How long the human body take to eliminate alcohol?

It depends on your weight, how much alcohol is involved, and your rate of metabolism. Fat stores alcohol, that's why it seems that they can drink more and "hold it", but they will also release the alcohol slower into their bodies therefore. Skinny people use up the alcohol faster because they're not storing it up. I'm 5'10" and 120 pounds. I'm tipsy after 2, but I get sober before closing time if I've had four.
