  • People who already have heart disease are at especially high risk of suffering adverse effects from breathing secondhand smoke and should take special precautions to avoid even brief exposures.
  • Breathing secondhand smoke can cause lung infections such as pneumonia and bronchitis, especially in children.
  • Other breathing problems include coughing, mucus, chest discomfort, and reduced lung function.

family with dog  in grassDo not allow smoking in your home, car or around your children. Using fans, exhaust systems, air cleaners or opening windows does not eliminate all the toxins from tobacco smoke and cannot keep you or your family safe. It can take three or more hours for the smoke of one cigarette to clear a room or confined space.Tobacco smoke will travel from room to room or unit to unit through doors, windows, plumbing, electrical outlets, crawl spaces and attics. The only way to eliminate the risk of secondhand smoke is to stay away from secondhand smoke.
