In the Massachusetts episode of Parts Unknown, Bourdain talks to a general physician who explains how patients who were administered OxyContin for routine procedures & injuries quickly developed a habit for the drug and when they couldn't find it post-treatment moved to illegal variants like Heroin and now Fentanyl.[1][2]

Bourdain travels to Franklin County to explore the heroin epidemic that’s spreading throughout this and other New England towns.[1]

Dr. Ruth Potee of Greenfield, Massachusetts talks about how they were taught in their residency that their ER / Hospital performance was tied to their pain scores and the generous administration of pain medication to patients.[1][2]
