I am NOT asking about tobacco cigarettes that contain over 4000 chemicals(at least 40 of which are known carcinogens). I am talking about electronic cigarettes (e-cigarettes).
Electronic cigarettes are devices described as a “healthier alternative” to smoking. They contain no tobacco and therefore none of the harmful chemicals and no tar. They do not burn either so you don’t have to worry about the burning paper or glue. They produce a vapor instead of smoke. The vapor contains nicotine, water, propylene glycol and flavorings.
