The editing of this book was not done overly well - there are several times where the jumps in thought seem completely random, as well as sentences that were written with two thoughts in mind and never connected.
It's also an outdated book in terms of information provided, I could never tell from what perspective the authors were writing. They are obviously in favor of allowing the use of peyote - but how they view the people who do so, I could not tell.
It's a book that leaves me confused on what useful information I gleaned from it - what sources can I trust and did I learn anything to try to trust in the first place.
I am sure the authors did their best, but I wouldn't recommend this as a read for any purposes I can think of at the moment.
