The Stop the Opioid Pill Presser and Fentanyl Act (STOPP Act) aims to enhance the regulation of machines used for producing pills and capsules, specifically targeting the opioid crisis and illegal fentanyl production. By addressing regulatory gaps, the Act seeks to prevent the misuse of these machines in the manufacturing of controlled substances, thereby protecting public health and safety. Key provisions of the STOPP Act include new regulations for tableting and encapsulating machines, requiring manufacturers, distributors, and importers to register with the Attorney General.
