemical called Bhei. This is what reacts to the GHB and triggers the color change. The researchers tested the stickers on drinks like whiskey, beer, vodka, soju and even coffee. They still worked after being stretched, twisted or exposed to water. The detection limit is so sensitive that it can catch as little as 0.01 micrograms of GHB per milliliter.
What is artificial intelligence (AI)?
Even better? If your sticker changes color, the red result remains visible up to 30 days after having removed it. This means that you could potentially use it as proof if necessary.
Scientists shared these results in an article published in the journal ACS Sensors.

Drink Dishing is a serious problem that is difficult to see, difficult to stop and difficult to prove. But this tattoo type sensor changes this. He adds a fast, subtle and science protective layer. Other versions may arrive in the future to detect other drugs such as ketamine or rohypnol. But even now, this unique solution could help prevent dangerous situations before starting.
