Glass condom, anti-GHB/Ketamine bracelets and cards: uses and limitations
Protecting the glass or testing the drink: two complementary approaches
The glass cover acts as a physical barrier. Colorimetric bracelets and cards detect certain substances specified in their instructions. These tools can enhance prevention, but none make a drink or event completely safe.
The glass cover: preventing discreet introduction
The glass cover covers the container’s opening while allowing a straw to pass through. Its main benefit is preventive: it complicates adding a substance when the glass is being held or set down. It does not allow knowing if a drink was already contaminated before being placed.
Bracelets and cards: detect certain substances
Test Ton Verre® supports rely on a colorimetric reaction. A small amount of drink is placed on the designated area, then the result is compared to the instructions. They are designed to detect GHB and ketamine under the indicated usage conditions.
Which tool to choose?
Glass cover
Designed to physically protect the glass during an event. It is useful before any suspicion arises but does not perform detection.
Test Ton Verre® Bracelet
Easy to distribute and carry. It can be customized from 500 units for professional and event campaigns.
Test Ton Verre® Card
Non-customizable, it easily slips into a wallet or phone case. It is suitable for discreet availability.
Combined approach
Physical protection, targeted detection, team training, and an emergency protocol provide a more coherent response than a single tool.
How to use a drink test responsibly?
- Read the instructions before the event and respect the indicated drink volume.
- Check the expiration date and storage conditions.
- Interpret the reaction under sufficient lighting and within the specified time.
- Never consume a suspicious drink, even after a negative result.
- In case of discomfort, do not wait for a test result to seek help.
What to do in case of doubt?
Remove the person from the dangerous situation, do not leave them alone, and contact emergency services if their condition requires it. Keep the glass if it can be done without delaying care. Medical and toxicological samples must be taken quickly by qualified professionals.
