Why is quitting so difficult, whether it's alcohol, nicotine, gambling, social media, or another addictive behavior? In this episode of Health Matters, Dr. Jonathan Avery, an addiction psychiatrist at NewYork-Presbyterian and Weill Cornell Medicine, explains what addiction really is, how it affects the brain, and why recovery is about far more than willpower.Dr. Avery discusses the complex mix of biology, mental health, environment, and life experiences that can contribute to addiction. He explains how substances and behaviors hijack the brain's reward pathways, why withdrawal can make quitting especially challenging, and how treatments ranging from therapy and medication to community support can help people recover.The conversation also explores the stigma surrounding addiction, the importance of connection and compassion, and why many people go on to build meaningful, fulfilling lives in recovery.
