Objective: In accordance with the amendment to the Health Promotion Act in July 2018, smoking has been banned, in principle, on a university campus since July 2019. Under certain conditions, however, outdoor smoking areas have been approved. The aim of this study was to survey student attitudes toward smoking on campus, including the perceived need for the university to establish its own rules and regulations controlling smoking.
Method: Participants in this study were second-year students enrolled at Nayoro City University in 2019. The survey was conducted via an anonymous, self-administrated and semi-structured questionnaire that included questions concerning attitudes toward smoking on campus.

Results and Discussion: Recovery rate was 90.1% and all respondents claimed to be non-smokers except two former-smokers. Seventy nine point one% of respondents agreed on the need for the university to set its own rules controlling smoking. Sixty seven point nine% of them also replied that these rules should ban smoking on the streets next to the campus. These replies might be due to the low prevalence of smoking among respondents. By contrast, 62.2% of respondents gave their approval for creating outdoor smoking areas. This might be related to second-hand smoke exposure in their part-time work places.
Conclusion: The majority of students showed approval for the establishment of university-based rules and regulations controlling smoking on the campus.

Objective: The aim of the study was to measure the concentration of fine particulate matter (PM_2.5) in hotel air and assess guest exposure to passive smoking.
Methods: We measured PM_2.5 concentration outside the business hotel X, in the non-smoking lobby, and in the hallways of both the non-smoking and smoking floors. The PM_2.5 of smoke from a guest room on the smoking floor was measured from the hallway in front of the room.
Results: The PM_2.5 concentration in the hallway of the smoking floor was significantly higher than that outside the hotel, in the lobby, or on the non-smoking floor. Also, the PM_2.5 concentration on the non-smoking floor was significantly higher than that in the lobby. When someone smoked, the PM_2.5 concentration in the hallway in front of their room rose two to three times than before. The average PM_2.5 value on the smoking floors exceeded the average annual value stipulated by the Ministry of the Environment.
Conclusion: The PM_2.5 concentration was high not only on the smoking floors, but on the non-smoking floors as well. It is possible that the cigarette smoke spread through the elevators and stairwells. Further, when a smoker lights a cigarette in their room, it is possible that PM_2.5 may leak into the hallway through gaps of the door in the guest room door. Therefore, passive smoking cannot be avoided even in hotels with smoking and non-smoking floors.

Even today psychiatric hospitals are exempted from smoke free environment. But with the implementation of the amended Health Promotion Act of the July 1st, 2019, all the hospitals in Japan including psychiatric ones became in principle smoke free in their premises.
We intended to share the information and problems for making hospital smoke free and to execute the hospital total smoking ban smoothly among the psychiatric hospitals in Kyoto Prefecture.
We send a questionnaire to psychiatric hospital administrators in Kyoto Prefecture before and after the enforcement of the Act.
Before the implementation, five to twelve (42%) hospitals were smoke free in their premises, three (25%) were smoke free indoors and four (33%) had indoor separated smoking area. After implementation, 10 to fifteen (67%) hospitals became smoke free in their premises; and five (33%) were smoke free indoors. Although about half of the hospitals replied that no problem in particular happened, closet smoking and smoking around hospitals remain as challenges.
We reported results of the questionnaire to the surveyed hospitals and could share the information for tobacco control measures of other hospitals. This study contributed to a smooth implementation of the smoking ban of psychiatric hospitals.
