Carbon Monoxide (CO)
also called carbonous oxide, is a colorless, odorless, and tasteless gas which is slightly lighter than air. It is highly toxic to humans and animals in higher quantities, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions.
Nicotine
is an alkaloid found in the nightshade family of plants (Solanaceae) that constitutes approximately 0.6–3.0% of the dry weight of tobacco, with biosynthesis taking place in the roots and accumulation occurring in the leaves. It functions as an antiherbivore chemical with particular specificity to insects; therefore nicotine was widely used as an insecticide in the past, and currently nicotine analogs such as imidacloprid continue to be widely used. Nicotine is also found in several other members of the Solanaceae family, with small amounts being present in species such as the eggplant and tomato.
Tar
Tar is the common name for the resinous partially combusted and healed particulate matter produced by the burning of tobacco and other plant material in the act of smoking. Tar is purportedly[citation needed] the most destructive component in habitual tobacco smoking, accumulating in the smoker's lungs over time and damaging them through various biochemical and mechanical processes. Tar also damages the mouth by rotting and blackening teeth, damaging gums and blocking papillae and taste buds and the eye's vision.
Tar includes the majority of mutagenic and carcinogenic agents in tobacco smoke (IARC, 1986).[citation needed] Polycyclic aromatic hydrocarbons (PAH), for example, are genotoxic via epoxidation.[citation needed]
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.
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.
Cadium
Cadmium is a substance that can poison the body tissues, especially kidneys.
acrolein
Acrolein is a colorless liquid substances such as aldehydes. This substance is more or less contains high levels of alcohol. That is, acrolein is a liquid alcohol has been taken. This liquid is very detrimental to health.
Hydrogen Cyanide / HCN
Hydrogen cyanide is a gas that is colorless, odorless and tasteless. This substance is the lightest substance, flammable and highly efficient to prevent breathing and damage the respiratory tract. Cyanide is a toxic substance that is very dangerous. Just a little cyanide is inserted directly into the body can lead to death.
I think some kind of toxic substances show above is sufficient to provide an overview of the dangers of smoking. but it all depends on your choice.
