Smoking Effect

Smoking - effects on your body
Nicotine is the addictive drug in tobacco smoke that causes smokers to continue to smoke. Addicted smokers need enough nicotine over a day to ‘feel normal’ – to satisfy cravings or control their mood. How much nicotine a smoker needs determines how much smoke they are likely to inhale, no matter what type of cigarette they smoke.

Along with nicotine, smokers also inhale about 4,000 other chemicals in cigarette smoke. Many of these compounds are chemically active and trigger profound and damaging changes in the body. There are over 60 known cancer-causing chemicals in tobacco smoke. Smoking harms nearly every organ in the body, causing many diseases and reducing health in general.Tobacco smoke contains dangerous chemicals
The most damaging compounds in tobacco smoke include:

* Tar – this is the collective term for all the various particles suspended in tobacco smoke. The particles contain chemicals including several cancer-causing substances. Tar is sticky and brown and stains teeth, fingernails and lung tissue. Tar contains the carcinogen benzo(a)pyrene that is known to trigger tumour development (cancer).
* Carbon monoxide – this odourless gas is fatal in large doses because it takes the place of oxygen in the blood. Each red blood cell contains a protein called haemoglobin; oxygen molecules are transported around the body by binding to, or hanging onto, this protein. However, carbon monoxide binds to haemoglobin better than oxygen. This means that less oxygen reaches the brain, heart, muscles and other organs.
* Hydrogen cyanide – the lungs contain tiny hairs (cilia) that help to clean the lungs by moving foreign substances out. Hydrogen cyanide stops this lung clearance system from working properly, which means the poisonous chemicals in tobacco smoke can build up inside the lungs. Other chemicals in smoke that damage the lungs include hydrocarbons, nitrous oxides, organic acids, phenols and oxidising agents.
* Free radicals – these highly reactive chemicals can damage the heart muscles and blood vessels. They react with cholesterol, leading to the build-up of fatty material on artery walls. Their actions lead to heart disease, stroke and blood vessel disease.
* Metals – tobacco smoke contains dangerous metals including arsenic, cadmium and lead. Several of these metals are carcinogenic.
* Radioactive compounds – tobacco smoke contains radioactive compounds, which are known to be carcinogenic

The male body
The specific effects of tobacco smoke on the male body include:
* Lower sperm count
* Higher percentage of deformed sperm
* Reduced sperm mobility
* Changed levels of male sex hormones
* Impotence, which may be due to the effects of smoking on blood flow and damage to the blood vessels of the penis.

The female body
The specific effects of tobacco smoke on the female body include:
* Reduced fertility
* Menstrual cycle irregularities or absence of menstruation
* Menopause reached one or two years earlier
* Increased risk of cancer of the cervix
* Greatly increased risk of stroke and heart attack if the smoker is aged over 35 years and taking the oral contraceptive pill.

The unborn baby
The effects of maternal smoking on an unborn baby include:
* Increased risk of miscarriage, stillbirth and premature birth.
* Low birth weight, which may have a lasting effect of the growth and development of children. Low birth weight is associated with an increased risk for early puberty and, in adulthood, is an increased risk for heart disease, stroke, high blood pressure and diabetes.
* Increased risk of cleft palate and cleft lip.
* Paternal smoking can also harm the foetus if the non-smoking mother is exposed to secondhand smoke.
* If the mother continues to smoke during her baby’s first year of life, the child has an increased risk of ear infections, respiratory illnesses such as pneumonia, croup and bronchitis, sudden infant death syndrome (SIDS) and meningococcal disease.

Diseases caused by long-term smoking
A lifetime smoker is at high risk of developing a range of potentially lethal diseases, including:
* Cancer of the lung, mouth, nose, voice box, tongue, nasal sinus, oesophagus, throat, pancreas, bone marrow (myeloid leukaemia), kidney, cervix, ureter, liver, bladder and stomach.
* Lung diseases such as chronic obstructive pulmonary disease, which includes chronic bronchitis and emphysema.
* Coronary artery disease, heart disease, heart attack and stroke.
* Ulcers of the digestive system.
* Osteoporosis and hip fracture.
* Poor blood circulation in feet and hands, which can lead to pain and, in severe cases, gangrene and amputation.

Nicotine Effects on the Body, Effects of Cigarettes
After a relatively short time, a smoker is often already significantly dependent on nicotine. Smokers who have an addiction problem usually smoke a cigarette in the morning - often within half an hour of waking up. They can stop smoking, if they try, but only for a few weeks at a time. Addiction is an emotionally charged word that is often associated with using drugs. But smoking also shares all the effects on the body of other addictive drugs. When a smoker feels the need to smoke and feels uncomfortable, the reason is that the level of nicotine in the body has been reduced below some value. After the first puff on a new cigarette, nicotine is back in the brain within 7 seconds. So the effect of a new dose of nicotine is quickly noticeable. This way the nicotine causes physical dependence. The body wants to get the new substance over and over again.

However, an addiction to nicotine can be cured. Most smokers can even do it without help. It's clear, though, that the will to stop and the effort to succeed are very important.

The smoker often deals with a double addiction. In addition to the direct effect of nicotine on the body, as described above, there are all kinds of moments, all day long, that more or less ask for a cigarette. It is very hard for many smokers to break that pattern; it is a form of mental dependence. Because smokers smoke after eating, when drinking coffee, while having a drink, during a phone call, in the car, at work, during a break, after having sex, in front of the television, after a game, when not? And even if there is not a direct reason to smoke, they do. Just because they are used to it. A smoker who stops smoking sits with empty hands on many occasions, and at first, that feels very uncomfortable.

Early smokers notice the nasty effects of the nicotine, and are initially discouraged from smoking another cigarette. Youngsters who just started smoking often resolve not to get addicted or to quit smoking before they become addicted. When you haven't yet started to smoke every day, this seems a good plan, and maybe also when you smoke less then 2 or 3 cigarettes a day, but you rarely stop at those few cigarettes. Influenced by the people around you (smoking friends who softly urge you to smoke along), smoking gradually becomes a normal thing. A night out, at a movie, a disco or a bar; smoking is still standard in many places. That way young people start to smoke more often. Gradually, the body gets more and more used to the nicotine, the need to smoke increases and you develop the habit and addiction that adult smokers know so well and that means that you can't function without your cigarette anymore.
Please stop smoking right now..!! View for the step..
