B-SAFE: French drink drug detection innovation
B-SAFE: a new generation of drink detection
B-SAFE is a connected electronic detector developed by LUEUR and officially distributed by AMA Prévention. It helps professionals quickly analyze a suspicious drink, obtain an indication via a mobile interface, and promptly trigger a safety protocol.
An electronic, connected, and reusable device
B-SAFE is not limited to a color change on a single-use medium. The device combines a miniaturized sensor, electronic reading, and a mobile interface that provides more details on the obtained indication.
This architecture is designed for bars, clubs, festivals, BDE, communities, ERP, security teams, first aid posts, and prevention actors who must manage suspicion in a real environment: low light, high public flow, and the need to act quickly.
What truly sets B-SAFE apart
Electronic reading
The result is not based solely on a visual assessment. The device provides an indication designed to facilitate the team’s response.
Mobile application
Connection to the mobile interface allows for refined reading and access to detailed information on the type or family of detected substance.
Evolving technology
Service and device updates allow the available information to evolve and, depending on the manufacturer’s validations, the covered spectrum.
French ecosystem
Development and manufacturing in France, with support, technical assistance, and after-sales service based in France.
Seven patent filings to protect the technology
LUEUR’s documentation highlights 7 patents filed with the INPI. This industrial property strategy reflects the extensive research work carried out around the sensor, miniaturization, analysis, and the connected ecosystem.
A patent application protects an invention or a family of innovations; it does not, by itself, replace performance tests or the usage conditions provided by the manufacturer.
Professor Jean-Claude Alvarez associated with scientific development
In the project documentation, LUEUR indicates that B-SAFE benefits from the support of Professor Jean-Claude Alvarez, professor of pharmacology-toxicology and recognized specialist in analytical and forensic toxicology in Garches.
This expertise helps scientifically frame the development and interpretation of performance. However, B-SAFE remains a prevention and decision-support tool: it does not replace a medical diagnosis, official toxicological analysis, or forensic evidence.
How does B-SAFE work?
Sample
Dip the designated tip into the suspected drink according to the manufacturer's protocol.
Analyze
The device takes its measurement and provides a first indication within seconds.
Interpret
The mobile interface complements the reading with available detection information.
Protect
Isolate the drink, secure the person, and immediately apply the establishment's protocol.
A multi-substance approach, not just anti-GHB
Chemical submission can involve various sedative, medicinal, or psychoactive substances. B-SAFE is presented as a broad-spectrum detector, with more than 30 substances or families targeted depending on the version and manufacturer data.
A tool designed to structure team response
Bars and clubs
Create an identified checkpoint and train a reference team.
Festivals and events
Equip prevention, security, or first aid posts.
BDE and associations
Strengthen student parties with a written and visible procedure.
Local authorities and public venues
Integrate B-SAFE into a broader public protection policy.
The test never replaces securing the person
- Do not leave the person alone and move them away from danger.
- Stop consumption and keep the drink if it can be done safely.
- Immediately notify management, security, or first aid station.
- Call 15 or 112 in case of drowsiness, confusion, loss of consciousness, or breathing difficulty.
Key answers
Does B-SAFE detect only GHB?
No. B-SAFE is presented as a multi-substance solution covering more than 30 substances or families according to the documentation and system version.
Why is the mobile application important?
The device provides a quick indication. The mobile interface offers an additional reading level on available information regarding the type or family of detected substance.
What do the seven patents represent?
LUEUR states it has filed seven patents with the INPI around the technology. They protect innovative elements; they do not replace testing and device usage limits.
Does B-SAFE replace laboratory analysis?
No. B-SAFE is a prevention and decision-support tool. Only samples and analyses performed in a medical or medico-legal context can provide official confirmation.
Who is B-SAFE for?
Mainly for professionals and organizers: bars, clubs, festivals, BDE, local authorities, public venues, security teams, and prevention actors.
Integrate B-SAFE into a professional protocol
AMA Prévention, official distributor of LUEUR, supports organizations in handling, deployment, team awareness, updates, and assistance.
