E-Cigarettes damage immune cells in the lungs, according to Science Daily. The vapor that these cigarettes produce impairs the activity of alveolar macrophages, which consume and remove dust particles, bacteria, and allergens that have evaded the other mechanical defences of the respiratory tract.
These findings made the researchers suggest that while they need further research to better understand the long term health impact of vaping on people, e-cigarettes may be more harmful than we think, and some of the effects were similar to those seen in regular smokers and people with chronic lung disease.
Vaping is increasing in popularity, but most of the current body of research has focused on the chemical composition of e-cigarette liquid before it is vaped. With the plan to find out what impact they might have, the researchers created a mechanical procedure to mimic vaping and produce condensate from the vapour.
They extracted alveolar macrophages from lung tissue samples provided by 8 non-smokers who had never had asthma or chronic obstructive pulmonary disease (COPD). A third of the cells were exposed to plain e-cigarette fluid, a third to different strengths of the artificially vaped condensate with and without nicotineand a third to nothing for 24 hours.
The results showed that the condensate was significantly more harmful to the cells than e-cigarette fluid and that these effects worsened as the dose increased. After 24 hours of exposure the total number of viable cells exposed to the vaped condensate was significantly reduced compared to the untreated cells, which shows just how dangerous vaping really is.
