To minimize risk, the following procedures outlined in the NIAAA Recommended Council Guidelines on Ethyl Alcohol Administration in Human Experimentation were used (NIAAA, 2005). Participants were not allowed to leave the laboratory until their observable behavior had returned to normal and until their BrAC fell below 0.02mg%. Each participant was also required to travel home by taxi (provided by the study), or with a friend. Participants were required to state in writing that he or she would not drive a car or operate other machinery for three hours after leaving the laboratory. They were reimbursed $100 for participation in the session.
