What Is Marijuana & THC?

Marijuana contains THC (tetrahydrocannabinol), the chemical responsible for its psychoactive effects. THC affects the brain, especially areas related to memory, decision-making, mood, and attention.

Because the adolescent brain is still developing, THC exposure can have stronger and longer-lasting effects on teens than on adults.

Why Marijuana & THC Can Be Risky for Young People

THC can interfere with brain development and may increase the risk of anxiety, depression, and problems with focus and learning. Today’s marijuana products often contain much higher levels of THC than in the past.

Edibles and other products may look harmless but can deliver unpredictable doses.

How Kids Are Being Exposed to Marijuana & THC

THC is available in many forms, including:

• Vapes and cartridges
• Gummies, chocolates, and baked goods
• Drinks or candy that look like everyday snacks
• Concentrates (“dabs,” oils, waxes)

Some products are intentionally packaged to resemble familiar brands, making it harder to recognize risk.

Signs of Marijuana or THC Use

Signs may include:

Physical signs

• Red or glassy eyes
• Increased appetite
• Fatigue or lack of motivation
• Changes in coordination

Behavioral signs

• Mood swings or irritability
• Declining school performance
• Loss of interest in activities
• Increased secrecy or changes in friend groups

One sign alone doesn’t indicate use. Patterns and changes over time matter most.

How to Start the Conversation

Effective conversations focus on curiosity, not confrontation.

Helpful principles:

• Ask open-ended questions
• Listen without judgment
• Avoid exaggeration or scare tactics
• Keep the focus on health and safety

What These Conversations Can Sound Like

These are examples — not scripts. Use language that feels natural to you.

Example 1: Opening the Topic

Parent:
“Marijuana seems to come up a lot more than when I was growing up. What do kids your age think about it?”

Example 2: Talking About Edibles

Parent:
“I didn’t realize some THC products look like regular candy or snacks. Have you ever seen that?”

Why this works: Raises awareness without accusation.

Example 3: If a Child Minimizes Risk

Child:
“It’s not a big deal — it’s legal.”

Parent:
“Some things are legal for adults but still risky for growing brains. That’s why I wanted to talk.”

Example 4: Keeping the Door Open

Parent:
“If you ever feel pressured or unsure, you can always come to me. We’ll figure it out together.”
