Times of a new book,
From its beginnings in the late 19th century, Coca-Cola was advertised
as a stimulant. In 1909 the federal government seized an interstate
shipment of syrup, charging that the beverage’s caffeine content
violated the Pure Food and Drug Act. It took five years for the
Coca-Cola Company to win that case, whereupon it promptly reduced the
amount of caffeine in the proprietary formula.
