I have a question I want to add, if that's alright. There are some countries that handled the issue of prohibition during the same period, which I think could offer potential insight into the global issue of alcohol faced at the time.

There are more countries listed on Wikipedia here, but to name a few:

Canada: (1916-1920's)

Norway: (1916-1927)

Finland: (1919-1932)

My question is, why did these countries all face the issue of prohibition relatively around the same time period? What different solutions did these countries find?

For countries such as Canada, The Bahamas, and Cuba, Prohibition was seen as a positive boon. Enterprising Canadians like Samuel Bronfman made a fortune on smuggling Canadian Whiskey into the East. The Bahamas became a haven for rumrunners like Bill McCoy who got their alcohol and set up shop in Rum-row just beyond the limits of maritime law in major cities like New York and Boston. Cuba became a hotspot for wet tourists both through the air (via Pan-American Airways) and the sea (this time period saw the rise of the Cruise industry). Facundo Bacardi made the most of the opportunity presented by these visitors by offering passengers a tour of his distillery.

If you are interested in reading more about Prohibition's effects outside of the United States I would highly suggest the chapters in Daniel Okrent's Last Call: The Rise and Fall of Prohibition entitled "Leaks in the Dotted Line" and "The Great Whiskey Way" as well as Tom Gjelten's Bacardi and the Long Fight for Cuba
