Do blind people hallucinate on LSD?

I’ve just found a remarkable 1963 study [pdf] from the Archives of Opthalmology in which 24 blind participants took LSD to see if they could experience visual hallucinations.

It turns out, they can, although this seems largely to be the case in blind people who had several years of sight to begin with, but who later lost their vision.

Those blind from a very early age (younger than two years-old) did not report visual hallucinations, probably because they never had enough visual experience to shape a fully-functioning visual system when their brain was still developing.

  1. The hallucinations I experienced (not being blind) were Synesthesia; Stroboscopic spatial distortions; Time dilation; depersonalization; feeling as though walking under water. Visual hallucinations with eyes open were not seen. Other experiences were strong sense of mental telepathy and increased energy. A blind person in my opinion could have visions and experience synesthesia- for example his/her body can be a symphony of sound.
