Dr. Duane Carr – Professor of Surgery at the University of Tennessee College of Medicine, said this: “Smoking does not discolor the lung.”
Dr. Victor Buhler, Pathologist at St. Joseph Hospital in Kansas City: “I have examined thousands of lungs both grossly and microscopically. I cannot tell you from examining a lung whether or not its former host had smoked.”
Dr. Sheldon Sommers, Pathologist and Director of Laboratories at Lenox Hill Hospital, in New York: “…it is not possible grossly or microscopically, or in any other way known to me, to distinguish between the lung of a smoker or a nonsmoker. Blackening of lungs is from carbon particles, and smoking tobacco does not introduce carbon particles into the lung.”
This was confirmed by Dr Jan Zeldenrust, a Dutch pathologist for the Government of Holland from 1951 – 1984. In a television interview in the 1980′s he stated that, translated from Dutch, “I could never see on a pair of lungs if they belonged to a smoker or non-smoker. I can see clearly the difference between sick and healthy lungs. The only black lungs I’ve seen are from peat-workers and coal miners, never from smokers”.
