I have alot of experiance with datura meteloides is a close relative of datura stominium it also contains scolpamine and atropine the anti cholernigenic chemicals that cause the dilusional effects it is not worth experimenting with it is a very dangerous plant many people I went to high school with ended up in mental hospitols with wild plants it is very difficult to determine dosages as the concentrations of these alkaloids can very greatly from soil typew and minerals within the soil take my advise stay away from this one unless u have trained in its use under an experianced shaman
