Summary

This study tests a CE-marked mobile app that scans a person's eyes to detect whether they have used certain drugs. Healthy volunteers will take a common medicine that mimics the effects of cannabis or amphetamines, then use the app to see if the eye measurements change. The goal is to improve the app's ability to monitor drug use in people being treated for substance use disorder.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a mobile phone application (Previct Drugs) that performs eye-scanning to measure pupil and eye parameters
What this could lead to
If successful, this could provide a non-invasive, remote way to monitor drug use in people undergoing treatment for substance use disorder.
What could go wrong
This is a small, early-stage study in healthy volunteers using simulated drug intake, so results may not translate directly to real-world patients or all substances.
