The prevalence of cannabis vaping among teens in Canada and the United States has doubled in the last seven years, a new study has found.
. The researchers conducted a meta-analysis looking at 17 studies conducted between 2003 and 2020, involving a total of 198,845 North American adolescents 18 years of age or younger.
For Grade 10 students, 10.5 per cent reported having tried vaping cannabis in 2013-2016 while the prevalence in 2012-2020 was 22.9 per cent. Among students in Grades 6 to 9, the prevalence was 3.4 per cent in 2013-2016 and 7.2 per cent in 2019-2020. Vaping devices, also known as e-cigarettes, were initially marketed as a smoking cessation device for adults but have exploded in popularity among teens in the last decade. Most vaping devices are designed to heat nicotine-containing flavoured liquids, but they can also be used to heat and vaporize dried cannabis herbs or cannabis oil.
