Designed for the introduction to drugs and substance abuse course as taught in departments of health education, psychology, biology, sociology, and criminal justice, this full-color market-leading text provides the latest information on drugs and their effects on society and human behavior. For over thirty years, instructors and students have relied on it to examine drugs and behavior from the behavioral, pharmacological, historical, social, legal, and clinical perspectives.New co-author Carl Hart--an active researcher currently conducting laboratory research on marijuana, methamphetamine, and MDMA--brings to the book his research experience as well as his experience in teaching the drugs course. Chapters have been reorganized for better content flow. The book now opens with historical information, moves to a discussion of the ways in which drugs affect the body, offers information about individual drugs, and closes with prevention and treatment. A list of "Chapter Objectives" now opens each chapter, alerting students to key concepts they'll need to learn and providing a convenient outline for study or review. Online Learning Center and PowerWeb topics are now integrated into chapter discussion. At key points throughout the text, specific topics and features of the Online Learning Center are highlighted, providing the student with greater opportunity for further reading, discussion, and activities.Approaching drugs and drug use from a variety of perspectives (behavioral, neuropharmacological, historical, social, legal, and clinical), the book appeals to a wide range of students. "Targeting Prevention" boxes throughout offer in-depth discussion of issues related to treatment and prevention. "Check Yourself!" activities conclude each section, helping students apply the material learned. "Drugs in Depth," "Taking Sides," "Mind / Body Connection," and "Drugs in the Media" boxes invite students to explore in depth controversial and timely topics.
