Uniform Controlled Dangerous Substances Act; modifying classification of certain substances. Effective date.
SB 1257 amends Oklahoma's Uniform Controlled Dangerous Substances Act to update the classification of specific substances. It adds certain substances to Schedule I (Section 2-204) and adds/removes substances from Schedule III (Section 2-208). These changes modify which substances are legally controlled under state law, affecting law enforcement, medical practitioners, and entities handling controlled substances. The bill also updates related definitions in Section 2-101, including clarifications on "acute pain" and "drug paraphernalia." This procedural update adjusts the legal framework for controlled substances without creating new programs or penalties.
