The influence and effects of nicotine on the human body. The effect of nicotine on the human cardiovascular system. The effect of nicotine on the human nervous system

The substance nicotine is a special alkaloid that is synthesized in the accumulated leaves of plants and their roots.

Most of it is found in tobacco. It should be noted that this substance has an extremely negative effect on the human body, since by its nature it is a neurotoxin.

With regular penetration of nicotine into the respiratory system, a person develops a very strong addiction.

The effect of nicotine, in particular tobacco smoke (the smell on humans), is quite dangerous.

At the same time, it does not matter how exactly the smoke will be inhaled - in the form electronic cigarette or regular tobacco smoking. In any case, the body will be poisoned every time.

What does it contain?

As noted above, greatest content nicotine is observed in the nightshade family of plants, namely in tobacco leaves. Less of this substance is observed in tomatoes, shag, potatoes and green peppers. In a small group, nicotine compounds are found in coca leaves.

Nicotine addiction and substance use

Today, you can use nicotine in several ways, namely:

1. Chewing tobacco. This method is not very common. It is usually used when nicotine addiction in the withdrawal stage, when a person experiences a pronounced physical as well as psychological need for nicotine.
2. Inhalation of special snuff . This method The use of nicotine is one of the most dangerous, since in this case a person inhales tobacco leaves through the nose, which in turn can provoke nosebleeds, inflammation and other complications.
3. Smoking tobacco. This method is by far the most common. At the same time, in order for nicotine to enter the body, a person will only need to smoke several cigarettes or a hookah filled with tobacco.

Once in the mouth and lungs, nicotine is absorbed quite quickly. It is also able to penetrate the body even through intact skin.

Immediately after entering the body, this substance quickly spreads through the blood. According to latest research It only takes seven seconds after inhaling cigarette smoke for nicotine to reach the brain.

Nicotine is eliminated within two hours. Its absorption largely depends on the number of filters and the type of tobacco.

It is important to note that when you inhale tobacco through your nose or chew it in your mouth, much more pure nicotine enters your body than when you normally smoke tobacco.

Effect of nicotine

The narcotic effect of nicotine occurs very quickly. To my original level this alkaloid returns a couple of hours after the initial intake. Nicotine is completely eliminated from the body within two days.

The effect of nicotine on a person is initially determined by its effect on nerve connections (synapses).

In no large doses nicotine can provoke the development of the following symptoms in a person:

• Increased heart rate.
• Increased production of adrenaline in the body.
• The development of special mediators in the central nervous system, which in turn contribute to an active psychomodulatory effect.
• Increased blood pressure.
• Vasoconstriction.

The effect of nicotine on the human body

If nicotine addiction is not treated, the effect of this substance on the human body will be extremely negative. It is important to say that in one a regular cigarette contains about 1.30 mg of nicotine, which, when administered intravenously, can become a lethal dose for humans.

When regularly introduced into the body, nicotine contributes to the development of a dependence syndrome in a person, which in turn can be both physical and psychological. This leads to the need for an already dependent person to regularly smoke or inhale tobacco smoke. Sometimes such a condition requires serious treatment in narcology if it is in an advanced stage.

Nicotine has a very strong effect on nervous system person. When exposed to large doses of this substance, a person may experience euphoria, a surge of strength, a sense of mental clarity and joy. Gradually, the habit of smoking turns into a special ritual that forms an integral part of life.

Nicotine addiction has a very strong effect on the respiratory system. Consequently heavy smokers susceptible to lung cancer chronic form bronchitis and persistent cough.

According to recent studies, it has been found that regular smoking leads to vasoconstriction and significantly increases the likelihood of developing atherosclerosis.

The effects of nicotine on women and men are considered very dangerous. reproductive system. Thus, in women, smoking increases the likelihood of pathologies in the fetus, miscarriage, fading of pregnancy, as well as a decrease in the production of a number of important hormones.

As for men, nicotine helps reduce potency in them, and also leads to infertility due to “lethargy” of sperm.

According to statistics, every tenth couple today faces the problem of infertility. Moreover, more than 50% of all cases of infertility are associated with long-term smoking.

If we consider nicotine with scientific point From the point of view, this is nothing more than a poison, which in any case, if it enters the body, will cause harm to it. Those people who smoke several cigarettes a day are especially at risk of suffering from this substance.

The harm of nicotine and possible consequences of its use

Not everyone knows how dangerous nicotine is and what consequences this bad habit can lead to. It should be noted that the harm of nicotine in its primary manifestation will be noticeable after a couple of months of constant smoking (from two to six months). In this condition, a person may experience a dry cough, sleep disturbances and awakening at a very early time.

This period is accompanied by the formation of a mild mental dependence, from which a person can get rid of it with the desire and certain efforts.

With constant smoking for several years, a person develops a severe form of mental, as well as physical dependence from nicotine. The poison contained in this substance affects the central nervous system and also affects autonomic system. With regular intake of nicotine, a person may experience central nervous system paralysis, respiratory arrest, and acute disorder heart rate.

The harm of nicotine is quite varied, however, when consumed in minimal doses, this substance can act on a person as a powerful psychostimulant, promoting the release of adrenaline. This, in turn, will provoke a feeling of liveliness, a surge of strength, and calm. Sometimes nicotine reduces appetite and increases metabolism, which in turn has a beneficial effect on weight loss.

The danger of nicotine is determined by its ability to infect different systems body: respiratory, cardiovascular, nervous, vegetative, digestive, etc. The harm of nicotine to the lungs is also undeniable, since chronic smoking significantly increases the development of cancer in humans.

To better understand why nicotine is dangerous, it is important to indicate exactly what consequences its systematic entry into the body leads to.

Thus, chronic smoking can cause the following diseases in humans:

Nicotine poisoning

If the permissible dose of nicotine enters the body is exceeded, a person will be left with this substance.

In this condition, the patient may experience quite different signs diseases, but most characteristic symptoms similar condition are:

It is important to note that nicotine poisoning most often occurs when smoking a large number of cigarettes over a period of time. a short time(2-3 hours). Sometimes the poisoning is so severe that the patient’s heart stops and complete paralysis of the respiratory system occurs, which in turn causes death.

That is why, when the first signs of nicotine poisoning appear, a person needs to call a doctor as soon as possible, and before his arrival, take a number of medications recommended by the doctor.

Nicotine addiction

With regular ingestion of nicotine into the body, this substance contributes to the gradual formation of addiction in a person, which can be psychological and physical. At the same time, in most cases, the addict himself does not notice when he can no longer live a day without a cigarette.

Physical dependence on nicotine occurs when the body can no longer live without this substance and its lack provokes severe discomfort and even painful sensations. Moreover, abrupt cessation of smoking affects the functioning of the heart, leading to headaches, weakness and decreased ability to work.

According to doctors, it is much easier to get rid of physical addiction than psychological one. To do this, a person only needs to take medications prescribed by a doctor, which are intended specifically to relieve symptoms that develop when quitting smoking.

It is much more difficult to eliminate psychological dependence, which consists of forming a habit in a person. Moreover, for many young people smoking is a method of self-affirmation. With its help, they try to fill pauses in communication and awkward moments that often arise in adolescence.

With regular smoking, this habit becomes the only way to relax. Moreover, due to the fact that nicotine promotes arousal in the body, a person will try to smoke as often as possible in order to prolong this feeling.

To quit smoking forever, you first need a specific goal and excellent self-control. You will also need a person’s desire to remove the poison from the body and considerable willpower to be able to endure possible consequences abrupt cessation of smoking.

Sometimes a person cannot cope with nicotine addiction on his own. In this case, he is recommended to consult a narcologist and take prescribed medications, for example, Zyban. In most cases, for complete drug elimination Nicotine addiction takes several months to a year. At the same time, it is important that a person does not lose his temper and does not smoke even one cigarette a day, otherwise special effect there won't be any from therapy.

It is important to note that quitting nicotine provokes an increase in appetite, which often leads to uncontrolled food consumption and speed dial weight. For this reason, there is no need to go from one extreme to another, and if you have already given up nicotine, then you should carefully monitor your diet.

Smoking, according to experts, is global problem, which affects all countries of the world and all sectors of society. The effect of nicotine on the body is harmful, but a person begins to think about it only when he develops a serious and sometimes fatal disease. Let's not brush aside the problem, wanting to justify our bad habits, our lack of education in terms of medicine and culture of life. It is better to find out how smoking affects health, and then everyone chooses for himself what is more important to him - joy, family, work, leisure or a hospital ward.

Composition of tobacco smoke

When we inhale cigarette smoke, we don’t even think about what powerful poisons enter our body. And what disastrous consequences does this lead to? In a year, two, 10 years. All substances are extremely harmful, each causes one or another disease, which can be extremely difficult or impossible to cope with.

So, what are they chemical elements present in cigarette smoke?

• When the cigarette is lit, dry distillation of the tobacco occurs. This process is accompanied by the formation of a large number of harmful substances: nicotine, carcinogenic carbohydrates, formaldehyde, ammonia, hydrocyanic acid, carbon monoxide, butyric, acetic, formic and valeric acids, carbohydrates, essential oils, acrolein, hydrogen sulfide, lutidine, soot, aniline, ammonium oxide, pectin, pyradine, ammonium acetate, collidine and others.
• The most harmful component of tobacco is nicotine. It is an oily, transparent, colorless liquid with a pungent taste. When poisoned by nicotine, the central nervous system is affected. Headaches, nausea, vomiting, memory loss, and decreased performance are observed. IN severe cases convulsions and loss of consciousness occur. With each cigarette smoked, a person receives 0.533 mg of nicotine.

Resins. Settle on inner surface lungs in the form of a black coating. They cause cancer, paralysis of the lung cleansing system, damage to the alveolar sacs, and lead to many diseases of the respiratory system.

Carcinogens. Cause mutations in cells, provoke oncological diseases, reduce immunity.

Nitrosamines. They cause cancer of the lungs, esophagus, pancreas, oral cavity.

Carbon monoxide. Interferes with normal blood circulation, causes increased stress on the heart, lungs, and blood vessels. Promotes spasm coronary arteries, damages their walls.

Polonium 210. Get in nuclear reactors by irradiating bismuth isotopes. Enters the human body along with cigarette smoke. Very toxic due to alpha particle radiation. By smoking one cigarette, a person gets so much heavy metals, how much he would get by inhaling exhaust fumes for 16 hours.

Hydrogen cyanide or hydrocyanic acid. Promotes heart and vascular diseases, the development of myocardial infarction, and poisons the body as a whole.

76 metals. They are found in tobacco smoke and act as carcinogens.

The scary list goes on and on. But what is said here is enough to quit smoking immediately.

Effect of nicotine on the central nervous system

Cigarette smoke negatively affects the activity of the central nervous system. Smoking leads to sleep disorders, excessive excitability, inability to concentrate, excessive irritability. Nicotine affects the spinal cord, nerve fibers, and brain tissue. The conductivity of neurons is disrupted, which leads to various diseases. Smokers quite often experience cerebral vascular sclerosis, radiculitis, neuritis, polyneuritis, and vascular spasms. Headaches, memory disorders, hand tremors, decreased mood, and dizziness are also common. A persistent dependence on cigarettes develops.

The effect of nicotine on the cardiovascular system

Smoking is one of the factors in the development of severe forms of atherosclerosis, and this in turn provokes the progression of diseases such as stroke, obliterating endarteritis lower limbs, aortic aneurysm, coronary heart disease, hypertension, heart failure. Cholesterol plaques clog blood vessels, reduce their permeability to blood, which threatens cerebral circulation disorders, strokes and heart attacks.

Diseases such as endarteritis obliterans and thromboangiitis obliterans in young people occur only in smokers. Nicotine causes vasospasm, which causes increased heart rate and causes premature wear of the heart muscle. You should know that such changes in the body are irreversible.

The effect of nicotine on the sexual sphere

As a rule, smoking causes hormonal imbalance in the body, since circulatory disorders have a detrimental effect on the organs internal secretion, in particular, on the pituitary gland and hypothalamus. Hence, erectile dysfunction, prostatitis, prostate adenoma, decreased libido in women, and the development of malignant and benign tumors reproductive organs.

The most common diseases associated with smoking

• Smokers are constantly at risk. They have more often than non-smoking people, serious illnesses occur.
• Chronic gastritis of a smoker, stomach pain, white coating on the tongue, bad breath, cancer of the stomach and esophagus.
• Damage to the lower extremities due to vascular spasms, pain in the legs, trophic ulcers, gangrene.
• Disturbances in the functioning of the heart, shortness of breath, weakness, sweating, low performance, heart pain, heart attack, angina pectoris.
• Cancer vocal cords, tongue, papillomatosis of the vocal cords.
• Lung cancer, bronchial cancer, Chronical bronchitis smoker, frequent cough, morning cough.
• Diseases of the mammary glands in women, breast cancer.
• Uterine cancer, cervical cancer due to hypoxia, circulatory disorders in the tissues of the reproductive organs.
• Impotence in men, prostate cancer, genital carcinomatosis.

Take care of your health, give up cigarettes, because addiction to smoking is a direct path to nowhere.

Smoking is the most common bad habit of humanity. The ease of production of cigarettes allows them to be produced in unlimited quantities, and advertising makes them as popular as possible among people. Smoking is becoming increasingly popular as a process that is similar to a ritual, a psychological action. Nicotine reaching the lungs along with smoke is absorbed into the capillaries.

This is where the gas exchange process takes place. Next, nicotine enters circulatory system, from where it is sent directly to the brain. The effect of nicotine on the human body is dangerous, therefore, not wanting to get rid of addiction, a person must be aware of the problems that a seemingly harmless addiction can bring to him.

How does nicotine affect a person?

The effect of nicotine on the human body is destructive. Smokers are most susceptible to developing a variety of diseases. Nicotine is an oily liquid with a bitter aftertaste. This component is toxic. Consumption of 1 mg/kg may cause death in humans.

Tobacco becomes especially dangerous for people who have reached 15–20 years of experience. Due to the intake of nicotine in the body, almost all organs and systems suffer. Smoker's lungs and healthy person not identical. Functions internal organs pathologies are disrupted and developed. Very often smokers suffer from:

• ulcer;
• chronic gastritis;
• inflammatory process of the pancreas;
• problems with erection;
• infertility;
• complications when bearing a child;
• high blood sugar;
• hypertension;
• hypovitaminosis;
• atherosclerosis;
• coronary heart disease;
• myocardial infarction.

The most harmful effects on the body are nicotine and various tars contained in cigarettes. They cause diseases such as cancer of the larynx, mouth and lungs. The lungs of a smoker, after 15 years of smoking experience, die and lead to fatal outcome in terrible agony.

What do smoker's lungs look like? In order to realize the seriousness of the problem, just look at the comparative photo. After smoking, the lungs become dark, lifeless and, of course, cease to function normally. Nicotine also causes frequent manifestations of stomatitis.

A smoker's lungs undergo major changes

Nicotine and fertility

Nicotine has a negative effect on fertility in both sexes. In men, smoking causes:

• erection problems;
• disturbance of spermatogenesis;
• development of infertility;
• the occurrence of prostate cancer.

Toxic compounds provoke the development oxygen starvation brain cells. This is where the center for regulating sexual function is located. Nicotine, which disrupts the process of seminal fluid accumulation, reduces the level of sperm density and reduces the number of germ cells.

Male smokers quickly become impotent. Women who smoke provoke a decrease in the level of prolactin in the body, which causes a violation menstrual cycle. Gradually, the fair sex becomes infertile.

Smoking during pregnancy is unacceptable! It can lead to:

• to fetal hypoxia;
• development of defects;
• decreased breathing rate;
• increased risk of sudden death in an infant;
• premature birth.

Nicotine and indigestion

Nicotine entering the body has negative impact on digestive system. The most common problems that smoking causes are:

• with tooth enamel;
• lips;
• oral mucosa;
• pharynx;
• esophagus;
• mucous membrane;
• liver;
• pancreas;
• intestinal mucosa.

Nicotine in most cases causes gastritis due to systematic irritation of the gastrointestinal mucosa. Tobacco causes disruption of gastric motor function. Smoking just a couple of cigarettes daily slows down food digestion by 2-3 times. The level of enzyme secretion decreases, which leads to gland atrophy. This is considered a clear sign of gastritis.

If you have appropriate symptoms, it will be useful to take medications as prescribed by your doctor. Such diseases are considered precancerous diseases and soon lead to the formation of malignant tumors. Taking medication and quitting the habit will help restore your health. Some smokers report a decrease in appetite. In such cases, a person quickly loses weight and becomes painfully thin.

Effects on blood vessels and heart

Tobacco poses the greatest danger to the cardiovascular system. Nervous and humoral regulation is disrupted, which impedes blood circulation and causes the early death of the smoker. Nicotine increases the production of adrenaline and norepinephrine. Tobacco shortens a person's life by 8–15 years. Accelerated contractions of the heart muscle leads to vasoconstriction. Constant stay in a state of vasospasm provokes the development arterial hypertension. A smoker with 15 years of experience cannot boast of good health.

Only quitting smoking will prolong the life of someone who likes to relax with a cigarette.

Systematic enjoyment of a cigarette causes calcium deficiency in an experienced smoker, which reduces the contractility of muscle tissue.

Without parting with a cigarette for about 5 years, a smoker acquires cardiac hypertrophy, the appearance of atherosclerotic plaques, and loss of vascular elasticity. Ischemic disease heart disease occurs against the background of atherosclerosis. People who smoke are more likely to suffer from heart problems. Every year he dies a large number of people with heart disease that developed due to cigarette abuse. How many more years must pass before a person realizes how nicotine affects the body?

What else could be dangerous?

The effects of nicotine on the body are harmful! This becomes obvious if you look at the organs of a smoker and a non-smoker. A lot of cells die in a smoker's lungs every day. Tobacco is considered a powerful neurotoxin. It promotes sharp stimulation of the nervous system and its further depression. Against this background, problems often arise:

• with memory;
• attention is impaired;
• headache occurs;
• worried about radiculitis;
• suffer from dizziness;
• neuritis and polyneuritis occur.

Smoking can cause decreased vision or hearing problems. Whenever a smoker tries to quit his bad habit his condition worsens sharply, and the craving for tobacco causes withdrawal symptoms every hour. Psychological comfort in this case can be achieved only while smoking a cigarette.

Smoke that is inhaled is dangerous to respiratory organs. Irritation often occurs against the background of tobacco and develops inflammatory process mucous membrane of the oral cavity, trachea, bronchi. People who smoke begin to suffer from frequent bronchitis, which can subsequently lead to respiratory failure. Nicotine also leads to lung cancer. After smoking, the lungs cannot fully perform their function.

Before planning a child, you should completely get rid of addiction

A woman who has smoked for a long period of time must undergo an x-ray and cure her nicotine addiction before planning a child. Be sure to check the results of fluorography with the future father. You can even cleanse the body and blood vessels folk remedies. You can check with a narcologist which medications can be taken to speed up the body’s recovery. To cleanse the body, you should also drink milk daily. We clean black spots on the lungs, including garlic in the menu, green tea and pineapples.

The corresponding pictures on the Internet can show the approximate condition and appearance experienced smoker. Decline immune system causes hypovitaminosis and an increased risk of developing diseases such as tuberculosis. Unfortunately, even a non-smoking person being next to a smoker is harmful to health. Nicotine is poison! That is why it is worth giving up your addiction as soon as possible and, if necessary, undergoing treatment with pills.

The effect of nicotine on the body is known to many own experience. Every smoker experiences its effects on himself every day. But no one really bothers about what nicotine actually is, and what happens when it is in the body.
Nicotine is a plant-type alkaloid. Entering the human body, it begins to rapidly spread, which is carried out through the bloodstream. The most important property of nicotine is that it is quickly and highly addictive, which is why a person needs to constantly consume it. As a result, a strong dependence develops, which has a negative impact on health in the future.
Without attaching much importance to smoking, people ruin themselves day after day. Not everyone thinks that nicotine will develop some processes in the body’s systems, he knows one thing - he urgently needs another dose of his favorite nicotine, because it helps with stress and, in general, is his best “friend” when bad mood.
However, scientists who are puzzled by the health of the population take their heads when across the planet the number of people with developing diseases increases every day. serious illnesses, not of a cold nature.
The incidence is growing more and more every year. Doctors, studying people as a whole, tried to understand what was happening and why the number was increasing so sharply the most dangerous diseases. People began to be vaccinated against various dangerous diseases, various analyzing procedures were carried out, but this did not bring results. The number of patients grew, but no cause was identified.
But time passed and yet professors all over the planet came to the conclusion that the most main reason, due to which the most various diseases- this is smoking. Of course, the ecology, atmosphere, food and water are also involved in destructive processes, but in comparison with smoking, they are truly divine.
And the most deplorable thing in this situation is that along with the incidence of the disease, the number of smokers is growing. Statistical studies do not influence people's decisions in any way and do not provide any motivation not to start smoking.

But, nevertheless, there are exceptions who also still want to understand why smoking can kill.

• Does the body need nicotine? Nicotine helps stimulate breathing and can have a relaxing effect - this is what can cause a smoker to think that if this is so, then it is good. But this is only a visible deception. Nicotine does have these effects, but not in the way you might imagine. Starting to smoke, a certain stimulation and relaxation actually occurs, as a result of which, in any stressful situation, you just need to take a cigarette, take a puff and feel calm and relaxation. With each subsequent puff, this effect will pass and the person will only develop false feeling that he is stressed and urgently needs to take “medicine”. This is how addiction develops. After long-term use Nicotine causes withdrawal syndrome, which consists in the fact that the same stimulation of breathing stops. It causes severe discomfort. Also, nicotine is absorbed into the blood and disrupts work and function. shaped elements blood (erythrocytes, platelets and leukocytes). There is a frequent development of blood clots, which leads to irreparable consequences. Due to disruption of blood flow, the most basic organs, such as the lungs, heart, brain and others, also suffer. Therefore, we can conclude that the body does not need nicotine at all, at least in the form in which it comes through a cigarette. On the contrary, it is necessary to make every possible effort to protect yourself from nicotine.
• Nicotine production in the body. This is exactly what has become a popular question lately: is there nicotine in the body? And by this we mean the body’s independent reproduction of nicotine. Here we can say it very simply: one misunderstood, and the other smashed it the way he was given to understand, according to the principle of a broken telephone. Very often, when people read any information, they do not fully understand the essence of its content, and as a result, it turns out that absolutely unfounded conversations appear. In this case, the same can be said. Now, information is circulating freely on the Internet that the liver is capable of producing nicotine, but this is not entirely true, although we can say that to some extent this information is correct, but not in the interpretation in which it is presented. In fact, the body is capable of forming ammonia derivatives, such as amines, and these include nicotine. As you know, amines are produced in literally every piece of tissue, at certain moments of metabolism. But they are not the nicotine found in cigarettes, and that is exactly what we are talking about. Therefore, this statement can be called spam.
  
  
• It's a different story when it comes to nicotinic acid, which can make you feel like it's the same thing as nicotine. Here we can definitely say that a nicotinic acid actually found in the body, it is a vitamin that is important for many oxidative processes in living organisms. But, despite the fairly similar name, these two substances have nothing in common; they belong to different categories of substances and cannot be compared.
• The effects of nicotine on the human body. This issue is very subtle and requires a separate description, which will be the subject of the continuation of the article. But in more detail.

How nicotine affects the body

Nicotine can affect the body from different sides, not only through the lungs, but also through the skin and mucous membranes.
As mentioned above, once inside, nicotine is absorbed into the blood, but it does this not only through the lungs, but also through the vessels that are located immediately under the skin and mucous membranes. Then, through numerous ducts, it begins to spread to all parts of our body.
The most dangerous thing is inhaling nicotine, since this fills the oral cavity, larynx, trachea, and lungs, while producing irritating effects. Afterwards, the spread of poison to all systems begins with the blood.

• Nicotine causes enormous harm to the lungs, since gas exchange occurs in them, and due to the fact that nicotine is located there, it worsens this process and from there nicotine is very easily absorbed into the smallest
  cells of adjacent tissues.
• Through the bloodstream, blood flows to absolutely all systems human body. The main significance is the brain and heart; for these two organs, blood is simply necessary, and precisely in the composition as it exists, with all the complex that is inherent in nature. When blood soaked in nicotine passes through the bloodstream and enriches these organs, dissonance occurs for the body. For him this is something foreign. Then the processes of rejection and poisoning begin. However, nicotine is a powerful opponent and often wins defensive battles. As a result, heart defects develop (myocardial infarction, angina, hypertensive crisis, arrhythmia, hypoxia, headaches, nausea, vomiting, loss of sensitivity and taste, loss of consciousness, and many other problems).
• Nicotine also has a detrimental effect on the respiratory system and muscle growth. Entering the blood, nicotine thickens the blood, which disrupts the passage of blood through the vessels, veins and arteries. As a result, the lungs suffer due to lack of oxygen. The synthesis of muscles from proteins that enter the body deteriorates, which means that muscle growth in this situation reduces its speed. This is especially dangerous for teenagers who have recently become very interested in smoking, believing that this will give them some experience.
• No less severe harm occurs on reproductive system, both men and women. In men, as a rule, this manifests itself in deterioration of potency, decreased attraction to women, obesity, and decreased fertility. In women - disruption of the menstrual cycle, death of laid eggs, which reduces the possibility of further conceiving and bearing a child, development cancer diseases related to the possibility of having children.
• Smoking also deteriorates a person’s appearance: teeth and nails turn yellow and break; severe hair loss; the condition of the skin worsens, it begins to age earlier; There is an unpleasant odor from the mouth and hands. These are external and primary symptoms of the fact that the body has begun to bad processes, which could only develop. These manifestations are the beginning of the process of “rotting” of a person, when all organs and systems fail in turn.
• All smokers know that when smoking they often want to go to the toilet. This is not good, since the kidneys are forced to work at their maximum, as a result of which they may at one moment simply not cope with the task that is entrusted to them. Smoking can cause increased cholesterol levels in the blood, which can lead to diabetes mellitus, which is associated with the kidneys. Cigarettes also contain components that are poisonous to the human being. This is due to the fact that very important processes occur in the kidneys, such as blood filtration. Due to impaired kidney function, their important filtration processes will also inhibit their activity, as a result, the blood does not contain what is necessary, or, on the contrary, due to insufficient processing, it may contain harmful substances. This proves that, despite the fact that nicotine does not directly affect the kidneys, they still suffer. This confirms the fact that nicotine is the killer of everything.
• It also has a bad effect on the liver and intestines. Here, in principle, the same thing happens. Due to a disruption or deterioration in functioning, a malfunction occurs in a certain organ, and, as everyone knows, the body is a complex system in which everything is interconnected; if any organ fails, it takes the rest with it, not less important organs. As a result, just because a person smokes, he can spend the rest of his life on various medications, which in turn also worsens the functioning of the body. All this leads to the fact that old life no longer will be, since we receive our health at birth, as a hereditary trait. Our health is established in utero, it cannot be changed, but can be maintained. Or kill. Here the choice is up to everyone.
• And lastly, probably the most relevant, is how smoking affects the fetus. Everything is simple and clear here. Firstly, at smoking woman, the chance of conceiving a child is reduced by exactly 50%, and if you manage to conceive, there is no guarantee that you will be able to carry it to term. Secondly, the risk increases ectopic pregnancy, frozen pregnancy, early and late miscarriages, early birth. Thirdly, at smoking parents, more often than others, children are born with heart, kidney, and hearing defects; they are more likely than others to have lower body weight and develop more slowly. It is much harder for children born from smoking parents, since they begin their lives with nicotine. Even during the prenatal period, their vital systems are disrupted and children are born with imperfect health, and often with imperfect lungs. For unborn children, smoking has the most strong effect, because, in essence, the child smokes with his mother. Even if it’s not mom but dad who smokes, this does not reduce the risk possible pathologies and mutations, but on the contrary, increases.
  This article only briefly described what can trigger smoking. In fact, if you consider each organ separately and in more detail, you can learn even more “interesting” things. But even from this a short story you can see that just a breath of nicotine deprives you normal life, correct and healthy. The main value of every person is his health, so it must be protected and supported. It is necessary to stop smoking so that an already unhealthy body, which is daily exposed to various natural and human harmful factors, causing problems and diseases, the poison contained in every sip of nicotine did not enter.

Few people talk about the benefits of nicotine. But on the topic that nicotine is harmful to human body, we can talk for a long time, based on scientific facts that scientists and others cite in their works. Cigarette packages also contain pictures that warn people about the health hazards of smoking.

Of course, there is some truth in this, people die from nicotine if they use it in excessive quantities, but we would like to talk about how nicotine is useful.

Is there any benefit to nicotine?

First, let's figure out why so much attention has been paid to the topic of the harmfulness of nicotine. Doctors have been studying this issue for many years and have provided a huge amount of evidence that there is no benefit in nicotine. But when a person smokes a cigarette, he simultaneously absorbs a lot of carcinogenic smoke, and nicotine has absolutely nothing to do with it.

On the contrary, if cigarettes contain very little nicotine, in this case they are harmful to human health, especially if the smoker is accustomed to inhaling deeply. Scientists have known about this for a long time, just talk about it now useful properties nicotine is not accepted. What other arguments have been given about the benefits of nicotine for the human body?

Nicotine negatively affects people's taste and olfactory receptors. That is why those who smoke taste food completely differently; it seems bland to them. Thanks to this, appetite decreases, and, as a result, it goes away. excess weight. For people suffering from obesity, this fact is just a godsend. The only thing is that appetite increases very strongly when a person tries to quit smoking. Then the kilograms return at a rapid pace.

1. Nicotine and Alzheimer's disease

In 1992, Dr. James Da'Fan made a great discovery about the benefits of nicotine. He convinced the whole world that smoking is great preventive method in the fight against Alzheimer's disease. According to the scientist, those who smoke almost never suffer from dementia in old age.

By the way, it should be noted that the scientist’s conclusion is not refuted by American doctors. They found that nicotine, when it enters the human body, begins to actively disintegrate in it, turning into “nornicotine” - a substance thanks to which brain neurons do not die. But it should also be noted here that the resulting substance is toxic, so you should not abuse cigarettes just to save yourself from the fate of facing Alzheimer's disease in old age.

2. Nicotine against Parkinson's disease

American scientists have discovered another fact about how nicotine is beneficial for humans.

The substance has a very beneficial effect on the genes of dopamine receptors, thanks to which old people can boast of good attention, they are always concentrated, but not long time. To maintain concentration, you need to constantly smoke a cigarette. But again, we must not forget about the toxicity of nicotine, which can simply destroy human health.

3. The beneficial effects of nicotine on the digestive system

Doctors in the field of gastroenterology have discovered another fact about how nicotine is beneficial. According to them, this substance reduces peristalsis in the intestines. After a person smokes several cigarettes, gas formation in the organs digestive tract noticeably decreases, because mucus in some parts of the intestine begins to be intensively produced under the influence of nicotine, and due to this, the likelihood of the formation of ulcerative colitis in humans. Moreover, those who smoke never experience diarrhea.

But in addition to the unambiguous benefits of nicotine, it is necessary to mention its harm - it is it that provokes the active development of cancer. According to WHO, smokers are the most likely to become victims of cancer.

4. The benefits of nicotine for women's health

American scientists believe that female hormone estrogen depends on the level of nicotine that enters the woman’s body. According to doctors from Dortmund, if a woman smokes, then she has:

• the risk of developing malignant tumors on the endometrium of the uterus is automatically reduced (due to the influence of nicotine, cells do not divide so quickly, especially cancerous ones);
• fibromatous nodes do not form on the uterus - that is, the connective tissue does not grow, because this process in the body is inhibited;
• Endometriosis never occurs in girls who started smoking in early age(this fact has not yet been scientifically proven, scientists are working in this direction to find a relationship);
• in pregnant women who smoke, nicotine prevents eclampsia - it does not increase arterial pressure, and preeclampsia - they do not develop gestosis, which can cause disruption cerebral circulation in mother and child. All these are only indirect advantages, which it is better for pregnant women to forget about if it is important to preserve the health of their baby and protect him from the possibility of being born with numerous defects of internal organs.

To this day, it has not been possible to determine exactly why such significant things happen in the body of a woman who smokes. There is an assumption that when tobacco gets into the lungs, it disintegrates and a potassium salt (thiocyanate) is formed, which has a very high hypotensive property, that is, the ability to lower blood pressure.

In addition, scientists from the USA have established many more facts about how nicotine is beneficial for women’s health.

These include the following items:

• Nicotine relieves dysmenorrhea, meaning a woman can survive menstrual period without pain and others unpleasant symptoms which cause her great discomfort. This is achieved due to the effect of tobacco on prostaglandins, which are the sources of dysmenorrhea. However, if you are looking for a way to get rid of unpleasant symptoms during menstruation, then it is better to simply take some kind of painkiller than to poison your body tobacco smoke.
• It does not form in the mammary glands and on the cervix malignant neoplasms during the period when a woman reaches menopause, because nicotine inhibits uncontrolled cell division.

In addition to the benefits of nicotine, it is also necessary to mention its harm to the health of a woman, especially one who is carrying a child under her heart. If a pregnant woman smokes excessively, then she is more likely to develop premature birth. In addition, a smoking mother runs the risk of giving birth to a sick baby.

5. The benefits of nicotine in stressful situations

Continuing to argue for the benefits of nicotine, doctors say that this substance helps a person cope with stressful situations in life. Every smoker knows that after smoking one or two cigarettes, the whole world seems kinder, nicer and happier. Why does this happen? This fact can be explained by certain physiological processes, occurring in the human body after the received dose of nicotine:

• breathing at the moment of smoking becomes rhythmic and balanced (all this helps the person to calm down);
• the smoke emanating from a cigarette relaxes the mind (especially if the smoker, while smoking, is accustomed to observing the smoke rings that form when he exhales);
• at the moment of inhaling a cigarette, provided there is complete silence around, a person completely relaxes;
• nicotine activates mediators responsible for the production of the “hormone of happiness” (which is why all smokers, in the event of any problem or unpleasant situation, experience a craving for smoking and immediately run around the corner to smoke a few cigarettes).

Note that the noticeable improvement in the smoker’s mood at the moment of inhaling is short-lived. After some time, apathy returns again, a desire arises to smoke a cigarette again in order to fall into a state of euphoria, which a person likes so much and helps him cope with numerous difficulties in life.

6. Nicotine will prevent allergies

Famous scientists of mankind provide several scientifically proven arguments regarding why nicotine is also useful. In their opinion, this substance reduces the likelihood of a person developing allergies, because at the moment of smoking even one cigarette, mastocytes (cells that play vital role when the body adapts to the effects of a number of allergens) begin to actively grow.

For example, in a person who smokes, allergic ailments such as urticaria or hay fever. Of course, a person who is prone to allergies cannot afford to escape from it by stocking up on thousands of cartons of cigarettes. This is too reckless and unreasonable action. In addition, do not forget that tobacco smoke itself can be an allergen. It is he who provokes the development of complicated diseases in humans. bronchopulmonary system eg asthma.

Nicotine: more benefit or harm?

Based on all that has been said about the benefits of nicotine, it must be said that everything is completely ambiguous on this issue. You can’t afford to believe only those doctors who are convinced that smoking can only cause harm to human health, but you shouldn’t follow the lead of scientists who give dubious arguments about why nicotine is useful. Just stop believing in stereotypes and understand that nicotine can be a dangerous substance for humans, because it enters the body along with carcinogenic tobacco smoke, but in some cases it can also be beneficial, but short-term.

Still, a smoking person absorbs not only nicotine and carcinogenic smoke, but also numerous dangerous substances that are part of it, and there are more than 400 of them. Naturally, they cause in the human body numerous factors, which lead to the development of life-threatening ailments, some of which become simply incompatible with life.

Nevertheless, knowing all this, many doctors are smokers, and heavy smokers. How can this fact be explained? We won't talk about how stressful the job is here. medical personnel. It’s just not a problem for doctors to find a “golden mean” in smoking, so that their bodies receive benefits from nicotine, and not just harm. They believe that if you smoke within “reasonable limits,” you don’t have to worry about ruining your health.

What does it mean, within “reasonable limits”:

• You cannot smoke more than 4 cigarettes per day (this applies to men of large build);
• Sick people and women, especially pregnant women, should not smoke more than 2 cigarettes per week.

We still want to urge you to the fact that smoking is a vice that needs to be gotten rid of urgently. Still, it does more harm than good. Your health will definitely suffer if you smoke constantly. It cannot be considered a miracle cure or a psychotropic drug. If you want to live a long time, not get sick, not constantly visit hospitals and others medical institutions, then you should definitely give up your smoking habit. This way you will not only save your life and protect your loved ones from carcinogenic smoke, which they will also have to breathe, but also save a lot cash to spend it on something more useful.
