For the fourth straight year, responding to an open-ended question, more 12- to 17-year olds named drugs the most important problem they face than named social pressures, violence, crime, or any other issue. One of a continuing series, this survey of teens, teachers, and principals is an attempt to increase understanding of the causes and effects of substance abuse. A "Foreword" (Joseph A. Califano, Jr.) highlights certain important issues and suggests approaches to solutions. Key findings are listed, and an "Overview" provides a preview of the findings of the survey. Data are discussed under the following topics: (1) "What Concerns Teens Most"; (2) "Turning 13: The End of Innocence"; (3) "It's 4 P.M. Do You Know Where Your Children Are?"; (4) "The Family That Eats and Prays Together"; (5) "Mass Media vs. Books and Homework"; (6) "Access and Attitudes: Cigarettes, Alcohol and Marijuana"; (7) "Proximity to Acid, Cocaine and Heroin"; (8) "Drug Dealing in Our Schools"; (9) "Party Time"; (10) "The Principal, Teacher, Student Disconnect"; (11) "What Is To Be Done?"; and (12) "Conclusion." Supporting data are presented in tables as appropriate to discussions. Data analysis, methodology, and data tabulations are appended. (Author/EMK)
