Instruct: Classify Amazon reviews into positive or negative sentiment
Query: This is information that everyone should know

I heard Dr. Pinsky on loveline talking about some of the negative reviews that he had been getting here on Amazon for his book, and I must say, I read this book and it contains not only information on the process of addiction and recovery, but some very profound insight into society as a whole and how different drug and alcohol factors will affect many people.This is a must read if you know someone with drug or alcohol related issues.Dr. Pinsky, this book is awesome. Don't let negative reviews on your book here get you down, they're just ignorent and probably too wasted to understand the meaning of your book anyways. Cracked gets 5 stars from me.
