A recently published vaping study by scientists at San Diego State University (SDSU) documents the alleged toxicity of second-hand vapor from e-cigarettes. The researchers compared their data to similar statistics derived from the noxious smoke from tobacco cigarettes. An expert in the field of environmental sciences by the name of Neil Klepeis led the research along with his teammates Melbourne Hovell, an expert in behavior health issues, and Suzanne Hughes who acted as co-investigator.
The SDSU team began by soliciting some 300 families from nearby households to partake in the vaping study. Each family had at least one smoker in their ranks and at least one child under 14-years of age. The families then allowed the scientists to place two air particle monitoring systems into the participants’ homes. One was located in the area commonly used for smoking cigarettes, and the second was installed near the child’s bathroom.
Results of the San Diego State vaping study
After carefully placing the air particle monitoring systems into each of the over 300 homes, the research team then regularly scanned the in-home air for very fine particles of such things like fungal spores, bacteria, automobile emissions, dust, and even cooking gases. They were also able to monitor and measure the toxic particles associated with cigarette smoke, which can be as small as 0.5 millimeters in dimension. The length of the vaping study lasted three-months.
What Neil Klepeis and his team discovered includes the following statistics.
- The air quality of homes that allowed indoor cigarette smoking contained twice the quantities of toxic pollution than for households that required smokers to go outside.
- Cigarette smoke was the leading associated cause for the increased toxicity levels.
- Smoking of marijuana was a secondary cause.
- Meanwhile, the team also discovered that some 14.1 percent of participating households allowed indoor vaping but not smoking. However, there were no signs of increased toxicity pollution in the vaping-only homes compared to the homes filled with second-hand smoke. These numbers were also mirrored in the data associated with homes that did not allow vaping or smoking indoors.
The SDSU vaping study Fine particles in homes of predominantly low-income families with children and smokers: Key physical and behavioral determinants to inform indoor-air-quality interventions is readily available per the Public Library of Science (PLOS) website. According to the published report, the data seems to support decades-old research by Dr. Theodore Puck from the 1940s. Pucks research indicates that vaporized propylene glycol (used in e-cigs and vaping e-liquids) is a useful antioxidant against airborne bacteria and other microorganisms suspended in air.
