Amusing isn't it? People will whine about cigarettes, but happily eat smoked food.
Pro tip; It isn't the tobacco in cigarettes that's bad for you(barring the flue cured varieties). It's the smoke. That also applies to smoked food, smoked whisky, and anything else prepared over fire.
Sounds like bullshit to me. I'm not inhaling food into my lungs, and I also don't smoke a pack of ribs per day.
