Switch from Smoking to Vaping to Improve Respiratory Health: Study Finds
Advertisement
A new paper in Nicotine and Tobacco Research, published by Oxford University Press, finds that people who switch from smoking cigarettes to vaping see improved respiratory health, but people who begin consuming electronic cigarettes while continuing to smoke regular cigarettes do not report improved respiratory symptoms.
Vaping reduces exposure to toxic chemicals but it has been unclear whether switching from cigarettes to e-cigarettes results in a reduction of the respiratory problems—like wheezing and coughing—common in regular cigarette smokers. Researchers here used data from the Population Assessment of Tobacco and Health (PATH) study, a national longitudinal measure of tobacco use in the United States performed by the National Institutes of Health. The investigators here observed adult participants between 2013 and 2019 who reported smoking cigarettes exclusively at the beginning of the investigation and reported a baseline cough or wheeze.
The researchers divided the subjects 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.
