Because all the people taking it for COVID (and probably trying to cure cancer) were not getting it from the doctor. They were getting it from Farm supply stores . Everyone was calling it horse dewormer because that's what it was. They were not going to get a prescription. I know because I live amongst these dummies that were asking on Facebook which one to get from the farm supply, what flavor was best, etc.
We REALLY need to stop letting football coaches teach history in public education.
