What should my son do when he goes home for the New Year and drinks outside all day?

You can give oral education on the dangers of drinking.

Tell your son that drinking is harmful to people's health. For example, the damage to the liver is very great, because drinking is metabolized by the liver. Drinking too much can damage the liver, which is very harmful to the body, leading to chronic alcoholism and alcoholic cirrhosis. If you usually have hepatitis B virus and drink a lot, it will easily spread into liver cancer. There may also be brain diseases, such as hypertension, hyperlipidemia and diabetes, and then long-term drinking and heavy drinking can easily lead to diseases such as arteriosclerosis, cerebral hemorrhage and cerebral infarction.

The effective component of wine is alcohol, and its chemical name is ethanol. When ethanol enters the human body, it will have many destructive effects.
