Forensic Toxicology [PDF ebook] 
Mechanisms and Pathology

Designed for graduate and advanced undergraduate courses, this book goes beyond the simple analysis of naming a drug or toxin, taking a mechanistic approach to their effects on the body. It provides an understanding of the mechanisms of action of drugs and toxins as well as their physiologic and pathologic consequences on the affected organ system. Case histories, photographs of gross pathology, and photomicrographs further illustrate the processes and effects of toxic substances on the body.
