btw i found this simply by searching wikipedia for “activated charcoal”. it’s not particularly hard to find information instead of just shooting your mouth off.
unfortunately there’s a tendency among people on the internet to think that a more extreme version of a correct statement must therefore be more correct
kind of like how “nicotine interferes with oral estrogen administration” got turned into “if you smoke anything at all and take estrogen in any way at all it will render the estrogen ineffective”
