Ive got that crap groing next to my house, its been there since I was born (18 years ago). I have never tried it and never will try it. There is all different types of datura, heres some pics of the tree. Please note that the plant is not in season atm, down here in aus spring starts at the end of this month its still winter. The tree is normally covered in yellow trumpet flowers and the pods and seeds turn brown.
Hope this helps guys.
