Asthma can be a very debilitating condition, and as traditional cigarettes can cause inflammation of the respiratory system, it is well-known that smoking can make the condition much worse.
Of course, stopping smoking is easier said than done, despite its negative effects – but now a new study has shed light on compelling evidence that indicates that smokers who suffer from asthma could benefit hugely by switching to e-cigarettes.
The research, published in the Journal of Addiction Research & Therapy, was carried out by Joanna Astrid Miler, Bernhard-Michael Mayer and Peter Hajek of Queen Mary University of London. It involved 941 respondents with asthma switching from cigarettes to e-cigarettes for a period of two months, while reporting any changes in their health or day-to-day life.
When asked by researchers to provide feedback on their experience, two-thirds of all respondents (66%) reported an improvement in respiratory symptoms, while 29% reported no change and only 5% describing their condition as worsened.
E-cigarettes might also improve microbial protection
While further studies are due to take place under more laboratorial conditions, the self-reporting online survey has nonetheless gained the attention of many doctors and scientists since its publication in early August.
This new research has also led to doubts over earlier studies using rats that stated that e-cigarettes could worsen the condition.
“This misinformation includes a misreported study on rats that claimed that vaping may increase vulnerability to infections,”said Professor Peter Hajek.
“These new findings from human vapers show that this is not the case.”
Similar research has also shown that propylene glycol, which is used as a base in many e-liquids, could even improve anti-microbial protection for those who choose to vape.
While the study has limitations due to the use of subjective reports, the authors believe that its results are compelling enough to warrant further research in the field, to dispel myths that e-cigarettes are as damaging as traditional cigarettes.
“There is no doubt that e-cigarettes are much safer than conventional cigarettes, but smokers are still led to believe that they’re dangerous,” said Hajek.
