Legal Drinking Age

The legal drinking age establishes the point at which individuals are authorized by law to buy and consume alcohol. This age varies worldwide, reflecting each country’s unique blend of cultural, societal and health-related factors. In the United States, individuals must be 21 to legally drink, a standard set by the National Minimum Drinking Age Act of 1984 in response to underage drinking concerns. This marked a shift from previous state laws that permitted alcohol consumption at 18.

In contrast, countries like South Africa and the UK permit legal alcohol consumption from the age of 18. South Africa’s current alcohol policies have evolved significantly from the rigid regulations of the apartheid era, aiming for fairness and public health improvement. The UK also allows drinking at 18 but continues to grapple with issues of underage and binge drinking, prompting initiatives to encourage more responsible alcohol consumption.

These examples illustrate the global diversity in legal drinking ages, each influenced by its historical, cultural and public health landscape.


In Africa, the legal minimum age for alcohol purchase is predominantly 18 years with Angola (excluding Luanda Province), the Central African Republic, Comoros, Equatorial Guinea, Guinea-Bissau and Mali lacking specific legislation regulating alcohol sales to minors. Countries like Libya, Somalia and Sudan enforce a total ban on alcohol sale, production and consumption.

The legal drinking and purchasing age across Central America, the Caribbean and South America ranges from 0 to 20 years. Notably, in South America, the standard legal age for purchasing alcohol is 18 with Paraguay setting both the drinking and purchasing ages at 20 years. Guyana allows minors aged 16 or 17 to consume beer or wine in a restaurant, given they also purchase a meal.


In Asia, the legal drinking age varies widely, reflecting the continent’s diverse cultural and legal environments. While many countries adhere to the global norm of 18 years for legal alcohol consumption and purchase, others like Japan and South Korea set the age limit at 20. Regions with strong religious influences, such as certain provinces in Indonesia, may impose stricter restrictions, whereas countries like China and India see variations within their borders due to regional autonomy. In contrast, some countries in the Middle East enforce complete bans on alcohol due to religious laws. Enforcement of these drinking age laws can range from strict to lenient, highlighting the complex interplay between traditional values, public health and legal regulation of alcohol across Asia.


In North America, the legal age for alcohol consumption and purchase varies from 18 to 21 years. Mexico uniformly sets the drinking age at 18 across all states. The United States generally requires individuals to be 21 to purchase alcohol, except in Puerto Rico and the Virgin Islands, where the age limit is 18. The drinking age in the United States can differ by state and some states allow supervised drinking with parents or guardians without age restrictions. Canada’s minimum age to buy or consume alcohol is mostly 19, except in Alberta, Manitoba and Quebec, where it is 18.

Historically, North America saw changes in its minimum legal drinking ages (MLDAs) in the late 20th century. In the 1970s, Canada and the United States lowered their MLDAs to align with the age of majority—18 years. However, Ontario and Saskatchewan later increased their MLDAs to 19 following studies linking lower drinking ages to increased alcohol-related harms. In the U.S., the National Minimum Drinking Age Act of 1984 was enacted, mandating states to raise their MLDA to 21 or face a reduction in highway funds. This led all states to comply by 1988.


In Europe, the minimum age to purchase alcohol is set at 18 in most countries with Austria, Belgium, Denmark, Germany, Gibraltar, Liechtenstein, Luxembourg, Malta, Portugal and Switzerland allowing minors limited access to alcohol under 18. Discussions to harmonize the minimum purchase age at 18 across the European Union took place in 2005, 2007 and 2015 but did not lead to agreement.

On the aggregate the legal drinking age aims to balance young adults’ rights and responsibilities with public health and safety concerns. The effectiveness of these laws depends on factors like law enforcement, public education and cultural attitudes towards alcohol. The primary goal in addiction recovery is to mitigate the harmful effects of early alcohol consumption on health and social outcomes.
