now, while the intoxication from smoking datura is not exactly the same as that from drinking a tea (or just eating the herbage), it does have one advantage: it comes on fairly quickly...
when you've had enough from smoking, you're too addled to work a lighter very well...
whereas, dosing orally (or using it topically - see: flying ointment) you may have consumed WAAAAY too much from the first dose, & be ready to drink down a second cuppa before the effects are beginning to be felt at all...
the roots, leaves, seedpods, seeds, flowers - they all have atropine, scopolamine, hyoscine, & similar tropane anticholinergic deleriants...
(& there are quite a few other plants with similar alkaloids in 'em...)
check the many, many newspaper articles on uninformed (or at least, inadequately informed, heh) high school kids "tripping on datura" & ending up in ERs, jails, mental hospitals, or morgues --- i betcha dam' near all of 'em were eating or drinking their poison, & not smoking it...
so...
ya can't spit, ya can't shit, ya can't pee, ya can't cum, ya can't read, ya can't hardly see, ya can't sleep, ya can't wake up, & ya can't tell imaginary from real... & it can last a day, or three days, or a week or longer...
(& some folks are never quite "right in the head" again after surviving a generous overdose...)
sound like fun?
