Controlled substances; provide for automatic scheduling of psilocybin after federal scheduling.

HB 563 requires Mississippi to automatically add a specific pharmaceutical form of psilocybin (approved by the FDA) to the state's controlled substances list once the federal government (DEA) schedules it. This eliminates the need for new state legislation to implement the scheduling and applies only to psilocybin used in FDA-approved medications. The automatic scheduling would remain in effect until the next legislative session passes a new law to update Mississippi's controlled substances schedule.
