Not only has alcohol been a controversial subject philosophically but also the scientific literature has been full of conflicting conclusions. Our knowledge of the absorption, distribution, and excretion of alcohol is well founded and generally accepted. The pathway of alcohol metabolism has been assumed on the basis of indirect evidence without much argument, but at the present time the exact pathway by which alcohol is metabolized is still uncertain.
