If you haven't read it already, you should totally read "How to Change Your Mind" by Michael Pollan. The book more or less agrees with your point (though I don't think the science has necessarily come to a solid conclusion on which mental disorders psychedelics are going to help relieve. I think alcoholism had a fairly high response rate, though). I believe the book "Capture" by David Kessler also covers the phenomena of how minds can end up "stuck" in some mode, so to speak, though I have yet to read that one.
