Note that the alcohol level continues to rise for at least 30 minutes after drinking has stopped. This is because it takes a while for alcohol to be fully absorbed into the bloodstream, causing this drinker's BAC to rise even more. It is based on the fact that blood alcohol concentration (“BAC”) levels continue to rise even after someone stops drinking. When someone consumes an alcoholic beverage, blood alcohol rises rapidly. It continues to rise until it reaches a peak level anywhere from 30 minutes to two hours later.
