I am a narcotics prosecutor in the US who deals with this problem on a daily basis. I have friends who have ruined their lives and others who seem to funtion to a point. This book is the real deal and should be read by anyone concerned with or just wants to educate themselves. If someone you care about has this problem, the book will not help you help them. It will give you an idea of what you are up against. There is always hope and education is a powerful tool. I purchased copies of this book and distributed it to my entire narcotics unit with the hope that compassion will coincide with enforcement.
