What if a blind person took some kind of hallucinogenic drug?

Anyone on hallucinogens can hear things that aren't actually there, you don't have to be blind.

That said, a large portion of a hallucination has to do with perception of experience, as much as changes to visual/auditory cues. A good portion of the 'trip' would be in how they think about things/perceive the world, rather than what they see.
