done quiet a bit of researchin on datura (well mainly jus readin peoples experiences) almost every trip i read bout always had people hallucinatin they had mates/family members come over to see them and started talkin to them then when they looked away for a split second they were gone. most people say after they tried it they regret doin it.. its the most best and worse drug there is (mainly worse) most people have had bad trips from datura n had to go to hospital to get some tube thing stuck up their dick or somethin so they can drain their bladder cause aparently it is impossible to piss whilst on datura.. plus all the other shit they do to you in hospital n the hospital bill is usually around $10,000.

you should of at least given some info like how old you are, how much you wiegh,gender etc.. cause then people would have a better idea of how much is right for you from what i read i doubt it would be safe for someone under 25 years to try it (although i cant even be sure bout that imo it aint safe for anyone to try it).. heard from someone a couple of kids around 16 tryed it n died.. this plant is not to be fucked wit. if your gonna do it cause your bored or somethin then leave it.

btw your question bout the seeds dependin on the type of datura you got (theres Datura stramonium, Datura Inoxia n a few others) so you really cant tell how much would be right.

before tryin it i suggest you go here http://www.erowid.org/experiences/subs/exp_Datura.shtml
