Smoking is bad.
But breathing somebody else's smoke may be even worse. Steve Busalacchi explains. When a smoker inhales, the cigarette filter stops some of the most harmful substances in the burning tobacco. But the State Medical Society of Wisconsin's Doctor Kesavan Kutty says the person standing next to the smoker breathes the burning fumes from the lit part of the cigarette. The Milwaukee lung disease specialist says the smoke contains especially harmful substances that cause cancer and other problems.
