Now let's see if I have this straight. Prohibition in the United States began in 1920 and lasted until 1933 banning all liquor sales in the United States. With one exception, when it was prescribed for medicinal purposes and sold through licensed pharmacies. There were about 20 Walgreens Pharmacies at the start of prohibition. By the end there were 400. Obviously no connection there whatsoever!
Please note this very legal Whiskey Bottle was prescribed on October 23, 1925. Take as directed. And at the bottom it says "FOR MEDICINAL PURPOSES ONLY Sale or use for other purposes will cause heavy penalties to be inflicted".
