San Diego State University scientists have determined that there is an "unremarkable" difference in the number of airborne particulate matter in the home of vapers and those who do not vape or smoke.
The SDSU study, published in May, was funded by a grant from the National Heart, Lung, and Blood Institute — one of the National Institutes of Health (NIH). They looked at 300 family homes in San Diego, all of which had at least one smoker and one child under age 14. Particle monitors were installed in two locations within each home. after 3 months of data, the monitors transmitted data to SDSU scientists. they had been continuously scanning the household air for fine particles between 0.5 and 2.5 micrometers.
Particles of this size are small enough to be inhaled deep into the lungs, where they can cause breathing and cardiovascular problems; much like secondhand smoke.
“Our primary goal was to figure out what’s happening in houses that leads to higher air particle levels and, in turn, to unhealthy environments for kids,” says John Bellettiere, one of the co-authors of the study. “We observed no apparent difference in the weekly mean particle distribution between 43 homes reporting any electronic cigarette usage and those reporting none.”
“The aim of our research is, ultimately, to find effective ways to promote smoke-free homes and also to find good strategies, in general, for reducing exposure to household pollution,” said lead author Neil Klepeis. “The findings from our work will allow for better education and feedback to families.”
The study seems to reinforce a feeling many vapers already have; that vaping is significant in the battle for tobacco and smoke harm reduction.
