Prevalence trends and factors associated with vaping in Ontario (2015 to 2018) and Quebec (2017 to 2019), Canada

Robust surveillance of vaping product use (with or without nicotine) in Canada has been limited by use of multiple tools with varying designs and content. The objective of the current study was to examine trends over time in vaping prevalence and to examine associated factors, using data from the Canadian Community Health Survey (CCHS). Trends in the prevalence of past-30-day vaping over time were examined using data available from optional modules of the CCHS, for Ontario from 2015 to 2018, and for Quebec from 2017 to 2019.
