Even Low Tobacco Smoke Exposure Is Risky

Aug. 20, 2010 -- Even low levels of tobacco smoke exposure pose a risk to lung health, triggering potentially hazardous genetic changes, according to a new study.

The hazards of secondhand smoke have been known for years, says researcher Ronald Crystal, MD, chief of the division of pulmonary and critical care medicine at New York-Presbyterian/Weill Cornell Medical Center and chair of genetic medicine at Weill Cornell Medical College, New York. ''But there were never any studies that had looked at the biology, why this is the case."

His study does that, demonstrating that even the lowest levels of smoke exposure lead to genetic changes at the cellular level in the lungs. "What this study shows is, if we could detect nicotine in the urine, we could also detect changes in the number of genes turned on and off'' in the cells of the lungs, Crystal tells WebMD.

The new findings put ''scientific teeth" behind the epidemiological evidence that smoke exposure even at low levels is hazardous, says Zab Mosenifar, MD, a pulmonologist, director of the Women's Lung Institute, and executive vice-chair of the department of medicine, Cedars-Sinai Medical Center, Los Angeles, who reviewed the study findings for WebMD.

The study also suggests that those ''casual'' smokers who think smoking a few cigarettes a week is not hazardous are incorrect, according to the researchers.
