Ken Burns' excellent documentary miniseries Prohibition goes over this more in-depth in its overview of how disparate voting blocs banded together to accomplish the improbable -- passing a Constitutional amendment to ban alcohol.

It's also an eye-opener in revealing the historical origins of the expansion of police powers like wiretapping, and IIRC, overreaches of the Interstate Commerce Clause.

Once you've watched it, it's easy to draw some very damning "learn from history of be doomed to repeat it" parallels between Prohibition and the War on Drugs at a more detailed level than "drug prohibition doesn't work, just look at Prohibition."
