Consciousness, religion, and gurus: Pitfalls of psychedelic medicine.

Here's a good free full-text article by Matthew Johnson, professor at John Hopkins. The abstract reads: "This viewpoint identifies pitfalls in the study of psychedelic compounds, including those that pose challenges for the potential use of psychedelics as medicines. They are as follows: (1) Sloppiness regarding use of the term “consciousness”. (2) Inappropriate introduction of religious/spiritual beliefs of investigators or clinicians. (3) Clinical boundaries and other ethical challenges associated with psychedelic treatments."
