Summary

This study tests whether codeine can be detected in fingerprint sweat as accurately as in oral fluid. Forty healthy adults will receive two doses of codeine, and researchers will compare the results from both sample types. The goal is to find the best cutoff level for fingerprint sweat to match oral fluid testing, potentially enabling a less invasive drug screening method.

What this could mean

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

Active substance: codeine phosphate tablets
What this could lead to: If successful, this could lead to a non-invasive fingerprint sweat test for opiate screening, offering a quicker and easier alternative to oral fluid testing.
What could go wrong: This is a small, early-stage study in healthy volunteers, so results may not apply to real-world drug testing. The fingerprint method is experimental and may not match oral fluid accuracy.
