Bill
HF 182
HF 182 updates Iowa’s controlled-substances schedules to add fentanyl analogs, nitazenes, and synthetic cannabinoids; broadens precursors and applies penalties immediately.
Purpose
- HF 182 updates Iowa’s controlled‑substances law by adding numerous specific novel/illicit drugs and related chemical precursors to the state schedules, revising the listed anabolic/androgenic agents, clarifying certain precursor definitions and exemptions, and making existing penalties for controlled‑substance violations applicable to the newly listed substances. The Act took immediate effect upon enactment (signed by the Governor on March 28, 2025).
Key provisions and changes
- Adds numerous fentanyl analogs and related synthetic opioids to the controlled‑substances schedules (examples added include alpha’‑Methyl butyryl fentanyl; 2’,5’‑Dimethoxyfentanyl; 3‑Furanyl fentanyl; isovaleryl fentanyl; meta‑fluorofentanyl; several furanyl/fluoro variants).
- Adds several potent benzimidazole “nitazene” class opioids (examples: etodesnitazene/etazene; N‑pyrrolidino etonitazene/etonitazepyne; protonitazene).
- Adds a set of synthetic cannabinoids and related designer cannabinoids (examples: ADB‑BUTINACA; MDMB‑4en‑PINACA; ADB‑4en‑PINACA; MDMB/MDMB‑BUTICA variants).
- Adds certain synthetic stimulants/cathinones (example included: 3‑MMC / 3‑methylmethcathinone) and substituted cathinone alpha‑PiHP.
- Expands the list of designer benzylindazole/piperazine derivatives (example: 2‑Methyl AP‑237).
- Revises and expands the list of anabolic/androgenic agents (many specific steroid compounds added or re‑specified in section 124.208).
- Adds zuranolone to the list in section 124.210 (new paragraph bh).
- Modifies precursor/chemical definitions in chapter 124B:
- Restates iodine threshold language (“Iodine in concentrations greater than 2.2 percent”).
- Broadens the listing for N‑phenylpiperidin‑4‑amine (4‑AP) to expressly cover its amides, carbamates, halides, salts, and combinations.
- Adds an explicit exemption in 124B.6(5) allowing sale/transfer/furnishing/receipt of chemical mixtures that are identified as exempt under federal regulation (aligns state treatment with federal exemptions).
- Makes penalties for controlled‑substance offenses under existing Code provisions applicable to the newly listed substances (the bill incorporates these substances into the statutory schedule framework that carries attendant criminal penalties).
Who is affected
- Law enforcement and prosecutors: new substances are prosecutable under Iowa controlled‑substance statutes.
- Chemical suppliers, distributors, retailers: expanded precursor definitions and scheduling may restrict sale and distribution of listed chemicals and mixtures; some mixtures identified as federally exempt are expressly accommodated.
- Healthcare providers, pharmacies, researchers and manufacturers: substances newly scheduled (including zuranolone and certain steroids) may face tighter prescribing, dispensing, research, and handling requirements.
- Athletes and sports organizations: changes to anabolic agent listings affect substances tested and sanctioned under state rules.
- Public health and harm‑reduction stakeholders: measures target emerging illicit opioids and designer drugs associated with overdose risk.
Procedural / timeline notes
- Introduced January 30, 2025.
- Passed House (yeas 92–0) on February 20, 2025; substituted for SF 305 and passed Senate (yeas 48–0) on March 12, 2025.
- Enrolled and signed by the Governor March 28, 2025; effective immediately on enactment.
Practical effect
- HF 182 updates Iowa’s controlled‑substance schedules to specifically name a range of emerging designer opioids, cannabinoids, stimulants, and steroidal compounds, bringing them within the state’s criminal and regulatory framework. The law also tightens precursor definitions while recognizing federal exemptions for certain chemical mixtures, requiring affected parties to update compliance, reporting, procurement, and handling practices accordingly.
