Alcohol flush reaction?

How do those who have Alcohol Flush Reaction stop being drunk, biologically?

• There is a genetic defect called AFR, where individuals, usually Asian, lack acetaldehyde dehydrogenase. From what I understand, when a person drinks alcohol the process is: 1. Alcohol dehydrogenase turns alcohol into acetaldehyde 2. acetaldehyde dehydrogenase-2 turns the acetaldehyde into acetic acid 3. Other enzymes turn acetic acid into water and CO2 4. the liver processes the water and CO2 at a certain rate. Those not processed yet circulate the body, and thus give the intoxication effect. Is that right? If so, then if acetaldehyde dehydrogenase-2 is lacking do to the AFR mutation, then how do people get rid of the alcohol in their body? Furthermore, wouldnt that mean they would always be drunk. Or would it mean that they would never get drunk since acetic acid, and thus CO2 and Water, which is what gives the drunk feeling, is never produced from alcohol.

• Answer:

  It pretty much means you get drunker faster and with less alcohol than the average westerner.Not only that,but then you'd have higher risk of the bad effects of alcohol such as liver failure and esophageal cancer.That's all.You get the hangovers and the drunkedness wears off eventually like with everyone.
