Bystanders are unlikely to be harmed by indoor vaping, a revealing study has found. There have been suggestions that bystanders may be subjected to second-hand vaping. Contrary to some reports, particles emitted via e-cigs evaporate in a matter of seconds, says the research. The research, which serves as a heavy blow to anti-vaping campaigners, was presented at the 4th Workplace and Infdoor Aerosols conference in Barcelona. The results were not affected by the implementation of a ventilation system, further emphasising the safety of vaping. Dr. Michael Siegel, professor at the Boston University School or Public Health, describes the research as important and says it’s the first study to properly assess the effects second-hand vapour. “The important finding is that although exhaled e-cigarette aerosol does contain a high concentration of particulates, the aerosol dissipates within seconds, resulting in aerosol levels dropping to background levels.” “This means that the particulate matter does not accumulate, unlike tobacco smoke, which we know lingers in the air causing the concentration to build up over time.” “The importance of this is that a non-vaper’s exposure to the aerosol particles appears to be fleeting, lasting only a few seconds per puff of the vaper. This study adds to the evidence that vaping poses minimal risks to exposed bystanders.” Marc Michelsen, Senior Vice President of Corporate Affairs and Communications of the organisation behind the research, Fontem Ventures, said the findings support claims that e-cigarettes are 95% safer than regular tobacco. The e-cigarette industry and vaping culture only appears to be going from strength to strength as they are continuously backed up by scientific studies. A study recently found that e-cigs produce no toxins.
