Filtered 'Light' Cigarettes Pose a Serious Danger


Evidence from a new study suggests ventilation holes in the filters of some cigarettes contribute to higher lung cancer rates and risks. Peter G. Shields, MD, deputy director of the Comprehensive Cancer Center at James Cancer Hospital and a professor at the Ohio State University, co-authored the recent report, which was published in the Journal of the National Cancer Institute.

These holes were first incorporated into light cigarette filters in the 1960s to make the cigarettes “safer” by allowing smokers to draw in air along with the tobacco smoke. But, according to Dr. Shields, today's cigarettes are even more risky when it comes to lung cancer.

Since filtered cigarettes were introduced, rates of adenocarcinoma—a type of lung cancer that develops in the outer edges of the lungs and is often difficult to treat—have increased significantly. This type of lung cancer now makes up more than 80 percent of new lung cancer cases—a fact that researchers report is "highly suggestive" of a causal relationship between cigarette filters and adenocarcinoma of the lungs.
