A woman in the United States has escaped a drink-driving charge — after proving that her body is a natural "brewery." The woman, who has not been named, was arrested in New York state in 2014 after being pulled over for erratic driving and found to have a blood-alcohol level more than four times the legal limit. The woman, said to be a 35-year-old school teacher, was referred for medical tests which revealed that even after a day drinking no alcohol at all she had a blood-alcohol content of 0.36 per cent compared with the New York "drunkenness" threshold of 0.08 per cent. She was subsequently diagnosed with a rare condition called auto-brewery syndrome.
