However, there's of course a decent chance that someone spiked them. Hard to tell. On second thought, I could see a deliriant being involved. But from a purely pharmacological perspective, there's little that could have been different between the shrooms. However, if they turned out to be a very weak batch, the dealer could have made an extract if locally available Brugmansia species, that maybe in a low dose could have had effects like this? At least conceivably... I mean if the friend had a similar time course and symptoms? Also her readiness to let her do this to her? The amnesia?
