Marijuana may be legal in many places, but that doesn’t mean it’s safe—especially for teens and young adults. In fact, the brains of young people are still developing, and using cannabis during these critical years can cause serious and long-lasting problems.
The truth is, more teens are using marijuana today than ever before, and the marijuana they’re using is far stronger than it was a generation ago. High-potency THC products—like vapes, edibles, and concentrates—are linked to an increase in cannabis use disorder, especially in younger users.
According to the National Institute on Drug Abuse (NIDA), about 1 in 6 teens who use marijuana will become addicted, and for daily users, that number jumps to 25–50%. The Centers for Disease Control and Prevention (CDC) reports that more than one-third of high school seniors have used marijuana in the past year.
As actor and former marijuana user Jim Carrey once said,
“Desperation is a necessary ingredient to learning anything, or creating anything. Period. If you ain’t desperate at some point, you ain’t interesting.”
For many young people, cannabis starts as an escape—but over time, it becomes something they feel desperate to stop.
Let’s take a closer look at how cannabis use disorder affects teens and young adults—and how to get help when it becomes too much to manage alone.
What Is Cannabis Use Disorder?
Cannabis use disorder (CUD) is a medical condition in which a person becomes dependent on marijuana and can’t stop using it, even when it causes problems in their life. It’s similar to other substance use disorders and includes both psychological and physical components.
People with CUD may feel intense cravings for marijuana, spend a lot of time using it, and experience withdrawal symptoms if they try to quit.
While not everyone who uses cannabis becomes addicted, those who start young and use frequently are at the highest risk.
Why Are Teens and Young Adults at Risk?
Teens and young adults are especially vulnerable to cannabis addiction because their brains are still growing. The brain continues to develop into the mid-20s, and using marijuana during this time can interfere with learning, memory, and emotional regulation.
Here’s why youth are more at risk:
- High-potency THC products: Today’s marijuana is stronger than ever, making addiction more likely.
- Mental health issues: Teens with anxiety, depression, or ADHD may use weed to cope—but it often makes things worse.
- Peer pressure and social media: Cannabis use is often glamorized, leading teens to believe it’s risk-free.
- Lack of awareness: Many teens and parents don’t recognize the signs of addiction until it becomes severe.
Signs of Cannabis Addiction in Teens
Recognizing cannabis addiction in teens can be tricky, especially since some signs may look like typical teenage behavior. But if you know what to look for, the warning signs become clearer.
Behavioral Signs:
- Skipping school or falling behind academically
- Losing interest in hobbies or sports
- Changing friend groups or isolating from family
- Sneaking out, lying, or acting secretive
- Stealing money or valuables
Emotional Signs:
- Mood swings or irritability
- Anxiety or panic attacks
- Loss of motivation (“amotivational syndrome”)
- Depression or emotional numbness
- Becoming defensive or angry when asked about marijuana use
Physical Signs:
- Bloodshot eyes or frequent use of eye drops
- Unusual smells on clothes or in the room
- Increased appetite
- Poor hygiene or grooming habits
- Frequent coughing or respiratory issues
If several of these signs appear consistently, your teen may be struggling with teen marijuana addiction.
The Impact of Marijuana Use on the Developing Brain
Research shows that marijuana can change the structure and function of the brain—especially in young people. Regular cannabis use can affect:
- Memory and learning
- Problem-solving skills
- Attention span
- Decision-making abilities
- Impulse control
Teens who use marijuana regularly may struggle with school, have a harder time focusing, and find it more difficult to reach their full potential academically and socially.
Studies also link early marijuana use to a higher risk of developing mental health conditions like schizophrenia, anxiety disorders, and depression.
Cannabis Withdrawal in Teens and Young Adults
One of the most overlooked parts of teen weed addiction is withdrawal. While marijuana withdrawal isn’t usually dangerous, it can be uncomfortable and lead to relapse if not managed properly.
Common withdrawal symptoms include:
- Irritability and anger
- Trouble sleeping
- Loss of appetite
- Anxiety or depression
- Restlessness or shakiness
- Strong cravings for marijuana
- Trouble focusing or thinking clearly
Withdrawal symptoms usually begin within 1–3 days of quitting and can last up to two weeks or more, especially for heavy users.
Consequences of Teen Marijuana Addiction
When cannabis addiction in young adults is left untreated, it can lead to serious consequences, including:
- Academic failure: Lower grades, skipping classes, and decreased motivation
- Legal issues: Underage possession, driving under the influence, or dealing
- Social isolation: Loss of friendships or damaged family relationships
- Mental health problems: Worsening depression, anxiety, or psychosis
- Risk of other drug use: Increased chance of experimenting with more dangerous substances
Many of these issues don’t go away with time—they grow worse, making early intervention essential.
Getting Help for Teen Marijuana Addiction
The good news is this: help for teen marijuana addiction is available, and recovery is absolutely possible. Early treatment increases the chance of success and reduces long-term harm.
Here’s where to start:
1. Talk to a Doctor or Mental Health Professional
A professional can assess the level of use and recommend the best treatment options. They can also check for co-occurring conditions like depression or anxiety.
2. Outpatient Therapy
Cognitive Behavioral Therapy (CBT), Motivational Enhancement Therapy (MET), and family-based interventions are all effective treatments for teens.
3. Family Counseling
Getting the whole family involved can rebuild trust, improve communication, and help parents learn how to support their child in recovery.
4. Support Groups
Peer groups like Marijuana Anonymous (MA), SMART Recovery, or Alateen offer a safe space to share struggles and get support from others going through the same thing.
5. School Resources
Many schools offer on-campus counselors, support programs, or referrals to local treatment providers.
Preventing Cannabis Use Disorder in Youth
Prevention is just as important as treatment. Here are steps parents, schools, and communities can take:
- Talk early and often: Open, honest conversations help reduce stigma and build trust.
- Set clear expectations: Let your teen know the risks and your values around substance use.
- Know their friends: Peer pressure is powerful—knowing who your child spends time with can make a difference.
- Monitor social media: Cannabis is often glamorized online. Help teens develop media literacy.
- Offer support, not punishment: Teens need guidance, not shame, when they make mistakes.
Final Thoughts: You’re Not Alone
Cannabis use disorder in teens and young adults is more common than people realize—but it’s also treatable.
If you’re a teen struggling to quit, or a parent who’s worried, take a deep breath. You’re not alone. Thousands of families are facing this challenge, and there is hope.
Recovery isn’t about being perfect—it’s about taking the next step. Whether it’s talking to a counselor, joining a support group, or simply admitting there’s a problem—that step could change everything.
As former NFL player and addiction survivor Chris Herren said:
“The comeback is always stronger than the setback.”
And your comeback can start today.
