Reliability of Drug-Detecting Bracelets: A Review of Effectiveness
The recent introduction of bracelets that use color tests to detect the presence of drugs in drinks has sparked interest in their potential to prevent “spiking” – the intentional addition of substances to impair a person’s cognitive or physical abilities. However, a study by the National Center for Addiction and Doping of the Istituto Superiore di Sanità has found that these devices are currently “unreliable and could be improved”. The research highlights that while the bracelets work quite well for detecting ketamine, they are ineffective for other substances.
Methodology and Findings
Researchers from the National Addiction and Doping Center tested two different types of devices on the market, evaluating their reliability in detecting GHB, ketamine, scopolamine, cocaine, MDMA, and benzodiazepines. The study used combinations of common alcoholic cocktails, including white wine, sparkling wine, gin, and a bitter and colored alcoholic cocktail, and spiked them with concentrations typical of recreational use. The results showed that the color change indicating a positive reaction was clear for ketamine, but poorly defined for GHB and other substances.
The study also found that the color of the drink itself can affect the precision of the detection, with red cocktails and lemon or orange drinks causing false positives. Furthermore, the rapid test needed to be repeated several times for some substances, such as cocaine. According to Simona Pichini, director of the National Center for Addiction and Doping of the ISS, “the colors are precisely one of the critical points of these devices… under a reduced and changing light such as that of discos, the change from one color to another may not be perceived and therefore be unmistakable, as a symbol would be”.
Conclusion and Recommendations
The study’s findings suggest that while the idea of wearable devices that can detect drugs in drinks is promising, the current technology has limitations. To improve their effectiveness, the researchers recommend replacing the color-based system with a symbol-based system, which would be more easily perceivable in low-light conditions. Additionally, the devices need to be more sensitive and reliable in detecting a range of substances. As the issue of “spiking” continues to be a concern, it is essential to develop and refine technologies that can help prevent and detect such incidents.
