We know about the dangers of smoking and over recent decades have started to realise the effects that passive smoking has too. For a long time secondary smoke was overlooked and not seen as a danger – but we now know that is not the case at all. Now that we’re fully aware of the danger passive smoking causes we have a smoking ban in public areas and smoking around others is much more frowned upon than it once was. The smoking ban was introduced in 2007 but even before that people were vocal about their thoughts on passive smoking. For example Record Breakers star Roy Castle who said he felt his lung cancer was down to playing in smoky clubs and pubs for many years.
There has also been plenty of examples of the damage that breathing in secondary smoke had already done before the UK’s smoking ban was introduced in 2007, with one of the more famous examples being that of Record Breakers star and trumpet player Roy Castle, who attributed his lung cancer on the passive smoking he had been subjected to throughout his many years performing in smoky clubs and pubs.
For many people electronic cigarettes were seen as a healthier alternative to cigarettes, but this led people to wonder whether the vapour could cause problems to people who might passively inhale it.
Passive Vaping – The Research That Has Been Done
Research shows that compared to tobacco cigarettes electronic cigarettes produce very small exposure, which has no human risk. In fact there have been a number of different independent researchers have looked into what changes happen to the air when vapour is exhaled. Studies into this are ongoing, but so far much of the research shows that there is little to no danger. So far all evidence points to the fact that passive vaping isn’t even really a real thing.
Research undertaken by Inhalation Toxicology shows that there is not enough pollutant concentrations present in e liquid vapour to prove a danger. They have also shown that electronic cigarette vapours are not the same as tobacco smoke – they do not have any danger to those that passively inhale them.
Another study held by Fraunhofer Wilhelm-Klauditz-Institute’s Department of Material Analysis and Indoor Chemistry in Germany shows that e cigarette vapour did not contain enough volatile organic compounds (VOCs) to be detectable. They had a volunteer who agreed to smoke both normal cigarettes and an electronic cigarette and exhale into an air chamber, so that the effect of the air could be measured. They looked at the toxins in the air to see how it was effected and they could see that vapour being exhaled did not have a detrimental effect on the air at all.
Even in these small cramped conditions vapour showed no threat to anyone around in the area, which means that in the real world the chances of anyone being in danger by passive vaping is even less.
