The legal drinking age varies across the world. In the United States, the minimum legal drinking age is 21, with the exception of Puerto Rico and the Virgin Islands, where the age is 18. This law was passed in 1984, and since then, there has been a decrease in underage drinking and drunk driving rates among teenagers and young adults. Other countries, like Canada, have a minimum drinking age of 19, while some countries have no laws restricting the sale of alcohol to minors. The legal drinking age is a controversial topic, with some arguing that it should be lowered to 18, as that is when individuals gain several other rights, such as voting and serving on juries. However, others argue that a minimum legal drinking age of 21 helps reduce alcohol consumption and the risk of alcohol-related harm, especially among young people.

Alcohol and brain development
The minimum legal drinking age is 21 in the United States, with the exception of Puerto Rico and the Virgin Islands, where the age is 18. In Canada, the minimum age is 19, except in Alberta, Manitoba, and Quebec, where it is 18. In Europe, most countries have set the minimum age to purchase alcohol at 18.
The brain continues to develop into a person's mid-20s, with the prefrontal cortex and hippocampus typically becoming fully developed by the mid-twenties. This period of brain development increases the adolescent brain's vulnerability to alcohol exposure. Research has shown that alcohol consumption can negatively impact brain development in adolescents and young adults, with indications that the gray matter of the brain develops abnormally in young people who drink. This abnormal development can lead to an increased risk of developing alcohol use disorder (AUD) later in life.
The prefrontal cortex, which helps control impulses, is not fully developed in teenagers, making it more difficult for them to resist the urge to drink alcohol. Alcohol floods the brain's reward circuits with dopamine, and the sensitivity to this dopamine encourages teens to drink more. Binge drinking is particularly harmful to adolescent brain development and can lead to long-term or irreversible effects on the teenage brain.
Functional MRI scans have shown that heavy drinking can alter the brain activity of teenagers, impacting their ability to learn and process information. Studies have also found that alcohol impairs the cognitive abilities of young adults (aged 21-24) more significantly than those in their late twenties, with the younger group experiencing greater difficulty in learning and processing new material.
Underage drinking is associated with various risks, including an increased likelihood of smoking, using drugs, and engaging in high-risk sexual behavior, and experiencing academic difficulties. It can also lead to alcohol dependence, suicide, homicide, and serious pregnancy complications. Therefore, it is recommended that adolescents and young adults refrain from consuming alcohol to support healthy brain development and overall well-being.

Alcohol-related deaths
In the United States, you must be 21 years old to handle alcohol. This means that alcohol cannot be sold to anyone younger than 21. Most state laws require a picture ID or government-issued identification card to purchase alcohol. While the legal drinking age varies by state, the minimum legal age to purchase alcoholic beverages is 21 years old in most states.
The National Minimum Drinking Age Act of 1984 imposed a reduction of highway funds for states that did not increase their minimum legal drinking age to 21 years. All states complied and implemented this minimum legal drinking age by 1988. Since the law was passed, underage drinking rates have dropped significantly. From 1985 to 1991, the percentage of young people (aged 18 to 20) who reported drinking alcohol during the past month decreased from 59% to 40%. The law also helps prevent young people from becoming dependent on alcohol and drugs, lowers the risk of suicide and homicide, and reduces the likelihood of serious pregnancy complications.
Despite these preventative measures, alcohol-related deaths have surged in recent years. In 2022, 105,415 Americans died due to alcohol-related causes, a 29.3% increase from 2016 to 2021. Alcohol poisoning deaths have skyrocketed by 45.9%, indicating a rise in binge drinking behavior. Adults aged 55–64 years had the highest alcohol-related death rates, while young adults (18–24) had the lowest death rates. However, excessive alcohol use remains prevalent in this younger demographic. Drunk driving is a leading cause of preventable deaths, with alcohol-impaired driving causing 13,524 deaths in 2022, accounting for 32% of all traffic fatalities.
Heavy drinking is linked to 3,500 deaths among people under 21 every year. Underage drinking increases the likelihood of smoking, drug use, high-risk sexual behavior, suicide, sexual assault, and alcohol dependence later in life. It can also cause brain development issues and poor school performance.

Underage drinking is a major public health issue and can lead to serious health and safety risks, including death. It is linked to 3,500 to 5,000 deaths among people under 21 every year. Underage drinking may also cause brain development issues, poor school performance, and higher rates of school absences.
