One video that you may leave smoking

An experiment of cigarette smoking will cause many types of cancer in our body and the main purpose of this video is to separate the tar contents of the cigarette.
Tar is the common name for the resinous, partially combusted particulate matter produced by the burning of tobacco and other plant material in the act of smoking. Tar is toxic and damages the smoker's lungs over time through various biochemical and mechanical processes. Tar also damages the mouth by rotting and blackening teeth, damaging gums, and desensitizing taste buds. Tar includes the majority of mutagenic and carcinogenic agents in tobacco smoke (IARC, 1986). Polycyclic aromatic hydrocarbons (PAH), for example, are genotoxic via epoxidation.
There is a common misconception that the tar in cigarettes is equivalent to the tar used on roads.[citation needed] 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.
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. Thus, the alveoli cannot come through with the process that is called ‘gas exchange’ which is the cause of rough breathing.

Smoking is a practice in which a substance is burned and the resulting smoke breathed in to be tasted or inhaled. Most commonly the substance is the dried leaves of the tobacco plant which has been rolled into rice paper into a small, round cylinder called a "cigarette". This is primarily practiced as a route of administration for what has come to be termed "recreational drug use" because the combustion of the dried plant leaves releases active substances into the body. In the case of cigarette smoking these substances are contained in a mixture of aerosol particles and gasses and include the pharmacologically active alkaloid nicotine; the vaporization creates heated aerosol and gas to form that allows inhalation and deep penetration into the lungs where absorption into the bloodstream of the active substances occurs. In some cultures, smoking is also carried out as a part of various rituals, where participants use it to help induce trance-like states that, they believe, can lead them to "spiritual enlightenment".
