By doing this, you give your guests extra time to reduce the alcohol level in their blood before driving home. Remember that if a person leaves your party intoxicated, you could be held partially liable for any harm they cause to themselves or to others. Only time can reduce impairment. The only thing that can sober up an intoxicated person is time. Black coffee, fresh air, exercise, or a cold shower won't do the job.
Entertainment is an art and a responsibility.
Your duties as host extend to being aware of the alcohol consumption of your guests. In so doing, you will make sure that everyone has a great time from beginning to end. Under normal circumstances, the body can safely handle about one standard drink per hour. However, your size, how fast you drink, what you've eaten, how you feel, and whether you are a woman or a man affect how alcohol affects you. No matter which you drink, it's all the same to your body.
