There was actually a lawsuit won in California that roasted coffee has carcinogenic compound however the state regulators quashed it. I'm surprised people don't continue to make a bigger deal about this. Why did the judge agree that it needs a warning?
Pretty much everything has carcinogenic compounds, that doesn’t mean all that much. Coffee has been consumed for multiple decades by a large percentage of the world’s population. Any significant negative effect would be trivial to identify.
