A good friend of mine has had some heart issues in the last couple years, not from smoking, but this is a reassuring article I can show him to get him to make the switch to eCigs! Great article to give everyone peace of mind that they can vape without worry of heart disease! Thanks for sharing.
Edit: My favorite part of this article - "Previous studies have found that the electronic devices would have to be smoked daily for four to 12 months to achieve the levels of nitrosamines, a carcinogen, that are present in a single tobacco cigarette, the researchers said."
