Why does the cigarette case say "Smoking is harmful to health"?

Let me answer this question! I had the same question before.

I already know what it is. Here's a story that says-

In the past, after tobacco companies produced tobacco, this word was not written on the packaging. Finally, someone died of smoking. So someone sued the tobacco man and lost a lot. So in the end, the tobacco company wrote' smoking is harmful to health' on the packaging when producing. Even if someone dies of smoking, his responsibility is irrelevant. Why? Because I wrote it. -harmful to health, you smoked to death. Who can you wish for? This is the answer.
