The intensity, type and effect of alcohol is very different in each person, therefore the speed of consciousness is also different in different people. Parameters such as gender, eating and drinking water can affect the time it takes for a person to sober up after consuming alcohol. Frequent drinking of alcohol may also increase the duration of sobriety. The duration of alcohol in human saliva also takes about 1 to 2 days, and the presence of alcohol in it can be detected by saliva testing. Routine urine tests detect the presence of alcohol in a person’s urine for approximately 2 days. Even some tests can determine the presence of alcohol in urine for up to 80 hours. Also, alcohol will remain in breast milk for about 2 to 3 hours with each glass of alcoholic drink.
