Query: Horrible Book

The newest edition still has information that was out of date when the book was originally published. It seems like these authors updated only the bare minimum, the stats and laws.This book is called substance abuse, and in the first chapter and a half goes on to define everything except "abuse." If they did define "abuse" then they could not get away with the things they were writting, some would be misleading and some would be wrong.They clearly have an agenda of thie own in writting the book, their own opinions, and not an object view.Thomas Harrison, Ph. D. in his 2007 class used the last version of his text, but also needed to recommend 4 other books to his students to get the points accross. While I applaud him for not assuming he knows it all, this book is truly not a good tool for a generalist trying to practice.
