E-cigarettes could be just as harmful as tobacco, johns hopkins researchers say

Since their introduction in 2007, many people have seen electronic cigarettes as the safe alternative to smoking. But researchers learned they could be just as harmful to the immune system as tobacco.
A study recently released by the Johns Hopkins Bloomberg School of Public Health compares e cigarettes to regular cigarettes and concludes, “E cigarettes compromise the immune system in the lungs and generate some of the same potentially dangerous chemicals found in traditional nicotine cigarettes.”
To study e cigarette effects, researchers divided mice into two groups one exposed to e cigarette vapor in amounts that were about the same as humans’ e cigarette inhalation for two weeks. The other group was just exposed to air.
Researchers said the mice exposed to the vapor were “significantly more likely to develop compromised immune responses to when exposed to nasal drops of the flu virus and the bacterium responsible for pneumonia and sinusitis, which in some cases killed the mice.”
The complete findings of the study were published in the journal PLOS ONE.
“Our findings suggest that e cigarettes are not neutral in terms of the effects on the lungs,” said senior author Shyam Biswal, a professor in the Department of Environmental Health Sciences at the Bloomberg School. “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 patients who have switched from cigarettes to e cigarettes, or to new users of e cigarettes who may have never used cigarettes.”
Many states have advocated to seek tighter controls against e cigarettes, with some saying they should be regulated like tobacco.
A separate study by the California Department of Public Health in 2013 found e cigarettes emit cancer causing chemicals and get users hooked on nicotine. Read about the full Johns Hopkins study.
