Default What's in the Cigarette

Pasintabi po sa mga Kabaro nating naninigarilyo.....

A cigarette may look harmless enough - tobacco leaves covered in classic white paper. But when it burns, it releases a dangerous cocktail of about 4,000 chemicals including:

more than 70 cancer-causing chemicals
hundreds of other poisons.
nicotine, a highly addictive drug, and many additives designed to make cigarettes taste nicer and keep smokers hooked.

This page has more information on the various poisons in cigarette smoke. You can also read about where these come from and how concentrated they actually are.
Cancer-causing chemicals in tobacco smoke

Tar - a mixture of dangerous chemicals
Arsenic - used in wood preservatives
Benzene - an industrial solvent, refined from crude oil
Cadmium - used in batteries
Formaldehyde - used in mortuaries and paint manufacturing
Polonium-210 - a highly radioactive element
Chromium - used to manufacture dye, paints and alloys
1,3-Butadiene - used in rubber manufacturing
Polycyclic aromatic hydrocarbons - a group of dangerous DNA-damaging chemicals
Nitrosamines - another group of DNA-damaging chemicals
Acrolein - formerly used as a chemical weapon
Other chemicals

Other poisons in cigarette smoke

Hydrogen cyanide - used as an industrial pesticide
Carbon monoxide - found in car exhausts and used in chemicals manufacturing
Nitrogen oxides - a major component of smog
Ammonia - used to make fertilisers and explosives
More poisons

Tar

Tar is a term that describes a collection of solid particles that smokers inhale when they light a cigarette. It is a mixture of lots of chemicals, many of which can cause cancer. When it settles, tar forms a sticky, brown residue that can stain smokers’ teeth, fingers and lungs.

Because tar is listed on packs, it is easy to believe that it is the only harmful part of cigarettes. But some of the most dangerous chemicals in tobacco smoke are present as gases, and do not count as part of tar. This means that cigarettes with less tar still contain all the other toxic chemicals.

Arsenic

Arsenic is one of the most dangerous chemicals in cigarettes. It can cause cancer as well as damaging the heart and its blood vessels.

Small amounts of arsenic can accumulate in smokers’ bodies and build up to higher concentrations over months and years. As well as any direct effects, it can worsen the effect of other chemicals by interfering with our ability to repair our DNA.

Fish and seafood can be major sources of arsenic, but in a form that is less toxic and more readily removed from the body. In contrast, tobacco smoke contains arsenic in a more dangerous form.

Benzene

Benzene is a solvent used to manufacture other chemicals, including petrol. It is well-established that benzene can cause cancer, particularly leukaemia. It could account for between a tenth and a half of the deaths from leukaemia caused by smoking.

Tobacco smoke contains large amounts of benzene and accounts for a big proportion of our exposure to this poison. The average smoker inhales about ten times more benzene than the average non-smoker.

And some studies have estimated that the amount of benzene that a person inhales through second-hand smoke over their lifetime could increase their risk of cancer.

Cadmium

Cadmium is a metal used mostly to make batteries. The majority of cadmium in our bodies comes from exposure to tobacco smoke. Smokers can have twice as much cadmium in their blood as non-smokers.

Studies have found that the amounts of cadmium present in tobacco smoke are capable of affecting our health. It is a known cause of cancer, and can also damage the kidneys and the linings of the arteries.

Our bodies have proteins that mop up harmful chemicals like cadmium, but the amounts in smoke can overload these proteins. Cadmium can also prevent our cells from repairing damaged DNA. Because of this, it can make the effects of other chemicals even worse.

Formaldehyde

Formaldehyde is a smelly chemical used to kill bacteria, preserve dead bodies and manufacture other chemicals. It is one of the substances in tobacco smoke most likely to cause diseases in our lungs and airways.

Formaldehyde is also a known cause of cancer. It is believed that even the small amounts in second-hand smoke could increase our lifetime risk of cancer.

Tobacco smoke is one of our major sources of formaldehyde exposure. Places where people smoke can have three times the normal levels of this poison.

Polonium-210

Polonium is a rare, radioactive element and polonium-210 is its most common form. Polonium strongly emits a very damaging type of radiation called alpha-radiation that can usually be blocked by thin layers of skin.

But tobacco smoke contains traces of polonium, which become deposited inside their airways and deliver 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.

Chromium

Chromium is a metal used to make metallic alloys, dyes and paints and comes in different types. Chromium III or ‘trivalent chromium’ is most commonly used. It is available as dietary supplements and is harmless.

On the other hand, chromium VI or ‘hexavalent chromium’ is very toxic, is found in tobacco smoke, and is known to cause lung cancer. It allows other cancer-causing chemicals (such as polycyclic aromatic hydrocarbons) to stick more strongly to DNA and damage it.

1,3-Butadiene

1,3-butadiene or BDE is an industrial chemical used in rubber manufacture. Some scientists believe that of all the chemicals in tobacco smoke, BDE may present the greatest overall cancer risk. It may not be as good at causing cancer as some of the other chemicals listed here, but it is found in large amounts in tobacco smoke.

Polycyclic aromatic hydrocarbons

Polycyclic aromatic hydrocarbons or PAHs are a group of powerful cancer-causing chemicals that can damage DNA and set cells down the road to becoming tumours.

One of these chemicals - benzo(a)pyrene or BAP - is one of the most widely studied of all tobacco poisons. BAP directly damages p53, a gene that normally protects our bodies against cancer.

Nitrosamines

Nitrosamines are a group of chemicals that can directly damage DNA, like polycyclic aromatic hydrocarbons (PAHs).

They are found in small amounts in food. But tobacco products, including those that are chewed rather than smoked, are by far our largest source of exposure to these chemicals. Even though they are found in relatively small amounts in cigarettes, they are very strong cancer-causing chemicals.

Acrolein

Acrolein is a gas with an intensely irritating smell and is one of the most abundant chemicals in cigarette smoke. It belongs to the same group of chemicals as formaldehyde and acetaldehyde, both of which can cause cancer.

Until now, it wasn’t clear if acrolein causes cancer as well, but recent experiments suggest that it can. We now know that acrolein can cause DNA damage that is similar to the damage seen in lung cancer patients. Since smoke contains up to 1,000 times more acrolein than other DNA-damaging chemicals, it could be a major cause of lung cancer.

Acrolein also stops our cells from repairing DNA damage, like arsenic and cadmium. And like hydrogen cyanide, it kills the hairs that normally clean our lungs of other toxins.

Other chemicals

Some of the other cancer-causing ingredients of tobacco smoke include:

metals, such as nickel, lead, cobalt and beryllium. While you may be exposed to some of these metals through domestic items or food, inhaling them in tobacco smoke is worse, because they are easily absorbed by the lungs.
acetaldehyde, which is also formed in your tissues when you drink alcohol - it is responsible for many nasty hangover symptoms
hydrazine, a very toxic chemical used mainly in rocket fuel



Hydrogen cyanide

Hydrogen cyanide is a poisonous gas. Of all the chemicals in tobacco smoke, it does the most damage to the heart and blood vessels.

Hydrogen cyanide does not cause cancer, but it increases the risk of other chemicals causing cancer by damaging cilia. These are tiny hairs lining the airways that help to clear toxins away. By killing cilia, hydrogen cyanide causes other dangerous chemicals to be stuck in the lungs and airways.

Carbon monoxide

Carbon monoxide is a colourless gas with no smell. It is formed when we burn carbon-based fuels, such as gas in cookers or petrol in car engines. It can make up as much as 3-5% of tobacco smoke.

Carbon monoxide sticks to our red blood cells in place of oxygen. This lowers our blood’s ability to transport oxygen and deprives our tissues and organs of this vital gas.

Like hydrogen cyanide, it kills cilia and reduces our lungs’ ability to clear away toxins. This means that while carbon monoxide does not cause cancer directly, it makes it easier for other chemicals to do so.

Nitrogen oxide

Nitrogen oxide is a gas found in car exhaust and tobacco smoke.

Our bodies use it in very small amounts to carry signals between cells. But in large amounts, it is a major air pollutant. It directly damages lung tissue and causes inflammation in the lungs.

Normally, our bodies produce small amounts of nitrogen oxide, which causes our airways to expand. The large amount of nitrogen oxide in tobacco smoke changes things in two ways:

When smokers are smoking, it expands their airways even further, making it easier for their lungs to absorb nicotine and other chemicals.
When they are not smoking, it shuts off their internal nitrogen oxide production line, causing their airways to constrict. This is one reason why regular smokers often have difficulty breathing.


Ammonia

Ammonia is a gas with a strong, irritating smell, and is used in some toilet cleaners. Some studies have found that ammonia enhances the addictive power of nicotine. It changes nicotine into a gas that is more readily absorbed into the lungs, airways and bloodstream.

Like carbon monoxide and hydrogen cyanide, ammonia also kills cilia.

More poisons

Tobacco smoke also contains many other poisons that produce harmful effects. These can be carried throughout the body via our blood vessels.

As well as hydrogen cyanide and ammonia, gases like sulphur dioxide also kill cilia (protective hairs) in our lungs. This stops them from being able to clear away other harmful chemicals.

Chemicals like hydrogen sulphide and pyridine irritate our airways.

Toluene can damage brain cells and interfere with their development.

killing us softly ika nga...

to all smokers... i know you can't quit that habit,

but it is killing us softly.....

ever heard of 2nd hand smoke?

me aunt in US was a victim, she died of Lung cancer... and yet, she is a non-smoker....

Meron akong kapitbahay na malakas manigarilyo....lampas na ng 50 ang edad, malaking tao, tropa ng isang Biker na CYCAD. Umaga, tanghali at gabi amoy na amoy dito sa bahay ang usok nya. Past-time nya ang GIN at Yosi kada tapos ng trabaho, minsan inalok ko ng SML...ayaw nya daw ang lasa.

Isang araw bigla na lang syang dumura ng dugo....pinacheck-up, ang resulta. Malala na ang sakit nya sa baga. Isang baga na lang ang nakikita sa x-ray, naninilaw na rin ang kanyang kulay dahil apektado na ang kanyang atay dahil sa GIN na gustong-gusto nya. Ang dating malaking katawan na ngayon isang manipis na lang dahil sa kapayatan. Nakakaawa sya dahil halos 24/7 syang umuubo walang humpay. Nakakaawa pero ginusto nya ang bisyo.

Walang maitutulong ang YOSI at alak sa katawan pag inabuso...balang-araw aabalahin mo pa ang mga MAHAL MO SA BUHAY para alagaan ka pag malala na ang iyong sakit.

Maawa ka naman sa kanila. Ngayon pa lang.....itigil nyo na ang YOSI.

Kaso lang kung CAN AFFORD mo naman ang Hospital BILL....GO!, it's your LIFE.

Charge to your experience naman yan....
