Hopefully this doesnt make them ban the damn stuff. Even water can kill if someone drinks too much of it (Im not talking about drowning but rather water poisoning). Anything can be lethal in sufficient doses.
Hey, Di-hydrogen Oxide is dangerous stuff! Just ask a college student!
My mom-in-law was a private duty nurse, she once had a patient who had almost killed herself by drinking an excessive amount of water and not eating. She went on some crazy crash diet and yes, her electrolytes got all messed up.
