Background: Vaping is increasingly prevalent among young adults, including student nurses, despite awareness of its health risks. Aims: This study aimed to determine the factors influencing vaping practices among student nurses in a private college. Study design: Descriptive-correlational. Place and Duration of Study:The study was conducted in a privately owned tertiary institution in Iloilo City during the academic year 2025–2026. Methodology: A descriptive-correlational design was used with 317 respondents selected through stratified random sampling. Data were collected using a validated questionnaire and analyzed using descriptive statistics and Spearman’s rho. Results: Respondents demonstrated a moderate level of vaping practices. No significant relationships were found between vaping practices and family support, peer influence, or attitudes toward vaping (p > 0.05). Conclusion: Vaping practices among student nurses are not significantly influenced by family support, peer influence, or attitudes toward vaping, suggesting that other factors such as stress or environmental influences may play a role.
