There is a clear definition of drunkenness in medicine. The definition of acute poisoning given by ICD- 10, the international standard classification of the World Health Organization, is that the use of psychoactive substances leads to a certain degree of consciousness, cognition, perception, judgment, mood or behavior, or other psychophysiological functions and reaction disorders.
This disease is related to the acute pharmacological action of the substances used and the learned reaction of people. Unless there is tissue damage or other complications, this disorder will be relieved over time and eventually fully recovered.
Extended data Alcohol is the most widely used psychoactive substance in the world, and the poisoning caused by drinking a lot in a short period of time is what we usually call alcoholism.
There are two points in this definition that deserve special attention. One is "a certain degree" of central nervous system dysfunction, which means that as long as the brain function and behavior are affected after drinking, it can be called drunkenness. The dysfunction is temporary and can be completely recovered in the end.
Usually, alcohol is absorbed by gastrointestinal tract soon after drinking, which leads to the increase of BAC. Usually, an adult weighing 70 kg drinks 1 standard cup (containing14g pure alcohol, the amount of catabolism within 90 minutes) on an empty stomach. The early experiments on alcohol metabolism were all carried out under this condition, and all the alcohol metabolism data we use today come from this. The alcohol content of wine can reach 0.02% (g/dl).
