Highlights
- In our cohort study in Japan, dual users of both cigarettes and HTPs, tended to smoke/use more tobacco products when they started to use HTPs.
- FEV1 appears to have declined more strongly in these dual users than in the combustible cigarette-only smokers and HTP-only users.
- Individuals who switched to HTP-only use a mean of 1.7 years before had a similar reduction in FEV1 as those who had exclusively smoked cigarettes.
- This study could provide evidence that dual users should be addressed as a high-risk group when tobacco policies for HTPs are considered.
