Prohibition was more successful than we like to think. It did cut the level of drunkedness and —mtw—really reduced drug use. THAT didn’t come back until the ‘50s because of the stigma. Paradoxically drinking madea comeback because the gansterism made is respectable again among the middle-classes who had caused prohibition in the firstplace. Let is not forget that prohibition was a PROGRESSIVE reform.
It also gave Bonnie and Clyde another street-battle thing to get involved in (though bank robbing was their main affair). Amazing how little bathtub beer was served in speakeasies and blind tigers. It was whiskey, and the battles over it were bloody.
