Another nuance that most people don't understand is that there are different levels of "badness." There's a difference between "cigarettes cause cancer" and "phones cause cancer". The former is very definitely true, confirmed by many studies, and the health impact is very significant. The latter is probably untrue (there are studies that go both ways, but the vast majority say "no cancer"). Even if there's any impact, it's extremely minimal when compared to cigarettes. People can't distinguish between those two levels of "causes cancer" in a headline.
