Summary

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

Detailed description

Conditions

• Cannabis
• Alcohol Effect
• Driving Under the Influence of Alcohol and Other Drugs

Interventions

Type	Name	Description
DRUG	Active delta-9-THC	Low dose (0.015 mg/kg = 1.05 mg in a 70 kg individual) THC, dissolved in alcohol. This dose is roughly equivalent to smoking approximately 1/4 of a marijuana cigarette, or "joint". Administered over 20 minutes.
DRUG	Placebo	Control: small amount of alcohol (quarter teaspoon), with no THC. Administered over 20 minutes.
DRUG	Active Ethanol	Target BrAC of 0.04% reached over 20 minutes and then clamped to maintain this dose for an additional 60 minutes. This dose is equivalent to consuming approximately 2 drinks over 1 hour. Administered over a total of 80 minutes.
DRUG	Placebo	Control: no alcohol, administered for a total of 80 minutes.
