Whether a person is drunk or not depends on the concentration of ethanol in the blood. When the concentration of ethanol in blood is 0.05-0. 1%, people begin to be slightly drunk and carefree; When it reaches 0.3%, people will be inarticulate and hesitant, which is what we often call drunkenness.
The tolerance of ethanol varies from person to person. After drinking, about 20% of the alcohol is absorbed by the stomach and 80% by the duodenum and small intestine. The toxic dose and lethal dose of alcohol vary from person to person. The general toxic dose is 70-80g, and the lethal dose is 250-500g.
Whether poisoning occurs is related to the following factors: whether there is food in the stomach (fast absorption on an empty stomach), whether you have eaten fatty food (fatty food can slow down the absorption of alcohol), whether the gastrointestinal function is good (good absorption of gastrointestinal function is fast), and the ability of human body conversion agent to deal with alcohol (it can quickly convert ethanol into acetic acid and is not easy to be poisoned).

The danger of drunkenness
The main component of wine is alcohol, and its chemical name is ethanol. When ethanol enters the human body, it will have many destructive effects.
1, when the alcohol concentration in blood reaches 0.05%, the effect of alcohol begins to appear, and excitement and euphoria appear; When the alcohol concentration in blood reaches 0. 1%, people will lose their self-control ability. If it reaches 0.2%, people have reached the point of being as drunk as a fiddler; When it reaches 0.4%, people will be unconscious, unconscious and even life-threatening.
2. The most important thing is the central nervous system. It makes the nervous system from excitement to high inhibition, which seriously destroys the normal function of the nervous system. Excessive drinking can also damage the liver. Chronic alcoholism can lead to alcoholic cirrhosis.
PS。 Chronic alcoholism is harmful to health in many ways. It can lead to multiple neuritis, myocardial injury, brain injury, hematopoietic dysfunction, pancreatitis, gastritis and ulcers. And it will also increase the incidence of hypertension. Others have noticed that long-term heavy drinking will harm germ cells and lead to mental retardation in future generations. The incidence of laryngeal cancer and digestive tract cancer in people who drink a lot has increased significantly.
