Amends GS 90-94 by adding the following. Excludes any prescription drug approved by the federal Food and Drug Administration under Section 505 of the federal Food, Drug, and Cosmetic Act that is designated, rescheduled, or deleted as a controlled substance under federal law from Schedule VI and allows it to be prescribed, distributed, dispensed, and used in accordance with federal law upon the issuance of a notice, final rule, or interim final rule by the United States Drug Enforcement Administration that designates, reschedules, or deletes such prescription drug as a controlled substance under federal law. Makes an exception for when the Commission for Mental Health, Developmental Disabilities, and Substance Abuse Services objects to such action; if no objection is made, the prescription drug is deemed to be designated, rescheduled, or deleted as a controlled substance in accordance with federal law and in compliance with GS Chapter 90.
