I get the sarcasm, but would this be legal? It's satire if it's not actually known as a carcinogen, and a legal requirement if it is. It would dilute the warning in the public's perception, but companies might find it cheapest and easiest to just stick it on everything.

The “warning” is already as diluted as the coffee in question, and has been seen by many as a joke for years now.

If something is carcinogenic is always a matter of volume. Most things are carcinogenic if consumed in quantities large enough. Most things carcinogenic if aerosolized and inhaled. Most things are carcinogenic if left on your skin long enough.

Anything can be a carcinogen if ground finely enough and inhaled.
