Cigarette smoking and hearing loss
Cigarette smoking may cause hearing loss. Smokers are nearly 70% more likely than non-smokers to suffer hearing loss, according to a study including more than 3,000 people. Another study found otherwise, absolving cigarettes from blame in hearing loss. The first study, conducted in the United States and published in the Journal of the American Medical Association, June 1998, concluded that the risk of hearing impairment often increases with the number of cigarettes smoked.
