This book is in itself a good guide to holding an intervention, however I disagree with the information that is used to support it. Throughout the book there are claims that it is a disease, much like diabetes or mumps, and that any time spent looking for enviormental causes, or any cause other than biological, is in fact a waste of time and is detrimental to the addicts chances of recovery.
I find this very closed minded, based on the simple fact that it has only been classified as a "disease" in order to proctect those who are addicts so they will not lose thier jobs, insurance coverage, and will be able to recieve help from society. There is no scientific evidence to prove the theory that addiction is a biological cause, meaning that no outside influences can affect it. If someone has diabetes, a stressful home life does not make them produce more or less insulin, however it can cause an alcholic to want to drink.
I would not recomend this book as anything but a step-by-step intervention guide.
