Introduction Heated tobacco products (HTPs), such as IQOS, have been introduced in a growing number of international markets. However, little is known about perceptions of HTP products among youth. Methods Data are from wave 1 of the International Tobacco Control Youth Tobacco and E-cigarette Survey (2017), a web-based cohort survey of people aged 16–19 years from Canada, England and the USA. Respondents (n=12 064) were shown an image of IQOS and asked about their awareness, interest in trying and susceptibility to trying the product. Youth awareness, interest in trying and susceptibility to trying IQOS were analysed using descriptive statistics, and logistic regression models were used to examine correlates of these outcomes. Results Overall, 7.0% of youth reported awareness of IQOS (England=5.6%, Canada=6.4% and USA=9.1%) and 38.6% expressed interest in trying the product (England=41.8%, Canada=33.0% and USA=40.9%). Within each country, all key outcomes varied by smoking status: greater proportions of youth who were currently smoking or had a history of smoking reported being aware of, interested in trying and susceptible to trying IQOS. Interest and susceptibility to trying IQOS were associated with male sex, current tobacco use and current e-cigarette use. Across all countries, susceptibility to trying IQOS (25.1%) was higher than for tobacco cigarettes (19.3%), but lower than for e-cigarettes (29.1%). Conclusions Awareness of HTPs, such as IQOS, is emerging among youth in Canada, England and the USA. Interest in trying these products is very high among smokers, but also present among non-smokers.
