Smokers' sources of e-cigarette awareness and risk information

INTRODUCTION Few studies have explored sources of e-cigarette awareness and peoples' e-cigarette information needs, interests or behaviors. This study contributes to both domains of e-cigarette research. METHODS Results are based on a 2014 e-cigarette focused survey of 519 current smokers from a nationally representative research panel. RESULTS Smokers most frequently reported seeing e-cigarettes in stores (86.4%) and used in person (83%). Many (73%) had also heard about e-cigarettes from known users, broadcast media ads (68%), other (print, online) advertisements (71.5%), and/or from the news (60.9%); sources of awareness varied by e-cigarette experience. Most smokers (59.9%) believed e-cigarettes are less harmful than regular cigarettes, a belief attributed to "common sense" (76.4%), the news (39.2%) and advertisements (37.2%). However, 79.5% felt e-cigarette safety information was important. Over one-third said they would turn to a doctor first for e-cigarette safety information, though almost a quarter said they would turn to the Internet or product packaging first. Most (59.6%) ranked doctors as the most trustworthy risk source, and 6.8% had asked a health professional about e-cigarettes. CONCLUSIONS Future research should explore the content of e-cigarette information sources, their potential impact, and ways they might be strengthened or changed through regulatory and/or educational efforts.
