Overall, this an excellent compendium of 11 classes of compounds that have the potential to lead to a substance abuse disorder. The handbook corresponds to the substance abuse disorders listed in DSM-IV in 1994. The book is divided into 12 sections, each organized into chapters on pharmacology, behavioral pharmacology, and the psychological and psychiatric consequences of each particular compound or psychotropic medication. As a small point, the multiauthored book (there are 62 authors) lists its contributors without a professional degree. Therefore, the reader is unaware initially as to whether the writer is a physician, a pharmacologist, or both. It is unclear why the various authors, many of them very knowledgeable, are not listed with their professional degrees.
