It's my understanding that hookah is more of a vaporization than combustion (the heat source never directly touches the tobacco, hence the foil or metal screen and air buffer between the charcoal and shisha). once the shisha starts to actually burn, it's time to empty the bowl. therefore, it's dificult to compare the two, as obviously cigars require combustion. it would be more appropriate to compare it to an e-cig, which again is difficult, but at least then you're comparing granny smiths to macintosh's. just this one fool's thoughts
