We can always use more case studies of insanity that aren't religion, right?
Well, Miracle Mineral Supplement is my new go-to example for Bad Things happening to people with low epistemic standards. "MMS" is a supposed cure for everything ranging from the common cold to HIV to cancer. I just saw it recommended in another Facebook thread to someone who was worried about malaria symptoms.
It's industrial-strength bleach. Literally just bleach. Usually drunk, sometimes injected, and yes, it often kills you. It is every bit as bad as it sounds if not worse.
This is beyond Poe's Law. Medieval blood draining via leeches was far more of an excusable error than this, they had far less evidence it was a bad idea. I think if I was trying to guess what was the dumbest alternative medicine on the planet, I still would not have guessed this low. My brain is still not pessimistic enough about human stupidity.
There are two things going wrong here. The first problem is failing to call things by their true names. This is a widespread problem when people use drugs and supplements: they refer to them by slang terms or brand names. This cuts them off from information; if they knew it was bleach, they'd think twice before using it. There was a similar problem with "bath salts" (a term that does not identify a drug, but rather means "unidentified substance that's labeled as maybe poison".)
The second problem is failing to observe the first level of precaution, which requires, at a minimum, doing some internet research, either being qualified or consulting someone qualified to judge the risks and benefits, and knowing how to measure out a correct dose and what the consequences are if you screw it up. (This last one appears to have killed some people: they didn't water the bleach down enough to be survivable).
I will say this, though: it makes the quacks promoting ascorbic acid (vitamin C) for everything look a whole lot better by comparison.
