'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.

From 2008 to 2009, the proportion of non-smokers aged 12 and older who were regularly exposed to second-hand smoke at home remained relatively stable, settling at 6.2% in 2009. The rate had steadily declined since 2003.

A higher percentage of men than women were exposed to second-hand smoke at home (Chart 1).

In 2009, exposure to second-hand smoke at home was highest among 12– to 19–year–olds. The exposure rate for 20– to 34–year–olds matched the national average; all other age groups posted rates below the national average. Men were significantly more likely than women to be exposed to second-hand smoke at home for the 20– to 34–year–olds and those aged 65 and older (Chart 2).

From 2008 to 2009, the percentage of people exposed to second–hand smoke at home remained the same in most age groups—except the 65–and–older range, where it declined.

Only Ontario, 5.3%, and British Columbia, 3.6%, posted rates of exposure to second–hand smoke at home that were below the national average. Quebec, at 9.2%, and Yukon, at 12.0%—which should be interpreted with caution—were above the national average.
