Abstract
Since 1998, volunteer doctors have provided tobacco prevention classes in Kanazawa, Japan. At the eight-year follow-up, a question naire survey has been conducted on the smoking behaviors of 20-year-old young adults since fiscal year 2010. The smoking rates in the group receiving non-smoking education significantly decreased compared with those in the control group for fiscal years 2014 to 2016. However, the effectiveness of smoking prevention education decreased after fiscal year 2017. Moreover, the so-called new cigarettes, such as heating or electronic ones, suddenly increased in Japan. The study infers that skillful advertising and corporate strategies of cigarette industries are being implemented in the background. Thus, it recognizes the need to target the new forms of cigarettes through non-smoking education inform students about their risks. In addition, because the questionnaire survey at the coming-of-age ceremony is an opportunity for educating new adults about the harm of cigarettes, we expect an improvement in later smoking behavior. Toward this end, the study will continue to administer this questionnaire.
