Genetics, Trauma, and Addiction: A Conversation with Yale Psychiatrist Dr. Peter Na

In this interview, we speak with Dr. Peter Na, an addiction psychiatrist at Yale University Hospital, whose work focuses on how genetics, trauma, stress, and environment shape vulnerability to substance use disorders.

Dr. Na explains what inspired him to pursue addiction psychiatry and breaks down how factors like PTSD, anxiety, and socioeconomic inequities interact with genetic risk. He also shares what brain imaging reveals about opioid use disorder and why understanding these biological changes is key to reducing stigma.

We discuss how research, clinical care, and public policy must work together to improve treatment access and public understanding. Dr. Na highlights treatment approaches that are often misunderstood and offers guidance for students who want to make healthy decisions or support peers struggling with mental health.

Finally, he offers advice for young people, as well as insights into the breakthroughs he hopes to see in addiction research in the years ahead.

If you’re interested in mental health, neuroscience, or addiction prevention, this conversation provides clear, compassionate, and practical insights.
