The term "underage drinking" refers to consuming alcohol by individuals who have not yet reached the legal age for doing so, which varies depending on jurisdiction. In most countries, the legal drinking age is 21 years old; however, in some places it can be lower at 18 or even 16 years of age. Underage drinking is considered a serious offense and carries penalties such as fines, community service, or educational programs. The practice has been linked to various negative consequences including health problems, academic difficulties, and increased risk-taking behavior.
