Holy Quadruplity sounds like the Heidegger concept, the quadrant divinity, amazing concept...
to be honest I've never taken a deliriant but the more I think about it the more "interesting" it seems, even knowing that most of them are very very dangerous, even as serious as to cause death if one it's not lucky/very aware of how they need to be used.
I would never try with the worst ones, but there's some interesting stuff that has tropane alkaloids in a way that makes them "deliriant enough" but not "deliriant enough to kill you" at least at normal doses,
I'm investigating those plants, since a couple months ago, most of them belong to the famous family Solanaceae, some are very similar to Physalis Peruviana or Ashwagandha (that are in that family).
Nicandra Physalodes it's an interesting one that I would like to study carefully. Probably there's others, specially some included in the Traditional Chinese Medicine.
There's some old plants, not very used today, that were associated with European Witchcraft, Belladona, Hyoscyamus Niger, Mandragora Officinarum (Mandrake), Jimsonweed...
all of them have a place in traditional medicine, but all of them are pretty dangerous. I use JImsonweed seeds (2-6) to potentiate psychedelics or if I have motion sickness.
