Episode notes
Opioid Exposure Shifted Political Alignment
- Carolina Arteaga finds a causal link from opioid exposure to rising Republican vote share across multiple elections.
- The opioid epidemic reshaped community conditions and political trust, nudging many places rightward over decades.
Purdue's Targeting Creates Research Lever
- Purdue marketed OxyContin to cancer-treatment physicians to expand opioid prescribing beyond terminal care.
- That targeted push created exogenous variation researchers use to link 1996 cancer prevalence to later opioid exposure.
Cumulative Social Harms Drove Voting Change
- The epidemic produced a cascade: more prescriptions, overdoses, disability, poverty, then political shifts.
- Those economic and social harms accumulated and translated into higher Republican vote share by the 2010s.
