SWIM has the black seeds.

10 Datura stramonium seeds (maybe even just 1) should be very effective in blocking the nausea of all those you mentioned because their nausea is caused by the same action as that of oral bufotenine, so if it works for oral bufotenine it should work well for all of those.

It will also increase the visuals. Hyoscyamine potentiates the hallucinogenic effects of nearly all psychedelics (even marijuana as you noted).
