From the President of the American Society of Addiction Medicine Recent Developments in Alcoholism (Volume 10) is a major contribution to the literature of addiction medicine. This volume, 'ru.cohol and Cocaine: Similarities and Differences," contains an impressive collection of chapters from the basic research, epidemiological, and clinical research perspectives, as well as articles that address the relative policy issues and clinical application and patient care concerns. It also sends a message to those who would still distinguish between alcohol and drugs, or legal and illegal drugs. In the research laboratory, in the intentions and behavior of the user, and by the clinician, such distinctions have never been upheld. The first section, "Clinical Pathology," includes chapters on the role of alcohol in cocaine dependence, dual-diagnosis empirical and developmental­ humanistic approaches, and on neuroendocrine and catecholamine levels in humans during administration and withdrawal of cocaine and alcohol, emer­ gency room evaluation of cocaine-associated neuropsychiatric disorders, and clinical and pharmacological interactions of alcohol and cocaine. These chap­ ters, written by authors who are preeminent in their fields, offer a broad perspective to both the researcher and the clinician on relevant issues in clinical pathology. .
