Genetic factors in smoking also increase risk of chronic bronchitis

Smoking is a known risk factor for respiratory diseases like chronic bronchitis, but genes also play a significant role in its development, according to researchers in Sweden, who studied more than 40,000 Swedish twins to determine the extent to which behavior, environment and genes each play a role ion the development of chronic bronchitis.
