The number of Canadian teens who regularly vape nearly doubled in one year, coinciding with the first rise in cigarette-smoking rates in that age group in years, according to a new study that provides the first evidence of how vaping rates changed after they were legalized and new companies entered the market.
The findings, published in the British Medical Journal on Thursday, are based on surveys of Canadian 16- to 19-year-olds conducted in 2017 and 2018. The surveys found the number of teens who reported vaping in the past week rose to 9.3 per cent in 2018 from 5.2 per cent in 2017. The number of those who said they had vaped in the previous month rose to 14.6 per cent in 2018 from 8.4 per cent in 2017.
At the same time, the surveys found the number of 16- to 19-year-olds who smoked cigarettes in the past week rose to 11.9 per cent in 2018 from 7.6 per cent in 2017. The number of teens who reported smoking in the past month rose to 15.5 per cent in 2018 from 10.7 per cent in 2017.
