    BackgroundThis study assesses differences in social norms towards smoking and vaping among youth across countries (England, Canada, US) and smoking and vaping status.MethodsData are from the 2017 ITC Youth Tobacco and Vaping Survey, among youth age 16-19 in England (N = 3444), Canada (N = 3327), and US (N = 3509). Prevalence of friend smoking, friend vaping, peer approval of smoking, and peer approval of vaping were estimated. Adjusted logistic regression models were estimated for each norm to assess associations with country, smoking status, and vaping status, adjusting for sociodemographics, alcohol use, and marijuana use.Results47% and 52% reported friend smoking and vaping respectively. Perceived peer approval of vaping (44%) was almost double that of smoking (23%). Compared with England, fewer Canadian and US youth reported friend smoking (Canada: AOR = 0.71 [95% CI = 0.62-0.82]; US: AOR = 0.54 [0.47-0.62]) and peer approval of smoking (Canada: AOR = 0.74 [0.63-0.87]; US: AOR = 0.78 [0.67-0.91]), yet more reported peer approval of vaping (Canada: AOR = 1.23 [1.08-1.41]; US: AOR = 1.30 [1.14-1.48]). More Canadian than English youth reported friend vaping (AOR = 1.17 [1.02-1.36]). Friend smoking, peer approval of smoking, and friend vaping were more common among smokers and vapers (all p < .02). Peer approval of vaping was more common among vapers but less common among smokers (all p < .044).ConclusionsYouth had more positive vaping than smoking norms. English youth reported the most pro-smoking but least pro-vaping norms in adjusted models; this was unexpected given country differences in regulatory environments. Norms towards both products were associated with use, with some evidence of cross-product associations between norms and behaviours.Copyright © 2019 The Authors. Published by Elsevier B.V.
