Fake Friend How ChatGPT betrays vulnerable teens by encouraging dangerous behavior

Last month, CCDH researchers carried out a large-scale safety test on ChatGPT, one of the world’s most popular AI chatbots. Our findings were alarming: within minutes of simple interactions, the system produced instructions related to self-harm, suicide planning, disordered eating, and substance abuse – sometimes even composing goodbye letters for children contemplating ending their lives.

Out of 1,200 responses to 60 harmful prompts, 53% contained harmful content. Simple phrases like “this is for a presentation” were enough to bypass safeguards. Worse, the chatbot often encouraged ongoing engagement by offering personalized follow-ups, such as customized diet plans or party schedules involving dangerous drug combinations. 

For parents, this isn’t about terms like “guardrails” or “content filters”. It’s about whether your child, while privately seeking advice late at night on topics they may feel too sensitive to share with you, is being given guidance that could put their life at risk. 

For policymakers, the issue isn’t just “AI gone wrong” – it’s that widely used safety systems, praised by tech companies, fail at scale. These failures aren’t random bugs; they are deliberately designed features of systems built to generate human-like responses. The systems are intended to be flattering, and worse, sycophantic, to induce an emotional connection, even exploiting human vulnerability – a dangerous combination without proper constraints. 

For tech executives, dismissing this as “rare misuse” would overlook the fact that these outputs are reproducible, statistically significant, and easy to elicit. When 53% of harmful prompts produce dangerous outputs, even with warnings, we’re beyond isolated cases. 

Until meaningful steps are taken, parents can take an interest in their kids’ use of AI, review chat histories together, and use parental controls where available. They can also talk about why seeking advice from AI can be risky, pointing to trusted alternatives like mental health hotlines, peer support, etc. 

AI systems are powerful tools. But when more than half of harmful prompts on ChatGPT result in dangerous, sometimes life-threatening content, no number of corporate reassurances can replace vigilance, transparency, and real-world safeguards. 

If we can’t trust these tools to avoid giving kids suicide plans and drug-mixing recipes, we need to stop pretending that current safeguards are effective.

Study at a glance
  • Question: Does ChatGPT generate harmful responses when prompted about sensitive issues like self-harm and substance abuse?
  • Setting and data: ChatGPT; 1,200 responses to 60 harmful prompts.
  • Method: Safety testing of an AI chatbot using harmful prompts.
Why it matters

Vulnerable teens privately seeking advice on sensitive topics risk receiving guidance from AI chatbots that puts their lives at risk. Systems built to induce emotional connections can exploit human vulnerability without proper constraints.

Key findings
  • In a safety test of ChatGPT, 53% of 1,200 responses to harmful prompts contained dangerous content on self-harm, suicide, disordered eating, and substance abuse.
  • Simple phrases like "this is for a presentation" were enough to bypass the chatbot's safety safeguards.
  • The chatbot often encouraged continued engagement through personalized follow-ups, such as tailored diet plans or schedules involving dangerous drug combinations.
