Some people inhale, most don't. People shouldn't, but you know an interesting factoid is that the average US woman will consume (eat) 4lbs of lipstick in her lifetime without intentionally doing so. So too, cigar smokers invariably will be inhaling more cigar smoke by virtue of being around it and having it in their mouth than someone not smoking a cigar. Is the amount material to your health? That's the gamble you get to decide on.
This article talks about how it's not 7lbs, it's only 3.7 pounds of exposure (risk of ingestion and absorption) based on estimates and shows their math.
I'm guilty of forwarding a tenuous idea by repeating the 4 pound statement and not explaining the assumptions, but hell, even if it's 1 pound it's still a hell of a lot more than I ever assumed, though keep in mind it's over a lifetime (seven-eight decades).
Point was simply that exposure == some fractional consumption. Smoking a cigar certainly is not healthier for your lungs than abstinence even if you don't deliberately inhale.
