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.
