Notes: Total n and percentages for sample characteristics is based on the 93 participants who completed the participant questions. ¹ Regular use was defined as using an ECIG some days or most days. ² Participants could select more than one option for location where they typically purchased their ECIG liquid. ³ Items from the 4-item E-Cigarette Dependence Scale [19] including “I find myself reaching for my e-cigarette without thinking about it,” I vape more before going into a situation where vaping is not allowed,” “I drop everything to go out and buy e-cigarettes or e-juice,” and “When I haven’t been able to vape for a few hours, the craving gets intolerable.”.
