I could technically have a bit of alcohol if I used magic to boost my kidney function.
The breakdown of alcohol occurs almost entirely in the liver. To a lesser extent, alcohol and it's byproducts are a stressor to all the other organs, too, so yeah, not great on the kidneys, but not much more than anything else.
This isn't trivia here. It's taught in school and is basically the only popular assumption.
Is this a case where it's a common misconception in the east but completely foreign in the west, like with the nosebleeds? I know there's a genetic component to the liver enzymes involved, but I don't think the basic metabolism of alcohol is entirely different in the two populations.
