Severe flooding raises deadly overdose risk in rural Appalachia, study finds – and the harm lasts for years
Disasters weaken support systems that take years to rebuild, at the same time people caught in them are under extraordinary financial and psychological stress.
Severe flooding in rural Appalachia has been linked to a heightened risk of overdose deaths, with the impact lasting for years after the disaster, according to a recent study. McKayla, a resident of southeastern Kentucky, experienced firsthand the devastating effects of a flood that struck her home in July 2022. With no time to evacuate, she and her children were submerged by rising water, eventually being rescued by a National Guard boat.
The trauma and loss of her home left McKayla vulnerable, causing her to relapse into drug use. This study, led by Mengjun Ge, Zhen Lei, and Arden S. Barnes, examined the long-term effects of flooding on substance use-related harms in rural Appalachia, finding a 26% increase in opioid overdose deaths in flood-damaged areas over the following decade compared to unaffected counties.
The disruption of treatment services, loss of jobs and homes, and the resulting stress and trauma all contributed to the elevated overdose risk, particularly among individuals with limited education and in economically distressed rural counties.
