Objectives: To present the bases for health education on electronic cigarettes, we analyze the present state of electronic cigarettes. Methods: We applied descriptive study, reviewing the literature from domestic and foreign electronic databases such as National Discovery for Science Leaders and PubMed. Results: Electronic cigarette has been the subject of much controversy but very little study. I reviewed and summed up the definitions, device safety, health risk, smoking cessation effects, addiction, second hand smoke, and regulations of electronic cigarettes. Conclusion: Finally,I presented the evidence-based contents and desirable direction for health education about electronic cigarettes. The results suggested that the health educators focus on the potential addiction to electronic cigarettes, instead of the cessation effects.
