Permissible level of alcohol while driving. Permissible alcohol limit

In Russia in 2015, the number of accidents committed by drivers while intoxicated increased sharply. Legislators, trying to reduce the number of "alcoholic accidents", on the one hand, are tightening the responsibility for drunk drivers, on the other hand, they are improving legislation in the field of determining the level of alcohol in the blood.

Let us tell you in more detail what threatens drunk drivers, what is the permissible rate of alcohol while driving in ppm in 2019 in Russia. Is 0.16 mg/l alcohol in exhaled air and 0.35 ppm the same thing?

The task of legislators is to exclude situations when drivers who have drunk kvass, non-alcoholic beer or other drinks with a minimum alcohol content fall under the deprivation of their rights. The experience of the period from 2010 to 2013, when the driver had to exhale absolute zero per mille, showed the actual impossibility of complying with such a norm.

How many ppm is allowed in 2019 in Russia?

Let us turn to the law: the established indicators are contained in Art. 12.8 of the Code of Administrative Offenses, or rather, in a note to it. In particular, it states that liability under this article occurs if the driver is found to have alcohol at a concentration of 0.3 grams per liter of blood or 0.16 milligrams per liter of exhaled air.

What is ppm?

Promille is a unit of measure that characterizes the concentration of alcohols in physiological media. The indicator is 1/1000 of a number and is indicated by the symbol ‰ (that is, 1/10 percent). 1 ppm = 1 gram of pure alcohol per liter of blood.

The permissible rate of alcohol driving in ppm in 2019 in Russia is:

• 0.356 ppm - on exhalation (0.16 mg / l),
• 0.3 ppm - in the blood.

This provision was introduced by Law No. 62-FZ “On Amendments to Article 12.8 of the Code of Administrative Offenses of the Russian Federation”, signed on April 3 and entered into force on July 3, 2018. The note now fixes the allowable rate of ethanol not only in the exhaled air, but also in the blood.

The innovation was introduced taking into account the total errors. In other words, this is not permission to drink some alcohol and drive, but protection for those citizens who may lose their rights by mistake.

The error is often due to a malfunction of the measuring instruments: the determination of the concentration "by blood" is much more accurate than "by air".

In addition, ethanol can appear in the body not only in those who abuse alcohol:

• alcohol can be produced endogenously in humans in the presence of certain disorders and diseases (for example, with yeast infections of the gastrointestinal tract);
• ethanol is also included in some medicines, drinks and food products (chocolate candies, kefir, koumiss, non-alcoholic beer, kvass, natural fruit juices, sauerkraut, rye bread, etc.).

Liability for drunk driving

The permissible per mille of alcohol is an important indicator, since it affects the qualification of the offense committed. Recall that drivers who have sat behind the wheel while intoxicated can be held administratively or even criminally liable. In the first case, according to Art. 12.8, Art. 12.26 of the Code of Administrative Offenses, in the second - according to 264 and 264.1 of the Criminal Code.

The law is harsh on drunk drivers, you can almost always lose your license, the terms and measures differ:

• when driving while intoxicated, the violator “shines” a fine of 30 thousand rubles;
• the same amount will be fined if the control was transferred to a drunk person, the driver refused to be examined;
• if such a driver does not have a license, an administrative arrest lasting 10-15 days is added to the fine.
• for a repeated violation or for a repeated refusal of a medical examination, liability arises under the Criminal Code: a fine of 200-300,000 rubles, up to 480 hours of corrective work, up to 2 years of forced labor, deprivation of rights for 3 years.
• if an accident at the same time caused someone's death, you can go to jail for 2-9 years.

How did the allowable ppm change in Russia?

Responsibility for drunk driving was first introduced in the USSR, in 1956. In 1974, the Union ratified the Vienna Convention on Road Traffic, according to which the alcohol content should not exceed 0.8 ppm. In 1988, by decree of the Ministry of Health, the norm was set at 0.2 ppm. In 2003, the allowable rate was raised to 0.5, and later reduced to 0.3, along with the adoption of a new Code of Administrative Offenses in 2008.

Accordingly, until 2010, the values ​​close to those accepted now were in force in the Russian Federation. Recall that previously 0.15 mg / l was allowed, and now it is 0.16 mg / l.

In the most stringent years, 2010-2013, this proportion was 0, with the detection of 0.01 mg of ethanol, one could lose the rights.

What about in other countries?

Let us turn to the experience of other states. The permissible rate per mille behind the wheel in 2019 for drivers of Belarus is 0.3. The value was fixed by a resolution of the Council of Ministers of August 2, 2011, and before that it was higher - 0.5 ppm. If driving at this concentration results in an accident, the ethanol content will act as an aggravating circumstance.

There are states where prohibition generally applies, which also applies to drivers. This is the situation in the United Arab Emirates, Brunei. Surprisingly, some countries of tolerant Europe adhere to the same rules: the Czech Republic, Slovakia, Romania, Hungary.

How much per mille is allowed while driving in 2019 in Europe, the USA and a number of others: table

Things are quite strict in the Baltic States and some of its neighbors: up to 0.2 ‰ is allowed in Estonia, Lithuania, Latvia, Poland, Norway, and Sweden. In Asia, China follows the same rule. The Germans approached the issue in an interesting way: young and inexperienced drivers are allowed 0 ‰, the rest - up to 0.5. In some European countries, the permitted rate sometimes reaches 0.8 ppm.

In the context of current economic realities, the amount of monthly alcohol consumed in the Russian Federation is increasing in an algebraic progression. Russians, who, due to objective economic reasons, are not able to make ends meet, are increasingly kissing the bottle, trying to find answers to their most pressing questions at the bottom of the glass. It is no secret that motorists do the same, who, after heavy drinking, are often drawn to the wheel. About what rate of alcohol is permissible in the current year, and will be discussed in this article.

Permissible alcohol limit in ppm in 2016.

The main legislative innovation of the current year is that, in contrast to 2010-2013. today in the Russian Federation it is allowed to have a certain amount of alcohol in the driver's blood. The need to abolish zero ppm was dictated, first of all, by the fact that due to the consumption of certain foodstuffs that obviously do not contain alcohol degrees, used by the traffic police, special equipment detects the presence of a small amount of alcohol in the driver's blood. Among other things, we are talking about:

• non-alcoholic beer;
• warm juices;
• overripe bananas;
• chocolates;
• oranges;
• mouth fresheners;
• kvass;
• medicines;
• kefir;
• curdled milk, etc.

Each of the listed products contains a small amount of alcohol. For example, before the abolition of the rule on zero ppm, a glass of cold kvass drunk by a driver on a hot, sultry day could threaten him not only with a fine, but also with the deprivation of a driver's license for driving while intoxicated.

According to the latest amendments to the current Code of Administrative Offenses and SDA, at the moment the permissible rate of alcohol in the blood of a driver is 0.35 ppm, and in the air exhaled by him - 0.16. It is important to understand that drinking two glasses of kvass increases the level of alcohol in the body to 0.19 ppm, however, for a very short time. Therefore, in order to avoid excesses, drivers are not recommended to abuse this bread drink, and if the temptation still could not be avoided, then you should not drive immediately after quenching your thirst.

How is the level of alcohol in the body measured?

To measure the level of alcohol in the driver's body, it is traditionally customary to use a special value - ppm. So, 0.1 ppm indicates that one liter of blood of a motorist contains 0.045 mg of alcohol. It is important to understand that alcoholic vapors disappear from the human body for quite a long time, which should always be remembered when participating in a feast on the eve of a car trip. The intensity of such weathering is directly dependent on the type of alcoholic beverage drunk by the motorist, as well as the age and weight of the latter. For example, if 100 grams of vodka disappears from a 100-kilogram driver in about three and a half hours, then his 60-kilogram counterpart will have to wait at least 5 hours and 48 minutes before the alcohol is completely eroded from the body.

What are the risks of drinking alcohol while driving?

A driver caught drinking alcohol for the first time while driving will face a fine of 30,000 Russian rubles and deprivation of a driver's license for up to 2 years. A repeated offense, according to the current Code of Administrative Offenses, is punishable by a fine of 50 thousand rubles and deprivation of rights for three years. At the same time, being caught by the traffic police while driving while intoxicated, an already fined driver can be imprisoned for up to 15 days.

Refusal to conduct a medical examination is fraught with a fine of 30 thousand Russian rubles, as well as the deprivation of a driver's license for up to 2 years.

This article will focus on the permissible level of alcohol in the blood of a driver, what they are measured in, how to understand that the maximum permissible level has long been exceeded, and much more about alcohol consumption by a motorist.

Let's not dissemble, but situations sometimes develop unpredictably, and even yesterday's supporter of sobriety behind the wheel, having taken a "hot drink", gets behind the wheel and becomes a road user. This is associated with a high risk of becoming a participant, and even the culprit of a traffic accident. However, many consciously accept this risk, getting behind the wheel after drinking a glass of beer, wine or an alcoholic cocktail.

How is blood alcohol measured?

If we are talking about driving a motor vehicle while intoxicated, then the term " ppm».

This word is firmly connected with the degree of alcohol intoxication, in ppm the concentration of alcohol is measured, or rather, the quantitative ratio of the volume of alcohol to the volume of blood.

Literally translated from Latin, per mille is one thousandth of the volume of something or a tenth of 1%. But, as mentioned above, when they hear the term “per mille”, the vast majority of people know that it will be about drunk driving or a medical examination for blood alcohol content. Experts also interpret this term as the equivalent of the volume of pure alcohol in the blood: 1 ppm = 1 ml of pure alcohol in the blood.

What is the norm of alcohol in the blood in Ukraine 2018?

In Ukraine, alcohol intoxication for drivers behind the wheel is considered to be more than 0.2 ppm of alcohol in the blood. This norm is enshrined in the Order of the Ministry of Internal Affairs of Ukraine and the Ministry of Health of Ukraine No. 400/666 dated 09.09.2009. Thus, the establishment of the state of alcohol intoxication of the driver is carried out by a traffic police officer using special measuring instruments, which are also called breathalyzers.

The norm of alcohol in the blood of 0.2 ppm in Ukraine is considered the background and does not entail any sanctions. However, this figure is negligible, and you can exceed it even without drinking alcohol.

There are cases when an indicator of 0.2 ppm and above was noted in:

• people with diabetes;
• For some stomach disorders;
• With diseases of caries;
• With a disorder of the gastrointestinal tract, accompanied by diarrhea;
• When using certain medications.

In practice, there have been cases when the permissible alcohol in the blood was exceeded after drinking kvass and even kefir. This should be borne in mind by those who are confident in their impunity, balancing on the fragile border, which lies at around 0.2 ppm. It is wiser to completely abandon the use of alcoholic beverages if you have to drive a car, even if it is a trip for a short distance, and you only drink a glass of dry wine.

How much alcohol leaves the blood?

In practice, many experts are trying to find the most accurate algorithm that can be contained in the wording: “How much and what can you drink so as not to break the law and avoid punishment?”. An exact answer has not yet been found, because the concentration of alcohol in the blood depends on a person's body weight, age, metabolic rate and other specific factors.

For example, if an average man weighing 70-75 kg drinks a 500 ml bottle of vodka, then he will have 2.5 ppm of alcohol in his blood. This may qualify as severe alcohol intoxication.

An indicator of 5 ppm of alcohol in the blood is considered life-threatening and can lead to death. 5 ppm = 2 bottles of 0.5 vodka each.

Let's try to understand how long alcohol remains in the driver's blood.

The time of alcohol in the blood, the period of its withdrawal, as well as its concentration in the blood, depend on a combination of factors. The main ones are:

1. person's weight;
2. Age;
3. Health status;
4. metabolic rate;
5. The amount of food before drinking alcohol;
6. The amount of food after drinking alcohol;
7. Qualitative indicators of products used in the form of snacks.

For clarity, we suggest that you familiarize yourself with the table, which shows the averaged data obtained empirically. When using the results in the table, do not forget that it is important to take into account the weight and gender of the person.

For example, after 3 hours, drinking 100 grams of vodka will not be considered a violation of the rules, since alcohol vapors will no longer be recorded by a breathalyzer.

Considering that the data given in the table are averages, nevertheless, the information contained in it can give an approximate answer to the question "How much alcohol comes out of the blood."

It should be understood that an accurate result on the content of alcohol in the blood can give a medical examination with a laboratory blood test for alcohol.

Tables of alcohol in the blood, or how long does a particular drink take?

Our article would not be useful enough if it did not contain information about how much alcohol is contained in a particular drink. The table below shows the time indicators for men and for women, during which alcohol is kept in the blood.

In the following two tables, you can see the readings of the breathalyzer, which will show how much per mille of alcohol in the blood, depending on the amount drunk, as well as the sex and weight of the driver:

One dose in this case corresponds to the following servings of different drinks:

• 50g of any 40-degree drink - vodka, cognac or whiskey
• 100g 20 degree port wine
• 150g 12-degree dry wine
• 1 bottle (0.5l) 4-degree beer
• half a can (0.25l) of a 9-degree tonic.

In this case, the number of ppm will be maximum a few minutes after drinking alcohol, since the vapors contained in the oral cavity will have a maximum concentration. Half an hour after consumption, this figure will decrease significantly.

For example, after drinking 0.25 liters of beer (a conditional half a bottle of light beer), the breathalyzer will show 0.16 ppm “at the exit”.

Therefore, a 0.5 liter bottle of beer will increase the alcohol concentration to 0.3 ppm. Of course, dark varieties will be stronger and at the same volume as light varieties will result in a higher alcohol content. You should also take into account the characteristics of different manufacturers and brands within each variety.

The use of a conventional bottle of wine with a volume of 0.7 liters and a drink strength of 12% will lead to a result of 0.7 ppm.

After drinking 100 grams of vodka, the blood alcohol level will be 0.55 ppm. And again, it is worth emphasizing the conditionality of these data, since the results of 0.7 ppm after drinking 200 grams of vodka were experimentally recorded.

Blood alcohol calculator

To assist in calculating the level of alcohol in the blood, some specialized resources offer their users the service of an alcohol calculator online. This simple service was created by analogy with the algorithm that was described in the section “How long does alcohol stay in the blood” (see above).

However, the creators of such online calculators use a more accurate calculation method, which is called the Widmark formula. The formula, compiled by a Swedish chemist, contains data on the amount of alcohol consumed, human body weight, a distribution coefficient of 0.6 for women and 0.7 for men.

To use the online service and make a calculation of alcohol in the blood, you need to enter data on your weight in kilograms, the amount of alcohol you drink, the type of alcohol (if you have consumed several types of alcohol, then you need to indicate the corresponding value for each). Then put a mark on the degree of fullness of the stomach while drinking alcohol and the result will be obtained in a second.

Degrees of intoxication and the number of ppm

• Mild degree - with a result of 0.5-1.5 ppm;
• Average - 1.5-2.5 ppm;
• Strong degree - 2.5-3 ppm;
• Severe alcohol poisoning with the threat of death - 3-5 ppm.

How can you speed up the elimination of alcohol from the body

In order for the breathalyzer test to show nothing, some steps should be taken to speed up the removal of alcohol from the body.
The most effective way is drug detoxification using a complex of drugs.

If alcohol intoxication is mild to moderate, then you should:

1. Stop further alcohol intake;
2. Plentiful drink (water without gas);
3. Sweet and strong tea or coffee;
4. If necessary, gastric lavage should be carried out;
5. Moderate physical activity will help speed up the metabolism;
6. A contrast shower also improves sweating and eliminates toxins;
7. Ammonia diluted in a glass of water can sober up a person (10 ml per half glass of water).

The intake of alcoholic beverages should be strictly dosed, especially for those who plan to drive a vehicle in the coming hours. For those who have already got behind the wheel, drinking alcohol should become the strictest taboo, which is not allowed to be violated under any circumstances. It is better to save yourself and other road users from the possible dire consequences that can result from distracted attention, reduced motor skills and impaired reaction time after drinking alcohol.

Even if the accepted dose of alcohol does not exceed the notorious 0.2 ppm, the driver's coordination, orientation in space, attentiveness and ability to instantly respond to external circumstances on the road are disturbed.

plus

The harm of alcohol has long been proven, but people are not ready to completely abandon its consumption at the moment. Alcoholic drinks can be different, and they differ, first of all, in the number of "degrees" - the alcohol content. Depending on the degree of alcohol, its effect on the human brain varies. In a state of alcoholic intoxication, the reaction time to ongoing events increases. In order to reduce the number of traffic accidents, driving under the influence of alcohol is prohibited.

Allowable ppm driving in 2019

In 2010, the government of the Russian Federation approved that drivers, when passing an examination for alcohol content, both in exhaled air and in blood, should have a zero value. This law was in force until 2013, when it was decided to revise it. This is due to the fact that the consumption of certain non-alcoholic foods and drinks can cause reactions, as a result of which, when checking the driver’s condition, the presence of ppm will be recorded on breathalyzers. For example, “intoxicating” products include:

• Chocolate;
• Kvass;
• Kefir and other fermented milk products;
• Oranges, apples, bananas;
• Mouth fresheners, chewing gum;
• A number of drugs.

The above is a far from complete list of products, after consumption of which the presence of alcohol in the form of ppm can be recorded in the exhaled air and blood.

Note: This list includes non-alcoholic beer. After it, the breathalyzer will show the presence of alcohol in the driver's blood, but no more than after kvass. Thus, drinking non-alcoholic beer before a trip is not prohibited in 2019.

In 2013, the "zero ppm" law was revised and amended. This is due to the fact that sober drivers were fined and deprived of their license for the minimum presence of alcohol in the blood, while they could not drink alcoholic beverages for several weeks, months or even years before the trip, and the appearance of ppm was caused by other products.

In 2019, the following permissible per mille behind the wheel are established in Russia:

• In the blood: no more than 0.35 ppm;
• In exhaled air: no more than 0.16 ppm.

If, during the test, the breathalyzer shows values ​​​​less than acceptable, the driver has the right to drive a car.

What threatens drivers for exceeding permissible norms per mille in 2019

A drunk driver driving a car is a potential threat to other people. The State Duma is actively discussing the idea of ​​toughening the responsibility for driving while intoxicated. In 2019, the following punishments for drunk drivers are provided:

• If the driver is caught for the first time in a state of intoxication, he is punished with a fine of 30 thousand rubles. He is also deprived of a driver's license for a period of 1.5 to 2 years, for which he will need to pass a theoretical exam at the traffic police;
• If the driver is caught for the second time in a state of intoxication while driving a car, he is punished with a fine of 50 thousand rubles. He is also deprived of his driver's license for 3 years, for the restoration of which he will need to pass an exam in the traffic police.

Important: Refusal of a medical examination for alcohol intoxication is actually a confirmation of the driver that he is in a state of intoxication while driving. In this case, the punishment is identical - a fine of 30 thousand rubles and deprivation of rights for 1.5-2 years.

It is necessary to note some important points that relate to the punishment of drivers in a state of intoxication while driving:

Note: If the driver got drunk in an accident, the insurance company has the right to refuse to pay insurance to him.

When can you drive after drinking alcohol?

There are various “legends” among drivers that tell how soon after drinking alcohol you can drive a car. Someone says that after drinking a bottle of beer you need to wait 4 hours before driving, others say that 2-3 hours is enough. In fact, the time is calculated for each person individually, depending on his body weight, degrees in alcohol consumed, metabolism, and some personal medical indicators.

The average values ​​when, after drinking alcohol, you can drive, so that the breathalyzer shows the permissible ppm, are shown in the following table:

Each driver must individually calculate the amount of ppm in the blood in order to avoid punishment for driving under the influence of alcohol. For example, if a man weighing 60 kg drank a liter of beer 5.8 degrees in the evening after work at 22:00 and went to bed, he received about 2.14 ppm. For an hour, about 0.1-0.15 ppm leaves the male body, and about 0.085-0.1 ppm from the female body. Accordingly, the driver can get behind the wheel and not be afraid of being deprived of his rights around 16:00 the next day.

Every year the measure of responsibility for this violation of traffic rules is becoming tougher. Everyone recognizes the social danger of such a violation, but not everyone agrees when deciding what dose of alcohol in the blood or exhaled air must be established in order for the driver to be found guilty of drinking while driving. And this is a very serious issue for all road users and especially for drivers. In addition to the above-mentioned fine and deprivation of rights for the abuse of alcohol while driving, you can get an administrative arrest, or be held criminally liable. Read more about this.

There are countries that allow moderate drinking while driving.

Permissible norms

Russian legislation (Article 12.8 of the Code of Administrative Offenses, note) prohibits the driver from using any substances that lead to intoxication. These include alcohol, drugs, psychotropic and toxicological substances. Responsibility for violation of the requirements of this article, as well as article 12.27 part 3, concerning the ban on taking intoxicants after an accident, occurs only when the fact of the presence of ethyl alcohol vapors in the air exhaled by the driver is established. The presence of psychotropic or narcotic substances in the driver's body is determined by the results of a blood and urine test.

Alcoholic drinks that will give 0.3 ppm after a certain time

The units used to measure drunkenness are "milligram per liter" (mg/l) and "per mille" (‰). The law establishes the permissible content of alcohol while driving at 0.16 mg / liter in the exhaled air or 0.35 ppm in the blood.

It is important to understand:

1. During a medical examination, blood from a vein can be taken for analysis and then the alcohol content will be indicated in ppm.
2. The examination is carried out by a breathalyzer. Alcohol vapor is found in exhaled air and will be measured in milligrams per liter (mg/L).
3. In the act of medical examination, which is drawn up when fixing the driver's alcohol intoxication, the alcohol concentration is always indicated in mg / l, and not in ppm. These are, as they say in Odessa, two big differences.

The difference between measurements in ppm from milligrams per liter

Promille - this word denotes a thousandth of a certain value, i.e. one tenth of a percent represented by the symbol "‰". This unit of measure is used to denote the number of thousandths of a physical quantity. To understand the difference between "‰" and "mg / l", you should understand the following points for yourself:

1. mg/l is a unit of measure for the concentration of alcohol in the air;
2. ppm is a unit of measure for the specific content of alcohol in the blood.

It has been established that there is a strictly proportional relationship between the number of alcohol molecules contained in a unit volume of lung air and its content in the patient's blood.
Thus, ppm and mg/l are units of measurement for various physical parameters, but they are related. Medical studies have shown that a person whose blood contains 1 ppm of alcohol exhales air with an alcohol concentration of 0.45 mg / l. Therefore, ppm is related to mg/l by a constant ratio of 1:0.45. Therefore, 1 ppm \u003d 0.45 mg / l.

The legally permitted breath alcohol content of 0.16 mg/l corresponds to the blood alcohol limit of 0.35 ppm.

There are devices whose readings can be taken both in milligrams / liter and in ppm. However, in any case, when issuing a medical examination report, the readings of the device should be indicated in mg / l, as determined by the requirement of Article 12.8 of the Code of Administrative Offenses, which may require recalculations in some cases.

The question arises, where did this figure come from - 0.16 mg / l or 0.3 ppm?

This value is defined in the law as the total measurement error obtained using the measuring instruments available in operation. That is, the allowable rate of 0.16 mg / l should be understood not as an indicator of intoxication, but as an inaccuracy in the readings of the device. Thus, if the device shows 0.16 mg / l or more, then it is considered that the driver drank alcohol. This means that the permissible level of alcohol for a driver is 0.16 mg / l or 0.35 ppm, if more, this is already alcohol intoxication.

The law does not state that the readings of the device must be confirmed by other signs of intoxication, such as unsteady gait, lack of coordination, etc. Therefore, the performance with the use of special devices that issue the measurement result on a paper medium does not require clinical confirmation of the results by conducting an additional examination in order to identify other indirect signs of the state of intoxication and record its results in the corresponding act of execution of this procedure.

The requirements of the law imply complete sobriety of the driver without discounts on various low-alcohol tonic drinks in the form of "energy drinks" or beer, which are allowed in a number of foreign countries. The threshold in the form of a permitted alcohol rate of 0.16 mg / liter was made in order to remove problems with the error in the readings of the device, as well as with the existing natural dose of ethanol in the blood of a certain category of people.

The measurement accuracy limits of instruments used to determine the concentration of alcohol in the air are established by Rosstandart on the basis of studies of various types of breathalyzers approved for practical use. Moreover, the limits are defined with some margin. The measurement accuracy declared by the manufacturers of measuring instruments is from 0.03-0.04 mg / l for most devices.

The rest of the margin of permissible error values ​​is calculated on the influence of adverse climatic and other conditions in the measurement process, such as temperature and air humidity. It also levels the measurement results in relation to instrument types. Whatever type of device is used for medical examination, the lower threshold is the same for all - 0.16 mg / l.

How much do you need to drink to have 0.3 ppm in your blood?

The maximum concentration of alcohol in the body is reached 0.5-2 hours after drinking. Drinking a glass of vodka, a person consumes 40 grams of alcohol, which will be absorbed into the blood in the form of 0.5-0.6‰. Oxidation of alcohol in the body occurs at a rate of 7-10 g/hour. This corresponds to a decrease in its content by 0.1-0.16‰. This means that in order for the drunk alcohol to “weather” from the body to the permissible limit, at least 4-5 hours must pass after drinking.
