This report discusses results of the 1998 Texas School Survey of Substance Abuse among Students. Results for secondary students were based on responses of 158,324 students in 66 school districts. This book is divided into six chapters. Chapter 1 discusses the findings of the survey on a drug-by-drug basis to provide information on trends in the use of each substance and the characteristics of those students who reported using each substance. Chapter 2 examines this same information in terms of the relationship of substance use to demographic characteristics. Chapter 3 looks at protective or resiliency factors that can help students resist substance use despite the presence of risks for use. The negative consequences experienced due to substance abuse are examined in chapter 4. Chapter 5 discusses sources of assistance and information concerning substance abuse, including substance abuse education. The final chapter offers conclusions drawn from the survey. Appendixes provide a copy of the survey instrument, charts and tables depicting results of the survey, a description of the survey, and limitations of the study. (MKA)
