Knowledge Attitude and practice about E-cigarettes among University Students: A comparative study between Afghanistan, Netherlands, and Turkey

Background The rise in electronic cigarette (e-cigarette) use among young adults has raised significant public health concerns. Initially introduced as a harm-reduction tool, e-cigarettes have increasingly become a popular alternative to traditional smoking. However, misconceptions about their safety, social acceptability, and long-term health effects persist among university students. Objective The aim of this study was to find out the knowledge, attitude, and practice about E-Cigarettes among University Students in Afghanistan, the Netherlands, and Turkey. Methods This study adopts an analytical cross-sectional design and employs a foundational approach by administering an online questionnaire. The study uses a quantitative methodology to explore universities students’ knowledge, attitudes, and perceptions regarding e-cigarettes. Data collection was facilitated through a survey distributed via Google Forms and statistical analysis was performed using SPSS 26 to identify significant associations. Results The findings revealed that 54.2% of students reported using e-cigarettes, with a higher prevalence among those with close friends or family members who smoked. Knowledge about e-cigarettes was generally low, with 56.2% demonstrating poor understanding, particularly regarding the health risks and regulatory status of e-cigarettes. Attitudes were largely negative, with 73.4% expressing concerns about vaping, though 62.7% believed it was more socially acceptable than traditional smoking. Peer influence was a major factor, as 74.6% of e-cigarette users had close friends who also vaped. A significant association was found between smoking tobacco and e-cigarette use (p = 0.00), indicating a trend of dual-use rather than e-cigarettes serving as a quitting tool. Conclusion The study highlights a critical gap in e-cigarette knowledge and a strong influence of social and environmental factors on vaping behaviors. Despite negative attitudes toward vaping, its perceived social acceptability remains high. Public health interventions should focus on targeted educational campaigns, peer-led awareness programs, and regulatory measures to address misconceptions and reduce e-cigarette use among young adults.
