The wine used in this experiment

September 1, 7:40 pm or so, Qingchun Road 145 road section of the west-to-east lanes, a cab and a private car friction. The accident is not big, but traffic police at the scene found that the cab driver had a clear smell of alcohol. Blow test with an alcohol tester, the results of 1.51mg/ml, the driver Huang has been suspected of drunk driving; subsequently, Huang was taken to the hospital for a blood alcohol concentration test, the results were 1.6mg/ml.

Huang insisted that only half a catty of yellow wine in the noon, alcohol should have long passed, "know that you can't drive after drinking, but I don't know to drink well! Four or five hours there is such a high concentration of alcohol."

Huang said, he did a good job on the night shift on September 1, one or two o'clock, parked the car to go eat late-night snacks, beer to quench their thirst, two bottles of the least. Go home and woke up close to noon, it fried a plate of pike crabs, half a catty of yellow wine, half an hour under the belly, continue to sleep; 5 p.m. to hand over the shift, dinner on the outside casually eat a little bit more than 7:00 p.m., was checked by the police.

Earlier news: "are after four or five hours how still high a night shift brother suspected of drunk driving"

Yesterday, many readers read this news, said they do not believe the drunken driver's own statement - a person who often have to drink some wine, half a kilogram of yellow wine at noon, to the evening can still measure the "drunk driving"? This wine, I'm afraid, will not be drinking at noon!

Reader Mr. Qiu also proposed: I think the Express can not do an experiment? Organize a few people, each drink two bottles of beer, do an alcohol test, and then after a period of time and then test again, and ultimately tell everyone a result, how many hours after the drink to do the test to not contain alcohol? Because a lot of people around me, after drinking, think that if they rest for a while, they will be fine, so how long do they really have to rest before they are fine?

Li Li An, deputy director and deputy chief pharmacist of Hangzhou Normal University Hospital (City No. 2 Hospital), is well versed in the body's reaction to various chemicals; Dr. Zhu Shibing, a physician at the emergency room of the Hangzhou Honghui Hospital, is experienced in treating patients with alcohol poisoning.

Through interviews with these two experts, we try to restore the process of alcohol from the entrance to the exit of the body in layman's terms and analyze the effects on every aspect of the human body.

Dr. Li Li'an and Dr. Zhu Shibing both said the rate of alcohol metabolism depends on many factors, and there is no fixed value for how long it takes for alcohol to evaporate after drinking.

The higher the alcohol content, the faster it is absorbed and the slower it is removed from the body. Beer = 4 to 6 percent (that is, divide a bottle of beer into 100 parts and the ethanol content is four parts); wine = 7 to 15 percent; champagne = 8 to 14 percent; and spirits such as whiskey = 40 percent or more.

The main absorption pathways of alcohol

After alcohol is ingested → 20% is absorbed in the stomach → 80% is absorbed in the small intestine;

After that, the alcohol enters the blood system → the blood carries the alcohol through the body and circulates it → it enters and dissolves into the various tissues of the body and produces effects.

The main pathways of alcohol elimination

After alcohol is absorbed by the blood system → the liver breaks down the alcohol into acetic acid → the kidneys excrete 5% of the alcohol through urine → the lungs exhale 5% of the alcohol → in addition, some of the alcohol evaporates through the pores of the skin, etc.

After that, alcohol enters the blood system and is absorbed into the bloodstream.

How much time does it take to metabolize alcohol

Blood alcohol concentration rises significantly within 20 minutes after drinking.

According to foreign experiments, the average person can digest 15 milliliters of alcohol per hour, which translates to about one hour to digest 355 milliliters of alcohol in beer.

According to Dr. Zhu Shibing's clinical experience in saving lives, the average person who drinks 1 bottle of beer can still have a measurable amount of alcohol in his bloodstream, usually within 2 hours.

Cocktails are easier to get drunk

Cocktails are a variety of alcohol mixed together, or add carbonated drinks, these will speed up the absorption of alcohol, people get drunk faster.

Drinking on an empty stomach is also easy to get drunk because food slows down the absorption of alcohol in the gut.

The more biochemical enzymes you have, the less likely you are to get drunk

This has something to do with a person's genetics. There is a biochemical enzyme in the liver called alcohol dehydrogenase that strips electrons from ethanol to form acetaldehyde, which is converted to acetic acid. Acetic acid can be used to form fatty acids, which are further broken down into carbon dioxide and water and exhaled or excreted.

The more biochemical enzymes you have, the faster you can break down alcohol.

Women are more likely to get drunk than men

Men and women of the same height, weight and build are more likely to get drunk than men.

Because men have more muscle and women have more fat. There is more water in muscle tissue than in fat tissue, so after absorbing an equal amount of alcohol, the dilution of alcohol in a man's body is better than a woman's.

In addition, alcohol can be evaporated out of the body through the skin on the surface of the body, and people who are bigger have a larger skin area and metabolize alcohol faster.

And the better the gastrointestinal power, the faster the alcohol metabolism.

Vomiting within 2 hours after an overdose is good for the body

Dr. Wang Xiaoping of the 92nd Hospital of the Chinese People's Liberation Army (PLA) has a paper, "Rescuing 52 Cases of Acute Alcohol Poisoning," which was published in the Fujian Medical Journal, 1995, Vol. 17, No. 4. The paper says:

52 cases of acute alcohol poisoning, cured 44 cases, leaving 5 cases of central nervous sequelae, liver damage 1 case.

The two cases of death were both 16-18 hours after poisoning, and resuscitation was ineffective, dying of respiratory and circulatory failure. The study concluded that the lethal dose of pure alcohol is 250-500 ml for adults; about 25 ml for children. All of it can be absorbed into the bloodstream 2 hours after drinking.

Dr. Zhu Shibing said, for the diagnosis of alcohol poisoning, usually will wash the stomach, vomiting, catheterization, diuresis, injection of antidotes. Fluids are given in saline or glucose to balance electrolytes. Some people vomit after drinking, which is a human instinct to protect the body. Vomiting within 2 hours after excessive drinking is good for the body.

Special reminder

Because of the different personal constitution, different drinking habits, and drinking water, vomiting and other factors after drinking, the data of this experiment is for reference only, and is not a guide. Driving is not drinking, drinking is not driving, and keeping this in mind is the safest thing to do.
