Under what basis does the Catholic Church condemn the use of drugs while permitting alcohol?

> The use of drugs inflicts very grave damage on human health and life. Their use, except on strictly therapeutic grounds, is a grave offense. CCC 2291 > Let me state this in the clearest terms possible: the problem of drug use is not solved with drugs! Drug addiction is an evil, and with evil there can be no yielding or compromise. To think that harm can be reduced by permitting drug addicts to use narcotics in no way resolves the problem. Attempts, however limited, to legalize so-called “recreational drugs”, are not only highly questionable from a legislative standpoint, but they fail to produce the desired effects. Substitute drugs are not an adequate therapy but rather a veiled means of surrendering to the phenomenon. Here I would reaffirm what I have stated on another occasion: No to every type of drug use. It is as simple as that. No to any kind of drug use. Pope Francis As we can see, the Catholic Church seems to firmly oppose the use drugs. But at the same time, the Catholic Church seems to permit moderate use of alcohol. This position spawns much controversy among both alcohol prohibitionists and drug legalization supporters because of the claims that from the medical point of view there are no traits that would distinguish ethanol from other drugs like heroine, LSD, opium, marijuana, etc. Indeed, according to these claims, ethanol is even more harmful and dangerous than some of the others drugs condemned by the Church like marijuana. Therefore, as per this line of argument, Vatican should either prohibit the use of alcohol as sinful (which is hardly possible for liturgical reasons and would require re-interpreting some biblical passages like the one about the Wedding in Cana) or cease implying that the use of other drugs is inherently evil. I find it hard to believe that this critique hasn't reached Vatican yet. Are there any documents or statements that would explain the Church's teaching on this subject?
