Residual amount defined in relation to controlled substances.

HF 2091 defines "residual amount" for controlled substances as any quantity that is not usable, even if it could still have a pharmacological effect. This definition will be used in Minnesota courts and law enforcement for drug-related cases, such as possession charges involving small quantities of regulated drugs. The bill amends Minnesota Statutes 2024, section 152.01, to include this specific definition, effective August 1, 2025, with retroactive application to all cases occurring before that date. This change provides a clear, consistent standard for legal proceedings involving controlled substances.
