Policy changes different rules

Compare classification, criminal penalties, and regulated supply. A legal schedule is not a dose-response ranking.

Policy changes different rules

Controlled Substances Act (CSA) schedule I

High abuse potential; no currently accepted medical use in U.S. treatment; lack of accepted safety under medical supervision.

Criminal penalties remain in this simplified example

No regulated sale authorization follows from possession reform alone

Federal Analogue Act

Under 21 U.S.C. § 813, a qualifying controlled substance analogue intended for human consumption is treated as Schedule I for federal-law purposes. Structural/effect criteria and statutory exclusions matter; chemical resemblance alone is not a complete legal test.

These are independent policy dimensions. Exact rules vary by jurisdiction, conduct, substance, and date. The atlas does not assign current schedules to individual drugs or treat schedules as scientific harm rankings.
