What Parents and Educators Need to Know About Modern Cannabis
Key Takeaways
- Today’s cannabis products are much stronger than those available a generation ago.²
- THC levels in cannabis flower have increased significantly over the past few decades, and some concentrates contain more than 80–90% THC.²
- The teen brain is still developing into the mid-20s, making young people more vulnerable to cannabis-related risks.¹ ³
- About 15% of U.S. high school students report current cannabis use.¹
- Honest conversations and trusted relationships can help teens make healthier decisions.⁴
Many parents remember cannabis as something that looked and felt very different from what young people may encounter today.
Over the last few decades, cannabis products have changed in a big way. They are often much stronger, come in more forms, and are easier to find than they once were.¹ ² At the same time, legalization in many states has created confusion for some teens.
A common question is:
“If it’s legal, doesn’t that mean it’s safe?”
It’s a fair question—and one many parents and educators are trying to answer.
The good news is that you don’t need to be an expert to have these conversations. Understanding a few key facts can help you talk with young people in a way that is honest, informed, and grounded in trust.
Cannabis Is Much Stronger Than It Used to Be
One of the biggest changes is potency.
THC, the chemical responsible for the “high” associated with cannabis, is found in much higher concentrations than it was a generation ago.² According to the National Institute on Drug Abuse (NIDA), average THC levels in cannabis flower increased from about 4% in 1995 to more than 15% by 2021.²
Some products contain even higher amounts.
Concentrates such as:
- Wax
- Shatter
- Dabs
- THC oils
- Vape concentrates
can contain THC levels ranging from 60% to more than 90%.²
For many adults, that’s a surprising difference.
The cannabis products available today can produce stronger effects than the products many parents remember from their own teenage years. Higher-potency products have also been linked to an increased risk of severe intoxication, cannabis use disorder, and cannabis-related emergency room visits among some users.² ⁵
How Many Teens Use Cannabis?
While most teens are not using cannabis regularly, it remains one of the most commonly used substances among young people.¹
According to the CDC:
- About 15% of high school students reported using cannabis in the past 30 days.¹
- Nearly 30% reported trying cannabis at least once in their lifetime.¹
These numbers matter because many teens are hearing about cannabis long before adults bring up the topic.
They may see it on social media, hear about it from friends, or come across it in music, entertainment, and advertising.
That’s why early, honest conversations can make a difference.
Why the Teen Brain Matters
One reason health experts encourage teens to avoid or delay cannabis use is that the brain is still developing well into the mid-20s.³
The areas responsible for decision-making, planning, judgment, and self-control are among the last parts of the brain to fully mature.³
Because these skills are still developing, adolescence is an important time for brain health.
According to NIDA, regular cannabis use during the teen years may affect attention, memory, learning, and information processing.²
Some studies have also linked frequent adolescent cannabis use with:
- Lower grades
- Increased school absences
- Reduced educational achievement
- Greater risk of developing cannabis use disorder later in life² ⁵
This doesn’t mean every teen who tries cannabis will experience these outcomes. But it does help explain why health experts recommend waiting until adulthood.¹ ²
Cannabis Doesn’t Always Look Like Cannabis
When many adults think about cannabis, they picture dried plant material that is smoked. That’s no longer the whole picture.
Today’s products include:
- Vape cartridges
- Disposable vape pens
- Gummies
- Chocolates
- Drinks
- Oils
- Capsules
- Concentrates²
Some products look very similar to everyday consumer items.
That can make it harder for parents to recognize them and easier for teens to underestimate the risks.
Cannabis vaping has also become more common among adolescents. According to the 2023 Monitoring the Future survey, nearly 1 in 5 high school seniors (19.6%) reported vaping cannabis in the previous year.⁷
Researchers are particularly concerned because many vape products contain highly concentrated THC.²
What Parents Should Know About Edibles
Edibles work differently than smoked or vaped cannabis.
When cannabis is inhaled, the effects are often felt within minutes. Edibles can take longer, sometimes up to two hours or more.²
Because of that delay, some people take additional doses before the first one has taken effect. The result can be a much stronger experience than they expected. Edibles also raise another concern for families.
Many products resemble:
- Candy
- Gummies
- Cookies
- Brownies
- Chocolate bars
A study published in 2023 found that cannabis edible poisonings among children younger than six increased by more than 1,300% between 2017 and 2021, with more than 7,000 reported cases.⁵
If cannabis products are present in a home, health experts recommend storing them securely and out of reach of children.⁵
Cannabis and Driving Don’t Mix
Many parents talk to their teens about drinking and driving. Cannabis deserves the same conversation.
According to the CDC, cannabis can affect reaction time, attention, coordination, and judgment.¹
A large review of studies found that drivers who recently used cannabis were about 25% more likely to be involved in a motor vehicle crash.¹
For teens, who already have less driving experience, that added risk is especially important to understand.
Understanding Cannabis Use Disorder
Many people are surprised to learn that cannabis can become addictive.
According to NIDA, about 3 in 10 people who use cannabis may develop cannabis use disorder.²
The risk is even higher for people who start using before age 18.²
Signs of cannabis use disorder can include:
- Strong cravings
- Difficulty cutting back
- Continued use despite problems
- Trouble meeting responsibilities at school, work, or home²
Most teens who experiment with cannabis will not develop a substance use disorder. Still, understanding the possibility helps young people make more informed choices.
Mental Health and Cannabis
The link between cannabis and mental health is a topic researchers continue to study closely.⁵ ⁶
The National Academies of Sciences found that regular cannabis use is associated with an increased risk of schizophrenia and other psychotic disorders, especially among frequent users.⁵
Other studies have found links between heavy adolescent cannabis use and higher rates of:
- Anxiety symptoms
- Depression symptoms
- Suicidal thoughts
- Psychotic experiences in vulnerable individuals⁵ ⁶
It’s important to remember that cannabis does not affect everyone the same way.
Factors such as family history, mental health history, frequency of use, and product potency can all play a role.⁵
Legal Does Not Mean Safe for Teens
One question many young people ask is:
“If cannabis is legal, how can it be harmful?”
It’s a reasonable question. The answer is, legality and safety are not the same thing.
Alcohol is legal for adults but not for minors. Prescription medications can be beneficial when used appropriately but harmful when misused.
Cannabis laws that allow adult use recognize that mature adults and developing adolescents face different levels of risk.¹
Helping teens understand this distinction can encourage more thoughtful decision-making.
Warning Signs Parents Should Know
Many normal adolescent behaviors can look similar to signs of substance use.
However, parents may want to pay attention to patterns such as:
- Sudden declines in grades
- Increased secrecy
- Loss of interest in favorite activities
- Changes in friend groups
- Mood changes
- Reduced motivation
- Possession of vaping devices or cannabis products²
No single behavior proves cannabis use. If concerns arise, experts recommend approaching the situation calmly and with curiosity rather than immediately jumping to conclusions.⁴
What to Do If You’re Concerned
If you suspect a teen may be experimenting with cannabis, maintaining communication is one of the most important first steps.⁴
Consider:
- Asking open-ended questions
- Listening before reacting
- Avoiding assumptions
- Discussing health concerns respectfully
- Reinforcing expectations
- Seeking professional guidance if concerns persist⁴
Research consistently shows that young people are more likely to engage in meaningful conversations when they feel heard rather than judged. Studies also suggest that prevention efforts are most effective when teens receive balanced, accurate information from trusted adults.⁴
When adults acknowledge both what is known and what is still being studied, they build credibility.
The Conversation Starts With Connection
Parents and educators do not need to have all the answers.
What matters most is creating opportunities for ongoing dialogue.⁴
- Ask questions
- Listen carefully
- Share age-appropriate facts
- Stay curious
- Keep the conversation going
The most effective prevention rarely comes from one big talk. It comes from many small conversations over time.
Helping Teens Protect What Matters Most
At Natural High, we believe prevention is about more than avoiding negative outcomes.
It’s about helping young people discover activities, relationships, goals, and passions that give them a sense of purpose.⁴
Whether it’s sports, music, art, leadership, academics, volunteering, or another meaningful pursuit, young people are more likely to make healthy choices when they have something positive they’re excited to protect.⁴
When teens see a future worth investing in, healthy decisions often become easier to make.
Today, cannabis is stronger, more accessible, and more visible than ever before. That makes trusted adults more important than ever.
You don’t need a perfect script. You simply need to stay connected, informed, and keep the conversation going.
