This study aims to explore the initiation process and perspectives on e-cigarettes from young adult vapers in China, especially in terms of culture.MethodIn-depth one-on-one personal interviews and focus groups with 47 young adult vapers in China were conducted to understand their e-cigarette usage behavior and cultural understanding. Thematic analysis was employed to identify themes related to their initiation process and the cultural identity of e-cigarette use.ResultThree themes emerged regarding e-cigarette usage behavior among the young adult were identified: (i) e-cigarette initiation process and use pattern, (ii) temporal orientations towards risks and benefits, and (iii) self-construction of individual and relationship. The latter two themes reflect the cultural understanding that young adult vapers hold about e-cigarettes.ConclusionOur qualitative evidence suggests that while single and dual users share a similar initiation process in general, their behavioral structures differ in significant ways in detail. Cultural factors such as time orientation and self-construction are crucial for tailoring health messages and designing interventions aimed at reducing e-cigarette use and addressing addiction among young adult vapers.
