We investigated how use of heated tobacco products (HTPs) affects tobacco cessation in a Japanese workplace. We offered cessation programmes for 158 tobacco users from November 2018 to April 2019 and surveyed the quitting rate in August 2019. Successful quitting was defined as stopping use of all kinds of nicotine-containing tobacco products. A Poisson regression analysis adjusted with inverse probability weighting showed that HTP users (either exclusive HTP users or dual users) were less likely than exclusive cigarette users to quit tobacco (risk ratio, 0.77; 95% CIs 0.61 to 0.97, p=0.024). The use of HTPs should not be recommended to assist in smoking cessation. Trial registration UMIN000034719.
