What determines the rate of removal of alcohol

To find out how much alcohol is contained in the blood, it is necessary to study the personal characteristics of the human body. In some, alcohol in the blood is weathered quickly, others will take more time. There are a number of parameters that affect the time of exit of alcohol from the body:

  1. Gender - the elimination of alcohol in women, appears more slowly than in men.
  2. The general condition of the body - stressful situations, exercise increases sensitivity to alcohol.
  3. The amount drunk - the more drunk, the longer the time spent in the body of alcohol.
  4. Age - if a person is young, then alcohol will erode more quickly.
  5. Weight category - with less weight alcohol erodes longer.
  6. The alcohol content in percent.

Estimated time alcohol content

For example, a man weighing 60 kg will drink 0.5 gr. 6% of beer - alcohol disappears within 1, 5 hours.

  • 100 gr. champagne - 1, 5 hours.
  • 100 gr. vodka - disappears 4 hours. If a person drinks a bottle of vodka, he will sober up in 20 hours.
  • 100 gr. Cognac - 6 hours.
  • 200 gr. wine - 3 hours. The greater the strength in alcohol and the weight of a man, the longer the removal of alcohol from the body.

How much does alcohol in the body? Under normal conditions, the alcohol completely disappears after 2 weeks.

How long does alcohol stay in exhaled air

Alcohol disappears for a long time. The rate of weathering depends on the amount drunk. There is an erroneous opinion that a small amount of alcohol can be removed by using a dense snack, taking a contrast shower, drinking strong tea or coffee. This is a fallacy. None of the above does not affect the rate of removal of alcohols from the blood.

Alcohol testing in traffic police

When ingested, the alcohol breaks down into its constituent parts. An oxidation reaction occurs. This condition is called intoxication. The amount of alcohol from venous blood enters the exhaled air. For the driver of the car is essential, how much time alcohol is in the air. Initially, DPS officers visually determine whether the driver has drunk or not.

Alcohol was thoroughly eroded after 4 hours, but for about 2 days there will be a residual concentration of alcohol in saliva, sweat, urine, and also in exhaled air.

To determine how much alcohol is eroding, you need to understand that it all depends on time, speed of use and amount of alcohol consumed. Alcohol is removed from the lungs at the speed of one shot glass (about 30 grams) in 60 minutes. Within an hour, the body will return to normal. When the level of alcohol in the body ranges from 100 to 250 grams., Cleansing can take up to 18 hours.

You should be aware that portable devices have an established error and may be inaccurate in the readings.

In service with the staff of DPS is a device with the possibility of remote analysis - alkalaser. It allows you to detect the presence of alcohol vapors at a distance of up to 15 meters even in a moving car. Alkolazer has the form of a small fire extinguisher. On the front of the analyzer there is an optical window through which the laser beam passes.

The principle of operation of an alkolaser is spectral analysis.

Not far from it is a video camera, fixing the driver. The laser beam checks the approaching car interior, detects ethyl alcohol vapors and transmits a signal to the traffic police officer. Such a device has been seriously tested for suitability.

The dangers of drunk driving

Severe intoxication of the driver leads to a decrease in physiological capabilities, the psychological processes that determine the timeliness of actions in difficult road conditions are disturbed. A drunk man underestimates the danger and complexity of the situation. During intoxications, the angle of view is narrowed, the perception of the road situation is slowed down, attention and thought are disturbed.

Scientifically proven, with a content of 0.3 ppm of alcohol in the driver’s body, his reaction is already decreasing.

Alcohol increases the risk of an accident. This entails serious consequences for the health and life of the driver. According to studies, drunk drivers during an accident, were injured more dangerous than sober. This is explained by the fact that a drunk person is unable to assess the situation on the road in time and take security measures in a timely manner.

If the driver has used 150 grams. vodka or brandy, eyes perceive colors worse and attention decreases.

When using a larger dose, the angle of view is significantly narrowed, the control over the road disappears. This increases the chance of complete loss of control of the car.

Answering the question about a certain time for the elimination of ethyl alcohol, we note that on average - it is from 3-8 hours. After 2 hours, the main part of the alcohol is displayed, the remaining - after about 8 hours. Completely alcohol leaves the body in 1-2 weeks.

Examination to stay in a state of intoxication

Examination is carried out by traffic police officers for the presence of alcohols in the driver’s body, driven by the vehicle

Validation rules:

  1. The basis for the test are signs: the smell of "fume", incoherent speech, instability, a sharp redness of the face, hand shake, inappropriate behavior.
  2. The traffic police officer should tell about the measurement and show the working breathalyzer.
  3. When determining the status of the driver takes into account the permissible error of the device.
  4. The presence of witnesses during the measurement is mandatory.
  5. The result of the study is recorded in the document. The certificate of inspection on a condition of alcoholic intoxication is signed by witnesses, the driver and the inspector.

In case of disagreement with the result, the driver can undergo an independent medical examination and refute the result of the study.

The entire test procedure on the state of alcohol driver is regulated by law.
