Summary

This study looks at how different doses of THC (the active ingredient in cannabis) affect eye movements and attention. Researchers will test 40 adults—some who use cannabis often and some who use it rarely—to see if eye-tracking can reliably detect impairment. The goal is to develop a better way to identify when someone is too impaired to drive safely.
