The yellow stains on a smoker’s fingers and teeth is caused by the tar that results from smoking tobacco.
Tar causes great damage to a person’s lungs as it kills the cilia, affecting breathing ability.
The accumulation of this substance can be difficult to imagine, but a graphic video demonstrates for people the levels of tar that is extracted from approximately 20 packs of cigarettes.
Smoking Video Shows Tar Extraction
The video Still Smoking? Watch This! shows an experiment where almost 400 cigarettes are “smoked” through water using a vacuum. The water turns brown and then eventually black as the tar is extracted from the cigarettes. The more “tarry” the water, the more smoke is trapped as well.
The experimenters then boil the tar water. After the water as evaporated, only the thick black tar remains. After letting the substance dry, the result is a sticky, crusty tar crust.
This experiment was done to stimulate what substance settles in a smoker’s lungs.
More Reason to Quit Smoking
The cigarettes used in this experiment contained 18 mg of tar. Cigarette companies manufacture cigarettes in three categories:
- low tar cigarettes with 7 mg of tar or less
- medium tar cigarettes with 15 to 21 mg of tar
- high tar cigarettes with 22 mg of tar or more
Cigarettes contain over 4,00 chemicals, including more than 40 known carcinogens. Tar in cigarettes is the byproduct of smoking tobacco. Tar build up in the lungs causes damage as it prevents proper functioning. The accumulation of tar in a smoker’s body contributes to several health problems, including the following few:
- lung cancer
- chronic respiratory disease
- mouth cancer
- throat cancer.
