Blood and oxygen travel fast to your brain.
The drugs that makes a person unconscious are able to reach the brain and act at certain receptors that regulate consciousness.
Anesthesia "knocks you out" so fast because of the way it is delivered into your body. Either you inhale the gases, which go to your lungs, or you get it through an intravenous plastic catheter in your vein. Either way, it goes to your brain really fast and that is why you fall asleep before you can count backwards from 100 to 90.
