Query: Don't waste your money - it doesn't even deserve one star!

I was sorely disappointed with this book. There are not enough pictures and diagrams. The ones that are included are poor quality. The material is old and seams to be a compilation of research by a Vietnam era hippie more than an authoritative volume. There is an entire chapter on drugs (from the 60's it appears)... what a waste of space and time. If I wanted to learn about illegal drugs I would have bought "The Drugmaker Cookbook" or some other such title! To top it off - it was not even an interesting or entertaining read!
