In nightlife spaces, drink spiking is dangerously common and nearly impossible to detect. Drugs like GHB and Ketamine are odorless, tasteless, and act fast. While the threat is widespread, women and LGBTQ+ individuals are most affected.
Yet the burden of protection still falls on individuals, when it should be shared.

Safety should be a collective responsibility.

Idea
A drug-detecting entry stamp that glows when a drink has been spiked.
It transforms a routine club ritual into a powerful, visible safety tool creating a moment of protection that’s simple, seen by all, and provided by the venue – so it’s not just on you.

The stamp
Bombay Sapphire presents: Glow Means No. A nightlife safety initiative designed to make drink spiking visible. In partnership with clubs and bars, Bombay Sapphire created the Glow Means No Stamp.
By integrating safety into an existing ritual, the hand stamp, Bombay is helping turn nightlife into a safer space. It’s a commitment to making sure everyone can enjoy their night out with more freedom and less fear.
How It Works
Glow Means No repurposes existing
color-reactive ink technology already used
in forensic drug tests and embeds it into
UV-reactive club stamp ink.
If your drink contains GHB, Ketamine, or Benzos, the stamp glows under club lighting when touched with a drop of the drink.
