Query: Good not great

The author is strongly against the War on Drugs and he tries to provide as neutral as possible a look at the facts. He is certainly not anti-recreational drugs which I found to be a nice change. It has a good history of drugs and their effects but it could have had more practical information e.g. I wanted to know how much marijuana to use for oral consumption as compared to how much I smoke and this book was of no help.Overall good beginners summary of history and effects of common recreational drugs. Good not great
