We provide descriptive statistics for the participants' answers, plus statistical comparisons between the short-term (< 12 month) e-cig users (n = 48) and the long-term (1 year or more) e-cig users (n = 56). Standard statistical tests (including chi-squared test for categorical variables, independent t-test for normally distributed variables, and the Mann–Whitney U-test for skewed data) were used to compare those two groups. Statistical analyses were performed with spss version 18 (SPSS Inc. Chicago IL, USA).
