A study has found that vaping indoors is unlikely to harm bystanders.

The erroneous theory, similar to that of second hand smoking, was obliterated by research conducted by three educational institutions.

The research found that e-cig vapour particles exhaled evaporate in a matter of seconds.

Presented at the fourth Workplace and Indoor Aerosols Conference in Barcelona, the revelation is a heavy blow to e-cig haters.

Interestingly, the research that ventilation systems didn’t alter any of the results.

Dr. Michael Siegel, professor at the Boston University School or Public Health, believes the study is important and the first study to realistically assess 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 at Fontem Ventures, the organisation that spearheaded the research, said that the study validates previous suggestions that e-cigs are safer than tobacco.

A massive win for e-cigs and hugely devastating defeat to retractors, the news is only likely to strengthen the vaping community as more and more smokers are realising the health benefits of e-cigarettes.

Previously, it has been suggested that e-cigarettes may be the greatest invention ever, and are more popular than Jesus.
