| Abstract: |
Many patients with cancer use electronic cigarettes (e-cigarettes), yet little is known about patterns and reasons for use. Using cross-sectional baseline data from a randomized controlled trial, we aimed to describe prevalence and correlates of e-cigarette use, frequency of use, and reasons for use among smokers recently diagnosed with cancer. Participants (n = 302) included adults (age ≥18 years) recently diagnosed with varied cancer types who smoked ≥1 cigarette within the past 30-d from two US academic medical centers. Participants reported ever and current e-cigarette use, and current e-cigarette users reported days of e-cigarette use and the main reason for use. We compared current, former, and never e-cigarette users by sociodemographics, cancer type, medical comorbidities, smoking behaviors, attitudes, and emotional symptoms, and described use among current e-cigarette users. Of smokers recently diagnosed with cancer, 49% (n = 149) reported ever e-cigarette use and 19% (n = 56) reported current use. Of current e-cigarette users, 29% (n = 16) reported daily use. Current e-cigarette users did not differ from former and never e-cigarette users by cancer type, smoking behaviors, or emotional symptoms. Women were more likely to be current users than never users, and current e-cigarette users had less education than former users. Most current e-cigarette users reported using them to help quit smoking (75%). One in five smokers with cancer report current e-cigarette use, but most are not using e-cigarettes daily. The majority report using e-cigarettes to quit smoking. E-cigarette use by patients with cancer appears to reflect a desire to quit smoking. © 2018 The Authors.
