From the 2009 Monitoring the Future Survey:
Think back over the LAST TWO WEEKS. How many times have you had five or more drinks in a row? (A "drink" is a glass of wine, a bottle of beer, a wine cooler, a shot glass of liquor, or a mixed drink.)
Data are based on students in attendance on the day of the survey administration. A description of MTF was published by NIDA.
