In female adolescent rats,bone density was reduced during a period of alcohol consumption, andafter cessation, bone growth resumed, but did not compensate for growththat had been lost during the alcohol ingestion period (Sampson and Spears,1999). Large quantities of alcohol consumed by young ratsresulted in weaker bones (Sampson, Perks, Champney, and DeFee, 1996). These findingsfrom animal models are supported by studies in humans showing thatalcohol drinkers tend to have less bone mineral density, especiallyadolescent males (Nevilleet al., 2002). Subacute effects of drinking may be experienced in the day or twofollowing an episode of heavy drinking. For adolescents, these effectscan include feeling dizzy when first standing up, nausea or vomiting,feeling depressed or irritable, tremor or shakes, racing heart,sweating, rapid breathing, insomnia, headaches, and muscle aches orweaknesses (Stewart andBrown, 1995; Tapert and Brown, 1999). Although relatively rare, youth whohave developed a physical addiction to alcohol can experience withdrawalseizures in the first few days of abstinence.
What are the long-term effects of underage drinking?
Young people under the influence of alcohol are at an increasedlikelihood of deciding to use other drugs (Brown, Tapert, Tate, and Abrantes,2000b). Youth who drink are significantly more likely to useother illicit drugs, compared to young nondrinkers (Kandel and Davies,1996). A young person may decide to use an illicit substanceafter drinking because judgment is impaired, exposure to othersubstances is more likely, and susceptibility to peer influences isamplified. Once alcohol use has been initiated, the use of otherintoxicants may no longer appear as risky to the teen. As BACs rise,alcohol overdose can occur, resulting in respiration failure,suffocation, coma, and, in some cases, death. Alcohol intoxicationproduces diminished inhibition, increased violent behavior, and poorjudgment that can result in being in the wrong place at the wrong time,and these factors all contribute to young deaths and injuries due toalcohol-related aggressive behavior.
What are the effects of teenage drinking on the brain?
Reaction times are slowed dramatically — which is why people are told not to drink and drive. People who are intoxicated may think they’re moving properly when they’re not. From there, teenagers and alcohol it affects the central nervous system (the brain and spinal cord), which controls virtually all body functions. Formerly known as alcoholism, alcohol use disorder (AUD) can affect people of all ages.
Statistics on alcohol use in teens
- Without treatment, youth who drink excessively as teenagers are more likely to become problem drinkers than adults.
- This region is responsible for higher-order thinking – which includes emotional regulation, decision-making, and self-control.
- Alcohol poisoning is exactly what it sounds like — the body has become poisoned by large amounts of alcohol.
- The team also ran an online experiment on different types of messaging through a social marketing advertising campaign for adolescents aged 18 to 19.
University of Adelaide’s Dr David Jaud from the Adelaide Business School explains that communication should be genuine and balanced to provide effective messaging to reduce excessive drinking behaviour in adolescents. Dr. Jaud says adolescent behavior is complex, particularly when it comes to alcohol consumption, and navigating the best way to communicate safe drinking is equally challenging. University of Adelaide’s Dr. David Jaud from the Adelaide Business School explains that communication should be genuine and balanced to provide effective messaging to reduce excessive drinking behavior in adolescents. It’s common for parents to think that if they allow their teenager alcohol in moderation while they’re in a safe environment, such as a glass of wine with dinner at home, this will lead to a better relationship with alcohol. Parents should actively encourage their teenager to delay drinking any alcohol for as long as possible. Additionally, the NIAAA notes that people who start drinking before age 15 are more than three times as likely to develop AUD as an adult than people who waited until age 21 to start drinking.
Instead, MacKillop suggests adolescents could be provided with better education about alcohol’s risks, and the ways that it can affect the maturing brain. “Just assuming that people will naturally develop responsible habits when it comes to these drugs is a fairly optimistic assumption,” he says. It is becoming increasingly evident that the comorbidity of AUD andother mental health disorders is one of the most prevalent andimportant challenges facing professionals treating youth withalcohol problems today. According to a recent review, in the 1990s morethan 125 studies were published focusing on alcohol and drug usedisorders and comorbid mental health problems. Late adolescent male rats given alcohol and physicalexercise showed reduced bone formation rates, suggesting an increasedchance of exercise-related bone injuries in young drinkers (Reed, McCarty, Evans,Turner, and Westerlind, 2002).
- The widespread changes in the organization and functioning of the brain—which continue into a person’s mid-20s—bring about the cognitive, emotional, and social skills necessary for adolescents to survive and thrive.

- Taking alcohol with other drugs that also suppress the central nervous system (such as heroin and benzodiazepines) can be particularly risky.
- The result is a more efficient neural network that can process information more quickly.
Homicide is the second leadingcause of death for those ages 10 to 20 (National Center for Health Statistics,1999). Suicide is the third leading cause of death for youth(National Center forHealth Statistics, 1999), and approximately 28 percent ofsuicides of those 9 to 15 years old can be directly attributed to or arerelated to alcohol use (Preuss et al., 2002; Reifman and Windle, 1995). An earlier exposure to alcohol also puts teenagers at risk of developing a dependency later in life. “A lot of people describe the adolescent brain as having a fully developed gas pedal without brakes,” Squeglia previously explained to the BBC. According to statistics cited by Drinkaware, teenagers who engage in binge drinking put themselves at a greater risk of negatively impacting their concentration and learning. Booth said that normalizing the taste, experience, and habit of drinking could lead teens to an interest in trying the alcoholic version of beverages.
ACUTE EFFECTS
With that said, some research suggests that people who drink alone as teenagers are likely to develop AUD as drug addiction treatment adults. Although binge drinking can have negative health consequences, not all people who binge drink are necessarily addicted to alcohol. As adolescents mature, they undergo complex developmental changes, especially in their brains. The widespread changes in the organization and functioning of the brain—which continue into a person’s mid-20s—bring about the cognitive, emotional, and social skills necessary for adolescents to survive and thrive.
Alcohol can impair brain development
The prevalence of these etiological pathways variesacross types of mental health disorders and specific drugs ofaddictions. These connections, or synapses, are small gaps betweenbrain cells across which specific brain chemicals travel. However,not all these connections are necessary and, in fact, unneededconnections slow brain activity. Throughout childhood and intomid-adolescence until roughly age 16, these unneeded connections areeliminated, leaving the brain a more refined system (Huttenlocher,1979) with which to interpret sensory information,conduct thinking, and coordinate motor responses. A relateddevelopmental process that continues into adolescence is thefunctioning of brain chemicals or neurotransmitters (Silveri and Spear,2002).

For this reason, it is important for parents or caregivers, schools, and communities to know the risks and address education about alcohol among young people. The National Institutes of Health (NIH) emphasizes that a caregiver’s attitude toward alcohol and teen drinking can significantly affect the likelihood of their child drinking. To an extent, this is typical for this life stage, as teens begin to enter the world of adulthood and try new things. But in combination with alcohol, which also lowers inhibitions, it can result in impaired judgment.
Both countries see an increase in binge drinking after someone has passed the minimum age. “But this jump was 25% higher in Austria at 16 than in USA at 21,” Ahammer says. In the past, neural development was thought to stop in our early teens, but a swathe of recent research shows that the adolescent brain undergoes a complex rewiring that does not end until at least the age of 25. Overall, the prognosis for alcoholism can be positive with early intervention, effective treatment, and ongoing support.
