According to a report by Turkish media NTV on December 26, research predicts that the use of e-cigarettes will exceed that of traditional tobacco in the next few years. A study presented at the American Heart Association's annual meeting found that e-cigarette users who were regularly exposed to nicotine performed worse than non-tobacco users on a treadmill test used to measure heart disease risk. Shows similar harmful health effects to traditional tobacco.
Laboratory studies have also shown that e-cigarettes may be linked to certain types of cancer. According to figures from Action on Smoking and Health, almost one in 20 teenagers aged 11 to 15 in England regularly use e-cigarettes.
Experts worry that some e-cigarettes are designed in part to appeal to teenagers by adding flavors such as blackberry, which could mean a risk of nicotine addiction for a new generation.
