Intergenerational Effects of Opioid Exposure and Child Health, Human Capital, and Well-being Using Linked Microdata

The opioid crisis in the United States and Canada has reached unprecedented levels. One understudied dimension is its impact on the next generation. We use linked administrative data from the Canadian province of British Columbia (where opioid death rates exceed the U.S. national average) that links birth records since 2000 to health, education, well-being, and mortality for both the mother and the child. We have three main findings. First, the number of newborns exposed to opioids in utero (obtained from data linking newborn and mother medical records) is many times larger than commonly reported statistics which rely on diagnoses of neonatal abstinence syndrome. Second, exposure to in-utero opioids is associated with large and persistent adverse child health, human capital, and well-being outcomes; these associations are above and beyond what is predicted by the mother’s socioeconomic status and the newborn’s health. Finally, two different quasi-experiments provide suggestive evidence that causal estimates are qualitatively similar but noisy.

He is affiliated with the U.S. Veterans Affairs Office of Mental Health and Suicide Prevention. Previously, he was on the faculty at McMaster University and a postdoctoral scholar at Princeton University. He received his Ph.D. in economics from Stanford University and his BSc from the University of British Columbia.

Zhang’s research spans health economics and public finance. He studies the impacts of physician behavior, health policies, and safety net programs on well-being. He is particularly interested in the areas of mental health and substance use.
