The main purpose of this legislative text is to classify synthetic 7-hydroxymitragynine as a Schedule I controlled substance under the Controlled Substances Act. The objective is to regulate and restrict the distribution and use of this synthetic compound, which is derived from kratom, a plant known for its psychoactive properties. Key provisions of this legislation include the specific scheduling of synthetic 7-hydroxymitragynine, which means that it will be treated similarly to other highly restricted substances.
