I know that Newport brand cigarettes contain a considerable amount of fiberglass, which consequently cuts up lung tissue causing more damage than other brands. Some of my smoking buddies, however, seem to think that menthol cigarettes, in general, contain the same damaging agent, causing the smoker’s lungs to bleed a bit every time they smoke them.
Now, I did read that the menthol allows the nicotine to travel through your blood faster (or something of that nature), but how much worse are, say, Marlboro Menthol Lights compared to Marlboro Lights?
