I think it can be easy to jump to the conclusion that because Bill was given a hallucinogen in his hospital stay that this "caused" his spiritual experience. But it's important to understand the distinction between a “hallucinogenic” and "psychedelic" drug. There are
three forms of hallucinogenic drugs.
1) Dissociatives "produce a feeling of being unreal or totally disconnected from oneself, or a kind of derealization in which the outside world seems completely unreal".
2) Psychedelics, like LSD "can produce "the warping and distorting of shapes and surfaces, and strange alterations incolor. Some people see repetitive geometric shapes. Some people may experience what they believe to be higher spatial/temporal dimensions" People who take psychedelics claim on some occasions that the drug put them in contact with God, the Infinite, or some other kind of divine realm".
3) Deliriants, like belladona are not at all like psychedelics; they produce a state of delirium in which drug takers fall into a stupor, or a state of complete mental confusion.
Bills white light spiritual experience in the hospital is not consistent with with belladona, which is
not a psychedelic.
