                                While the immediate effects can begin within 10 to 15 minutes, the peak blood alcohol concentration from 40% whiskey often takes between 30 and 90 minutes to be fully realized, depending on numerous physiological and situational variables. This means the initial 'buzz' is often just the beginning of the alcohol's impact on your system.
