The Science Behind Spike Shields
Learn how Spike Shields stickers work, what they detect and how we validate their performance to support real-world drink safety.
SCIENCE
How Spike Shields detects drink spiking drugs
Spike Shields uses colorimetric testing, a technique where chemical reagents produce a visible color change upon interacting with specific target compounds. Applying a small drink sample to the test pads causes the reagents to react selectively, generating a color response within seconds.
This rapid, reaction-based method allows for reliable, on-the-spot screening without instruments or equipment in real-world social settings.
Substances Spike Shields can detect
Spike Shields screens for a broad range of commonly used drink spiking drugs. Current detection includes:
- GHB
- Ketamine
- Benzodiazepines
- Morphine
- Etomidate
- Triazolam
- Opium
Our detection categories continue to expand as our chemistry and validation methods evolve. Updates are published as new capabilities are confirmed.
What drinks can be tested
Spike Shields stickers are validated on the most commonly consumed beverages including beer, wine, cocktails, spirits, sodas and juices. The color or thickness of these drinks does not interfere with the reaction.
Certain opaque liquids such as milk or coconut milk are still under evaluation. Compatibility updates will be shared as testing progresses.
How we validate performance
Spike Shields is engineered and rigorously evaluated in controlled laboratory settings to deliver dependable results. Independent validation is performed by accredited third-party toxicology laboratories affiliated with leading North American universities and hospitals.
Testing includes:
- Reaction testing across different concentrations of each substance
- Cross testing on various beverage types
- Shelf-life and stability validation
- Continuous refinement based on partner and community feedback
Spike Shields is a screening tool designed for fast, visual detection to support safer decision making in social settings.
Important information to know
While Spike Shields detects a wide range of substances, no test can identify every possible drug. A clear result should not override personal judgment. If something feels wrong, users should not consume the drink.
Spike Shields is a harm reduction tool, not a lab-based diagnostic device. Results are visual indicators and should be used alongside broader safety awareness.
