This is the USA, if I ask a pharmacist if I can drink Epsom Salts , he's gonna think I'm nuts and worry about getting sued. Now if some drug company puts it inside a capsule, then it's fine to poison you that way.
However, I've never heard of anything as whacked as eating Epsom Salts , I alwalys thought it was hazzardous stuff. But so is anything you buy in a box at the supermarket.
