How long can I drive after drinking？ Expert： drink a lot, don’t train for 24 hours.

　　Tomorrow is New Year’s Eve, and there are many gatherings of relatives and friends during the holidays. According to the characteristics of previous years, drunk driving will enter a period of high incidence. After drinking once, how often can I drive? I drank a little at noon. Is it feasible to drive at night? Yesterday, the reporter acted as a volunteer and conducted a test in the Beijing Traffic Management Bureau: in the nearly six hours after drinking white wine and beer respectively, among the six volunteers, the alcohol content in 100 ml of blood dropped the most to 51 mg and the least to 32 mg. Dr. Yang Jinkui, director of the Endocrinology Department of Tongren Hospital, told reporters that considering the different metabolic capacity of each person, if you drink a lot at a time, you should wait at least 24 hours before driving.

　　Volunteer 1 159/148/147/121/109 400 ml of 53 spirit.

　　Volunteer 2 91/130/126/115/98 53 Liquor 400 ml.

　　Volunteer 3 132/142/129/113/100 200 ml of 53-degree white wine.

　　Volunteer 4 35/30/21/12/0 Beer 3 Listening

　　Volunteer 5 88/85/69/59/43 6 beers.

　　Volunteer 6 90/85/67/59/39 4 beers

　　Reporter pro-test

　　Physical differences are clear.

　　At noon yesterday, in the Traffic Management Bureau, Ao Xiang, a young policeman, walked past the reporter and five volunteers in turn with a rapid alcohol detection instrument. The detector sounded the sound of "thank you for your cooperation" for six consecutive times, which proved that the alcohol content in everyone’s body was zero at this time.

　　Immediately, the volunteers began to drink different amounts of liquor and beer respectively. An hour later, everyone came to an office of the Information Department of the Traffic Management Bureau to prepare for the first alcohol test. The reporter noticed that a computer on the desk is the terminal processor that processes all drunk driving data. Officer Dai Hu, a policeman from the Big Data Center of the Science and Information Department, told reporters that after the city’s traffic police distributed new alcohol testing equipment on October 16 last year, every time every traffic police conducted alcohol testing, the data would be uploaded here after seven or eight seconds and immediately displayed on the screen. Although it is noon at this time, it is obvious that there are still many traffic policemen on the front line who are busy checking alcohol, and the data list is updated from time to time.

　　Ao Xiang took out another device — — Exhaled gas alcohol content detector told reporters that in actual operation, the "quick check" equipment just now is used to check whether drinking alcohol or not, and then this equipment is used to accurately check "how much".

　　The reporter blew gently into the mouthpiece, and the detector sounded a sharp "beep" sound. After the sound stopped, Ao Xiang said, "You can stop." The reporter saw that the progress bar on the screen kept moving, but the results were not displayed.

　　"This situation shows that the driver is drunk driving or even drunk driving. The more you drink, the longer the device takes to calculate. " Ao Xiang told reporters. The voice just fell and the detector showed: 159. Then, on the computer screen behind him, a line of red font suddenly appeared, which recorded the detection information.

　　Dai Hu said that as long as the alcohol test for drivers meets the punishment standard, all information will be recorded in real time and there are corresponding legal documents. If the breath test shows that it is more than 80 mg and reaches the drunk driving standard, the system will automatically start counting the time. Within the specified time, blood tests must be carried out, and the system will automatically supervise the next work process of the police in terms of procedures, timeliness and other details, so as to standardize law enforcement.

　　While waiting for the next test, Yu Jiaji, a safety policeman of Chaoyang Traffic Detachment, told reporters that the status of volunteers after drinking was obviously different from that before the activity began. "Some of you are a little drunk, and some of you feel quite awake, but in our traffic police’s view, it’s all ‘ Gao ’ Well, no matter how confident you are now, believe that your mind is still clear. As long as this energy is used in driving, something will happen. "

　　Yu Jiaxuan told the reporter: "When the driver reacts to the situation ahead, it usually takes 0.45 seconds for emergency braking at normal speed; After drinking, the reaction time will increase by 0.2 seconds to 1 second. It doesn’t sound like much, but drivers know how many things can happen within 1 second. "

　　During many tests until 6: 00 pm, the physical differences of the volunteers were clearly shown: some of them declined slowly, others rose first and then fell, and all three people in the liquor group were under the standard of "drunk driving"; Of the three people in the beer group, two dropped from drunk driving standard to ordinary drunk driving, and the other quickly metabolized alcohol to zero.

　　Expert interpretation

　　Heavy drinking takes 24 hours to complete metabolism.

　　"The time of alcohol metabolism in the human body is related to the alcohol metabolizing enzymes determined by age, weight, health, liver and kidney function, and heredity, so it is very different and cannot directly represent everyone’s specific situation." Director Yang Jinkui of the Endocrinology Department of Tongren Hospital told reporters that many people think that alcohol consumption is related to mood, and it is easy to get drunk when they are in a bad mood, but this is mainly the influence of mood and has nothing to do with alcohol content in the body.

　　Yang Jinkui said that the time of metabolism is directly related to the alcohol concentration. The lower the alcohol concentration, the faster the metabolism. In this experiment, the person who drank the least among the volunteers finished metabolism in the shortest time, which also verified this point. "The more you drink, the longer it takes you to save alcohol, so it’s really directly related to the amount you drink to say how long you don’t touch the steering wheel. According to the general principle, it takes 24 hours after drinking a lot. If it is a small amount of drinking, it will take 12 hours for insurance reasons. "

　　As for why people who drink beer metabolize faster, Yang Jinkui said that it is very simple because the concentration of pure alcohol intake is lower. "The public may still have a misunderstanding. They think that after drinking wine, they should stay for a while. Even if the alcohol concentration is not low, the alcohol has gradually dropped, which may have less impact on normal work. However, from our point of view, if the same person’s alcohol content is 80 mg per 100 ml, one situation is that he has just finished drinking and is in a state of excitement, and the other is that he has been drinking for several hours. ‘ Exposure time ’ Different. Many people may think that after drinking for a few hours, the risk is reduced. In fact, from a professional point of view, on the contrary, the latter has a more obvious impact on people’s judgment and responsiveness. Therefore, whether it is during the Spring Festival holiday or at ordinary times, there is no uniform standard for when you can drive after drinking. After drinking, you must be patient for a while to make sure. " Reporter An Ran He Jianliang photo
