5 year longitudinal study finds e-cigs and cigs have similar risks for respiratory disease and COPD; dual use is worse.Song B, et al. Impact of electronic cigarette usage on the onset of respiratory symptoms and COPD among Chinese adults. Sci Rep. 2024 Mar 7;14(1):5598. doi: 10.1038/s41598-024-56368-9.

“During the 5-year follow-up period, 1071 incident cases of respiratory symptoms and 146 incident cases of COPD were identified in this cohort study. After adjusting for relevant confounding factors, EC users demonstrated a respective increase in the risk of reporting respiratory symptoms and COPD by 28% and 8%. Furthermore, dual users who used both ECs and combustible cigarettes exhibited an elevated risk of incident respiratory symptoms and COPD by 41% and 18%, respectively, compared to those who had never used, non-users of any cigarette products.”
“The aerosol from ECs, unlike combusted tobacco smoke, has been found to increase the risk of cell death and DNA damage while suppressing genes involved in immune function. According to the biological evidence, our study findings demonstrate that the use of ECs independently contributes to an increased risk of respiratory symptoms and COPD. ”
