This contains Nicotine, Water and propylene glycol. Normal Cigarettes contain 4000 chemicals, so is this a "safe" cigarette? probably not, but is it "SAFER" yes. here's what the fda says about the propylene glycol.

The Food and Drug Administration (FDA) has determined propylene glycol to be "generally recognized as safe" for use in food, cosmetics, and medicines. It is used in food coloring, and flavoring, as an additive to keep food, medicines and cosmetics moist, and in machines that simulate smoke, although usage in simulating smoking devices is not currently included in the list of uses generally recognized as safe by the FDA. In NJOY, propylene glycol functions to provide the vapor mist that looks like smoke and to suspend flavor

Like I said before, I am not looking to quit, I like smoking. My luck, if I quit I would get hit by a bus the next day. I just have this thread because many smokers are stuck out in the cold and this is a way to be able to smoke indoors.
