This is a two volume set made up of Medical Toxicology of Natural Substances (978-0-471-72761-3) and Medical Toxicology of Drugs Abuse (978-0-471-72760-6) Interest and information in the field of Medical Toxicology has grown rapidly, but medical literature lacks a concise, authoritative reference work on Medical Toxicology that focuses on the four subjects of Natural Substances and Drugs of Abuse. The books provide an in-depth, sub-specialty resource on Medical Toxicology that does not compete directly with a general medical toxicology book. This approach is particularly relevant in the field of Medical Toxicology where there are many allied fields (e.g., industrial hygiene, governmental agencies, legal profession, occupational medicine, pharmacy, environmental organizations, pathology). These allied fields often do not use the majority of information in a general medical toxicology book. The style of the book allows the easy application of the contents to searchable databases and other electronic products.
