Alcohol can cause serious harm to health, even life-threatening.
When a person drinks alcohol at such a speed that the body does not have time to process it, alcohol poisoning occurs.
Seek immediate medical attention if any of the following symptoms occur: confusion, severe vomiting, seizures, slow or irregular breathing, pale or bluish skin, low body temperature, or loss of consciousness.

Before the ambulance arrives, ensure the safety of the victim: place him in the recovery position, cover him with a blanket and try to keep him conscious.
You can offer the person a drink of water, and if the person is vomiting, help him not to choke on the vomit.
However, it is not recommended to try to induce vomiting on your own: this way the alcohol will not leave the blood, but the poisoned person will feel worse.
What else should you not do in case of alcohol poisoning?
Trying to "sleep it off"
In a dream, a person may lose consciousness, and if he starts vomiting, he risks choking.
Drink coffee
Drinking coffee and other drinks that contain caffeine can cause dehydration and can also increase blood pressure.
Take a cold shower
The cold causes vascular spasm, increased blood pressure and pulse. Often, after such "procedures", the victims were diagnosed with a heart attack.
There is fat
This technique can be used as a preventative measure against alcohol poisoning, but once the poisoning has already occurred, it will not help – as a result, the stomach will become even more upset.
