A bill for an act relating to controlled substances schedules and precursor substances reporting requirements, making penalties applicable, and including effective date provisions.

This bill adds specific synthetic opioids and related compounds to Iowa's most restrictive controlled substances schedule. It directly affects anyone possessing, distributing, or manufacturing these substances, including new fentanyl variants like "Butonitazene" and "Flunitazene," as well as compounds like "Metodesnitazene" and "ethylphenidate." The law establishes penalties: violations can result in a Class B felony (25-year minimum prison term plus $5,000-$100,000 fine), Class C felony, or aggravated misdemeanor. The changes align Iowa's law with federal chemical designations under Title 21 of the Code of Federal Regulations. The bill takes effect immediately upon enactment.
