Oxycontin is still legal, as is methamphetamine (Desoxyn) and cocaine (Numbrino). They can all be legally prescribed by a physician, although as DEA scheduled controlled substances they are subject to tight restrictions.

The issue with Oxycontin (and related opioid painkillers) wasn't the legal status. It was over prescription triggered by a range of unethical actions by pharmaceutical companies (mainly Purdue Pharma) plus some doctors who took advantage of the situation.
