This is a drug residue test for Benzodiazepines. It is called a colorimetric assay that detects and identifies Benzodiazepines, often called ‘Benzos.’ This simple on contact test contains two analysis papers suitable for two to four independent trials. By wiping the analysis paper on a suspect article or surface and adding a drop of liquid from the ampoule, the results appear as a color change.

With the widespread abuse of Benzodiazepine based drugs, it is now possible to detect and identify these harmful and addictive drugs very quickly. Once discovered, you could make an informed decision on how to proceed, either by talking to the suspect individual or informing the authorities of your findings.
