Abstract

Physicians’ fear of criminal prosecution for prescribing opioid analgesics is a major reason why many chronic pain patients are having an increasingly difficult time obtaining medically appropriate pain relief. In Ruan v. United States, 142 S. Ct. 2370 (2022), the Supreme Court unanimously vacated two federal convictions under the Controlled Substances Act. The Court held that the government must prove that the defendant knowingly or intentionally acted in an unauthorized manner.
