The Merits of Prohibition?

I do not agree with social libertarians on the question of legalizing narcotics. I may want to decriminalize drug use. But legalization would do very heavy damage to this country -- particularly to young people. Indeed, I am only an inch or two away from supporting a reinstitution of the prohibition on alcohol. Our national experience in the 1920's clearly confirms that Prohibition created almost as many problems as it solved. But Prohibition did solve an awful lot of problems -- as cataloged below:

Benefits of National Prohibition
(Quoting E. Deets Pickett, who was Associate Editor of the American Prohibition Yearbook; the actual sources are unidentified.)
Wife beating and lack of family support decreased 82%
Drunkenness decreased 55.3%
Assault decreased 53.1%
Vagrancy decreased 52.8%
Disorderly conduct decreased 51.5%
Delinquency decreased 50.0%
Deaths due to cirrhosis decreased 50.0%
The number of inmates in jails and prisons decreased 75%, and many correctional institutions were closed entirely
General domestic complaints decreased by two-thirds
County hospital death rates were historically low
Alcohol became almost unavailable
Prostitution decreased
The national crime rate (excluding Chicago) declined 38%; in Chicago, the crime rate declined 25% (despite some well-publicized criminal events)
Savings accounts tripled
Insurance policies written doubled
Real estate values increased dramatically, due to home improvements
Families became better clothed
Attendence at churches and schools became more regular
Factory job attendence and job performance greatly increased
Demand for services at welfare missions decreased by half
(Ed. note: None of the above were demonstrably caused by Prohibition. There is only a temporal association of these events with Prohibition. But, taken all together, and also noting that these social indices rose toward their pre-Prohibition levels after Repeal, it is difficult to deny that National Prohibition was a beneficial influence on American society during the 1920s.)
