The biggest harm of ordinary cigarettes is tar, which refers to a layer of brown greasy substance left in the cigarette holder when smoking, commonly known as cigarette oil.

A very intuitive change in the process of smoking is that the color of the filter gradually deepens with smoking, and the fingers with cigarettes will also be smoked and discolored. Of course, the teeth will be dyed dark after smoking, and the fundamental reason is tar.

Tar is not just a color change. In fact, it is the product of incomplete combustion of organic matter under anoxic conditions, so it contains a lot of organic matter, many of which are carcinogens.

For example, carcinogens such as benzopyrene, cadmium, arsenic, β-tea, amines, nitrosamines, and cancer-promoting substances such as phenols and fumaric acid. Because of this, ordinary tobacco has become a carcinogen listed by the International Agency for Research on Cancer under the World Health Organization, which is definitely carcinogenic.

In addition, cigarette tar can also accelerate the aging of human blood vessels, leading to the gradual hardening and loss of elasticity of blood vessels, leading to cardiovascular diseases, while many other diseases are often caused by tar, so the first advice of many disease doctors is to quit smoking.
