In 2017, 15.7% of people aged 18 to 64 who were employed reported having been exposed to secondhand smoke from others in the past 30 days indoors at their workplace. This proportion has remained stable since 2014. Blue-collar workers were the most likely to report exposure (27.4%); managers and professionals were the least likely (6.4%). In 2018, among those aged 18–75, 17.6% reported that someone smokes inside their home: 12.5% regularly, 5.1% occasionally. Since 2014, the proportion of 18- to 75-year-olds reporting that someone smokes inside their home has decreased by 10 percentage points. The decline in smoking at home is particularly marked among daily smokers, with a 14-point drop, whether among smokers of fewer than 10 cigarettes per day (from 44.4% in 2014 to 30.8% in 2018) or 10 or more cigarettes per day (from 62.5% to 48.4%). Among smokers living in a household with a child, the frequency of smoking at home was cut in half between 2014 and 2018, but it remains high: from 31.6% to 14.4% when a child under 4 is present, and from 48.5% to 23.8% when a child aged 4 to 18 is present.
