Waterpipe Smoking Among Japanese Teens and Young Adults: an Emerging Public Health Concern

To our knowledge, this is the first study to examine waterpipe smoking among teens and young adults in Japan, the most prevalent age group for waterpipe smokers globally. The reasons cited for use were similar to those in other countries, including peer influence and appealing flavors, with misconceptions about reduced harm and viewing waterpipe use as "cool" being particularly associated with use. Efforts to address misperceptions of reduced harm and social desirability are essential to reducing youth vulnerability. Our findings highlight the need for continued monitoring, targeted education, and policy interventions to tackle this emerging public health concern.
