There were multiple, I think they were called 1p-LSD, 1cp-LSD, 1d-LSD, 1v-LSD and currently you can still legally buy 1S-LSD. Its a bit of whack-a-mole with the lawmakers because there isnt a blanket ban, only ever the specific chemical gets banned. Although stuff got quite a lot more expensive with every iteration.
