Cigarette smoke is a danger poison. Because more than 4000 identified constituents are present in cigarette smoke. So, who is having smoking habit will near with the death. The components of cigarette smoke include nicotine, acetone, methanol, cyanhydric acid, naphtylamine, ammoniac, urethane, toluene, arsenic, pyrene, naphthalene, dibenzacridine, polonium 210, cadmium, carbon monoxide, vinyl chloride, and DDT.
Nicotine which is a toxic alkaloid and accounts for the addictive properties of tobacco, so it is the psychoactive component of tobacco. Inhaled nicotine reaches the brain within 15 seconds and concentrations in brain tissue remain high for about 2 hours. Besides that, it is transformed by oxidation in the liver to conitine which is then excreted in the urine where it can be detected by a laboratory test. In the brain, it activates the dopamine reward system and increases certain neurotranmitters and hormones including norepinephrine, epinephrine , endorphins, and acth/cortisol. Other activators of the dopamine reward system include opiates, amphetamines, and cocaine. Nicotine is 10 times more potent than heroin in its addictive properties, so it is very danger poison on smoke.
In addition, acetone is one part of component smoke. It is a colourless volatile liquid ketone valuable as a solvent of organic compounds, such as paints, and varnishes. Methanol is also a colourless volatile in flammable liquid, usually is used as a solvent or rocket fuel. Besides that, smoke also got component of naphthalene, which is a white crystalline aromatic substance produced by the distillation of coal tar and used in mothballs and the manufacture of dyes.

On the other hand, cadmium is a soft bluish white toxic metallic element occurring naturally with zinc ores, and usually used in the manufacture of solders and pigments and in electroplating or batteries. Moreover, carbon monoxide also is one part of component smoke. It is a colourless odourless toxic gas formed by the incomplete burning of carbon, and it can found in exhaust furnes.
Besides that, DDT is means dichlorodiphenyltrichloroethane. It is a synthetic organic compound used as an insecticide. But now it is widely banned for its damaging effects on wildlife. Arsenic is a highly poisonous white powdery substance used in weedkillers, lethal poison such as rat poison. In addition, polonium-210 is around 250,000 times more toxic than hydrogen cyanide. The main hazard is its intense radioactivity (as an alpha emitter), which makes it very difficult to handle safely.
Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a large, flat aromatic system. Pyrene is a colorless solid. Animal studies have shown pyrene is toxic to the kidneys and the liver. Toluene, also known as methylbenzene or phenylmethane, is a clear, water-insoluble liquid with the typical smell of paint thinners, redolent of the sweet smell of the related compound benzene. It is an aromatic hydrocarbon that is widely used as an industrial feedstock and as a solvent. Like other solvents, toluene is also used as an inhalant drug for its intoxicating properties.
