Known for clarity, accessibility, and practicality, this widely-used book thoroughly examines substance abuse in the population, addressing both ways to measure the problem and how to treat individuals and families who seek assistance. It educates prospective clinicians and counselors by guiding them, step-by-step, through the process of working with substance-abuse clients. Chapter content builds in sequence; however, each chapter can be taken as a stand-alone source of valuable information. Individual chapters on special populations add substantial depth to the text's treatment of its subject.
