Is Second-Hand Vaping Harmful?
Anti-smoking activists have slammed vapes and e-cigarettes as more of the same vice under a different marketing gimmick. But does their assertion hold water?

The number one gripe among critics and lawmakers regarding e-cigarettes and vapes is public health; to many in the anti-Big Tobacco crusade, cigalikes and APVs are little more than aesthetically modernized cigarettes. But while smoking alarmists are justified in opposing the leading cause of preventable deaths in the United States, it’s important not to conflate electronic vaporizers with combustible tar-and-tobacco cigarettes. But, YES vaping is also not good for your health.

Conventional cigarettes burn tobacco leaves, benzene and a cellulose acetate (more commonly known as plastic) filter to deliver their “hit” of nicotene. E-cigs and APVs vaporize e-liquids made from the food additives vegetable glycerine and propylene glycol, with nicotene and flavoring thrown in. This major difference in product composition is why second-hand vapor contains less volatile organic compounds than indoor air or exhaled breath. It’s also why second-hand vapor doesn’t endanger bystanders with toxic combustion byproducts.

Studies Speak Louder

Vape proponents claim the assertion that second-hand vapor could be anywhere near as harmful as second-hand smoke is rash at best, and they have research backing their position.

In 2013, Polish scientists Jan Czogala, Maciej L. Goniewicz and Andrzej Sobczak worked in collaboration with the Roswell Park Cancer Institute to study secondhand exposure to vapors from e-cigarettes. Measuring nicotine, volatile organic compounds, aerosol particles and carbon monoxide emissions, they found only minor exposure to nicotine at a level ten times lower than that of combustible cigarettes.

In a 2014 crowd-funded study titled Peering Through the Mist, Drexel University’s Igor Burstyn conducted a systematic literature review spanning 9,000 observations on e-cigarette vapor. Burstyn concluded that there is no evidence vaping produces inhalable exposures to contaminants that warrant health concerns for vapers, and that exposures for bystanders “are likely to be orders of magnitude less, and thus pose no apparent concern.”

An expert independent evidence review published in 2015 by Public Health England found that half the UK population don’t realize e-cigarettes are up to 95% less harmful than smoking, and that there is β€œno evidence of known toxicants in second-hand vapor at levels that would harm bystanders.”

This complements a 2016 report titled Nicotene Without Smoke by the Tobacco Advisory Group of the Royal College of Physicians; a report intended to “provide an update on harm reduction in tobacco smoking in relation to all non-tobacco nicotene products.” In it, the Tobacco Advisory Group concluded that there is no direct evidence passive exposure is likely to cause significant harm–and that “nicotine from exhaled vapor can be deposited on surfaces, but at such low levels that there is no plausible mechanism by which such deposits could enter the body at doses that would cause physical harm.”

Vaping is not Smoking

While some e-cigarettes might look a lot like conventional cigarettes, that is fortunately where the similarity ends. Around the world vaping is steadily being vindicated by medical and scientific research, and with time will likely be recognized as a benefit rather than a danger to society.
