"Psychedelic Spirituality" is an attempt to synthesize, in one work, both the academic and spiritual, the anecdotal and the collective. Ruminating on dozens of mind altering substances, their spiritual use as entheogens, the drug war, and more, it derives from the ancient and modern and seeks to enlighten the reader. This second edition has been somewhat reworked, improving the format and changing a bit of material now outdated since its first release in 2015. Altogether, it is calculated to give the reader a broad and general overview of dozens of psychedelic sub-topics.
