Almost everybody has heard of ‘passive smoking’ – where innocent bystanders ingest the harmful effects of other peoples’ cigarettes – but what about ‘passive vaping’?


Passive Vaping Studies


The jury is still out on this small controversy, spurred on in no small way by the World Health Organisation who insist that there is not enough evidence available to convince them that electronic cigarettes help people to quit smoking. While essentially harmless, they maintain, there is still the potential threat of nicotine vapour unintentionally being inhaled by passers-by. This is one of the reasons the UK has banned the sale of e-cigarettes to under-18s. The World Health Organisation says e-cigarette aerosol is more than just water vapour and the use of ecigs “poses threats to adolescents and foetuses of pregnant mothers using these devices.”

To date, several studies have been conducted by independent researchers – such as Inhalation Toxicology – as a way of discovering just how much exhaled vapour affects the air around it. Research published in Inhalation Toxicology (a peer-reviewed medial journal) compared the pollutant concentrations present in cigarette smoke with e-liquid vapour. Results so far show that passive vaping is not dangerous to bystanders. In fact, after comparing the pollutants present in tobacco smoke to e-liquid vapour, Inhalation Toxicology discovered that e-liquid vapour posed no significant danger to human health when inhaled indirectly.

The facts are continually coming in and tipping the balance in the favour of e-cigarettes over tobacco cigarettes. Despite the findings of the researchers, there persists a kind of prejudice against vaping: it looks like smoking and so therefore must have some of the harmful effects of smoking. Time – and perennially healthy vapers – will tell.
