Are cigars bad for the health?

In the March 26, 1911 New York Times, Mark Twain was quoted posthumously from a 1905 letter to L. M. Powers in which he wrote, "I know a good cigar better than you do, for I have had sixty years' experience. No, that is not what I mean; I mean I know a bad cigar better than anybody else. I judge by the price only; if it costs above 5 cents, I know it to be either foreign or half foreign and unsmokable.
