Has anyone seen the recent articles about e-cigarettes linked to lung disease? There is also a current class action lawsuit in progress, since some of the companies promoted e cigarettes as a safe alternative to smoking. I just wanted to make sure others knew in case you were looking at e-cigarette as a method of quitting the habit. The Wall Street Journal published a full profile that main e-cigarette ingredients are tied to "popcorn lung" cell growth and polyps. In short, it's best not to inhale foreign substances if you can help it. Hopefully this can help others make informed decisions about quitting. I know it's easier said than done.
