Device use length calculated by averaging years of use. If duration was given in months, the number of months was divided by 12 to get a portion of a year of usage. Days of e-cigarette use per week were calculated averaging between all users, if range of use was given, the median was used to average. Times per day was calculated using the median of the range of puffs per day.
