'Passive smoking,' or exposure to second-hand smoke, has negative respiratory health effects. Two of the most common associated diseases are lung cancer in adults and asthma among children.

The proportion of non-smokers aged 12 and older who were regularly exposed to second-hand smoke at home has declined since 2003, reaching 5.9% in 2010.

More men than women were exposed to second-hand smoke at home (Chart 1).

Young Canadians aged 12 to 19 made up one-third of the 1.3 million non-smokers who were regularly exposed to second-hand smoke at home, even though they only made up one-eighth of the total group of non-smokers.

In 2010, 14.9% of young Canadians aged 12 to 19 were exposed to second-hand smoke at home—falling from 23.4% in 2003 to 15.5% in 2008 and not changing significantly since (Chart 1).
