The harmful effects of nicotine. Nicotine - what is it? The effect of nicotine on the body

(2 ratings, average: 5,00 out of 5)

Nicotine has a negative impact on human health. This fact is known to everyone, but not everyone knows how nicotine works and how dangerous it is. This substance is a strong poison. It affects all vital human organs and causes serious illness.

Nicotine is an alkaloid found in plants that belong to the nightshade family. The harm of nicotine is great; it slowly poisons the body. Most of this substance is found in tobacco leaves. Other plants contain it only in small doses. This substance is present in tomatoes, bell peppers, potatoes, and eggplants.

Nicotine is a powerful neurotoxin and is used as an insecticide; it can be used to poison insects. Is this carcinogen harmful to humans? How does nicotine affect your health?

Nicotine has an effect on the body. It enters through the mucous membranes of the mouth, when inhaled it ends up in the lungs, and nicotine can even be absorbed into the skin. Having penetrated the body, it acts quickly and begins to spread quite quickly with the bloodstream throughout all organs. Within seven seconds after inhalation, the poison reaches the brain. At the same time, a restructuring of the work of all internal organs occurs. A person experiences:

• increased blood pressure;
• increased heart rate;
• dilatation of cerebral vessels;
• increase in blood glucose levels;
• adrenaline is released into the blood.

The impact of nicotine on a person is expressed by physical and psychological addiction. It is very difficult for a smoker to quit a bad habit, since his body needs constant consumption of this harmful substance. Thus, the harm of nicotine is obvious.

Nicotine addiction

There is a toxic effect of nicotine on the human body. It affects receptors that release dopamine, the pleasure hormone, into the blood. A person experiences a surge of strength and energy, and the feeling of anxiety disappears. Subsequently, the addict begins to develop a need for such sensations. Such cravings have much in common with drug addiction.

Smoking addiction can develop even after the first cigarette. If a repeated portion does not enter the body, the person begins to experience internal discomfort. The harm of nicotine is expressed in the following symptoms:

• frequent headaches;
• feeling of restlessness and anxiety;
• nervousness and irritability;
• general weakness.

A fresh dose relieves discomfort and alleviates a person’s condition.

Cleansing the body

Nicotine has a negative effect on the body, but is eliminated from it fairly quickly. If there are no new intakes of this substance, then after three days the body will be cleared of it. But the toxic substances produced by cigarette smoke are very difficult to remove from the body. It will take decades to completely eliminate the harm of nicotine.

After a day, the poison is completely removed from the body. But breathing is restored only three days after the last cigarette has been smoked. Blood circulation can only return to normal after three months; in some cases it may take longer.

In addition to physical dependence, there is also psychological dependence. It's much more difficult to deal with. A person gets used to overcoming any stress or unpleasant event with the help of a cigarette, and it can be extremely difficult to get rid of it.

If you have the desire and willpower, you can get rid of nicotine addiction within three days. But the longer a smoker’s experience, the greater the health hazard that abrupt cessation of smoking poses. In this case there is a high risk heart attack. It is necessary to fight nicotine addiction, but this must be done gradually.

Harm to health

Nicotine is harmful; it affects all internal tissues and organs of a person. This carcinogenic substance has a negative effect on:

• brain;
• nervous system;
• heart;
• lungs;
• liver;
• vision.

In addition, nicotine increases the risk of developing cancer.

Under the influence of nicotine, the heart contracts much faster. During the day it is reduced by 15,000 times more than required by the norm. This load causes wear and tear on the heart muscle. Moreover, the risk of developing the following serious diseases increases:

• cardiac ischemia;
• angina pectoris;
• heart attack;
• atherosclerosis;
• aortic aneurysm;
• myocardial infarction.

The first sign indicating the presence of heart problems from smoking is the appearance of shortness of breath after physical activity. The harm of nicotine also affects the blood and makes it more viscous, which increases the risk of blood clots. Thus, the likelihood of a stroke or heart attack increases.

Nicotine has a negative effect on the lungs, as well as the mucous membranes of the throat and mouth. There is a high risk of developing atypical cells in the lung tissues, which can lead to cancer. The effect of nicotine on the respiratory system is expressed in inflammatory processes that develop in the bronchi and trachea, this can lead to emphysema - pathological expansion of the lungs. There is also a high risk of developing chronic bronchitis, lung cancer, tuberculosis, bronchial asthma.

Nicotine affects the brain and disrupts brain processes. People who smoke have problems with memory, thinking, and attention. The risk of developing atherosclerosis of cerebral vessels and intracerebral circulation increases. There is also a negative effect of nicotine on the nervous system.

From the outside gastrointestinal tract possible diseases such as:

• gastritis;
• stomach ulcer;
• duodenal ulcer.

The constant presence of nicotine in the blood leads to a decrease in the quality of vision.

Thus, the effects of nicotine on the human body lead to the destruction of internal organs and is the cause of many serious ailments.

Poisoning

The initial dose of nicotine can cause a response in the body. The person will experience vomiting and nausea. After a certain amount of time, the body will begin to adapt, and the unpleasant symptoms will go away.

Exceeding the daily dose of nicotine can have dire consequences. A person can become poisoned by this harmful substance. The lethal dose of nicotine is 40 to 80 mg at a time. The lethal dose is approximately 60 cigarettes smoked at once. In practice, already 30 cigarettes are characterized as a lethal dose.

Overdose is expressed by the following symptoms:

Exceeding the dosage has a paralytic effect on the human nervous system.

In most cases, nicotine intoxication occurs in people who do not smoke. So-called passive smokers, namely people who do not smoke, but who are in the same room with smokers for a long time, inhaling tobacco smoke, suffer much more. Children who are addicted to smoking and, trying to imitate adults, smoke a large number of cigarettes can become poisoned by nicotine.

Nicotine is dangerous; a person poisoned by this substance needs emergency help. You need to act immediately. First of all, it is necessary to take the patient to Fresh air or open the window.

The patient is given enterosorbents, this can be activated carbon or Smecta. The victim is advised to drink plenty of alkaline fluids. If the condition worsens, you need to call an ambulance.

In order to prevent emergency situations, it is important to know how nicotine affects the body and what dose is critical.

Nicotine and pregnancy

Children of smoking parents may have serious health problems at birth. Nicotine affects the baby’s body; the following diseases may begin to develop in the womb:

• heart disease;
• kidney disease;
• hearing problems.

A child born from a smoking mother has lower body weight and height than normal. Violations of this kind are associated with the fact that a smoking pregnant woman has problems with blood circulation. It leads to oxygen starvation the fetus, as a result of which the embryo develops poorly. Even after birth, such children will develop more slowly than their peers. They may experience problems with speech, attention, and memory.

All these facts speak in favor of the fact that a woman should not smoke during pregnancy. If you already have such a bad habit, you need to get rid of it gradually.

The effect of nicotine on the body is negative. In order to cleanse the body of poison, it is important to completely stop smoking. You can eliminate the consequences that this substance brings to the body with the help of proper nutrition, healthy lifestyle, sports. You need to know what harm nicotine can do to your body in order to take responsibility for your health and quit smoking.

Smoking is a habit that has long been firmly established in everyday life. modern man. Initially, tobacco, brought from the New World, was used as medicine. However, its harmful properties, after several decades, became more and more obvious to people.

Today everyone knows that the effect of nicotine on the human body (on the liver, lungs, brain, intestines, etc.) is definitely negative, even when using electronic cigarettes. But what exactly does it consist of? This needs to be sorted out.

Effects on the respiratory system

The most obvious and obvious harm cigarettes cause is the respiratory system. Yes, this can be seen from their “application”. A person, first of all, inhales the treasured nicotine smoke, and, accordingly, it goes on a “journey” through the respiratory system of a person (and, sometimes, a child). How exactly does breathing become harmful?

Impact principle

Smoke from cigarettes gets into the lungs, everyone knows this. There the following happens to him. Since it is much heavier than air, and the composition of cigarettes is quite rough, tar begins to settle in the lungs. And this is where the breathing problems are just beginning.

As they settle, nicotine tars block all existing lung self-cleaning mechanisms. This leads to serious damage to the alveolar sacs.

Associated diseases

Smoking significantly increases the occurrence of such unpleasant disease, like bronchiectasis. In essence, it consists of chronic expansion of the bronchi, as well as their sections. What is especially unpleasant is that this damage is irreversible. Their consequences can only be stopped, but not eliminated entirely.

Also, heavy smokers have a strong predisposition to various types allergies, asthma and colds. This occurs due to the fact that the smoke, while still on its way to the lungs, manages to greatly damage the mucous membrane of the larynx, trachea, and ciliated epithelium.

All of the above diseases take on much more severe and protracted forms, and it is much more difficult for smokers to recover from them. And as icing on the cake, there is an increased risk of lung cancer. Well, that's understandable. This organ is most susceptible to the effects of nicotine.

And modern cigarettes contain a lot of other substances that contribute to the breakdown or change of cells in the human body. Therefore, lung cancer here is a natural outcome, and not an unpleasant surprise.

Effects on the cardiovascular system

The cardiovascular system is affected by nicotine. Given the critical importance of the heart as a vital organ, it is difficult to overestimate the potential extent of harm that cigarettes can cause.

Accompanying illnesses

As a result of smoking, the production of adrenaline increases significantly. More precisely, the amount of substances that contribute to this, which are released into the body during the process, increases. Most often this leads to damage to the vascular wall and myocardium. Many people have unpleasant associations with the latter in the form of “myocardial infarction.”

Yes, cigarettes can lead to a similar unpleasant outcome. Doctors usually determine this by seeing atherosclerotic plaques on the coronary arteries.

Nicotine itself also contributes to the profuse formation of blood clots in circulatory system. And this, in turn, leads to a number of painful and deadly consequences.

At the “top” of this frightening “pyramid” are gangrene of the extremities and problems with the functioning of the heart (up to its stopping, due to a lack of incoming blood).

Statistical readings

Another point contributes to the wear and tear of the heart. Studies have shown that just one cigarette increases your heart rate by 8-10 beats per minute (hence the mild euphoria coupled with a false feeling of warmth).

Per day, this figure can be, in turn, from 15 to 25 thousand “extra” hits, thanks to the cigarettes smoked that day. And every day it becomes more and more difficult for the heart to maintain such a rhythm.

According to the disappointing statistics, and based on all of the above, it should not be surprising that diseases of cardio-vascular system affects smokers significantly more often than non-smokers.

In general, myocardial infarction and angina pectoris, along with other related diseases, are observed in “nicotine addicts” 10-12 times more often than in those who are free from this bad habit.

Impact on the reproductive system

To the displeasure of most men (and, unfortunately, teenagers), cigarettes also have a very negative impact on the reproductive system. Despite the outward “coolness” of this habit and its “help” in the matter of seduction, when it comes to bed, the smoker, in short, loses to the non-smoker on all fronts.

Harm to the health of smokers

In addition to the deterioration of sensitivity and “endurance” of the genital organs, there are deeper and more unpleasant consequences in this regard. The fact is that the glands involved in the reproduction process need a stable flow of oxygen. And nicotine tars significantly prevent this.

Also, the increased secretion of adrenaline caused by smoking impairs the functioning of all other secretory glands. All this affects the activity of the hormonal system, and, of course, causes significant damage to the reproductive organs.

There is one very unpleasant thing that statistics show. According to it, less than one fifth of all cases of male potency disorders are associated with mental or genetic problems.

All other cases are a consequence of long-term use of nicotine. 80%, to be somewhat accurate. A more than impressive figure that should be taken a closer look.

Harm to the embryo of a smoker

The most noticeable effect is on the reproductive system female body. Especially for offspring after conception. Yes, if a smoking man conceives, the fetus will be weakened. But he has a chance to survive and be born somewhat healthy.

But if during pregnancy you get to a cigarette expectant mother embryo - here the consequences in terms of the child’s heredity, as well as the rate of its growth and development, will be much more serious, even catastrophic. Yes and breast-feeding It will be unacceptable here.

Effect on the nervous system

One of the most noticeable effects that nicotine has on the body concerns the autonomic nervous system. Of course, it manifests itself most strongly in adulthood, after many years of regular and active smoking.

However, even at earlier stages, cigarettes have a certain negative impact on this most important component of the human body (especially if this is a teenager).

The problem is that nicotine, in addition to all its other negative properties, is also a neurotoxin. Accordingly, it has a fairly strong effect on how efficiently brain signals travel through the nervous system. This leads to worse reaction, irritability, and memory problems.

Impact principle

Now let's talk about how this effect occurs. It all starts with the fact that nicotine, after the lungs, goes straight to the brain. This journey through the blood vessels takes him about 7 seconds.

There, without exaggeration, this drug begins its effect, aimed at acetylcholine receptors (they are responsible for pleasure). First comes a pleasant excited state, which, over time, gives way to slight depression.

Reason for addiction

It is this last point that is the reason for such a strong addiction from such a seemingly “frivolous” drug. A person unconsciously (or even consciously) notices that while smoking, and for a short period of time after it, he feels good.

Good - in the full sense of the word. And without a cigarette it’s bad. Therefore, he reaches for the coveted “pacifier” again and again, turning psychological dependence into physical one.

Combination of nicotine and alcohol

The most dangerous point is that smokers, over time, no longer have enough of just cigarettes to maintain their high spirits. Therefore, they supplement it with another “household” drug - alcohol.

The combined effect of alcohol and nicotine on the human body can be simply catastrophic. Alcohol speeds up blood flow, and, accordingly, the spread of nicotine throughout the body. In addition, it further slows down the rate at which signals are transmitted from the brain to the body.

Harm to organs

For example, nicotine reaches the lungs with the help of alcohol through the vessels just like “on a skid” and can be more effectively absorbed by the walls of this long-suffering organ (and also, of course, to the liver). The heart, being often exposed to doses of alcoholic beverages, begins to become overgrown with fat.

Coupled with the blood clots formed by nicotine, this puts a colossal load on the main blood pump of the human body. Moreover, if this is not an adult, but a teenager, then the degree of destructive impact increases exponentially.

Well, there’s nothing to say about the effect of such a combination on the brain and its vessels. Slowing down the passage of signals, the death of brain cells due to oxygen deficiency, the formation of blood clots in the brain - all this is unlikely to have any effect positive influence on the state of the nervous system.

Related diseases and problems

As a result, when nicotine and alcohol are used together, a person is much more likely to be at risk for the following diseases:

• asthma;
• hypertension;
• coronary insufficiency;
• frequent headaches;
• stroke;
• sclerosis.

Of course, thanks to alcohol, both the liver and the stomach are damaged, affecting the entire digestive system along the way. And here everything is a little worse than it seems.

Alcohol also brings with it nicotine, which also contributes to this dirty deed. The result is unfavorable for the health of all these organs, liver, intestines, skin, vision, etc.

Conclusion

Considering all of the above, one can only wonder why millions of people in the world still remain susceptible to the harmful habit of smoking. However, a huge production and advertising machine works in favor of cigarettes, which, together, create such a seductive image of a successful and “cool” smoking person.

How does NICOTINE work? Experiment and overdose. Effects and Consequences

How does smoking affect the human body?

The effect of alcohol and nicotine on human health

How smoking affects thinking and brain function

As can be seen from the above, the reality for health is somewhat darker, and the matter will not be limited to headaches with pressure and shortness of breath.

Precisely as a process, a kind of ritual, a psychological action, because there is no benefit here. So, entering the lungs along with smoke, nicotine is absorbed into the alveoli and capillaries, where the process of gas exchange occurs. The next destination is the smoker's blood, which brings it to the brain.

Studies aimed at finding out the effect of nicotine on the human body have shown that this harmful substance most affects the respiratory, digestive, cardiovascular and nervous systems. When the neuron first came into contact with nicotine, the nerve reacted aggressively to the stimulus, for which it needed much less energy ( electric current) than usual - the body resisted.

Subsequent contacts caused habituation of the nerve, and subsequently a “demand” to return the stimulus nicotine. This is precisely the principle of the body’s adaptation to this poison.

Nicotine can also replace (short-term) the natural release of endorphin (the pleasure hormone), while the natural production of the hormone slows down and subsequently stops altogether.

It takes only 8 seconds for nicotine to travel from the alveoli to the brain. The CNS (central nervous system) reacts to this poison as follows: acetylcholinergic receptors, under the influence of an irritant, change the functioning of all body systems. As a result, blood pressure rises, heart rate increases, blood vessels in the periphery narrow, and in the brain, on the contrary, they expand. Adrenaline is released into the blood, and at the same time glucose levels increase.

The body spends a certain amount of energy on all these reactions, therefore, even without doing physical exercise, a smoker does not gain weight. But this is not the health-improving effect that sports, for example, brings. In this case, the result will most likely be negative. Due to the release of adrenaline and the release of endorphins, the smoker feels euphoria, clarity, increased mood and strength. But a maximum of half an hour passes, all of the above effects fade, and the body requires a dose of pleasure.

Nicotine causes both physical and mental dependence.

Physical dependence

The body gets used to the supply of nicotine and begins to require it in case of prolonged absence (akin to drug addiction). When you give up cigarettes, the so-called “withdrawal” begins: performance decreases, interruptions in heart function are observed, and depressive states occur, accompanied by headaches. But this, as they say, is only one side of the coin. If physical addiction were the only one, it could easily be overcome. For example, using nicotine-like drugs.

Mental dependence

This addiction is much more complex and harder to overcome. Smoking, as mentioned above, is a kind of rite, a kind of ritual, which, subsequently, is extremely difficult for a person to do without. Someone smokes while waiting for transport at a bus stop, someone whiles away the time with a cup of coffee, with friends, while talking. You never know, each person has their own habits. And since habit is second nature, you have to fight it very hard and persistently.

To change your habits, you need to change yourself, your stereotypes, your worldview. Such withdrawal is much more serious than physical need. Medicines are powerless here; a strong-willed decision is necessary. And without the consent of the smoker himself, without his firm intention, nothing will happen.

Effect on the body

Smoking harms the digestive system. But before that, the blow falls on the teeth, mucous membranes of the mouth, nose and larynx. Due to temperature changes, tooth enamel is destroyed. The yellow color occurs because tobacco tar settles in the cracks formed, which in addition to its color has a specific odor. Dissolving in saliva, nicotine enters the stomach, where it irritates the mucous membrane of the stomach, and then the mucous membrane of the duodenum. This leads to pain, ulcers, and gastritis.

Harmful substances contained in tobacco (acids, ammonia, particulate matter, pyridine bases) irritate the lining of the lungs. Ammonia ( ammonia) can contribute to the development of non-febrile bronchitis, and this, in turn, significantly increases the risk of developing tuberculosis. Tobacco tar, which settles on the walls of the mucous membrane, interferes with gas exchange and oxygen enrichment.

The heart of a smoker makes 15 thousand more contractions per day than the heart of a person who does not have this addiction. Such a load leads to wear and tear of the heart muscle, firstly, and secondly, working at an increased rate, the heart does not receive enough oxygen that is required under this load. Why? The vessels are narrowed, spasmed, and blood flow is hampered. The second reason is that instead of carrying oxygen, hemoglobin “carries” carbon monoxide.

All these factors lead to the development of coronary heart disease, angina pectoris, and heart attack. Hypertonic disease- a frequent guest of a smoker, in addition, it is often complicated by hypertensive crises. This leads to impaired cerebral circulation, and subsequently to a stroke.

A disease such as obliterating endarteritis (damage to the vascular system of the legs) is a consequence of smoking, since it practically does not occur in non-smokers. The most severe form of this disease is the occurrence of gangrene.

Nicotine affects the condition of the skin, making it yellow and wrinkled. The fingers take on a yellowish-brown tint. There is a cough and shortness of breath. For men, smoking is fraught with impotence.

It is worth noting that smoking in school age directly affects student performance. If a student smokes, his mental and physical development slows down. Since depression is not uncommon when smoking, young people lose the desire to develop and learn anything, and it is more difficult for them to decide on the choice of activities to their liking. Such teenagers are more “excited” and nervous, they experience memory deterioration, and they think slower.

Passive smoking is also unsafe. In this case, there is a significant risk of developing lung cancer, as well as acquiring other diseases associated with the respiratory system. If one spouse smokes in a family, the other has a 30% increased risk of developing cancer.

The influence of nicotine on the body of a pregnant woman is fraught with all sorts of pathologies and abnormalities in the unborn child. In such mothers, children are born prematurely, there is a high risk of miscarriage or fetal death, and the death of the child in the first year of life. Children of smokers often lag behind in physical and mental development.

To smoke or not to smoke? Of course, this is a personal matter for everyone, but anyone sensible person choose a healthy lifestyle without cigarettes.

And lungs. Those who abuse this bad habit quickly deteriorate their teeth, and their face begins to acquire a yellowish color. But many people don't think about how smoking affects the liver.

How does smoking affect liver function?

The negative effect of cigarette smoke on this organ occurs due to the fact that all metabolic processes - the processing of a large number of different substances, including nicotine, occur in the liver. When you inhale a cigarette, the smoke enters the respiratory system and is immediately absorbed into the blood, and it contains slightly less than 4 thousand different substances. The liver must process all these components, and they must become safe for the entire human body.

The effect of smoking on the liver cannot be underestimated. She, neutralizing the chemicals found in tobacco smoke, suffers greatly. In addition, all organs are negatively affected. The bottom line is that when hepatocytes process nicotine and tar, other harmful substances are absorbed into the blood. They affect other organs and can provoke many diseases, disrupt metabolic processes, and at best simply lead to poor health.

Harmful effects of nicotine and tobacco smoke on the liver

After nicotine enters the liver, it is processed by hepatocytes into cotinine (an alkaloid) that is harmless to the body. But for this process to occur, it must release a large amount of cytochrome P450 (enzyme). The problem is that the liver can produce it only in strictly limited quantities, and it is also required for normal hormone metabolism and the removal of endogenous toxins.

Tobacco smoke consists of the following substances:

• Nicotine (is an alkaloid poison).
• Polonium, lead and radium (radioactive nuclides).
• Substances that enhance taste (substitutes for tastes and smells created synthetically).
• Carbon monoxide.
• Resin.
• Ammonia.
• Tar.
• Benzene.
• Butane.
• Cadmium.
• Turpentine.
• Propylene glycol.
• Benzopyrene.
• Arsenic.

All these substances are carcinogenic and very toxic. They are much more harmful than car exhaust fumes, and you can imagine how dangerous the effect of smoking is on the liver.

Smoke from cigarettes affects this organ in such a way that the production of enzymes is reduced significantly and this leads to metabolic disorders, deterioration of metabolism, sex hormones begin to be poorly produced and the functioning of the gastrointestinal tract is disrupted. Plus, smokers have problems associated with the functioning of the cardiovascular system and weakened immunity.

These harmful chemical components act on the liver of a person who smokes cigarettes so much that even powerful medications become practically powerless in the fight against them. The problem lies not in the drugs themselves, but in the fact that the smoker’s liver does not produce enough enzymes to process the tablets and they simply enter the intestines undigested and do not provide any benefit.

Nicotine not only affects the liver directly. It constricts the blood vessels, causing less blood to flow into the organ and preventing it from working as well as it should.

The effects of smoking on the liver

In people who suffer from this addiction, the liver cannot fully cleanse the blood of various toxic substances that enter the human body along with food, water and air. The liver weakens and cannot fully perform the following functions:

• Neutralize toxins entering the blood.
• Fight chronic diseases.
• Neutralize fat levels with the help of cholesterol produced.
• Fight carcinogenic substances.
• Problems with blood vessels appear.

For most smokers who like to occasionally drink beer, or even something stronger, eat fatty and smoked foods, as well as those who live in industrial urban areas, on average, after 10 or 15 years of such a life, the liver “regenerates.” Hepatocytes, which were absolutely healthy, begin to be replaced by adipose tissue, vascular sclerosis appears and many toxins enter the blood.

Enzymes and hormones that the liver must produce in large quantities, as well as glucose, are produced less and less. The result of all these processes is disappointing. The functioning of the entire circulatory and digestive system is disrupted, due to the fact that it is this organ that produces the synthesis of thrombopoietin and hepcidin. Thanks to the first, platelet synthesis is regulated in bone marrow, and hepcidin is responsible for the synthesis of iron homeostasis in the human body.

Why does nicotine addiction occur and what is the role of the liver?

Many people think that this organ has nothing to do with nicotine addiction, but this is not so. Nicotine is a necessary substance for humans, but only in small quantities. The liver has a function that allows it to produce this substance and, most importantly, it is completely harmless. But it should be noted that the nicotine produced by the liver is not the same as that in cigarette smoke. When smoking a cigarette, smokers have an excess of this substance and the body stops producing it. This is why it is so difficult to quit smoking.

People need to get a certain dose of nicotine, but after abruptly quitting the habit, especially if the person has been smoking for a large number of years, it stops being produced. This is why there is such a strong dependence on cigarettes. But if you abstain from smoking for a while, the liver will resume producing nicotine and the dependence on tobacco smoke will disappear.

Even those who are not addicted to smoking cigarettes, when surrounded by them, inhale tobacco smoke, and the liver produces the necessary enzymes so that the body can cleanse itself and remove toxic substances in the urine. In people who smoke, the enzyme that is responsible for removing nicotine from the human body is produced in ever larger quantities, and nicotine is eliminated faster and faster. This may seem good to some, but, oddly enough, this is what causes addiction to tobacco smoke. This is because nicotine is removed so quickly that the body begins to require its replenishment much faster. Smoking and a healthy liver are incompatible.

If a person whose liver function is impaired completely stops smoking, as well as drinking alcohol, the liver will begin to recover. Before you start smoking, you should first think carefully about whether this addiction is worth subjecting your liver to such tests.

Smoking has become a big problem nowadays. Everyone knows that it is harmful, yet many continue to smoke. Nicotine contained in cigarettes, even in small doses, has a detrimental effect on the body. The problem is that not everyone understands what nicotine is and exactly how it affects human health. Let's look into this issue!

general characteristics

So nicotine is an alkaloid found in plants of the nightshade family. The largest amount of this substance is found in tobacco, but there are 66 other crops that contain it to a lesser extent. Nicotine is found in small quantities even in vegetables such as tomatoes, bell peppers, potatoes and eggplant.

In dry tobacco, nicotine can range from 0.3 to 5% by weight. Its biosynthesis occurs in the roots, and accumulation occurs in the leaves. Nicotine is a colorless, oily liquid. It boils at a temperature of 247.6 °C and darkens very quickly when exposed to air. At temperatures of 60-210 °C, nicotine is partially dissolved in water. And at temperatures below 60 and above 210 °C it mixes well with water.

The name "nicotine" appeared in honor of Jean Nicot, who was the French ambassador to the Portuguese court. In 1560, he sent Queen Catherine de Medici some tobacco as a remedy for migraines. In addition to migraines, they treated rheumatism, asthma, toothache and wounds.

Nicotine and humanity

Many will ask: “Why smoke it?” The fact is that smoking is not only an addiction to nicotine, but also a habit of keeping oneself busy with something. Therefore, for those who cannot quit this crap just like that, you can do it smoothly by replacing a simple cigarette with an electronic one.

Conclusion

So, we are once again convinced that smoking causes irreparable harm. But besides nicotine, cigarettes also contain a lot of harmful substances. Therefore, it is better to learn to please yourself with other things and depend on something more pleasant, for example, on love, as in the song “Former Nicotine.” We wish you good health!
