The main purpose of this legislation is to address the growing issue of synthetic opioids, particularly those referred to as "gas station heroin." It aims to classify specific substances, including MGM-15, MGM-16, synthetic 7-hydroxymitragynine, and mitragynine pseudoindoxyl, as Schedule I controlled substances. This classification indicates that these substances are considered to have a high potential for abuse and no accepted medical use, thereby allowing for stricter regulation and enforcement against their manufacture and distribution.
