"There is an increasing disconnect between public attitudes and published science on marijuana. Given the current level of discourse and the importance of this issue to the health and wellbeing of many Americans, it is critical that we have objective, fact based information with which to guide our laws and policies. This edited volume takes us a long way towards that goal, and should be required reading for anyone seeking facts on marijuana." -- Micha el Botticelli, Executive Director, Grayken Center for Addiction Medicine

"The legalization of marijuana brings strong opinions, on both sides. This book focuses on the science of marijuana. With chapters by leading experts across a range of fields from epidemiology to treatment and criminal justice, it sheds light on a contemporary debate." -- Nancy Petry, PhD, Professor of Medicine, University of Connecticut School of Medicine

"Drs. Sabet and Winters have convened a stellar group of contributors for Contemporary Health Issues on Marijuana. These scholars have cast a broad net to offer readers a timely and sensible analysis of marijuana use and its consequences. Individual chapters focus on a panoply of issues central to advancing our understanding of marijuana use. The chapters cover a wide range of topics, from the epidemiology of marijuana use patterns, medicinal marijuana use, and the health consequences of marijuana use, to treatments for marijuana use, a thoughtful consideration of driving under the influence, and the public policy implications of marijuana use.

Each chapter in this volume is sharp, focused and clearly written. Perhaps most importantly, this volume represents thoughtful contributors who offer a fair and balanced assessment of the state of marijuana use-without prejudice. This is a must read for any clinician, scientist, public health worker, or public policy maker." -- Howard J. Shaffer, PhD, C.A.S., Morris E. Chafetz Associate Professor of Psychiatry in the Field of Behavioral Sciences, Harvard Medical School & Director, Division on Addiction, The Cambridge Health Alliance
