NCT ID NCT07401628

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study aims to see if sensors inside a car can tell when a driver is impaired by cannabis. Forty-five healthy adults who regularly use cannabis will drive on a closed track after smoking a controlled dose of THC. Their driving behavior, eye movements, and other data will be compared to sober driving to train a computer model to detect impairment.

What this could mean

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

Active substance

Cannabis (THC)

What this could lead to

If successful, this could lead to a real-time in-vehicle system that alerts drivers when they are too impaired to drive safely after cannabis use.

What could go wrong

This is a small, early-stage study with only 45 participants on a closed track, so results may not apply to real-world driving or all cannabis users.
