NEW YORK  - Any exposure to secondhand smoke reduces lung function in patients with cystic fibrosis, according to investigators at Johns Hopkins University School of Medicine. The adverse effects related to this noxious exposure are magnified by certain gene variants, the team reports in the Journal of the American Medical Association.
