A lot of ethanobotanists report that peoples using datura traditionally or spiritually (eg in the context of Ayurvedic medicine) don't tend to experience as many negative effects as people using it recreationally:

But with that said, I would strongly caution people not to take tropane deleriants. Unless you really know what you're doing, there's a solid chance you are going to end up being high for way too long or end up in the hospital.
I'll also caution codr7 that seeds (especially from different sources) can have hugely different potencies, so be careful dosing anything via seed, especially something as serious as datura. It sounds like this works for you, so I don't intend to sound patronizing: I just want to make sure that I am spreading harm reduction everywhere I go, and datura/tropane alkaloids can be very dangerous.
