This is a famous case from the 70s: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1129381/?page=1

Summary: 8 people at a party in SF “accidentally” (having mistook it for cocaine, as one does) snorted at least two lines each of powdered LSD. Somehow, they made it to the hospital 10 minutes later. 5 of them were in a coma by the time they were seen, and 3 had to be intubated. One person had a temperature of 107F + 200BPM pulse. One of the comatose patients discharged himself after 12 hours, and they all seemingly recovered fully. But without prompt medical care…probably not.

Conclusion: Do not snort a 1000x dose of LSD.

I read the paper and I think there's another explanation. They say the seized material was "almost pure" LSD- 80 - 90%. But "almost pure" LSD is 99.9% or more. Seems more likely the material was contaminated with something else that caused the reaction.
