In addition, trends in the perceived American adolescents, college students, and adult high availability of each drug are presented, which at times school graduates through age 55. It has been conducted have proven important to explaining changes in usage annually by the University of Michigan’s Institute for levels for some drugs. Social Research since its inception in 1975 and is supported under a series of investigator-initiated, A synopsis of the design and methods used in the study competitive research grants from the National Institute and an overview of the key results from the 2015 on Drug Abuse. survey follow this introductory section. These are in turn followed by a separate section for each individual The need for a study such as MTF is clear. Substance drug class, providing figures that show trends in the use by American young people has proven to be a overall proportions of students at each grade level (a) rapidly changing phenomenon, requiring frequent using the drug, (b) seeing a “great risk” associated with assessments and reassessments.
