Alcohol Consumption: Is It Safe For 18-Year-Olds?

Alcohol is the most popular drug among teenagers and young adults. While the legal drinking age in most countries is 18, the United States and a few other countries have set it at 21. Proponents of maintaining the legal drinking age at 21 argue that it helps lower the risk of developing alcohol and other substance use disorders, while opponents argue that it causes unsafe alcohol consumption among teenagers who want to drink.

Alcohol's effects on the brain and body

Alcohol affects the brain and body in several ways. Firstly, it interferes with the brain's communication pathways, affecting areas that control balance, memory, speech, and judgment. This interference can result in injuries and other adverse outcomes. Long-term heavy drinking can lead to structural changes in the brain, including reductions in neuron size. Adolescent brains are particularly vulnerable to the negative effects of alcohol, and misuse during this period can lead to long-lasting alterations in brain development and function.

Alcohol has a dual reinforcing effect on the brain. It can activate the brain's reward system, creating a pleasurable experience, while simultaneously reducing activity in systems that mediate negative emotions such as stress, anxiety, and emotional pain. This dual effect can lead to the development of addiction, characterised by reduced reward function and increased activation of brain stress systems. The addiction cycle involves three stages: binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation.

The binge/intoxication stage involves drinking heavily to activate the brain's reward circuits and experience pleasure. The withdrawal/negative affect stage is motivated by attempts to reduce the emotional discomfort associated with withdrawal. Finally, during the preoccupation/anticipation stage, individuals may drink to self-medicate conditions like high impulsivity.

Excessive alcohol consumption can also have detrimental effects on the body. It can weaken the immune system, making individuals more susceptible to diseases like pneumonia and tuberculosis. Additionally, drinking can increase the risk of heart problems, liver inflammation, and cancer. Binge drinking, which involves consuming large amounts of alcohol over a short period, can lead to immediate and severe intoxication, resulting in hangovers, alcohol poisoning, accidents, and violence.

The negative consequences of alcohol consumption can be mitigated by low-level drinking or abstinence. Pacing drinks and staying hydrated by drinking water between alcoholic beverages can also help reduce the severity of hangovers. However, for some individuals, abstinence may be the safest option to avoid alcohol-related harm.

Legal drinking age

The legal drinking age varies across the world. In the United States, the legal drinking age is 21 years old. This means that it is illegal for anyone under the age of 21 to purchase or publicly consume alcohol. However, in 61% of other countries, the drinking age is between 18 and 19 years old.

There are differing opinions on whether the legal drinking age should be lowered to 18 in the United States. Some argue that 18-year-olds are mature enough to handle alcohol and that lowering the drinking age would allow teenagers to consume alcohol responsibly, rather than hiding it from parents and authorities. Additionally, at the age of 18, individuals in the United States are considered legal adults and gain several privileges, such as the right to vote, buy tobacco products, get married, work full-time, and serve on jury duty. It is argued that if 18-year-olds can make life-altering decisions, such as enlisting in the military, they should be allowed to legally consume alcohol.

Furthermore, some believe that prohibiting drinking for teenagers may actually increase the risk of unsafe alcohol consumption. Dr. David J. Hanson, a sociologist at the State University of New York, states that when teens know they are not allowed to drink at an event, they may consume large amounts of stronger alcohol beforehand, leading to dangerous levels of intoxication and an increased risk of alcohol poisoning.

On the other hand, supporters of maintaining the legal drinking age at 21 argue that it helps lower the risk of developing alcohol and other substance use disorders. Raising the minimum legal drinking age has been associated with a decrease in drunk driving fatalities and a reduction in the percentage of young people who drink alcohol. Additionally, it supports families and communities by leading to fewer harmful births, lower rates of suicide and homicide, and fewer deaths from alcohol poisoning.

While there are valid arguments on both sides of the debate, the legal drinking age in the United States remains at 21, emphasizing the potential risks and negative consequences associated with underage drinking.

Alcohol-related deaths

In the United States, the legal drinking age is 21, and experimentation with alcohol during the teen years is common. Alcohol is a depressant that slows down the central nervous system, altering a person's perceptions, emotions, movement, vision, and hearing. While small amounts can help a person feel relaxed or less anxious, larger amounts can cause intoxication, leading to staggering, loss of coordination, slurred speech, confusion, disorientation, and dramatic reaction time delays.

Two-thirds of alcohol-related deaths, or about 117,000 deaths, are from chronic conditions that develop over time. These include several types of cancer, heart disease, liver disease, and alcohol use disorder. The remaining one-third, or about 61,000 deaths, result from binge drinking or acute alcohol consumption, including motor vehicle crashes, alcohol-involved drug overdoses, alcohol poisoning, and suicides. Alcohol-related suicides are of particular concern, as Alcohol Use Disorder (AUD) is the second most common mental disorder among suicide victims.

To address this issue, policies that reduce alcohol availability, accessibility, and price could help decrease excessive alcohol consumption and related deaths. Additionally, educating teens about the dangers of alcohol and providing support for those struggling with alcoholism or living with alcoholic family members are crucial.

Underage drinking laws

In the United States, the legal age to purchase or publicly consume alcohol is 21. This is based on the National Minimum Drinking Age Act that was passed in 1984. Under this Act, states are required to enforce a minimum drinking age of 21 to receive certain types of federal funding. While most states adhere to this minimum legal drinking age (MLDA) of 21, there are some local and state-based exceptions. For instance, some states allow exceptions for religious activities or with the consent of a parent, spouse, or guardian in specific locations. However, no state exception permits anyone other than a family member to provide alcohol to a minor on private property.

Many states have "social host" laws that hold the person who owns, leases, or controls a private property liable for any minors who engage in underage drinking on their property, regardless of whether they provided the alcohol. Ten states have "social hosting" laws that specifically prohibit hosting underage drinking parties, while another 21 have general "social host" laws. This means that 31 states do not have specific "social host" laws regarding underage drinking events on private property.

Underage drinking is a serious public health concern, contributing to thousands of deaths each year and increasing the risk for accidents, injuries, and addiction later in life. To address this issue, states like Florida have strict laws prohibiting the sale, provision, or service of alcohol to individuals under 21, with exceptions for religious ceremonies and accredited educational purposes. Violating these laws can result in severe consequences, including fines, jail time, and legal liability if minors cause injury or damage property while under the influence.

In South Carolina, underage drinking costs the state $1 billion annually, with 23.1% of students in grades 9 through 12 having consumed alcohol in the past month. To combat this, South Carolina's Alcohol Enforcement Teams (AETs) collaborate with law enforcement and prevention professionals to enforce underage drinking laws and educate the community about the dangers of underage alcohol consumption. The state also imposes strict penalties on adults who provide alcohol to minors, including fines, jail time, and liability for any harm or damage caused by intoxicated minors.

Alcohol consumption patterns

Proponents of maintaining a minimum legal drinking age of 21 years in the United States argue that it helps lower the risk of alcohol and substance use disorders, reduces harmful births, lowers suicide and homicide rates, and mitigates alcohol poisoning deaths. Research shows that after states raised their minimum drinking age to 21 in 1984, there was a notable decline in alcohol consumption among young people. From 1985 to 1991, the percentage of 18- to 20-year-olds who drank alcohol in the past month dropped from 59% to 40%. Additionally, young adults in this age group drank less, with a decrease in monthly drinking from 70% to 56% during the same period.

However, critics of the current legislation in the United States argue that a lower drinking age, such as 18 years, could potentially enable teenagers to consume alcohol responsibly in controlled environments rather than hiding it from parents and authorities. Dr. David J. Hanson, a sociologist, suggests that prohibiting drinking for teenagers may push them towards uncontrolled environments, such as fraternity houses, where dangerous drinking games and rapid alcohol consumption pose a significant risk of alcohol poisoning. Additionally, Morris E. Chafetz, the founder of the National Institute for Alcoholism and Alcohol Abuse, challenges the notion that lowering the drinking age would lead to increased adolescent alcohol abuse or brain impairment.

The legal status of alcohol consumption for 18-year-olds also intersects with cultural and societal perceptions. In some cultures, alcohol is deeply integrated into social rituals, with many adults consuming beer or wine with meals. This normalization of alcohol can influence teens' perceptions, making it seem harmless to experiment with. Additionally, the advertising industry often portrays beautiful people enjoying life while consuming alcohol, further contributing to the allure for teenagers.

While the legal drinking age varies globally, it is essential to recognize the potential risks associated with alcohol consumption at any age. Alcohol is a depressant that slows down the central nervous system, altering perceptions, emotions, movement, vision, and hearing. Excessive alcohol consumption can lead to intoxication, with symptoms including staggering, loss of coordination, slurred speech, confusion, disorientation, and dramatic changes in behavior. Furthermore, drinking large amounts of alcohol in a short period can result in alcohol poisoning, which can be life-threatening.
