> "Once prescription opioids became an evident crisis, the government took steps to restrict the supply, raising the price. Yet opioid consumption and overdoses went up. Explain that Mr. Chicago economist!"

First, comparing whites and blacks is misleading, you'd want to compare wealthy vs. poor consumers of the drug. Second, lumping 'opiods' together makes little sense when fentanyl is so different in activity-per-gram, and cost-of-production relative to oxy, heroin, and morphine. Third, overdoses are often related to opiate addicts using drugs of varying purity, which is what is found on illegal markets (plus other confounders like suicide attempts, recovering addicts who've lost tolerance falling off the wagon, etc.).

Just more evidence that Chicago School Economics is just artful propaganda financed by oligarchs to promote further accumulation of wealth in the hands of the few.
