The proposed study will validate and determine sensitivity of our new driving simulator, created to evaluate driving ability in a related study to show similar driving performance between patients on chronic opioid treatment and a control group. Although the commercial version of the simulator has been validated for certain populations and certain measures, these require re-calibration for our own clinical study. The investigators propose a prospective randomized clinical trial to evaluate driving skills under alcohol consumption using a driving simulator. Two groups of study subjects will be utilized, with the majority (80%) receiving alcohol and placebo at different times. A smaller set of study subjects (20%) will be given placebo on both trials to evaluate learning effects and placebo blinding effectiveness. Each group will take the driving test at three time points: once as a baseline at the beginning of the study, once after the 1st dosing of the placebo and again after dosing two of the alcohol or placebo beverage. This information will allow us to evaluate driving ability under other potentially impairing conditions such as opioid usage.
