“The best evidence available to historians shows that consumption of beverage alcohol declined dramatically under prohibition. In the early 1920s, consumption of beverage alcohol was about thirty per cent of the pre-prohibition level. Consumption grew somewhat in the last years of prohibition, as illegal supplies of liquor increased and as a new generation of Americans disregarded the law and rejected the attitude of self-sacrifice that was part of the bedrock of the prohibition movement. Nevertheless, it was a long time after repeal before consumption rates rose to their pre-prohibition levels. In that sense, prohibition ‘worked.’” -from prohibition.osu.edu
