Then shot to stop smoking aids came to treat nicotine addiction by healing the center of addiction in your brain.

How dangerous is smoking ?

Chemicals found in the cigarettes are dangerous or poisonous to your body, many responsible for causing cancer disease, especially lung cancer. What kind of chemicals are there? Here are the list of those chemicals :

Nicotine - This is the substance that make you want to smoking again continuously or addiction. Found in tobacco as protection from insect.

Tar - is collection of solid particles inhaled as mixture of many chemical cause cancer.  When it settles, tar forms a sticky, brown residue that can stain smokers’ teeth, fingers and lungs.

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

Benzene - is a solvent used to manufacture other chemicals, including petrol. It is well-established that benzene can cause cancer, particularly leukaemia.

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. It is a known cause of cancer, and can also damage the kidneys and the linings of the arteries.

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. Also a known cause of cancer.

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. Tobacco smoke contains traces of polonium, which become deposited inside their airways and deliver radiation directly to surrounding cells.

Chromium - is a metal used to make metallic alloys, dyes and paints and comes in different types. chromium VI or ‘hexavalent chromium’ is very toxic, is found in tobacco smoke, and is known to cause lung cancer.

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 - is 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.

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

Others chemicals: 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

Deseases you will probably have after long term smoking:

Cancer: mostly lung cancer. Cigarette smoking causes 87 percent of lung cancer deaths. Smoking is also responsible for most cancers of the larynx, oral cavity and pharynx, esophagus, and bladder. In addition, it is a cause of kidney, pancreatic, cervical, and stomach cancers, as well as acute myeloid leukemia. Others deseases are heart disease, stroke, and respiratory illnesses.

Those chemicals causing deadly disease found in cigarettes should make you fear of death. Don’t you? Then quit smoking right now or you’re gonna regret someday.
