I am an infectious diseases physician who lost his vocal cords because of throat cancer which is often caused by smoking.
One of the adverse effects of smoking is an increased rate of respiratory tract infections. There are multiple mechanisms that account for the increased rate of respiratory infections in smokers and their children. Tobacco smoke compromises the anti-bacterial function of leukocytes, including neutrophils, monocytes, T cells and B cells, providing a mechanistic explanation for increased infection risk. Also exposure to smoking increases the colonization by respiratory pathogens and subsequently the occurrence of upper respiratory tract infections. This is believed to be due to the fact that the mouth of smokers contains fewer organisms with interfering activity against bacterial pathogens. They can spread their “bad bacteria” to their children and other household members. The high number of pathogens and the low number of interfering organisms found in the nasopharynx of smokers reverts to normal levels after complete cessation of smoking. We have done research that shows this phenomenon.
