Vapors of e-cigarettes linked to repressing immune system

e-Cigarette
Claiming to be safer than regular cigarettes, the electronic cigarettes have registered sales as high as $2 billion per year since 2007, but high sales do not translate into genuine healthy alternative.

Thomas Sussan from Johns Hopkins Bloomberg School of Public Health conducted a study that showed how mice exposed to e-cig vapor had weaker immune systems compared to mice who did not.

The paper was published in PLOS ONE.

“Our findings suggest that e-cigarettes are not neutral in terms of the effects on the lungs,” said Shyam Biswal, senior author of the article. “We have observed that they increase the susceptibility to respiratory infections in the mouse models. This warrants further study in susceptible individuals, such as COPD [chronic obstructive pulmonary disease] patients who have switched from cigarettes to e-cigarettes or to new users of e-cigarettes who may have never used cigarettes.”

In the study, researchers organized the mice into two groups. The first group was exposed to vapor from Njoy e-cig for two weeks, while the second group inhaled only fresh air. The mice who were exposed to vapors were placed in an environment that mimicked the dose a human would receive using the e-cig for the period involved. Researchers created subgroups in each vapor and fresh air groups. A subgroup was exposed to Influenza A, and the second was exposed to pneumonia-causing bacteria Streptococcus pneumonia. The third subgroup was not exposed to any additional viruses.

An excess of 400 toxins are usually found in a traditional cigarette, and 60 of these are known to cause cancer. E-cigarette, instead of burning tobacco and releasing the smoke filled with toxins, produces an aerosol filled with nicotine that users will inhale. Even though lack of burning prevents the release of some chemicals, a large number of substances and chemicals are still inhaled, altering the DNA and creating conditions for the development of cancer.

“We were surprised by how high that number was, considering that e-cigarettes do not produce combustion products,” Sussan summarized. “Granted, it’s 100 times lower than cigarette smoke, but it’s still a high number of free radicals that can potentially damage cells.”

    “Granted, it’s 100 times lower than cigarette smoke, but it’s still a high number of free radicals that can potentially damage cells.”

    E-cigarettes are much safer then cigarettes but there’s too much money involved
    in the industry, did you know that In fiscal year 2014, states collected
    $25.7 billion from tobacco taxes and legal settlements, but states spent only
    1.9% of the $25.7 billion on prevention and cessation programs.

    Cigarette smoking causes cancer, heart disease, stroke, lung diseases (including emphysema, bronchitis,
    and chronic airway obstruction), and diabetes.
    For every person who dies from a smoking-related disease, about 30 more people suffer with at least one serious
    illness from smoking.
    More than 16 million Americans suffer from a disease caused by smoking.

    Each day, more than 3,200 persons younger than 18 years of age smoke their first cigarette.Each day, an estimated 2,100 youth and young adults who have been occasional smokers become daily cigarette smokers.
