Deaths from A. muscaria have been reported in historical papers, but fatal poisoning from eating this mushroom is very rare nowadays. Much of this has to do with current medical advancements and the ability to combat kidney failure and the like. Translation -- the mushroom is still quite toxic, but we've gotten better at treating the person poisoned. Most ingestions of this mushroom occur from people seeking a hallucinogenic experience. They do get that experience, and a lot more they didn't plan on.
