What if the words we use could tip the balance between seeking help and staying silent? In this episode, we explore a fascinating study that compares top-voted Reddit responses with replies generated by large language models (LLMs) to uncover which better reduces stigma around opioid use disorder—and why that distinction matters.

Drawing from Laura’s on-the-ground ER experience and Vasanth’s research on language and moderation, we examine how subtle shifts, like saying “addict” versus “person with OUD, ” can reshape beliefs, impact treatment, and even inform policy. The study zeroes in on three kinds of stigma: skepticism toward medications like Suboxone and methadone, biases against people with OUD, and doubts about the possibility of recovery.

Surprisingly, even with minimal prompting, LLM responses often came across as more supportive, hopeful, and factually accurate. We walk through real examples where personal anecdotes, though well-intended, unintentionally reinforced harmful myths—while AI replies used precise, compassionate language to challenge stigma and foster trust.

But this isn’t a story about AI hype. It’s about how moderation works in online communities, why tone and pronouns matter, and how transparency is key. The takeaway? Language is infrastructure. With thoughtful design and human oversight, AI can help create safer digital spaces, lower barriers to care, and make it easier for people to ask for help, without fear.

If this conversation sparks something for you, follow the show, share it with someone who cares about public health or ethical tech, and leave us a review. Your voice shapes this space: what kind of language do you want to see more of?
