Exposure to second-hand smoke at home, 2011

'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 5.5% in 2011.  This rate is unchanged from 2010.

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

In 2011, 12.6% of young Canadians aged 12 to 19 were exposed to second-hand smoke at home — falling from 23.4% in 2003 (Chart 1). This age group is the most likely to be exposed to second hand smoke at home. Of the 1.27 million non-smoking Canadians aged 12+ who were regularly exposed to second-hand smoke at home, the 12-19 year-old age group made up 29.4%.

In 2011, exposure to second-hand smoke at home was highest among those aged 12 to 19. Men aged 20 to 34 were significantly more likely than women to be exposed to second-hand smoke at home; however, there was no significant difference between the sexes in other age groups (Chart 2).
