Flavouring found in e-cigarettes linked to 'popcorn lung'

ConclusionThis study shows three chemicals reportedly linked to serious lung damage are present in many flavoured e-cigarettes in the US, raising concerns about their safety. Although the study tested US brands, it's likely similar findings would be found here in the UK, where e-cigarettes are similarly unregulated.However, this issue is not black and white. The researchers' concerns have been rightly raised, and their conclusion that urgent research needs to follow this study seems logical given the apparent lack of knowledge in this area.  Still, much of the potential health risk and alarm factor of this study hangs on the strength of previous reports suggesting these chemicals can cause lung damage. But this particular study didn't address this directly. We don't yet know whether these chemicals, in their vaporised forms and inhaled at the levels typical in e-cigarettes, cause any lung damage.This study simply looked at how often the three chemicals were detected in e-cigarettes, assuming a link with potential lung damage from other studies that were not appraised here. What we really need is more information on the potential causal link between these chemicals and lung disease, particularly the doses at which any damage might occur, which may or may not be present in e-cigs. Many e-cigarette users may be asking themselves whether they should stop vaping. This study only provides indirect evidence of a risk linking chemicals in e-cigarettes to lung disease, but, if this...
