Hello, thank you for this list but I just clicked on these 2.... and the one isn't a book at all but a single page like ads.... and the second a 6 page leaflet which will falsely claim that THC doesn't cause brain damge. Well, actually it does it's due to the excito-toxicsity in the hippocampus - that's were the enormous loss of memory stems from. Any psychactive drug will change your psyche by its own plasticity. That's the price you pay for having some fun.
