Women who smoke during pregnancy have low zinc levels in their blood and are more likely than nonsmokers to have babies deficient in zinc. These babies are at higher risk for birth defects and disease than babies who have received adequate amounts of this mineral. These are toxic gases which enter the lungs and bloodstream of the smoker and the surrounding passive smokers, remaining for hours in a smoke-filled room. Inhaling carbon monoxide cuts the oxygen supply to the brain, heart, and other body tissues. Passive smokers, persons breathing second hand smoke, experience more breathing difficulties, eye irritations, bronchitis, pneumonia, and tonsil surgeries.
Smoke increases symptoms of asthma and allergies.
Passive smokers may protect themselves from some of the harmful effects of others' smoke with adequate amounts of vitamin C, beta carotene, vitamin E, and zinc in their diets.
