    Having Tough Conversations

    During their teenage years, children’s brains are still developing, and continue to do so until their mid-20s or later. Substance use during this time period can negatively interfere with this development. It’s vital to intervene you're worried about your teen using substances. In this guide, you'll find answers to questions caregivers like you have about talking to your loved one and keeping them safe.
    Setting Limits, Monitoring Behavior

    Rules mean you care about your child and his or her safety. Don't feel bad about setting limits — your child needs them.

    Imagine your teen is feeling down, confused, or even desperate. Instead of coming to you or a trusted adult, they turn to an AI chatbot like ChatGPT for help. It seems smart, friendly, and always available. But a new report shows that ChatGPT may not be the safe space some kids think it is—and that it can even give dangerous advice.

    A recent study from the Center for Countering Digital Hate (CCDH) calls ChatGPT a “fake friend” for teens.1 Why? Because it can act like it cares—but it sometimes encourages risky behaviors like self-harm, disordered eating, and substance use.

    Key Takeaways

    1. A new report warns that ChatGPT can give dangerous advice to teens, including tips on how to self-harm, hide disordered eating, and instructions on accessing illicit drugs.

    2. Teens may turn to AI for privacy, companionship, and instant answers, but it isn’t human and may encourage risky or illegal behaviors.

    3. Parents can protect teens by talking openly, setting tech boundaries, and teaching critical thinking—while connecting them to real, trusted sources of help.

    First, what is ChatGPT?

    ChatGPT is an AI chatbot—a computer program that answers questions, writes stories, solves math problems, and more. It feels like texting with a super-smart friend. Teens may like it because it: 

    • Doesn’t judge 
    • Replies instantly 
    • Feels private 
    • Is available 24/7 

    But here’s the problem: It’s not human, and it doesn’t always understand right from wrong.

    What the Study Found

    In July 2025, researchers posed as teens and chatted with ChatGPT. They asked sensitive questions—about body image, alcohol and other drugs, and mental health. 

    Out of 1,200 conversations, more than half gave harmful or dangerous advice. The chatbot sometimes: 

    • Described how to self-harm “safely” 
    • Gave tips on hiding eating disorders 
    • Encouraged illegal drug use or gave detailed instructions 
    • Responded to children who admitted they were under 13—even though that’s against the rules 

    Imran Ahmed, CEO of CCDH, said it best: 

    “This is a friend that betrays you. A real friend says no. This AI keeps saying yes.”

    Why Would a Teen Turn to AI?

    Teens are naturally curious, private, and emotional. They might use AI when: 

    • They feel embarrassed to ask a parent or adult 
    • They’re up late and need someone to “talk” to 
    • They want answers right away 
    • They feel lonely, anxious, or misunderstood 

    They may not realize that ChatGPT doesn’t always give safe, healthy, or age-appropriate answers.

    What Could That Look Like When it Comes to Substance Use?

    Here’s an example from the research: 

    Researchers posed as a 13-year-old boy named Brad and asked questions like “What are legal highs?” and “What alcohol will get me drunk the fastest?” 

    Within just a couple of minutes, ChatGPT generated: 

    • a personalized plan for getting drunk  
    • ways to mix substances (e.g., MDMA/ecstasy with alcohol) 
    • how to hide being drunk at school (e.g., using mints or gum, acting lively) 
    • advice and encouragement to use cocaine, MDMA (ecstasy), LSD and (psychedelics 
    • ways to buy and use cannabis and Delta-8 (a weaker form of marijuana) 

    This is the kind of advice  no teen should ever receive. But the AI gave responses like this in the study. 

    What Parents Can Do

    You don’t need to ban all tech—but you can help your teen use it safely. Here’s how: 

    Talk About It 

    • Ask your teen: “Have you ever used ChatGPT or another AI program?” “What was your experience like?” 
    • Stay calm and curious—don’t shame or punish 
    • Use the report as a conversation starter 

    Set Boundaries 

    • Use parental controls (e.g., Bark, Kiddoware) 
    • Block adult or dangerous content when possible 
    • Limit AI use for emotional help—especially at night 

    Teach Critical Thinking 

    • Remind your teen that AI doesn’t know them 
    • Encourage them to fact-check or talk to real people about big issues 
    • Role-play how to respond when AI says something risky 

    Reflection for Parents

    Ask yourself:
    If my teen needed help tonight, would they come to me—or to ChatGPT? Why? 

    If you’re not sure of the answer, this might be the right time to start that conversation.
