Experimental
Placebo Comparator
No Intervention
Alcohol condition
Placebo condition
Control (water)
The amount of alcohol received in the alcohol condition will be determined by an algorithm developed by Curtin (Curtin, 2000). Participants in the alcohol condition will receive a dose of alcohol (target BAC = .08%), administered in a chilled beverage of 80-proof vodka mixed with tonic water and lime juice in a 1:4 ratio.
Placebo participants will receive tonic water and lime juice served to enhance alcohol cues in an amount comparable to the amount that they would have received if assigned to the alcohol condition.
Participants in the water control condition will receive a glass of chilled water in volume of liquid comparable to the amount that they would have received if assigned to the alcohol or placebo condition.
