Interesting to see the BAC levels that constitute drunk driving in different countries. I think when I first was able to legally drink the BAC was .10 and now it is .08.
The amount of alcohol one can consume is related to weight. The more you way, the more you can drink before getting drunk. Men can handle more alcohol than women and this is made worse since women on average way less than men.
Here is chart that show how much alcohol a man can drink before getting to .08.
What is a drink?
...one drink equals 1.5 ounces of 80 proof liquor (40% alcohol), 12 ounces of beer (4.5% alcohol), or 5 ounces of wine (12% alcohol).
Here is a chart for women:
Those charts were from,
Drinks Before Driving If BAC Is .05 - Business Insider.
The rule of thumb I have heard for years is that it takes a man about one hour for his body to metabolize one drink. A woman metabolizes a bit less in one hour. The metabolism is dependent on weight as well as gender.
Here is what is important about the body metabolizing booze....
Let say someone started drinking at 2:00pm and drank two beers every hour. At the end of one hour, 3:00pm, the man would have drank two beers but one had been metabolized so one beer remains in his body.
From 3:00-4:00pm the man drinks two more beers, one gets metabolized but one is left in the body so the man has a total of two beers in his body. From 4:00 to 5:00pm two more beers are drunk, one metabolized and the one is retained for a total of three in his body.
If the man weighs 140 pounds he is legally drunk in the US. At 160 pounds he would not be legally drunk but he is close. A woman under 180 pounds who was drink two drinks an hour would be legally drunk in the US.
I think this how many people get drunk. They don't sit down and pound down a six pack in an hour but just drink a couple beers hour after hour during the afternoon and/or evening. They think they are drinking responsibly but eventually the alcohol saturates the system and they go over their limit.
