In my opinion, it all depends on what you are taking in when you smoke the cigar. Many cigars that people may call "low quality" are pure tobacco. I can't see where there would be much of a health difference between those and higher end cigars except to the degree that that fertilizers may have an affect.

Cigars with additives, well, it depends upon the additive doesn't it? Inhaling smoke with sugar residues could be bad, especially long term.
