A recent study out of Harvard that looks at rates of opioid overprescription by U.S. congressional district finds that while Texas overall has lower overprescription rates than the national average, Districts 4 and 1 greatly exceed that average.
According to the study, the rate of opioid overprescription nationally in 2016 was about 65 percent, meaning that two-thirds of Americans prescribed opioid drugs were prescribed more than they needed. In Texas, that rate was 58 percent overall.
