An alcoholic beverage is a drink containing ethanol, commonly known as alcohol. Alcoholic beverages are divided into three general classes: beers, wines, and spirits.
They are legally consumed in most countries, and over 100 countries
have laws regulating their production, sale, and consumption.
In particular, such laws specify the minimum age at which a person may
legally buy or drink them. This minimum age varies between 16 and 25
years, depending upon the country and the type of drink. Most nations
set it at 18 years of age.
The production and consumption of alcohol occurs in most cultures of the world, from hunter-gatherer peoples to nation-states. Alcoholic beverages are often an important part of social events in these cultures. In many cultures, drinking plays a significant role in social interaction — mainly because of alcohol’s neurological effects.
Alcohol is a psychoactive drug that has a depressant effect. A high blood alcohol content is usually considered to be legal drunkenness because it reduces attention and slows reaction speed. Alcohol can be addictive, and the state of addiction to alcohol is known as alcoholism.
