The bill amends South Dakota's controlled substances schedule by adding several new substances to Schedule I, which includes drugs that are considered to have a high potential for abuse and no accepted medical use. Notably, the bill introduces Phenibut and Tianeptine to the list of controlled substances. Additionally, it updates the numbering of the substances in the schedule, resulting in the deletion of certain previously listed substances, including Phenomorphan, Phenoperidine, and Piritramide, among others. The bill also includes a comprehensive list of other substances that are being added to Schedule I, such as 4-chloro-N-[1-[2-(4-nitrophenyl)ethyl]-2-piperidinylidene]-benzenesulfonamide, W-18 and N,N-diethyl-2-(2-(4-isopropoxybenzyl)-5-nitro-1H-benzimidazol-1-yl)ethan-1-amine, also known as isotonitazene. The amendments reflect an effort to address emerging substances that pose risks to public health and safety by ensuring they are regulated under the state's controlled substances laws.
