Cigarettes can look harmless enough but when they burn they release a cocktail of about 4,000 chemical. 80 of these chemicals have been found to be cancer-causing, such as tar - one of the more well known chemicals found in cigarettes - or Polonium-210.
Tar is a collection of solid particles that are inhaled when a cigarette is lit. When it settles it forms a sticky brown residue that can stain smokers' teeth, fingers and lungs. Though tar is the most well known it is not the most damaging chemical in cigarettes; the most dangerous chemicals in tobacco smoke are present as gases. Polonium-210 is one of these. Tobacco smoke contains traces of polonium, which become deposited inside the airways and delivers alpha-radiation directly to surrounding cells. The lungs of smokers can be exposed to four times more polonium than those of non-smokers and specific parts may get a hundred times more radiation. One study estimated that someone smoking one and half packs a day receives the equivalent amount of radiation as someone having 300 chest X-rays a year.
A full list of cancer-causing chemicals in cigarettes can be found on: info.cancerresearchuk.org/healthyliving/smokingandtobacco/wh As well as the 80 cancer-causing chemicals, cigarettes contain hundreds of poisons such as Hydrogen cyanide. This chemical does the most damage to the heart and blood vessels out of all the chemicals found in cigarettes and though it does not directly cause cancer it significantly increases the risk of other chemicals causing cancer by damaging cilia, lining the airways. Another poisonous chemical found in cigarettes is Toluene which damages brain cells and interferes with their development.
There are also around 599 additives in cigarettes of which Nicotine is one. Nicotine is a highly addictive drug and many additives designed to make cigarettes taste nicer also keep smokers hooked.
There are many hundreds of dangerous chemicals in tobacco smoke but the three that make up the majority of the smoke that is inhaled are tar, carbon monoxide and nicotine.
Tar is a black sticky residue that coats the inside of the lungs. It contains many different chemicals, some of which are carcinogenic and these stick to the surface of the inside of the lungs for long periods of time. They damage the underlying cells, sometimes causing changes that cause the cells to start dividing out of control.
Carbon monoxide is toxic because it binds with proteins inside red blood cells that normally carry oxygen. The carbon monoxide prevents normal oxygen uptake to the blood, which can starve the brain of oxygen.
Nicotine is the chemical in tobacco smoke that reacts with receptors in the brain, giving the smoker the sensation of pleasure that is so addictive. Nicotine is the chemical that keeps smokers smoking.
Tobacco smoke is a mixture of gases and small particles made up of water, tar and nicotine. The tar is a messy mixture of hundreds of toxic chemicals, many of which are known to cause cancer (for example, nitrosamines, benzpyrene). Many of the gases in tobacco smoke are harmful. These include carbon monoxide, nitrogen oxides, hydrogen cyanide, ammonia, and other toxic irritants such as acrolein and formaldehyde. Due to the high temperatures (over 800°C or 1400°F), the burning end of a cigarette is like a miniature chemical factory. It churns out many more noxious chemicals than are found in unlit tobacco or taken in by use of smokeless tobacco (for example, snuff, which contains no tar or gases). Altogether more than 4,000 chemical compounds have been identified in tobacco smoke. However, the other negative effects from smoking are reversed within 24 hours of stopping, when nicotine and carbon monoxide have cleared from the body. So it's never too late to give up!
There are over 4000 chemicals present in cigarettes. Around 50 of these chemicals are known to be carcinogenic that is those chemicals that can cause cancer. A few of the carcinogens present are arsenic, benzene, cadmium, chromium, nickel and urethane. The rest of the chemicals are mostly toxic or poisonous for instance Ammonia and Carbon monoxide respectively.
The four most dangerous chemicals present in cigarettes are nicotine, carbon monoxide, tar and phenol. The addictive nature of cigarette is because of nicotine present in it. Nicotine gives a feeling of pleasure and relief but these are short-term feelings. Nicotine increases the heart rate and blood pressure. Carbon monoxide reduces the circulation of oxygen in the blood and transfers less oxygen to your body organs. Tar causes lungs cancer because it forms a thick coating in your lungs. Phenol is an organic compound and also causes lung cancer.
There is like over 4000 chemicals in a cigarette. So don't smoke it is not good for you or anyone that is around you. The smoke lingers to your clothing and gives you all sorts of cancers and diseases.
There are over 4,000 chemicals in cigarettes. One of the main ones is tar. Tar is a dark sticky substance that forms as a cigarette burns. As this gets inhaled it settles on all the organs of the Respiratory system. Cilia gets clumped together from tar and reduces mucus and then less oxygen gets to your blood cells. This could cause severe heart and lung damage. There is also carbon monoxide that gets dissolved by red blood cells. The cells therefore dissolve the smoke instead of the oxygen causing severe damage to the organs. And then theres nicotine the stuff that gets you addicted to the cigarettes and also causes damage in the body.
Tobacco smoke is dengerous chemicals are harmfull for all humans. Carbon monoxide used by toxi. Protins cells that normally our brain take not a oxygen by tobacco.
