Or they took something that was presented as LSD but was actually something else. This sounds like the kind of nerve damage people get from taking dangerous doses of MDMA. Not saying it's MDMA specifically but it could have been something neurotoxic.

Their experience sounded nothing like MDMA. And some small group of "lucky" people do have similar after-effects from LSD or even mushrooms (see https://en.wikipedia.org/wiki/Hallucinogen_persisting_percep... ).

I have no reason to think it wasn't LSD, but there's also a decent possibility it was something else passed off as LSD, which is a fun consequence of the war on drugs.
