Not far fetched at all. Huston Smith, a very well know professor of religion was one of the people studied in the early LSD tests done on faculty at Harvard and MIT. Smith has had lots of religious experiences and not too long ago wrote a book explaining how drugs are useful in religion. (Cleansing the windows of Perception??)
My wife is currently writing a paper on the physiological basis of religious experience. There's a psychologist named Persinger at Laurentian University in Sudbury Ontario that has designed an electromagnetic helmet which when activated on the head, causes a person to experience God. Very interesting stuff.
