Introduction Philip Morris International introduced ‘IQOS’ to the Korean market in June 2017. To monitor the use of IQOS among young Korean adults, we identified their awareness, experience and current use of IQOS.
Methods Three months after the introduction of IQOS in Korea, we conducted an online survey with 228 general young adults, aged 19–24 years.
Results 87 participants (38.1%) were aware of IQOS, 13 (5.7%) were IQOS ever users and 8 (3.5%) were current IQOS users. All the current IQOS users were triple users of conventional cigarettes and electronic cigarettes (e-cigarettes). There were no IQOS-only users and one IQOS ever user was a non-cigarette smoker. Among the eight current IQOS users who smoked 9.1 conventional cigarettes a day on average, four smoked 10–20 HEETS sticks a day. The current IQOS users decided to use IQOS because they believed it was less harmful or to stop smoking. The current conventional cigarette smokers were much more likely to be aware of IQOS (OR 4.496; 95% CI 2.185 to 9.250) and to be IQOS ever users (OR 11.649; 95% CI 1.024 to 132.564).
Conclusion Awareness, experience and use of IQOS among young Korean adults were relatively higher than among their Japanese counterparts. Current IQOS users were more likely to smoke conventional cigarettes and/or e-cigarettes, which contradicts the tobacco industry’s claims that conventional cigarette smokers will switch to heated tobacco products. Until obtaining robust evidence concerning heated tobacco products, the government should regulate the tobacco industry’s marketing tactics and health claims.
