Changes in the Frequency of Airway Infections in Smokers Who Switched To Vaping: Results of an Online Survey

Joanna Astrid Miler*, Bernhard Mayer and Peter Hajek

Background and aim: Cell and animal studies suggested that use of e-cigarettes may increase vulnerability to respiratory infection, though the available studies have serious limitations. Limited data are available on respiratory health of vapers.
Methods: An on-line survey assessed subjective changes in respiratory symptoms in smokers who switched to vaping for at least two months.
Results: Among 941 responders, 29% reported no change in respiratory symptoms, 5% reported worsening, and 66% reported an improvement. Among qualitative comments, 232 elaborated on positive and 15 on negative experiences.
Conclusion: The switch from smoking to vaping was associated with a reduced incidence of self-reported respiratory infections. Further studies using objective measures in samples that are not self-selected are needed.
