Using Imaging to Assess Effects of THC on Brain Activity

Dronabinol at physician determined doses of 10-80mg designed to produce intoxication.

Oral Ethanol, dosed to obtain a breath alcohol concentration (BrAC) of approximately 0.05 BrAC (equal to 1-2 standard drinks).

Identical in appearance to active dronabinol (overencapsulation of both active and placebo dronabinol)

Placebo ethanol will consist of diet soda used in the active ethanol condition with 0.25ml ethanol floated on top to provide the odor of ethanol and blind the study drug.
