ill sell you one of the plants and you can make the tea for you self, then tell us if you were able to cut your little guy off!
just for fun, angels trumpet is the name for the plant more properly called DATURA. it has trumpet shaped flowers, developing into seed pods covered in spines. that btw, also gives it its other nick name, thorn apple, and for its hallucinogenic properties, devils apple.
it is related to the nightshade family of plants, including the tomato and tobacco plant.
the effects of ingesting datura are probably the only TRUE hallucinogenic effects that a plant can offer. however the experience is more like a delerium, and there is probably LITTLE chance of having a positive experience on this substance.
