Passive smoking

Passive smoking means breathing other people's second-hand tobacco smoke. Passive smoking is damaging because it increases risk of poor health including heart disease and cancer. People frequently exposed to second-hand tobacco smoke:

  • are at 20-30% higher risk of lung cancer than people who are not exposed
  • are exposed to more than 4,000 chemicals in the smoke - 69 are known to cause cancer
  • are at high risk of premature death
  • have a high risk of heart disease.

There is no known safe level for second-hand passive smoke. In children, passive smoking also causes lower respiratory illness and contributes to the symptoms of asthma.
