Yes. The ratings cannot be used to predict how much tar a smoker will actually get because the way the machine smokes a cigarette is not the way a person smokes a cigarette. A rating of 7 milligrams does not mean that you will get only 7 milligrams of tar. You can get just as much tar from a light cigarette as from a full-flavor cigarette. It all depends on how you smoke. Taking deeper, longer, and more frequent puffs will lead to greater tar exposure. Also, a smoker’s lips or fingers may block the air ventilation holes in the filter, leading to greater tar exposure (7).
