To amend the Controlled Substances Act to fix a technical error in the definitions.

HR 455 corrects a technical numbering error in the Controlled Substances Act's definitions section. It relabels paragraph (58) as (59), moves the definition of "serious drug felony" from paragraph (57) to (58), and adjusts the formatting of these references. This bill makes no policy changes - it only fixes how legal references are ordered in the law. It directly affects legal documents, court filings, and agency enforcement that cite specific definitions under the Act. The change ensures consistency in how the law is referenced but does not alter any substance or impact.
