Have you ever violated US federal law by using a product in a manner inconsistent with its labeling?

I’ve used a product in a way inconsistent with its labeling, but I do not believe I’ve ever violated a federal law. At least, not one that would stand up in court.

It’s a really dumb phrase. Why not just say, “Disregard the written instructions at your own risk”? This sort of thing makes a mockery of federal law.

In fact, I’ll ask that in the original thread.
