The placebo condition consisted of orange juice with ~3 ml of vodka floated on top for masking.Breathalyser readings were taken using a Lion Alcolmeter SD400PA that was calibrated quarterly by the Road Policing Division, Victoria Police. Approximation of BAC was determined though breath alcohol content at 20 min, 1 h and 3 h after treatment.
