Objectives: We aimed to examine the association between initial smoking cessation treatment and abstinence using databases of medical insurance and annual health checkup.
Methods: We conducted a retrospective explanatory analysis of data from a Japanese medical claims database, which included information from private insurers from April 2005 to December 2019. During the period when the response to the question on habitual smoking in annual health checkups changed from “yes” to “no”, the patients were divided into two groups: those who received smoking cessation treatment and those who did not received smoking cessation treatment. We compared the proportion of individuals maintaining smoking abstinence at annual health checkups between the two groups retrospectively.
Results: We included 7,766 participants with complete health checkup data for 3 years in the primary analysis, with 505 and 7,261 participants in the treatment and non-treatment groups, respectively. Individuals in the treatment group were 8%–9% more likely to abstain from smoking for 1, 2, and 3 years from the quitting index date; the risk ratio remained significant from the first to the third year.
Conclusions: These results suggest that the group that received smoking cessation treatment was expected to maintain smoking cessation in the long term compared to the group that achieved smoking cessation without treatment.

Objective: We conducted a questionnaire survey to clarify headaches caused by the smoke and odor of heated tobacco products.
Methods: A questionnaire survey was conducted on the internet. The subjects were patients with headache aged from 20s to 40s, they were not limited to heated tobacco users.
Results: The number of valid responses was 627, which included 163 with migraine and 464 with other headaches. Migraine had a greater influence on daily life than other headaches, and the migraine group was significantly more likely to have headaches caused by the smoke and odor of cigarettes and heated tobacco products than the other headache group. In the migraine group, more non-smokers (n = 117) had headaches caused by the smoke and odor of heated tobacco as well as cigarettes than smokers (n = 46).
Conclusions: Among headache patients, it was clarified that migraine patients are more likely to have headache induced by the smoke and odor of cigarettes and heated tobacco products both by smoking and secondhand smoke. It is necessary to create a non-smoking environment without distinguishing between cigarettes and heated tobacco.
