What would someone who is blind experience when under the effects of LSD?
Ah, and it summarises a study within this report – http://www.erowid.org/psychoactives/journals/psychoactives_journal3.shtml “Because hallucinations and illusions were reported only when ERG and dark adaptation changes occurred, a possible primary retinal role has been considered in the etiology of LSD hallucinations. To test this, Krill, et al. (25), did a double-blind controlled test with 24 blind subjects. Thirteen of 24 subjects including some with bilateral enucleations reported visual hallucinations with LSD, making it evident that a normal retina is not needed for visual hallucinations to be produced by hallucinogenic drugs. The ERG in 2 blind subjects with total optic atrophy was similar to those seen in normals with LSD but these blind subjects did not have hallucinations. Hallucinations occurred in blind subjects reporting prior spontaneous visual activity. (Two previous uncontrolled studies(27,28) had reported visual hallucinations in blind subjects on hallucinogenic drugs w
interesting question… as others have noted, it would depend upon the individual’s condition & history – for instance, folks who have suffered some form of optic degeneration can be prone to hallucinations (see Charles Bonnet Syndrome) – however, someone who has been blind since birth is a different story one possible path to this answer might be to look into what what a blind person experiences when they dream… check out this study:
