8 It has been conducted annually by the University of Michigan s Institute for Social Research since its inception in 1975 and is supported under a series of investigator-initiated, competing research grants from the national Institute on Drug Abuse. The need for a study such as MTF is clear. Substance use by American young people has proven to be a rapidly changing phenomenon, requiring frequent assessments and reassessments. Since the mid-1960s, when it burgeoned in the general youth population, illicit drug use has remained a major concern for the nation.

9 Smoking, drinking, and illicit drug use are leading causes of morbidity and mortality, during adolescence as well as later in life. How vigorously the nation responds to teenage substance use, how accurately it identifies the emerging substance abuse problems, and how well it comes to understand the effectiveness of policy and intervention efforts largely depend on the ongoing collection of valid and reliable data. MONITORING the Future is uniquely designed to generate such data in order to provide an accurate picture of what is happening in this domain and why, and the study has served that function well for the past 39 years.

10 Policy discussions in the media, in government, education, public health institutions, and elsewhere have been informed by the ready availability of extensive and consistently accurate information from the study relating to a large number of substances. Similarly, the work of organizations and agencies providing prevention and treatment services is informed by MTF. The 2013 MTF survey encompassed about 41,700 8th-, 10th-, and 12th-grade students in 389 secondary schools nationwide.
