Which country drinks the most alcohol? According to the WHO, Estonia drinks the most alcohol(almost 5 gallons per person, per year). In Africa, Nigeria stands out as having the highest alcohol consumption. According to a paper published in BMC Public Health, "It has been reported that alcohol is the most commonly used drug in Nigeria characterized by “heavy episodic drinking” . Alcohol consumption by females in Nigeria has been on the increase and this has been associated with civilization, globalization and the expansion of women's liberation in the country." It's interesting how alcohol consumption in Nigeria has taken on somewhat of a cultural significance.
In the Americas, alcohol consumption is pretty similar among countries. In North America, the United States consumes more than its Canadian and Mexican neighbors.
