New study tests High-Tech car sensors to spot stoned drivers
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.
