Uniform Controlled Substances Act; revise Schedule I.

SB 2117 adds 13 specific substances - including multiple fentanyl variants like acetyl fentanyl, beta-methyl fentanyl, and others - to Mississippi's Schedule I controlled substances list. It also creates a broad category covering fentanyl-related substances with structural modifications (e.g., changes to the phenethyl group or piperidine ring). This classification means these substances are deemed to have no legitimate medical use and a high potential for harm under Mississippi law. The bill directly affects anyone possessing, distributing, or using these substances within Mississippi, subjecting them to stricter state penalties.
