Implications for public health will depend on trends in use, including overall use, and who is using these products. This study examined differences over time (2017-2019), across countries (Canada, England, the United States (US)), and by smoking and vaping, in use of other tobacco/nicotine products and overall use. METHODS: The study includes online repeat cross-sectional surveys of youth aged 16-19 years in Canada (N = 11,714), England (N = 11,170), US (N = 11,838) in 2017, 2018, and 2019. Past 30-day use of tobacco/nicotine products (any, cigarette, e-cigarette, other combusted [cigars/cigarillos/waterpipe], other non-combusted [smokeless tobacco/nicotine replacement therapies) were examined by country, year, and, for other combusted and non-combusted products, past 30-day cigarette smoking and vaping. Use of emerging products (IQOS, nicotine pouches) was explored in 2018-2019. RESULTS: From 2017 to 2019, use of any product increased in Canada (17.1%-23.2%, AOR = 1.07 [95% CI = 1.04-1.09]) and the US (18.0%-24.0%, AOR = 1.06 [1.04-1.09]) but not England (20.8%-21.7%, AOR = 1.01 [.99-1.03]). Use of other combusted products (cigars/cigarillos/waterpipe) showed little change (Canada: 8.1%-7.8%; England: 6.3%-7.3%; US: 8.6%-8.5%; p ≥ .151). Use of other non-combusted products (smokeless/nicotine replacement therapies) increased in all countries (Canada: 1.5%-3.2%, AOR = 1.02 [1.01-1.02]; England: 1.4%-2.6%, AOR = 1.02 [1.01-1.03]; US: 3.3%-4.9%, AOR = 1.02 [1.01-1.02]). Vaping increased in all countries (Canada: 8.4%-17.8%; England: 8.7%-12.6%; United States: 11.1%-18.5%; all p < .001). Smokers and vapers reported greater use of other combusted and non-combusted products than those who neither smoked/vaped (p < .001). Emerging product use was rare (≤1.5%). CONCLUSIONS: Youth past 30-day tobacco and nicotine product use increased from 2017 to 2019 in Canada and the United States, largely due to increases in vaping and other non-combusted products. "Other" tobacco/nicotine products were used predominantly by youth who smoked cigarettes and/or vaped.
