The change of alcohol content in blood after drinking can only be calculated with great probability: the alcohol content in blood reaches its peak about 40 minutes after drinking, and the half-life in the body is generally three hours. According to theoretical calculation, a person weighing 70kg should not get drunk after nine hours in theory, but to be on the safe side, he should drive after 10 hours.
