Classic Weasel Wording. Like saying "too much of X" to imply something is deadly by it's very nature, when the words "too much" all by themselves are the metric for dangerous usage. Too much oxygen is deadly. Too much water is deadly. Because that's what "too much" means. Yet without either, we'd die. "If used incorrectly" is just another way to say "Too much". With enough creativity, anything "used incorrectly" could be dangerous. It's Fake News speak and in a supposed public health crisis like this, those that uttered this lie should be hanged.
