We do need to be a little careful here. Just because something is banned elsewhere doesn't mean it should have been. It does raise a lot of questions as to why there is a difference, however. Reversed stupidity isn't intelligence. The real crime here isn't that something is allowed in the US that is banned elsewhere. The real crime is covering up and censoring data, mandating the thing, and well... just the FDA in general. If we were to set our standards on what to ban based on other countries, things like guns, nuclear plants, free speech would be the top of the list.
