Lethal dose of nicotine in mg

The lethal dose of nicotine for humans is 0.5 – 1.0 mg per 1 kg of body weight.

But these data are approximate, take into account many related factors - the person’s age, smoking experience, individual sensitivity to nicotine, health status, consumption of alcohol, food, medications.

The body of a teenager is more sensitive, and the lethal dose for a young person will be 10–20 mg. The body of a long-term smoker has adapted to the regular supply of small doses of nicotine, and such a smoker will survive ingestion of more than 100 mg of nicotine.

In 2013, Austrian scientist Bernd Mayer published his calculations, in which the lethal dose of nicotine is 500 – 1000 mg. The difference of opinion arises because it is impossible to introduce a lethal dose of nicotine into the body, and all lethal doses are calculated in the laboratory.

Toxicology textbooks indicate a lethal dose in the range of 10–80 mg, and all calculations for restricting the sale of nicotine and nicotine-containing products are based on these data.

Test for smokers

How much does a person need to smoke before he dies?

How many cigarettes do you need to smoke to die? The nicotine content in 1 cigarette varies and depends on the brand. On the side of the cigarette pack there is information about the amount of mg of nicotine. The indicator can be from 0.3 mg to 1.3 mg of nicotine in 1 cigarette.

On average, 1 cigarette contains 1 mg of nicotine. Considering a lethal dose of nicotine of 0.5 - 1.0 mg, let's calculate how much it takes to smoke to die. For a person with a body weight of 70 kg, the minimum of cigarettes is life-threatening - 35, maximum - 70.

A person weighing 55 kg will need from 27 to 55 cigarettes to die, and a person weighing 100 kg will need from 50 to 100, respectively. At the same time, a person must smoke them in a short period of time.

Contrary to all calculations, if a person weighing 70 kg smokes 70 cigarettes, he will not die. This is due to the lower nicotine content in tobacco smoke - only 30%.

In this case, an even smaller amount of nicotine will enter the blood, and the person will have time to exhale the rest. Formaldehyde will destroy some of the nicotine. And the smoker’s body, which receives small doses of nicotine, gets used to it over several years.

When smoking a large number of cigarettes, symptoms of acute poisoning will occur, the person will stop smoking and, as a result, the body will not receive a lethal dose.

Cases of death have been described when smoking just 2-3 cigarettes. Nicotine had a toxic effect on the nerve centers, cardiac and respiratory arrest occurred, which led to death.

How many die, mortality or statistics of deaths from smoking

More than a billion people in the world regularly use tobacco. This is about 20% of the world's population. Only active smokers are taken into account.

Although tobacco smoke contributes to the development of the same diseases in both active and passive smokers. Every year, 3 to 5 million people die from diseases caused by regular smoking.

Of these, 600 thousand people are passive smokers. The life expectancy of a smoker in a developed country is reduced by at least 10 to 13 years.

The mortality rate among smokers, compared to their non-smoking compatriots, is 30–80% higher. The indicator increases with the number of cigarettes smoked and smoking experience. Every second person dies from a disease caused by smoking. 90% of people who die get sick as a result of regular tobacco use.

At the same time, the number of people who smoke in the world continues to increase every year. If this continues, by 2030 more than 10 million people will die every year from diseases caused by smoking.

In Russia, approximately 1,000 people die from tobacco every day.

Effects of nicotine and cigarettes on the body

Nicotine from tobacco smoke enters the lungs, from where it is absorbed into the blood. Within 7 seconds, nicotine will reach the brain. As a result, brain activity is inhibited, reactions slow down, intelligence decreases, and sleep is disturbed.

Nicotine causes an increase in blood pressure and increased heart rate, narrowing of blood vessels, the development of atherosclerosis, which helps in the formation of blood clots, the occurrence of angina pectoris, and myocardial infarction. In addition to atherosclerosis, nicotine provokes the development of obliterating endarteritis.

These diseases cause disruption of the blood supply to tissues and organs and are the main causes of limb amputation. When exposed to nicotine, the blood supply to the eyes is disrupted, the optic nerve is affected, which leads to decreased vision and blindness. The innervation of the hearing aid is disrupted, resulting in decreased hearing.

Smoking is the main provoking factor in the development of lung cancer and chronic obstructive pulmonary disease. When swallowing saliva containing nicotine breakdown products, cancer of the gastrointestinal tract occurs.

Smoking causes irreparable harm to the female body, causing ovarian diseases, which is dangerous due to infertility, miscarriage, and the birth of a child with various pathologies. Nicotine has a negative effect on a person’s appearance, worsening the condition of the skin and teeth.

Symptoms of acute nicotine poisoning

Ingestion of significant doses of nicotine into the body leads to nicotine intoxication, which consists of a functional disruption of the cardiovascular, respiratory, and nervous systems and is manifested by the following symptoms:

Tobacco;
Headache, dizziness, tinnitus;
Weakness, pallor, cold and sticky sweat;
Cyanosis of the nasolabial triangle, difficulty breathing;
Increased salivation, nausea, vomiting, diarrhea;
Increased blood pressure, tachycardia - pulse up to 180 beats per minute or more;
Unsteadiness of gait, trembling of limbs, blurred speech.

These symptoms are observed in the first stage of poisoning. And when assistance is provided, they soon pass.

The second stage of poisoning occurs after 1.5 - 2 hours when a large amount of nicotine enters the body at one time and the victim is not provided assistance. The onset of the second stage is due to the fact that nicotine first has an exciting effect on the intermediate ganglia of the autonomic nervous system, and then paralyzes them.

Loss of consciousness occurs, even to the point of coma, breathing becomes shallow and irregular, blood pressure decreases, the pulse becomes rare - up to 20 beats per minute.

Convulsions, epileptic seizures, and respiratory and cardiac arrest may occur. Which, if medical care is not provided in a timely manner, leads to death.

There are many dangerous things in the world that can kill a person. Unfortunately, people agree to many of them voluntarily. People consciously sign their sentence, especially when it comes to tobacco products. A lethal dose of nicotine has been recorded, the amount required to cause death. But how can you recognize it to protect your life? It turns out that everything is quite simple. They have been interested in this question for a long time, and scientists decided to move on to numbers. After a series of studies, they were able to find out what dose of nicotine is fatal to humans. Now everyone can find out the dangerous number.

Lethal dose of nicotine in cigarettes

Any tobacco-containing product contains many harmful poisons. Once inside, they begin their destructive function. Nicotine, an alkaloid obtained from tobacco leaves, is especially dangerous. It not only causes persistent addiction, but is also considered the most toxic.

When wondering what a lethal dose of nicotine is, it is worth knowing about certain factors. Using them, you can calculate how many cigarettes a person can smoke without fear for his own life:

body weight;
physiological characteristics;
dose of nicotine.

A number of experiments have proven that to achieve death, it is enough to have a concentration of 0.5-1 ml of nicotine per 1 kg of weight in the body. Going into numbers, we can give a clear example. A person weighing 70 kg who smokes cigars containing 1 ml of nicotine needs about 40 cigarettes at a time. Sometimes the lethal dose of nicotine can change due to various factors. For example, medications make things worse. If a person smokes during treatment, the lethal dose of nicotine changes its parameters. To achieve a lethal outcome, you need less of it. This is why it is so dangerous to abuse bad habits during therapeutic therapy.

Knowing what a lethal dose of nicotine is and continuing to be friends with “smoking pipes” is wrong. It is worth realizing that destructive poisons accumulate gradually, and it is impossible to avoid the negative impact.

A lethal dose of nicotine for humans or the terrible truth

It turns out that death due to nicotine intoxication is rare. It's not that people know how much they can smoke without fear for their lives. The reason lies in completely different factors:

The smoker consumes only a third of the toxic substance, the rest is burned;
When you inhale smoke, most of it is absorbed into the blood;
The body's protective function is triggered; people physically cannot smoke a lot. They experience nausea and vomiting;
Gradually, the body becomes accustomed to poisons and they become less dangerous.

But this does not mean at all that you don’t need to quit. Nicotine can disrupt or even stop the heart. Therefore, at the slightest tingling in the chest area, you should consult a doctor, and most importantly, give up the bad habit.

Lethal dose of nicotine for humans: statistics

The statistics are not encouraging at all. Approximately a billion people are addicted to addiction. Approximately 20% of the world's people are active smokers. But diseases can develop even in passive people. About 5 million citizens die every day due to cigarettes. Even the life expectancy of smokers is reduced by 12-15 years.

There are a huge number of fatal diseases, 90% of unfortunate people become victims of lung cancer. The sad news is the growing dynamics of addicts. Their number is increasing, and most importantly, the age of the patients. Relatively recently, this was a problem for the middle-aged population, but today even teenagers are at risk.

Diseases of the respiratory tract, stomach, and oral cavity are the most minimal consequences. We must not forget about cancerous tumors. As for women, they need to be wary of deterioration of hair, skin, infertility and the possibility of frequent miscarriages. It is difficult to give birth to a healthy child with a high smoking history.

It is important to notice the signs of intoxication with harmful substances in time. It is usually accompanied by unpleasant symptoms:

strong odor from the mouth;
severe headache;
fatigue;
cold sweat;
hard breath;
diarrhea;
vomit;
excessive salivation;
increase in pressure.

These are all first signs and cannot be ignored. Timely provision of assistance will help prevent dire consequences. After all, if you leave what is happening unattended, the next stage of poisoning may occur: convulsions, epilepsy, respiratory arrest, coma.

Giving help

If you witness poisoning from tobacco products, you need to provide first aid to the victim before doctors arrive. Perhaps these actions will help save lives:

Call an ambulance.
Lay the patient on his side.
In case of vomiting, clear his airways.
Provide oxygen access.
If there is no vomiting, drink water.
If the victim is conscious, give him water and activated carbon.
Provide cardiopulmonary resuscitation if necessary.
Wait for the doctors to arrive.

The concept of what dose can become fatal is difficult to answer. Each body is individual, you can’t take risks or joke with your health. It is best to take care of a normal future and quit your addiction forever.

Nicotine toxicity
Nicotine is a strong poison, comparable in toxicity to cyanide. It is currently believed that the dose of nicotine that can lead to human death is 0.5-1 milligrams per kilogram of weight.

The lethal dose of nicotine, that is, the dose that can lead to the death of a person, is 0.5-1 milligrams per kilogram of weight

A person consumes nicotine not only through smoking, but also through snuff and chewing tobacco. Let's consider these options separately.

Cigarettes
Let's take cigarettes containing 1 mg of nicotine. For a smoker weighing 50 kilograms, the minimum dangerous number of cigarettes will be 25 pieces, the maximum – 50. Accordingly, for a person weighing 70 kilograms, this amount will be 35 and 70 cigarettes. Cigarettes containing 3 mg of nicotine reduce the numbers by three times, and for the first case the number will be 9 and 17 cigarettes, for the second - 12 and 23 cigarettes, respectively. The higher the concentration of nicotine in cigarettes, the fewer cigarettes you can smoke at once without the risk of death.

Accordingly, for a person weighing 70 kilograms this amount will be 35 and 70 cigarettes

This indicator depends on many related factors, such as a person’s age, general health, and individual tolerance to nicotine. Alcohol or medication intake may play a role, as can whether the smoker is full or smokes on an empty stomach.

However, deaths from poisoning due to smoking are extremely rare. Why? It's simple.

During smoking, part of the nicotine is burned, and only a third of this substance remains in cigarette smoke.
The nicotine that remains in the smoke after combustion is also not completely absorbed into the blood; part of it remains in the exhaled smoke.
Nicotine concentration is reduced by formaldehyde contained in cigarette smoke.
It is simply impossible to smoke a lethal number of cigarettes at once. Even if a person smokes cigarettes one after another, he will most likely get nicotine poisoning, experience nausea, sometimes vomiting, and will not be able to continue.
Thus, dying from nicotine poisoning through smoking is almost impossible.

Chewing tobacco
In the process of chewing tobacco, much more nicotine enters the body than with tobacco smoke, since the concentration of nicotine in it is several times higher than that of cigarettes, and there are no factors that reduce its level, as with smoking. Thus, if a serving of chewing tobacco contains 5 mg of nicotine, then for a person weighing 50 kg, consuming 5-10 servings at a time can be fatal.

For a person weighing 50 kg, consuming 5-10 servings at a time can be fatal.

Accidental or intentional ingestion of tobacco is especially dangerous. An adult is at risk of severe poisoning, and for a small child, swallowing even half a cigarette can result in death. Parents, be careful!

New calculations of the lethal dose of nicotine
Bernd Mayer, an Austrian scientist, published his research data, which states that the lethal dose of nicotine for humans is 0.5 grams. In his research, Mayer relied on known cases of nicotine-related deaths and evidence of human tolerance to much higher doses than those claimed to be lethal. According to Mayer, by comparing the generally accepted lethal dose of nicotine with documented cases of deaths from nicotine poisoning, we can conclude that the lethal dose of nicotine is much higher.

For humans, the lethal dose of nicotine is 0.5 grams (c) Mayer's research.

By the way, if you remember about the notorious horse that died from a drop of nicotine, and take this drop as equal to one gram, then, according to new research, half of this very “horse” dose will kill a person.

Nicotine is found in tobacco products and is a dangerous toxin. An overdose can lead to acute poisoning. Many people have heard that nicotine is a poison that can be fatal in large quantities. For consumers of tobacco products, the question of the lethal dose of this toxin and the number of cigarettes containing it is relevant. The answer will be given below.

Cigarette toxicity

Nicotine is a plant alkaloid, which, in addition to tobacco leaves, is found in nightshades. In its pure form it is a dark liquid with a characteristic aroma and a pungent taste.

In terms of toxicity, it is comparable to cyanide class poisons. Exceeding its dosage leads to severe intoxication and death.

Lethal dose of nicotine

The amount of toxin that can cause death is considered to be 0.5-1 mg per 1 kilogram of human weight.

These figures are approximate and depend on:

For an adult

Depending on body weight, the amount of nicotine that can become life-threatening can vary in dose:

with a weight of 45 kg – 22.5-45 mg;
55 kg – 27.5-55 mg;
65 kg – 32.5-65 mg;
75 kg – 37.5-75 mg;
5 kg – 42.5-85 mg;
95 kg – 47.5-95 mg.

For a teenager

A young body is more susceptible to nicotine, and a lethal dosage for a teenager may be 10-20 milligrams of the toxin. But ingestion of up to 70 mg is considered lethal.

How many cigarettes is considered a lethal dose?

Nicotine content in 1 cigarette, mg	Weight 55 kg		Weight 75 kg		Weight 95 kg
Nicotine content in 1 cigarette, mg	Minimum (pieces)	Maximum (pieces)	Minimum (pieces)	Maximum (pieces)	Minimum (pieces)	Maximum (pieces)
0,3	92	184	125	250	158	316
0,4	69	138	94	188	119	238
0,5	55	110	75	150	95	190
0,6	46	92	63	125	79	158
0,7	39	79	53	107	68	136
0,8	34	69	47	94	59	118
0,9	30	61	42	84	53	106
1	27	55	38	75	48	96
1,1	25	50	34	68	43	86
1,2	23	46	31	62	40	80
1,3	21	42	29	58	37	73

To obtain a lethal dosage of tobacco poison, it is necessary to smoke the specified amount without interruption, one after another, which in practice happens quite rarely. For acute poisoning, much less is required. This amount depends on your health status and other factors.

If you eat a cigarette, the amount of nicotine entering the body will be much greater. A few swallowed pieces can kill even an adult, so tobacco products should be kept away from small children.

Cigarette smoke contains more than 4,000 different compounds, many of which are quite toxic. All of them worsen health and sometimes lead to death.

Cigarettes are not the only source of a dangerous substance. Other tobacco products also contain nicotine:

cigar – 15-100 mg;
snuff – 12-15 mg/g dry and 5-30 mg/g moist;
chewing tobacco – 2-8 mg;
Nicorette chewing gum – 2-4 mg per plate.

Dangerous and fatal diseases of smokers, statistics

Smoking has a detrimental effect on human health due to the huge amount of toxic substances contained in smoke. They can provoke a number of diseases, sometimes incompatible with life.

Diseases

Smoking reduces life expectancy by more than 10 years. Toxic substances in smoke lead to damage to almost all body systems.

Typical diseases of the respiratory structures:

The harmful effects of smoking also affect the digestive system. A person may develop:

chronic gastritis (subsequently there is a high probability of stomach cancer);
malignant tumors of the esophagus;
pancreas cancer;
chronic inflammation of the large intestine, which can lead to cancer and other formations.

A long history of tobacco smoking leads to the most dangerous pathologies of the cardiovascular system, and many begin to manifest themselves from the age of 30.

Diseases that are typical for smokers:

A smoker's genitourinary system is also at risk. The following diseases may occur:

malignant tumor of the bladder;
decreased potency in men and decreased sperm viability, impotence;
infertility;
cervical cancer;
congenital pathologies in children of smoking women.

The list of characteristic diseases of tobacco product consumers can be expanded almost endlessly. In addition to the above, it is worth mentioning such pathologies as:

Mortality statistics

The mortality rate among smokers in middle age is noticeably higher than among other people. And the likelihood of death increases with experience.

Every 6 seconds, one person dies in the world due to diseases caused by smoking, and every 9 seconds - one in Russia.

In the Russian Federation, 17% of all deaths are related to smoking.

According to statistics, the mortality rate among tobacco-dependent people is higher than that of drug addicts and alcoholics, and amounts to about half a million people a year.

Among deaths from cancer, 22% occur among smokers. Of these, in Russia, 52.1% of all cancers in men and 5.2% in women are associated with tobacco consumption.

More than 80% of deaths from coronary heart disease among smoking men aged 35-44 years and 27% over 45 years old, 62% among women.

The average age of those who die from heart attacks is 67 years, for tobacco-dependent people - 47.

75% of deaths from myocardial infarction also occur among those who like to tar. Passive smoking causes death in 15% of people.

Timely relief from destructive addiction is the only universal way to prevent dangerous diseases. After quitting smoking, harmful components will gradually be eliminated from the body, which will lead to improved health and prolongation of life.

Causes of nicotine poisoning

Nicotine toxicity can occur for many reasons. It is a particularly dangerous critical condition requiring immediate medical intervention.

Nicotine is an alkaloid that is found in large quantities in tobacco, the basis of cigarettes. It is also found in small, non-hazardous quantities in tomatoes, potatoes, and sweet bell peppers. Recently, nicotine has been added to e-cigarette liquids, which are used by people who want to quit smoking.

The lethal dose of nicotine for a person varies from person to person, on average it is 40-80 mg. For children, pregnant women, and elderly people it is much less.

Below are the main reasons that can cause acute nicotine poisoning.

Acute cigarette poisoning in non-smokers develops when they try to start smoking. Most often this happens during drinking and intoxication. A person whose body is not accustomed to daily nicotine intoxication can be poisoned by several strong cigarettes.
Poisoning from an electronic cigarette is possible when using low-quality and counterfeit smoking liquids.
Staying in a smoky room for a long time. With passive inhalation of tobacco smoke, signs of nicotine overdose may develop.
Nicotine overdose can develop in smokers if they smoke several packs of cigarettes in a short period of time.

Please note that a person who smokes more than a pack of cigarettes daily has chronic nicotine poisoning. This condition does not manifest itself with pronounced symptoms, but is a dangerous condition for humans, which gradually kills the body.

Symptoms and signs of acute nicotine poisoning

Acute nicotine poisoning develops when receiving a large dose of nicotine in a short period of time. The person quickly develops a severe headache and nausea. The state of excitement alternates with inhibition.

Below are the main signs of human nicotine poisoning.

Acute and severe headache accompanied by dizziness.
Pale skin, blue lips and visible mucous membranes develop due to lack of oxygen and acute hypoxia.
Nausea and vomiting are symptoms of acute intoxication of the body. Due to tobacco smoke intoxication and hypoxia, brain tissue suffers from a lack of oxygen and nutrients. When the vomiting center is damaged and intracranial pressure rises, vomiting of central origin develops. Vomiting attacks can develop without previous nausea. Such vomiting does not bring relief or improvement in well-being.
Loss of coordination. A poisoned person's gait is disturbed and he may drift to the side. Tremor also develops - trembling of the arms and legs, which affects fine motor skills.
Change in breathing. The patient begins to breathe quickly and shallowly. Respiration rate exceeds 20 per minute. In severe cases, acute respiratory failure develops.
Hyperhidrosis (excessive sweating), hypersalivation (increased salivation), lacrimation.
Convulsive attacks (as in epilepsy).
Profuse diarrhea, which occurs due to severe intoxication syndrome.

Please note that if the body simultaneously receives extremely large doses of nicotine, a disturbance of consciousness may occur, in which the patient is loaded into a deep coma.

What happens to the body during chronic nicotine poisoning

Chronic poisoning gradually develops in people who smoke. The rate at which symptoms increase depends on the number of cigarettes smoked per day. If a person is used to smoking more than a pack a day, poisoning can develop quite quickly. With chronic nicotine intoxication, the following pathological processes in the body are observed:

chronic conjunctivitis. A person complains of constant lacrimation, redness of the conjunctiva, and discharge of purulent exudate from the eyes. It is also possible to feel a burning sensation and dryness in the eyes, especially after prolonged work at the computer;
damage to the cardiovascular system. People who smoke may develop arrhythmias, vascular pathologies, atherosclerosis, and hypertension. Such conditions gradually lead to chronic heart failure and the development of poor circulation;
diseases of the digestive system, for example chronic gastritis, peptic ulcer. These pathologies are manifested by pain in the stomach, heartburn, and sour belching. They may be complicated by gastrointestinal bleeding. Also, long-term smoking increases the risk of developing stomach or esophageal cancer;

lesions of the central and peripheral nervous system. A person’s memory may decline, hand tremors may appear, neuroses and depression may develop;
atrophic processes in the body that lead to “drying out” of muscle tissue. The patient develops unhealthy weight loss;
vitamin C deficiency. Nicotine neutralizes and removes ascorbic acid from the body. As a result, the skin becomes flabby, hair begins to fall out, nails break, and teeth crumble. All metabolic processes in the body are disrupted.

First aid for acute nicotine poisoning

What to do if acute nicotine intoxication develops? First of all, you should call an ambulance. This condition is quite dangerous and should be treated by qualified doctors.

Before the ambulance team arrives, you can independently begin providing first aid to the victim. Its main components are listed below.

Take the poisoned person out of the room where the air is contaminated with cigarette smoke.
Place the patient in bed, cover him with a blanket and open all windows and curtains to maximize fresh air into the room.

If a person complains of nausea and stomach pain, perform gastric lavage. In order to cleanse the gastric cavity at home, you need to drink a liter of plain water in one gulp and induce vomiting by pressing two fingers on the root of the tongue.
Give the patient sorbents to drink. If you suspect nicotine poisoning, you can use any drugs from this group, for example, activated carbon, sorbex, polysorb, atoxil, smecta. Before taking them, check the expiration date of the medicine and read the instructions carefully. Sorbents will help reduce intoxication syndrome.
Give the poisoned person water or sweet tea. The liquid will reduce intoxication and improve the condition.
If consciousness is impaired, give a cotton swab soaked in ammonia a sniff. If it does not help bring the person to his senses, place him on a flat surface, lift his legs to the top and turn his head to the side. Before doctors arrive, monitor your breathing and pulse. When they stop, proceed to closed heart massage.

Medical treatment

First aid is provided by an ambulance team. They quickly assess the condition of the poisoned person, provide him with oxygen through a mask, and begin intravenously administering drugs and solutions to reduce the intoxication syndrome and regulate the functioning of the heart and breathing.

After the victim’s condition returns to normal, he is urgently hospitalized at the nearest toxicology department. People in critical and serious condition are treated in the intensive care unit. In parallel with therapy, a detailed examination of the patient is carried out, which is aimed at objectively assessing the person’s condition and identifying complications.

Nicotine poisoning is a serious and dangerous condition that requires qualified medical care. When the first symptoms of intoxication develop, you should call an ambulance. Before the arrival of doctors, it is necessary to provide the patient with fresh air, rinse the stomach, and give sorbents and water to drink. Self-medicating for nicotine poisoning is very dangerous and risky.

They say a drop of nicotine kills a horse and tears a hamster to shreds 😉 This folk wisdom is not far from the truth. A drop of nicotine is a horse dose of poison in the truest sense of the word. Nicotine is extremely toxic to insects and warm-blooded animals.

It acts as a neurotoxin, causing paralysis of the nervous system (respiratory arrest, cessation of cardiac activity, death). The average lethal dose is 0.5-1 mg/kg, which for an adult means about a pack of strong cigarettes smoked at a time. For comparison: for potassium cyanide this figure is only three times higher (1.7 mg/kg). A drop of nicotine is about 1000 mg, which in terms of a lethal dose will be enough to kill a carcass weighing a ton.

Repeated use of nicotine causes physical and mental dependence, which, however, is treatable. Interestingly, patients diagnosed with schizophrenia have an increased smoking habit. Once nicotine enters the body, it quickly spreads through the blood and can cross the blood-brain barrier.

On average, 7 seconds after inhaling tobacco smoke are enough for nicotine to reach the brain. The half-life of nicotine from the body is about two hours. The nicotine inhaled through tobacco smoke when smoking is a small fraction of the nicotine contained in tobacco leaves (most of the substance is burned). The amount of nicotine absorbed by the body when smoking depends on many factors, including the type of tobacco, whether all the smoke is inhaled, and whether a filter is used.

With chewing tobacco and snuff, which are placed in the mouth and chewed or inhaled through the nose, the amount of nicotine entering the body is much greater than with smoking tobacco.

At the beginning of the 20th century, nicotine was the main insecticide used to protect plants. For these purposes, nicotine in the form of a pure substance, its sulfate, and tobacco dust were used, and the pure substance, which was also toxic to mammals, had the greatest activity.

Lethal dose of nicotine in mg

But these data are approximate, since it is necessary to take into account many associated factors - a person’s age, smoking history, individual sensitivity to nicotine, health status, consumption of alcohol, food, and medications.

The body of a teenager is more sensitive to the effects of nicotine, and the lethal dose for a young person will be 10–20 mg. The body of a person who smokes for a long time has adapted to the regular intake of small doses of nicotine, and such a smoker will survive the ingestion of more than 100 mg of nicotine.

In 2013, Austrian scientist Bernd Mayer published his calculations, in which the lethal dose of nicotine is 500 – 1000 mg. The difference of opinion arises because it is almost impossible to introduce a lethal dose of nicotine into the human body, and all lethal doses are calculated in the laboratory.

However, toxicology textbooks indicate a lethal dose in the range of 10–80 mg, and all calculations for restricting the sale of nicotine and nicotine-containing products are based on these data.

How much does a person need to smoke before he dies?

How many cigarettes do you need to smoke to die? The nicotine content in 1 cigarette varies and depends on the brand. On the side of the cigarette pack there is information, including the amount of mg of nicotine. This indicator can be from 0.3 mg to 1.3 mg of nicotine in 1 cigarette.

On average, 1 cigarette contains 1 mg of nicotine. Considering a lethal dose of nicotine of 0.5 - 1.0 mg, let's calculate how much it takes to smoke to die. For a person with a body weight of 70 kg, the minimum number of cigarettes dangerous to life is 35, the maximum is 70.

A person weighing 55 kg will need from 27 to 55 cigarettes to die, and a person weighing 100 kg will need from 50 to 100, respectively. At the same time, a person must smoke them in a very short period of time.

Contrary to all calculations, if a person weighing 70 kg smokes 70 cigarettes, he will not die. This is due to the lower nicotine content in tobacco smoke - only 30%.

Despite this, cases of death have been described when smoking just 2-3 cigarettes. Nicotine had a toxic effect on the nerve centers, cardiac and respiratory arrest occurred, which led to death.

How many die, mortality or statistics of deaths from smoking

More than a billion people around the world regularly use tobacco. This is about 20% of the world's population. Only active smokers are taken into account.

Although tobacco smoke contributes to the development of the same diseases in both active and passive smokers. Every year, 3 to 5 million people die from diseases caused by regular smoking.

Of these, 600 thousand people are passive smokers. The life expectancy of a smoker in a developed country is reduced by at least 10 to 13 years.

The mortality rate among smokers, compared to their non-smoking compatriots, is 30–80% higher. Mortality from smoking increases with the number of cigarettes smoked and the length of smoking. Every second person dies from a disease caused by smoking. 90% of people who die from lung cancer get it as a result of regular tobacco use.

At the same time, the number of smoking people around the world continues to increase every year. If this continues, by 2030 more than 10 million people will die every year from diseases caused by smoking.

In Russia, approximately 1,000 people die from tobacco every day.

Effects of nicotine and cigarettes on the body

Symptoms of acute nicotine poisoning

tobacco odor from the mouth;
headache, dizziness, tinnitus;
weakness, pallor, cold and sticky sweat;
cyanosis of the nasolabial triangle, difficulty breathing;
increased salivation, nausea, vomiting, diarrhea;
increased blood pressure, tachycardia - pulse up to 180 beats per minute or more;
unsteadiness of gait, trembling of limbs, blurred speech.

These symptoms are observed in the first stage of poisoning. And when assistance is provided, they soon pass.

Loss of consciousness occurs, even to the point of coma, breathing becomes shallow and irregular, blood pressure decreases, the pulse becomes rare - up to 20 beats per minute.

Convulsions, epileptic seizures, and respiratory and cardiac arrest may occur. Which, if medical care is not provided in a timely manner, leads to death.

First aid for overdose

If signs of poisoning appear, the patient must be given first aid:

Call emergency medical services.
Place the victim on his side to prevent saliva and vomit from entering the respiratory tract.
Ensure a flow of fresh air - open the windows, free the chest from constricting clothing, remove the tie and belt.
If there is no vomiting, give a warm drink every 15-30 minutes (sweet tea, still water). Alkaline drinks (soda solution) should not be given, as this will enhance the absorption of nicotine in the stomach.
If the patient is conscious, give 4-5 tablets of crushed activated carbon to drink.
In case of poisoning with chewing tobacco, it is necessary to rinse the stomach with a 0.1% solution of potassium permanganate (potassium permanganate) or a suspension of activated carbon (1 tablet per 10 kg of body weight)
If the patient is unconscious, you should keep him in a position on his side with pillows and clothes and wait for the ambulance. Do not give drinks, pills, or induce vomiting, he may choke!
If signs of clinical death appear - respiratory arrest, circulatory arrest, and if you have the necessary knowledge, cardiopulmonary resuscitation should begin.

Snuff and chewing tobacco as an alternative to smoking

In addition to cigarettes, snuff and chewing tobacco (snus) are sources of nicotine. Chewing and snuff are more addictive physically and psychologically than cigarettes. But at the same time they contain fewer toxic and carcinogenic substances.

When using chewing and snuff tobacco, much more nicotine enters the body than when smoking cigarettes. One serving of chewing tobacco contains 5 times more nicotine than a cigarette. When using chewing tobacco, nicotine is absorbed into the blood directly from the mouth and enters the stomach with saliva.

In the case of snuff, nicotine enters the bloodstream, being absorbed through the nasal mucosa. At the same time, the concentration of nicotine in the blood increases more slowly and lasts longer, which means that fewer servings of tobacco will be required than the same number of cigarettes.

It should be remembered that depending on the way nicotine enters the bloodstream, it will have a detrimental effect on the human body.

Effects of nicotine on the body

Before determining a lethal dose of this substance, you need to know how it affects the body.

The respiratory system takes the biggest hit. The negative impact is manifested in the occurrence of a severe cough, which is called a smoker's cough, shortness of breath and the production of copious sputum. Typically, smokers experience these symptoms in the morning and evening. In addition, changes occur in the voice, it becomes low and rough. Due to the occurrence of such symptoms, complications may develop that can lead to chronic bronchitis and, in the worst case, to lung or larynx cancer.

Nicotine also poses a great danger to the cardiovascular system. It quickly penetrates the blood and spreads throughout the body in a matter of seconds. Frequent pressure surges that occur after smoking lead to hypertension and arrhythmia. In addition, this substance constricts blood vessels, which causes oxygen deficiency. Against this background, cardiac ischemia, angina pectoris and, in some cases, heart attack may occur.

The nervous system also stops functioning properly. In the absence of a dose of nicotine, severe irritability appears, which can develop into aggression. In addition, memory deteriorates and headaches may often occur.

The nicotine effects don't stop there. The appearance of smokers also changes. The teeth begin to turn yellow, and an unpleasant odor appears from the oral cavity. The condition of the skin deteriorates and many wrinkles appear. Nails also change color.

Why does a smoker not die immediately after smoking a cigarette?

How then is it possible that a person, receiving daily doses of nicotine, continues to live? There are several answers to this:

after some time, nicotine disappears from the body, so it begins to require another dose;
cigarette smoke contains less nicotine than tobacco leaves, because part of it burns during the smoking process;
formaldehyde contained in tobacco smoke destroys some of the nicotine;
The kidneys and sweat glands help remove nicotine from the body, but the more a person smokes, the more difficult it is for them to cope with their task.

It is worth noting that our body produces nicotine itself, but its dose is tiny. It is involved in the metabolic process in the body. In addition, this substance is found in some vegetables, such as tomatoes, bell peppers and potatoes.

Drawing conclusions, we can say that a lethal dose of nicotine does not enter the bloodstream during daily smoking. This can only happen if a person smokes several cigarettes at the same time.

What dose is considered lethal?

Scientists have found that the lethal dose of this substance is 1 mg per 1 kg of body weight. But it’s very difficult to say for sure, because these numbers can be influenced by many factors, such as age, smoking experience, general health, environmental situation of the place of residence, and much more. In addition, this indicator is affected by the consumption of alcoholic beverages and taking any medications.

For teenagers, 50 mg of nicotine is considered a lethal dose. A growing, not fully formed organism is most sensitive to the effects of nicotine.

If a young person decides to smoke 10 cigarettes in a row, the result can be fatal.

One pack of cigarettes contains a dose that can take a person’s life. But rarely is anyone able to smoke a large number of cigarettes at one time, because his health deteriorates sharply, vomiting appears and a strong feeling of disgust arises, so the act of smoking stops and the lethal dose does not enter the body. However, you should be especially careful, since There have been cases when just 2-3 cigarettes smoked in a row took lives. This was due to the stoppage of the heart and respiratory organs.

Thus, instant death occurs quite rarely, but it is worth considering the enormous harm that nicotine causes to the body. The prolonged influence of this substance on all organs will stop their functioning. There can be only one result of such a phenomenon, and it is far from comforting. Therefore, be careful with the addiction to smoking and if you want to maintain your health, then it is better to get rid of it.

But despite this, dying from nicotine poisoning is very rare. If one cigarette contains 1 mg, then the maximum lethal dose for a 70-kilogram man is contained in 70 cigarettes. But after smoking them, he does not die. Why?

First: Tobacco smoke contains less nicotine than tobacco leaves because most of the alkaloid is burned off when smoked. It has been proven that cigarette smoke contains only 30% of the total amount of nicotine in tobacco.
Secondly: cigarette smoke that enters the oral cavity comes into contact with the mucous membranes of the mouth and bronchi for a very short time, and then is exhaled. During this time, all the nicotine in the smoke does not have time to be absorbed into the blood.
Thirdly: tobacco smoke contains a substance - formaldehyde, which destroys part of the nicotine.
Fourth: nicotine enters the smoker’s body in small doses, and this makes it possible to adapt to it.

Therefore, it is almost impossible to get such a large dose of poison into the blood at once when smoking.

Deaths from nicotine poisoning do not occur from its direct effects, but from a toxic attack on the nerve centers in the brain. This leads to a reflex stop of breathing and heart function.

Theoretically, one can imagine that a person will smoke several cigarettes at once or one after another. But in this case, acute nicotine poisoning or disgust will most likely occur, which will manifest itself as nausea and vomiting, which will stop further smoking.
The body's sensitivity to nicotine also matters. For example, the body of a teenager is approximately two times more sensitive to poison than the body of an adult. Therefore, the lethal dose of the alkaloid here will be two times less than in an adult.

But there is another source of nicotine - tobacco. It can be snorted and chewed. When used this way, much more nicotine enters the bloodstream than when smoking, which can also cause intoxication.

There is also a danger of poisoning if a person accidentally or intentionally swallows tobacco or a cigarette. In this case, the most terrible poisoning awaits him. For a child, even half of a cigarette eaten can be lethal!

But in any case, it is almost impossible to introduce a lethal dose of this poison into the body! All experiments to establish the lethal dose were calculated in laboratory conditions.

Based on the above, we can conclude: nicotine, as a substance involved in the activity of the nervous system, can cause serious changes in the functioning of organs. The higher the concentration of this alkaloid, the stronger the body's response. Under the influence of this toxin, blood pressure increases, the activity of the heart and respiratory center is inhibited, which can cause death.
