Tobacco Facts. Sometime giving up is good. Quit smoking.

Passive smoking

Passive smoking means breathing in other people’s tobacco smoke. A smoker’s exhaled smoke is called exhaled mainstream smoke. The smoke drifting from their lit cigarette is called sidestream smoke. The combination of mainstream and sidestream smoke is called environmental tobacco smoke (ETS).


Pregnancy and newborn babies

Health risks for mothers who smoke during pregnancy include:

  • Increased risk of miscarriage and stillbirth
  • Increased risk of premature birth and low birth weight
  • Increased risk of sudden infant death syndrome (SIDS)
  • Increased risk of complications during the birth.
  • A non-smoking pregnant woman is more likely to give birth to a baby with a slightly lower birth weight if she is exposed to environmental tobacco smoke in the home – for example, if her partner smokes.


Health risks – children

  • A child who lives in a smoking household for the first 18 months of its life has an increased risk (around 60 per cent higher) of developing a range of respiratory illnesses including croup, bronchitis, bronchiolitis and pneumonia. They are also more prone to getting colds, coughs and glue ear (middle ear infections). Their lungs show a reduced ability to function and slower growth.
  • A child exposed to environmental tobacco smoke in the home is 40 per cent more likely to develop asthma symptoms. Estimates suggest that about eight per cent of childhood asthma cases are caused by passive smoking.


Health risks – partners who have never smoked

People who have never smoked but who live with partners who smoke are at increased risk of a range of tobacco-related diseases.

Some of the many health risks for partners who have never smoked include:

  • Passive smoking increases the risk of heart disease. There is consistent evidence that non-smokers married to smokers have higher risks of coronary heart disease than those whose spouses do not smoke.
  • Long term exposure to passive smoking may lead to the development of atherosclerosis (narrowing of the arteries). Just 30 minutes of exposure to environmental tobacco smoke can start this process.
  • Non-smokers who suffer long term exposure to environmental tobacco smoke have a 20 to 30 per cent higher risk of developing lung cancer than non-smokers who are not exposed to passive smoke.
  • The National Health and Medical Research Council (NHMRC) has estimated that 11 people who have never smoked die from lung cancer each year in Australia, and up to 77 people die from coronary heart disease, because they are exposed to smoke at home.
  • There is an increased risk of nose and sinus cancer.
