When adolescents smoke marijuana or drink alcohol, it is common to believe that everyone tries it. However, drug use in young adults can cause severe damage to the brain that can result in deficits later in life because their brains are still being shaped and developed. This issue is supported by three online articles,Parents Ask: How Do Drugs Affect the Brain of a Teenagers written by Sturbridge Staff in 2019, What Alcohol and Drugs Do to a Teens Developing Brainby Stacy Ma on November 11, 2019, and Research Review: What Have We Learned About Adolescent Substance Abuse? by Kevin Gray and Lindsay Squeglia on July 27, 2017. Key points on this issue include why teenagers use drugs, the damages drugs cause on the brain, and misconceptions parents and peers often have about the severity of teenage drug use. The problem is that people often overlook teenage drug use because they think that it is something that all kids go through so it is unpreventable, but these actions can have lasting consequences on teenagers’ brains and impact their future neurological functions, which is a vital factor to consider when dealing with this issue.
