Acetaldehyde

Alcohol is oxidised to acetaldehyde and than probably to acetyl-CoA. Drugs are like hundreds of types, so you must specify or read my previous posts ;)

That should be NAD H as a required cofactor for the reduction. NAD would be used for the reverse reaction (ethanol oxidation to acetaldehyde).

... product is CH3CH2OH. This is not a typical bio chemical reaction involving ethanol, though. More typical would be the ADH-catalyzed reduction of acetaldehyde to ethanol with NAD as a required co-factor. (ADH = alcohol dehydrogenase) Should also point out that the chemical reaction you've listed ...
