How does one avoid the 'noble experiment' itself? By 1915ish, it was almost inevitable that national Prohibition was going to come about. Perhaps no WWI? IIRC, anti-German hysteria allowed the drys a lot of what they needed to go after the brewers, who happened to be mostly German. If there is no WWI or America doesn't enter the war, it's likely that it remains a contentious issue at the state and local level, but probably won't get far at the federal level.
Which likely means that even today we'd still have 'wet' and 'dry' states, barring a Supreme Court decision on the matter. Still, the potential butterflies are interesting. A weaker 'Bureau of Investigation' that might not end up being headed by a certain J. Edgar Hoover, a different American auto scene (slower cars?), less interstate regulatory apparatuses and law enforcement? What might this have on other restrictive drug laws?
