The findings showed that further research is needed to help better understand the long-term health impact of vaping on people, as some of the effects were similar to those seen in regular smoker and people with chronic lung disease.
In an accompanying podcast, Professor Thickett said the tobacco giants, who have bought up numerous e-cigarette companies, have an agenda to portray e-cigarettes as safe.
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 nicotine and a third to nothing for 24 hours.The condensate was found to be more harmful to the cells than plain e-cigarette fluid.
The concern is that long-term vaping might lead to breathing problems.
Previous studies have focused mainly on the chemicals that contain the electronic cigarette fluid before steam, but the new study focuses on steam itself.
With that said, it's no doubt that e-cigarettes are less harmful than traditional cigarettes but the results of the research are undeniable and rather concerning.
Vaping or smoking e-cigarettes has been found to be a harmful practice.
The researchers also noted that when macrophages were exposed to doses too low to kill, the cells spewed out 50-fold higher amounts of oxygen-free radicals, the "rust" of the biological world, compared to unexposed cells.
Moreover, cells exposed to vaped fluid were unable to fight off bacteria. These signals disabled the protective cells in the lungs. "They can act as scavengers that present these particles to the immune system to activate an immune response". "And that may cause a loss of long function at a more accelerated pattern because they're starting it in their teens". 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. A large number of e-cigarette companies are being bought up by tobacco companies and there's certainly an agenda to portray e-cigarettes as safe.
This is a "caution against the widely held opinion" that vaping can be used to aid in giving up cigarettes, the researcher said.
Britton said: "This indicates that long-term use of electronic cigarettes is likely to have adverse effects, as is widely recognised by leading health authorities in the United Kingdom including the Royal College of Physicians and Public Health England". "When the field was originally thinking of these as cessation devices, then some toxicity could be tolerated", he added.
