http://www.monitoringthefuture.org/

Monitoring the Future is an ongoing study of the behaviors, attitudes, and values of American secondary school students, college students, and young adults. Each year, a total of approximately 50,000 8th, 10th and 12th grade students are surveyed (12th graders since 1975, and 8th and 10th graders since 1991). In addition, annual follow-up questionnaires are mailed to a sample of each graduating class for a number of years after their initial participation. The Monitoring the Future Study has been funded under a series of investigator-initiated competing research grants from theNational Institute on Drug Abuse, a part of the National Institutes of Health. MTF is conducted at the 
Survey Research Center in theInstitute for Social Research at theUniversity of Michigan.
