 The popularity of vaping among university students is increasing due to the development of their lifestyles, the availability of unique flavors, and the potential to reduce dependence on traditional cigarettes. Students are also attracted to vaping due to its convenience and portability, which makes it easier to use while outdoors or at home. Despite these benefits, there is still limited understanding of the long-term effects of vaping on health. To address this issue, this study examined the behavior of four students from the University of Jember and how it affects their health. The findings suggest that the student's decision to vape is influenced by lack of knowledge regarding the potential risks associated with vaping, negative attitudes toward cigarettes, and personal references such as friends and YouTubers. As a result, the students will continue to vape despite the potential health risks. This article was authored by Ovi Triariani, Muri Ririanti, and Ikanafi Kedini.
