Everything’s turning green for St. Patrick’s Day. Decorations. Shirts. Even bagels. It stands out as a vivid seasonal cue. It can also be a reminder for parents and caregivers to think about which “green lights” they want to set for the teens in their lives, and which ones they do not. Because let’s face it, the holiday is associated with alcohol. That makes St. Patrick’s season a useful moment to pause and talk about expectations around alcohol and other drugs and their impact on teens.
Prevention is not one big talk. It’s a series of small, age-appropriate conversations and everyday habits that help young people build skills, feel connected, and understand the effects of substances.
In a season full of green, it can be helpful to ask a simple question: which “green lights” are we giving our kids? The answers start with understanding why prevention matters and how families can steadily build the habits and supports that help teen wellness.
Why ongoing prevention matters.
Prevention is as important as wearing a seatbelt or applying sunscreen. It works best before you need it. It protects against harm before trouble even starts.
Preventing underage drinking and drug use is not only about avoiding immediate risks. Research shows that early substance use can affect brain development, mental health, learning, and the likelihood of addiction later in life.
1. The teen brain is still developing.
The legal drinking age of 21 exists because the brain continues developing into the mid-20s, particularly in areas controlling judgment, impulse control, and decision-making. Alcohol can interfere with this development and increase the risk of long-term problems. (Source: National Institute on Alcohol Abuse and Alcoholism).
2. Mental health and substance use are connected.
Research finds a strong relationship between substance use and mental health during adolescence. Teens who begin using alcohol or drugs early are more likely to report symptoms of depression and anxiety later, and mental health challenges can also increase the likelihood that a young person will begin using substances. Longitudinal studies show that alcohol-related problems and depressive symptoms often reinforce one another over time during adolescence and young adulthood. Substances can also interfere with brain systems that regulate mood, stress, and decision-making at a stage when emotional regulation is still developing. These overlapping risks are one reason prevention efforts often focus on strengthening coping skills, emotional support, and healthy ways to manage stress. (Source: National Library of Medicine)
3. Protecting focus, stamina, and performance.
Substance use can undermine the skills students rely on to succeed in school and athletics. Alcohol and other drugs can impair memory, attention, sleep, coordination, and reaction time, which research links to lower academic performance and reduced athletic endurance and recovery (Source: National Library of Medicine).
4. Delaying use lowers long-term addiction risks.
Research suggests that early alcohol use in adolescence significantly increases the chances of alcohol abuse and dependence later in life. Delaying the first drink reduces those risks (Source: National Library of Medicine).
The goal of prevention is not control. It’s to equip young people with the tools, relationships, and knowledge they need to make healthy decisions.
Green lights: what to grow over time.
What does prevention actually look like in everyday life? Many of the most powerful strategies are simple habits families can build over time.
Building skills, not just rules.
Kids and teens need to practice skills they can use in real situations. Chat with them: what should refusal skills look like for them? How might they say “no” in their own words? What other activities could they suggest? How might they support a friend? Develop an escape plan, such as a code word or text, when they want you to pick them up, no questions asked.
Research on social-emotional learning and life-skills programs shows that strengthening skills like communication, emotional regulation, and problem-solving can reduce later substance use. Practicing short, realistic scenarios together makes it more likely that teens will remember what to do if they feel caught off guard.
Strengthen protective factors at home.
Simple routines help build connection. Share meals when possible. Check in about their day. Show up for games or performances. Chat while driving. Take a walk together. Notice their efforts. All of these contribute to a sense of belonging.
Research has found that strong parental support and monitoring are linked with lower levels of adolescent alcohol and substance use. When young people feel supported, listened to, and understood, they are more likely to talk about stress or peer pressure before it turns into risky behavior.
Support social-emotional learning.
Talk about feelings, coping strategies, and problem-solving in everyday life, not only when something goes wrong. Skills such as emotional awareness, self-control, and decision-making function as protective factors against substance use.
Teen brains are still developing in areas related to judgment and impulse control, which makes supportive guidance and practice especially important. These skills can be strengthened at home, in school, and through activities like sports, arts, and clubs, so educators and coaches, we’re talking to you, too.
Share positive norms and real numbers.
Many teens overestimate how many of their peers are drinking or using substances. In reality, most are not. National data from the Monitoring the Future study, led by researchers at the University of Michigan and supported by NIDA, shows that adolescent drug use remains at historic lows. Most teens report no recent use of alcohol, cannabis, or nicotine. Teens may think that the majority of their peers drink or use drugs, but this is false. The majority do not. Dispel misconceptions. Sharing these facts helps counter the belief that “everyone is doing it” and makes it easier for teens to feel confident choosing not to use.
Offer age-appropriate education, again and again.
In early years, prevention may mean simple messages about protecting their bodies and not taking anything unless a trusted adult provides it. As children grow older, conversations can include how alcohol and other drugs affect the developing brain, decision-making, and safety.
Short, ongoing conversations tend to be far more effective than a single lecture. Young people consistently say that they value open discussions where they can ask questions and feel respected.
Stay interested in their world.
Ask, in a caring manner, about their friends, interests, games, and online spaces. Research on parental monitoring consistently shows that when parents know where teens are, who they are with, and what they are doing, adolescents are significantly less likely to engage in alcohol and other drug use.
And as a bonus, curiosity shows that your relationship with them is about understanding who they’re becoming, not simply enforcing rules.
Using the green of the season as a reminder.
This month, the green all around us can serve as a reminder to check in.
What skills are we helping kids practice?
Which protective factors are being strengthened at home?
What messages are they hearing about what most teens are actually doing?
Facts, data, stories, and scenarios can help reinforce your messages. Even short conversations help reinforce expectations and remind teens that they have support if they ever feel pressure.
In a season filled with green, your steady guidance helps your child know where it’s wiser to pause, and where it’s truly safe to “go.”
