Prevalence of vaping and smoking among adolescents in Canada, England, and the United States: repeat national cross sectional surveys
Resource Notes:
Study noted increased youth vaping, particularly with regards to experimentation, and claimed an increased youth smoking rate.
Controversies:
Canadian sample pool showed a statistical ethnicity change between wave 1 (2017) and wave 2 (2018) that was not reflected in the UK and U.S. Sample pools.
Claims of increased smoking rates were not reflected in Statistics Canada data released shortly after this study was published.
Lead author selectively released portions of this data to officials and news media prior to completion of peer review and publication of the study driving a significant narrative and reaction prior to full publication of all data.
