Not gonna try to dissuade you from your disinterest, nor do I want to continue this derailment I have contributed to, but I'd like some more details about these experiences. Throw me a PM or something. How much previous datura experience did these people have, had they tested the alkaloid content of the plant through titration of homogeneous material harvested all at once, what part of the plant did they use (whether it was in its growth or generative phase also matters, well obviously seeds and flowers can only be gathered in the latter though), how much plant matter had to be used to achieve desired effect level in previous experimentation, what species of datura was it, etc. etc.? Effects on the combined experience relative normal also being a matter of interest, of course.
