Still Smoking? Watch This
There is a common misconception that the tar in cigarettes is equivalent to the tar used on roads. As a result of this, cigarette companies in the United States, when prompted to give tar/nicotine ratings for cigarettes, usually use “tar”, in quotation marks, to indicate that it is not the road surface component. Tar is occasionally referred to as an acronym for (Total Aerosol Residue), a backronym coined in the mid-1960s.
The European Union currently limits the tar yield of cigarettes to 10 mg.
Tar when in the lungs coats the cilia causing them to stop working and eventually die, causing such conditions as lung cancer as the toxic particles in tobacco smoke are no longer trapped by the cilia but enter the alveoli directly.
This is really an eye opener of the damage we do do ourselves when smoking.
