The popularity of e-cigarette is growing worldwide. Its health hazards and role in smoking cessation is controversial. There is no doubt that health care professionals can play a vital role in assisting patients who wish to use e-cigarettes to quit smoking but there is a gap in the evidence. The present study aimed to reveal the perception of e-cigarettes as a quit smoking tool and its health hazards among physicians in Bangladesh. A cross-sectional study was conducted by means of a survey via self-administered structured questionnaires in Bangladesh. Data was collected from September 2019 to February 2020 and analysed by descriptive frequency and chi-square test using SPSS. A total of 145 physicians have participated in this study, 88.9% provided professional advice on quit smoking to their patients. Total 51.7%, 51.9%, 41.3%, 52.4%, 42.8%, and 47.6% physicians mentioned that e-cigarettes may cause throat irritations, cough, headache, dryness of mouth, cardiovascular disease, and cancer respectively. Chi-square test revealed that there is no association between a physician’s professional advice for quit smoking and perception of e-cigarettes as a smoking cessation tool. The physician’s perception of e-cigarettes is crucial for reducing any type of tobacco consumption. Evidence based e-cigarette related public health intervention for physicians are required to mitigate the use of e-cigarette to quit smoking.
