This second Listening Session continues our exploration of Opioid Use Disorder (OUD) in special populations, shifting the lens to the full lifespan. Building upon Part 1's focus on youth and Tribal communities, Part 2 will examine the intergenerational and biological effects of opioid exposure from the womb through later life stages. Panelists will include a speech-language pathologist and lactation consultant working with opioid-exposed infants in neonatal care, a nutritionist exploring how OUD affects metabolism and nourishment, a biomedical engineer sharing technological approaches for assessing long-term developmental impact, and a gerontological expert addressing OUD in older adults.
