Well, I enjoyed his little book and yes, there are 4 sections, but you will note a disproportionately larger section on marijuana than the other plants/fruits. He seems taken with it, due to some recent positive experiences of his while smoking it; OK, but the tone of the book up to that point was supposed to be objective. That chapter, IMHO fell down, because it got too subjective, and I got the distinct impression he was a bit of a pot head.
