Frequently Asked Question

What are the dangers of environmental (secondhand) tobacco smoke?

Environmental tobacco smoke (ETS) is also known as secondhand smoke. Passive smoking (inhaling secondhand smoke) happens when non-smokers breathe other peoples tobacco smoke. This includes mainstream smoke (smoke that is inhaled and then exhaled into the air by smokers) and sidestream smoke (smoke that comes directly from the burning tobacco in cigarettes, pipe or cigar especially the end part of it). ETS contains the same harmful chemicals as the smoke that smokers inhale. In fact, because sidestream smoke is formed at lower temperatures, it has even larger amounts of some toxic and cancer-causing substances than mainstream smoke.

There is strong evidence that ETS causes serious damage to human health. Each year about 3,000 non-smoking adults die of lung cancer as a result of breathing secondhand smoke. ETS causes about 35,000 deaths from heart disease each year in people who are not current smokers. It can also affect non-smokers by causing asthma and other respiratory problems, eye irritation, headaches, nausea, and dizziness.

Children whose parents smoke are more likely to suffer from asthma, pneumonia, bronchitis, ear infections, coughing, wheezing, and increased mucus production. Babies of parents who smoke have a greater chance of dying of sudden infant death syndrome (SIDS). Pregnant women exposed to ETS are at risk for having a low birth weight baby and may also be at risk for pre-term delivery and miscarriage.

Secondhand smoke is involuntarily inhaled, lingers in the air hours after cigarettes have been extinguished, and can cause a wide range of adverse health effects, including cancer, respiratory infections, and asthma. The current Surgeon Generals Report concluded that there is no risk-free level of exposure to secondhand smoke. Even short exposures to secondhand smoke can cause blood platelets to become stickier, damage the lining of blood vessels, decrease coronary flow velocity reserves, and reduce heart rate variability, potentially increasing the risk of heart attack.

My advice

So, non-smokers beware of those smokers, they are threatening your health, stop them from smoking for your own sake.
