Abstract
OBJECTIVES: We examined channels through which information about e-cigarettes has flowed, public perception of e-cigarettes as an innovation, and how these may influence use. METHODS: An online survey of US adults aged 18-24 years (N = 874) was used. Measures included information channels, perception of e-cigarettes as an innovation, and intention to use. RESULTS: Television ranked first for exposure to e-cigarette information. The most positive innovation attributes were observability and relative advantage. A structural model showed that information exposure and favorable perception as an innovation predicted use. CONCLUSIONS: The high degree of e-cigarette awareness combined with depiction of the devices as a favorable innovation may contribute to their wider adoption and may argue for regulation of e-cigarette advertising.
