28 Warning Signs Your Teen is Drinking Alcohol

Although drinking in moderation can be safe for adults, drinking by anyone under 21 can be a serious issue and should not be ignored, dismissed or minimized.  There are, of course, the immediate risks and harms a young adult may experience from drinking alcohol: they are more likely to have driving accidents, experience death from alcohol poisoning (excessive drinking), have violent behavior, be the victim of violent crime, to have unprotected sex, and to have depression and anxiety.

Equally concerning, a number of reports and studies indicate that drinking by young adults (anyone under 25 years of age) can have serious long-term consequences as well. It is now understood that the human brain is still developing and growing until the mid-20s.  Heavy drinking before the brain has completed its development can cause numerous long-lasting problems.  A recent study by neuroscientist Susan Tapert of the University of California, San Diego compared the brain scans of teens who drink heavily with the scans of teens who don’t.  Tapert’s team found damaged nerve tissue in the brains of the teens who drank. The researchers believe this damage negatively affects attention span in boys, and girls’ ability to comprehend and interpret visual information.

According to a national survey of 43,093 adults, published in Archives of Pediatrics & Adolescent Medicine, 47% of those who begin drinking alcohol before the age of 14 become alcohol dependent at some time in their lives, compared with 9% of those who do not drink until at least age 21.

In a study comparing the brains of youth ages 14 to 21 who did abuse alcohol with those who did not abuse alcohol, researchers found that the hippocampi of drinkers were about 10% smaller than in those who did not drink.  The hippocampus is the area of the brain critical for regulating emotions, for storing and recovering memory, in particular long-term memory and for spatial navigation.  Damage or stunting of the hippocampus can lead to loss of memory and difficulty in establishing new memories. For example with Alzheimer’s disease the hippocampus is one of the first regions of the brain to be affected, leading to the confusion and loss of memory.

Drinking by young adults is a serious issue and can have potentially life-long consequences. So, how can you tell if your teen is drinking or abusing alcohol?  Here are some of the warning signs to look for:

Physical Warning Signs Of Alcohol Use And Abuse

  • Bloodshot eyes
  • Changes in appetite
  • Changes in sleep patterns
  • Shaking, tremors or seizures without a history of epilepsy
  • Poor personal grooming, hygiene and physical appearance
  • Slurred speech
  • Poor coordination
  • Injuries or bruises that your teen can’t remember how they happened
  • Smell of alcohol on breath, body, or clothing
  • Sudden use of breath mints or gum
  • Incoherent or slurred speech
  • Finding alcohol in your teen’s room or with belongings
  • Alcohol missing from house, discovering watered-down bottles of alcohol

Behavior Warning Signs Of Alcohol Use And Abuse

  • Missing school or classes
  • Drop in grades
  • Getting in trouble at school, or with the law
  • Increase in arguments, fights, accidents
  • Loss of interest in previously enjoyed activities, hobbies or sports
  • Missing money or valuables or frequently asking for money
  • Increased isolation, silence, being withdrawn
  • Increase in secretive or suspicious behaviors
  • Refusing to discuss new friends, activities
  • Locking doors
  • Avoiding eye contact
  • Sudden change in friends, favorite hangouts
  • Using eye drops to hide bloodshot eyes
  • Unexplained change in personality and/or attitude
  • Sudden mood changes, irritability, outbursts

Many of the items listed are common in all teenagers.  Nearly all teens will be irritable and have abrupt mood changes due to the hormonal changes they are experiencing.  However, if several of these warning signs occur, be alert for more.  If you do find your teen is drinking or abusing alcohol, talk to them about it.  Explain to them the new findings on what alcohol does to teenage brains and its lasting impact.  See our article on “How to Talk to Your Teen About Alcohol” for more suggestions.

How to Talk to Your Teenager About Drinking To help your young adult/teenager get the fullest from life, it is important to have an honest discussion about alcohol and its effects.  But what do you say and how do you do it? Here is a helpful guide on how to talk to your teenager about drinking.

Long Term Impact of Alcohol and Drug Use on Emerging Adults Emerging Adulthood, the period of life from approximately age 18 to the late 20s, is not only a critical time for psychological and social development, but also for physical brain development. Contrary to a popular assumption that the brain is mature by the age of 18, recent studies have shown that profound brain growth and change still occur during Emerging Adulthood. [Studies]  The heavy use of drugs and alcohol during this time frame can inhibit a person’s brain development and have long term consequences.

Emerging Adults – Time of Stress, Change, and Possibly Addiction The period after high school through the late 20s is now considered a unique developmental phase, Emerging Adulthood.  For Emerging Adults life is typically filled with an unprecedented amount of change and a time for asking many deeply-personal life questions. Robin Marantz Henig discusses some of these changes in her New York Times Magazine article. Emerging Adults frequently change residences (slightly more than 30% move everyyear); change jobs (averaging seven jobs during their 20s); move back with parents (more than 40% move back in with their parents at least once during their 20s); and often spend time living with a romantic partner (66%).  These changes can lead to high levels of stress and anxiety.

5 Things Parents Need to Know About Prescription Drug Abuse Parents of Emerging Adults (ages 18-late 20?s) are important partners in the prevention of drug abuse. In New Hope Recovery Center’s continuing efforts to assist parents, we want to pay special attention to a serious problem impacting Emerging Adults: prescription drug abuse which is the intentional use of medication without a prescription.  Parents may not be unaware of how serious this problem has become, so we want to share 5 must-know facts for parents of Emerging Adults.

Student Drug Abuse Warning Signs Young adults face many temptations and opportunities to use and abuse drugs and alcohol.  As a parent, it is important to allow for appropriate independence and growth for your student or young adult, but also to keep a watchful eye looking for warning signs or symptoms of drug or alcohol use/addiction. Part of growing up involves making mistakes and hopefully learning from them.  These teachable moments allow students and emerging adults to learn how to respond better in the future.  Students and emerging adults may not always be able to quickly identify and correct mistakes or difficulties they face. They also are more susceptible to peer pressure or having their viewpoints shaped by outside influences. For this reason, parents need to be closely aware of what is happening in their young adult’s life.

Fighting Peer Pressure: 3 Ways To Limit Addiction Risk in Young Adults Do you remember growing up and wanting to be liked and included in your peer group?  One of the hardest parts of growing up is feeling excluded from peer groups and while this can be challenging, it is also a normal part of the development of an Emerging Adult.  If it did not come naturally, you might remember changing your attitudes, values or behaviors to belong a certain peer group, which is exactly where your Emerging Adult may be developmentally.
