I was going to suggest this same book, it was very informative from what I can remember.sinenomine said:I highly reccomend "The Emperor Wears No Clothes", by the famous Jack Herer. There's some absolutely fascinating stuff about weed's history and culture.
For example, did you know that during alcohol prohibition in the 20s, there were more hashish parlors in New York City than there were alcohol speakeasies?
TA large portion of the book is available online, its real long but way worth it to read all the way through.
