Some advice, just throw that shit out before you do something foolish.
When I was really bored in high school a long long time ago, I ordered some Datura seeds from jlfcatalog.com (and some morning glory seeds, syrian rue, salvia divinorum - back before Youtube made it popular). I had fun with all of it except for the Datura, because my judgment got the better of me (and my friend's Dad, who is a doctor and former tripper from the 70s, found them and explained that the scopolamine in the seeds could kill me, and that I was a "fucking retard" if I thought about eating them.)
Datura will not make you "trip" like lsd or shrooms (i.e. hallucinate) it will make you fucking nuts - "anticholinergic delerium" - check wikipedia to see the difference. The chemicals in the Datura seeds (Scopolamine) has an anticholinergic effect on your brain and messes with acetylcholine. I'm not a biochemist, but this is more similar to a Benadryl trip than lsd or shrooms (Benadryl/diphenhydramine hcl also has anticholinergic properties except that Benadryl will make you extremely drowsy - so the delusions can seem like dreams), and it doesn't last nearly as long as Datura (which apparently can be upwards of 18-24 hours or longer).
I haven't taken Datura, but I have taken 15 Benadryl in a sitting. I thought I was in my dorm with my buddies playing PS2. In reality, I was curled up in a fetal position mumbling gibberish to myself in a dark, empty room. I don't remember much of it, except that I was happy to finally fall asleep, and I never ever repeated the experiment.
But seriously, this shit could make you crazy for a day or more. I know you are probably bored (I was when I looked up all the crazy legal high shit) but you gotta focus on something other than Datura (and anticholinergics generally, in my opinion).
