You know how all the smokers switched from analogue cigarettes to new and supposedly healthier digital versions that need batteries and fluids purchasing from the weird shops that are popping up everywhere? Because it's so much healthier? Well, now they say switching from warm smoky air to cold apple-flavoured air isn't all that amazing a change to make, as huffing vapourised chemical compounds gives your lungs an entirely new collection of shit to deal with.
This latest research into the nascent world of vaping suggests that the lungs, when faced with an attack of cinnamon-infused nicotine vapour sucked through the beard-surrounded lips of a modern smoker, may disable some immune cell function; and has the added bonus effect of increasing inflammation. And inflammation is one of today's leading medical blame-carriers for all sorts of additional health woes, with this study suggesting it interferes with the alveolar macrophages in the lungs that pull out dust and infections.
Vapers will be happy to hear this was only the result of a small-scale lab test involving lung tissue samples taken from eight non-smokers, in which the cells were mechanically infused with vaping gases to mimic human use of the e-smoking systems. Study author professor David Thickett says vaping is still clearly better than smoke-smoking thanks to the lack of carcinogens in the vapour, but warns that vapers can still expect to develop COPD if unlucky, explaining: "I don't believe e-cigarettes are more harmful than ordinary cigarettes – but we should have a cautious scepticism that they are as safe as we are being led to believe."
