Vaping may lead to fewer respiratory infections for ex-smokers


According to a study led by QueenMary University of London (QMUL) the majority of participants who switched from Smoking to vaping say they have fewer repertory infections.

The on-line survey of 941 respondents assessed subjective changes in respiratory symptoms in smokers who had switched to vaping for two months or longer.  The survey showed that 66 per cent of respondents reported an improvement in respiratory functions. 29 per cent reported showed no change and 5 percent reported there symptoms got worse.

Senior author Professor Peter Hajek from QMUL said: “There is no doubt that e-cigarettes are much safer than conventional cigarettes, but smokers are still led to believe that they’re dangerous. This misinformation includes a misreported study on rats that claimed that vaping may increase vulnerability to infections. These new findings from human vapers show that this is not the case.

“The study needs to be interpreted with caution because it is based on self-reported data, and further studies using objective measures are needed. However, the present results provide sufficient information to suggest that vaping does not increase infection rates and may in fact lead to a decrease in infections.”

Previous animal and cell studies have come to the conclusion that vaping may increase vulnerability to infection, but these studies did not use realistic exposure levels. Human tests have reported no significant adverse respiratory damage or effects associated with using e-cigarettes for up to 1.5 years. A follow up study of smokers with asthma who switched to vaping found significant improvements.

The surveyors say that it is obvious that the respondents noticed improvements in their respiratory functions.  This is because smoking cigarettes harms nearly every organ in your body, causes many diseases, and can reduce your life expectancy dramatically.  Cigarette smoking is the leading preventable cause of death in the United States.  Smoking causes more deaths then alcohol use, illegal drug use, and motor vehicle injuries combined.  Smokers are more likely to develop heart disease, stroke, and lung cancer than those who don’t smoke.  There are strong correlations between smoking and cardiovascular disease, respiratory disease, and cancer.

The main limitation to the study is that it is an online survey and the reports are subjective.  Future studies need to assess the overall health and respiratory symptoms of vapors and create a larger sample size. Despite the limitations the researchers say that the study provides positive evidence that vaping is safer then smoking.

Many people look at vaping and smoking cigarettes as picking the lesser of two evils. Both have been shown to have negative side effects to your health but Vaping in our opinion is a much safer and healthier option.
