According to research conducted in South Korea, adding dissolved oxygen to alcoholic drinks helps the imbiber sober up faster. The time taken for 1/3 of a liter of a 19.5% (39 proof) drink to metabolize to 0.0 BAC was reduced from 5 hours to about 4.5 hours with 25% dissolved oxygen added. The British are not amused. A spokeswoman for the British Medical Association was unimpressed. "We wouldn't want a situation where people drank more simply because they would recover quicker."
