A negative result from the nail sticker cannot establish that a drink is safe: the device is a preliminary screen designed specifically for GHB and does not detect every drug. Agencia EFE reported that Valencian company Grupo Lizne has agreed exclusive distribution in Spain with South Korean laboratory Philmedi.
Sold under the name ‘Spy nails by Freshia’, the decorative stickers come in ten designs, including hearts and stars, plus crosses and skulls, and have a discreet reactive area. The sticker is intended to change from yellow to green when it detects GHB, described in the report as liquid ecstasy. The stickers are intended to be sold in packs of ten tests. The product is not a substitute for laboratory analysis.
Jorge Lizondo García, a Grupo Lizne partner, said the project grew out of concern about drug-facilitated sexual assault and prevention. He cited the La Manada case during the Sanfermines in 2016 as a lasting influence. The company has said it was seeking sales agreements with pharmacies and perfumeries, as well as festival organisers. “Puntos Violeta” and online sales were also among its proposed channels.
At the time of EFE’s report, a laboratory at the Universidad de Valladolid had certified the product as a generic product and manufacturing was under way. Grupo Lizne planned to begin presales at the end of November 2026 and set a target of distributing more than 500,000 units during the first 12 months; the price was described as intended to be as affordable as possible. That certification does not change the stated limits of the test: GHB is one of several substances that may be added to drinks without a person’s knowledge or consent, alongside alcohol and ketamine, with benzodiazepines also among them. The company advises anyone who suspects a drink has been tampered with not to consume it and to contact emergency services if necessary. The distinction between preliminary indications and firm conclusions also appears in a reported field trial, though that study concerned a different subject.
