Just felt like it!

IF YOU SMOKE DONT IGNORE IT, READ IT ....
How do these ingredients harm health?Tobacco-specific nitrosamines (TSNAs) and tar are particularly carcinogenic, while carbon monoxidedecreases the amount of oxygen in your blood. This means your heart has to work harder to pump blood around the body, raising your pulse and blood pressure, and can lead to shortness of breath.As well as being a carcinogen, tar condenses into a brown sticky substance that deposits in the lungs, transporting many other harmful chemicals from smoke in the process. Tar clogs up the small hairs (cilia) that protect and clean the lungs.Nicotine causes addiction, making it difficult to stop smoking and avoid the illnesses it causes. Even when faced with amputation if they don't quit, some smokers cannot give up.Some studies say ammonia makes nicotine more addictive by increasing nicotine vapour in a cigarette to give a bigger 'kick'.The tobacco industry has been accused of adding ammonia to cigarettes, but this is the subject of much disagreement because the natural ammonia content of various tobacco types differs, and ammonia is also a by-product when a cigarette is smoked.
Formaldehyde can cause cancer and damage to your skin, lungs, stomach and bowels.
Hydrogen cyanide is one of the most toxic chemicals in cigarette smoke. It can cause headaches, nausea, dizziness and vomiting.
Benzene can cause cancer, particularly leukaemia.
Lead can cause damage to the brain, kidney and red blood cells.
A lit cigarette is like a chemical factory, releasing poisonous fumes into your lungs and air. Only the tobacco companies know exactly what goes into each cigarette, and only some of this information is available.This means research is still underway to determine exactly what goes into a cigarette. So far more than 4000 different substances have been identified in cigarette smoke. Around half of these substances are found in the tobacco itself, the rest are produced as the tobacco burns.Studies are ongoing to determine which additives and ingredients in tobacco smoke are harmful. For example, health authorities in Canada have produced a list of 44 substances they consider to be particularly harmful:
ammonia
carbon monoxide
nicotine
nitric oxide
hydrogen cyanide
mercury
tar*
toxic trace metals (nickel*, lead, cadmium*, chromium*, arsenic* and selenium)
tobacco-specific nitrosamines (TSNAs): N-nitrosonornicotine*, nicotine-derived nitrosamino ketone (NNK)*, N-nitrosoanatabine* and N-nitrosoanabasine*.
aromatic amines: 1-aminonapthalene, 2-aminonapthalene, 3-aminobiphenyl and 4-aminobiphenyl*
benzo[a]pyrene*
volatile carbonyls (formaldehyde*, acetaldehyde*, acetone, acrolein, propionaldehyde,crotonaldehyde, methyl ethyl ketone and butyraidehyde)
10 selected basic semi-volatiles: pyridine and quinoline
11 phenolic compounds: hydroquinone, resorcinol, catechol, phenol, m+p-cresol, and o-cresol
13 selected volatiles: 1,3-butadiene*, isoprene, acrylonitrile*, benzene*, toluene and styrene.
*carcinogenic (cancer causing)
Smoke harms non-smokersWhile all tobacco smoke is bad for your health, there are two types of smoke.The smoke you inhale is called mainstream smoke, the smoke from the cigarette tip between puffs is called sidestream smoke.Mainstream and sidestream smoke have different chemical compositions: sidestream smoke contains a higher concentration of harmful substances. Almost 85 per cent of smoke in a room comes from sidestream smoke.Because smokers are exposed to both types of smoke, this doesn't mean that passive smoking is more dangerous. But a non-smoker who lives in a smoky environment will have nicotine content in their blood as high as that of a moderate smoker, ie 10 a day.
