Study Overview
Brief Summary
The overarching goal of this study is to characterize the effects of ethanol and cannabinoids on simulated driving and related cognition.
Detailed Description
To study the effects of ethanol clamped at BAC 0.04% (equivalent to consuming approximately 2 drinks over 1 hour) and oral Dronabinol (10 mg capsule) on driving.
