There was a recent case study done that determines that there are people who can get drunk from eating carbs. People explains that Auto-brewery syndrome “causes someone to become drunk without consuming alcohol due to excessive fermentation in the gut.” This recently happened to a man studied in this case.
The 46-year-old was arrested for drunk driving with a blood alcohol content of 0.2 percent. His aunt, who had heard of a situation like this before, bought the man a Breathalyzer to track his levels. He was eventually able to prove his innocence.
Through tests, they were able to figure out that his condition was most likely caused after a 2011 thumb injury. The antibiotics he was given altered his digestive tract. Since discovering his problem, the man has been able to repair his intestinal microbiome using probiotics, adjusting his diet, and occasionally checking BAC levels.
