“Monitoring the Future is an annual survey of 8th, 10th, and 12th-graders conducted by researchers at the University of Michigan, Ann Arbor, under a grant from the National Institute on Drug Abuse, part of the National Institutes of Health. Since 1975, the survey has measured drug, alcohol, and cigarette use and related attitudes in 12th-graders nationwide. Eighth and 10th graders were added to the survey in 1991. Overall, 41,675 students from 389 public and private schools participated in the 2013 survey.”
