Does this mean that, if blind people take some drug that has an effect on the "visual areas", their math gets screwed up? What if you gave them a - for sighted people - highly visual psychedelic, will their algebra be all weird (or, weird in a different way than it would be for a sighted person)?

That's an interesting question. I don't know an answer, but I did find this post about an old experiment: https://mindhacks.com/2009/11/18/do-blind-people-hallucinate...

It's very unlikely that anything similar would be done today.
