The Importance of Substance Use Prevention from an Early Age
Substance use prevention is one of the most effective investments we can make in the health and future success of children and adolescents. Research consistently shows that substance use often begins during the teenage years, making early prevention efforts critical.
“Our youth deserve a fair shot at living happy, healthy, successful lives and early use of substances can quickly rob them of opportunities to do so,” says Hannah Davis, tCADC, Recovery Outreach Specialist, Mercy’s Sedlacek Treatment Center.
Childhood and adolescence are critical periods of brain development. Areas of the brain responsible for decision-making, impulse control, learning, and emotional regulation continue developing well into young adulthood. The National Institute on Drug Abuse (NIDA) reports that early exposure to alcohol, nicotine, cannabis, and other substances can interfere with normal brain development and increase the likelihood of developing a substance use disorder later in life.
The need for prevention is clear. According to the Centers for Disease Control and Prevention (CDC), 15% of high school students report using illicit drugs, while 14% report misusing prescription opioids. These behaviors are associated with increased risks of overdose, mental health concerns, violence, academic difficulties, and long-term health consequences. Additionally, national survey data show that substance use increases with age during adolescence, with at least 25% of twelfth-grade students reporting the use of an illicit substance within the previous year.
Why Adolescence Is a Critical Window for Prevention
Adolescence represents one of the most important opportunities for substance use prevention. During the teenage years, young people experience significant physical, emotional, and social changes while also gaining greater independence and exposure to peer influences. At the same time, the brain's reward system develops more quickly than the areas responsible for judgment and impulse control, making adolescents more likely to engage in risk-taking behaviors. This combination of increased curiosity, social pressure, and ongoing brain development can make teens particularly vulnerable to experimenting with substances.
Research shows that delaying substance use can have a profound impact on long-term health outcomes. Individuals who begin using substances at an earlier age are significantly more likely to develop substance use disorders than those who delay use until adulthood. In addition, a large national study that followed thousands of children through adolescence found that use of cannabis demonstrated slower growth in memory, attention, language, and processing speed compared to their peers.
That’s why Mercy’s Sedlacek Treatment Center is offering a free community-based prevention program for ages 11 – 14 this summer.
“I worked with youth in Cedar Rapids prior to coming to Mercy. I saw firsthand the impact substance use has on our young people and the way it disconnects them from their community in so many ways,” says Hannah.
Prevention during adolescence is most effective when it focuses on building strengths rather than simply warning about risks. Evidence-based prevention programs teach young people practical skills such as decision-making, emotional regulation, communication, stress management, and resistance to peer pressure. These skills help adolescents navigate challenges and make the right choices when faced with opportunities to use substances.
Parents, schools, healthcare providers, and communities all play a vital role in prevention. Adolescents who have strong family connections, regular communication with trusted adults, clear expectations regarding substance use, and involvement in extracurricular activities are less likely to engage in risky behaviors. Participation in sports, clubs, volunteer activities, and other positive social opportunities can strengthen a young person's sense of belonging and reduce the likelihood of substance use.
Importantly, prevention is not simply about avoiding drugs and alcohol—it is about helping young people develop the knowledge, confidence, resilience, and support systems needed to thrive. By investing in prevention early and continuing those efforts throughout adolescence, families and communities can reduce substance use, improve health outcomes, strengthen academic success, and help young people reach their full potential.
“This program helps kids learn valuable skills in a way that resonates with them. They are able to learn while doing interactive lessons. The program is tailored specifically to this age group and presents important topics in a way that helps kids process the information,” says Jade Jackson, LBSW, tCADC, Case Manager, Mercy’s Sedlacek Treatment Center.
