Smoking to Vaping Switch Improves Respiratory Health

A new study published in Nicotine and Tobacco Research by Oxford University Press reveals that individuals who switch from smoking cigarettes to vaping experience improved respiratory health. However, those who begin using electronic cigarettes while continuing to smoke regular cigarettes do not report any improvement in respiratory symptoms.

Researchers used data from the Population Assessment of Tobacco and Health (PATH) study, a national longitudinal measure of tobacco use in the United States conducted by the National Institutes of Health. They observed adult participants between 2013 and 2019 who reported exclusively smoking cigarettes at the beginning of the investigation and had a baseline cough or wheeze.

The subjects were divided into four groups: those who transitioned from exclusive cigarette smoking to quitting nicotine altogether, those who switched from cigarette smoking to vaping exclusively, those who continued to smoke cigarettes only, and those who kept smoking and also began vaping.

Exclusive E-Cigarette Use Reduces Wheezing, but Not Cough

The study found that completely switching from cigarettes to e-cigarettes led to a moderate increase in the resolution of wheeze symptoms compared to persistent smoking. Among the 5,367 people who reported a baseline wheeze, 2,862 (53%) saw improvements. Switching from cigarettes to e-cigarettes exclusively resulted in significantly reduced wheezing but not cough resolution.

However, lower rates of respiratory symptom resolution were observed among those transitioning to vaping while maintaining or increasing their smoking. Among the 5,210 subjects with a baseline cough, 3,362 (65%) saw their coughs go away.

Dual Use of Cigarettes and E-Cigarettes Shows No Improvement

Transitioning to both smoking and vaping (vs. just continuing to smoke cigarettes) was not associated with respiratory improvement overall or even among participants who reduced their cigarette smoking intensity.

The researchers note that the rates of symptom resolution were 14% lower (for cough) and 15% lower (for wheeze) among those who switched to dual use and maintained or increased their smoking intensity. Those who started using electronic cigarettes while continuing to smoke the same number of regular cigarettes saw their wheeze and coughing worsen.

Quitting Nicotine Altogether Offers Best Improvement

Unsurprisingly, switching from smoking cigarettes to quitting nicotine altogether was associated with the best improvements in both coughs and wheezing.

The study highlights the potential benefits of switching exclusively to e-cigarettes for smokers seeking to improve their respiratory health. However, it also emphasizes the importance of quitting nicotine altogether for the best health outcomes and warns against the dual use of cigarettes and e-cigarettes.
