You're a fucking idiot if you ingest belladona, brugmansia, angels trumpet or similar. There is NO way to guage the potency of plant, and the levels of active alkaloids can vary greatly from one plant to another. The safest way to take this plant is to smoke it like a ciggerette, remove any hard cornered furniture from the room, and always make sure to have a sitter that is big enough to hold your ass down.
