Researchers at San Diego State University had an ambitious agenda. They wanted to understand why incidents of childhood respiratory conditions like asthma is so prevalent. To that end, they set out on a massive study to research which particulates are polluting the air in our homes. This study was not about second hand vapor. Nonetheless, the results of the study were surprising to some because researchers found that second hand vapor is essentially harmless.
The San Diego State University indoor air pollutant study constantly monitored the air in 300 households. A variety of households were chosen including homes with smokers, vapers etc. Monitors scanned the air for particulates that are between 0.5 and 2.5 micrometers. That size range includes dust, fungal spores, combustion byproducts and vehicle emissions. This size range is relates directly to human health because this size of particulate can penetrate deeply into the lungs. Once penetrating deeply these particulates can have an impact on health causing breathing and cardiovascular problems.
Indoor Pollutants Don’t Include E-Cig Vapor
While second hand vapor may have been shown to not be an indoor air pollutant, many other pollutants were identified. The number one harmful pollutant in a smoker’s home is, no surprise, second hand smoke. In fact, in homes where there is a smoker, the number of pollutants is double that of a home where there is no smoking. While vaping around children is something we should be wary of it is smoking in a home where children live that is downright dangerous.
Surprisingly, combustion particulates from marijuana were as prevalent as particulates from cigarette smoke. The next largest contributors to indoor air pollution were incense, candles, frying food in oil and cleaning products.
Of course the most interesting aspect of this study for vapers is the fact that the SDSU researchers reported the following finding:
“We observed no apparent difference in the weekly mean particle distribution between 43 homes reporting any electronic cigarette usage and those reporting none.”
So that means that electronic cigarettes do not appear to influence the presence of damaging particulates in indoor air. Of course this aspect of the research is not being widely reported. Why? Because, let’s face it, there is an anti-vaping agenda that wants to suppress widespread dissemination of positive news about vaping. This is not the first study to show that second hand vapor does not leave much of a trace. But it is yet another study adding to the always growing body of evidence showing vaping as a potential harm reducer.
“We observed no apparent difference in the weekly mean particle distribution between 43 homes reporting any electronic cigarette usage and those reporting none.” That’s what the researchers said and we think it speaks volumes.
