Electronic nicotine delivery systems were promoted publically as a healthier replacement for conventional cigarettes. Knowledge and beliefs of the public can drive their behaviours to adapt or reject the new habit. No previous research was conducted in Jordan to assess electronic cigarettes (e-cigarettes) prevalence, and limited data are available on public opinions and orientation toward this new habit. To assess prevalence of, knowledge, attitude and beliefs about e-cigarettes, and examine factors associated with plans of quitting or initiating e-cigarettes among adults in Jordan. A large cross-sectional face-to-face survey on a random sample of adult population aged ≥ 18 years was conducted over two months to include 1820 adults in Jordan. A representative sample was collected using proportionate random sampling technique, which enabled us to geographically categorise the study population. Reliability and validity measures were taken to ensure a comprehensive and appropriate study tool. The Statistical Package for Social Science (SPSS®) version 24 was used to conduct descriptive analysis, logistic regression, and Rao-Scott chi-square. Findings were considered statistically significant at p value < 0.05 (with a confidence limit at 95%). Of 2164 adults approached, 1820 completed the questionnaire (84.1% response rate). The prevalence of current e-cigarette smokers and dual smokers were 11.7% and 4.0%, respectively. Quitting conventional smoking (38.8%) and enjoying the flavour (32.5%) were the most common reasons to start vaping. Friends were the major source of information about e-cigarettes. There was evidence that adults aged 45-59 years were less likely to be dual smokers (OR 0.51; 95%CI 0.29-0.66; p = 0.03). Poor knowledge about the content (23.7%) and types of e-cigarettes (14.5%) was reported. Plans to reduce or quit e-cigarettes were significantly associated with three factors: smokers' knowledge about its content, social impression, smokers' satisfaction with e-cigarettes. Social impression was also associated with plans of initiating e-cigarettes. Most participants thought vaping cannot be harmful to children and pregnant women (73.1%) and cannot be addictive (58.2%). Electronic cigarettes were considered helpful in smoking cessation by 69.1% of participants. The proportions of adults who were currently electronic cigarette and dual smokers were 11.7% and 4.0%, respectively. Our research may provide insight to product and individual factors that were associated with plans to sustain, quit or initiate electronic smoking.
