Study Linking Nicotine and Heart Disease Suggests E-Cigarettes Not Safe for Heart

A study that shows nicotine contributes to smokers’ higher risk of developing heart disease suggests the nicotine in e-cigarettes is not necessarily safe for the heart, CNN reports.

The study found human and rat heart cells exposed to nicotine showed changes after only six hours. A type of cellular drill formed and ate through tissue. The result was the formation of plaque, which forms in heart disease, the researchers reported this week at the American Society of Cell Biology.

“These findings suggest that e-cigarettes, the battery-powered devices that deliver nicotine in steam without the carcinogenic agents of tobacco smoke, may not significantly reduce smokers’ risk for heart disease,” researcher Chi-Ming Hai, PhD, of Brown University, said in a news release.

Some studies have suggested e-cigarettes may help smokers quit. A study published this week concluded people who use e-cigarettes indoors may be exposing the people around them to nicotine.

    The Surgeon General lies that smoking causes heart disease, by falsely blaming it for heart disease that’s really caused by infections, particularly cytomegalovirus. Smokers, and therefore ex-smokers including vapers, and passive smokers are more likely to have been exposed to these infections for socioeconomic reasons.

    Once again junk science rears its ugly head. Not only did this experiment not study ecigs, it did not take into account the vast amount of epidemiology (real-world science) that shows little or no harm from nicotine. CNN also left out the part where the researcher thought that ecigs might actually be a good tool to quit smoking.
    Your summary left out some other important info:
    Previous studies, such as one published in the journal The Lancet in September, have suggested e-cigarettes may be a more effective way for smokers to quit than nicotine patches or the “cold turkey” method.
    In 2007, the Royal College of Physicians concluded, “If nicotine could be provided in a form that is acceptable and effective as a cigarette substitute, millions of lives could be saved.”
