Residual amount definition establishment in relation to controlled substances

This bill defines "residual amount" for controlled substances under Minnesota law. It specifies that a "residual amount" means any quantity of a controlled substance that is not usable, regardless of whether it could still cause a physical or chemical effect. This definition applies to drug-related crimes committed on or after August 1, 2025, and retroactively covers crimes committed before that date. The change clarifies a legal term used in sentencing and prosecution for controlled substance offenses.
