Ethanol and Cannabinoid Effects on Simulated Driving and Related Cognition: Sub-Study I

Ethanol and Cannabinoid Effects on Simulated Driving and Related Cognition: Sub-Study I

The overarching goal of this study is to characterize the effects of ethanol and cannabinoids on simulated driving and related cognition.

To study the effects of oral ethanol (a target BAC of ~0.04 g/dl; equivalent to consuming approximately 2 drinks over 1 hour) and vaporized THC (4 mg of THC dissolved in an ethanolic solution; equivalent to smoking approximately 1/4 of a marijuana cigarette, or "joint") on driving.

Inclusion Criteria:

• Males or females 21 to 55 years of age (extremes included).
• Occasional current cannabis users.
• Experience with drinking 2 or more standard drinks of alcohol at least once in lifetime.
• Able to provide informed consent.
