Whether a naturopathic doctor can write prescriptions depends entirely on the state. Roughly 26 U.S. jurisdictions license or register NDs, and among those, prescriptive authority runs from Oregon’s near-complete formulary including controlled substances down to Maryland’s list of essentially five items. Three states — Florida, South Carolina, and Tennessee — ban naturopathic practice outright, and about half the country has no licensing framework at all, meaning an ND practicing there has no legal authority to prescribe anything.1Connecticut General Assembly. Naturopath Licensing and Prescriptive Authority in Other States
Before prescribing enters the picture at all, the ND has to be licensed in a state that recognizes the profession.2Bastyr University. Becoming a Licensed Naturopathic Doctor Chapter 2 In a state with no licensing, the title “naturopath” carries no legal scope of practice, and any prescription written by that person is legally invalid.
States With Broad Prescriptive Authority
Oregon has the widest scope in the country. Licensed NDs there can prescribe from nearly the entire AHFS drug formulary unless a specific class is excluded by administrative rule. That includes controlled substances across multiple schedules — NDs who prescribe them must hold a DEA registration — and it includes buprenorphine and other medications used to treat opioid use disorder.3Oregon Board of Naturopathic Medicine. Prescribing Authority, Licensure Requirements and Formulary Compendium
Arizona is also relatively broad but drawn tighter. Arizona NDs can prescribe controlled substances in Schedules III through V, plus morphine from Schedule II and any drug reclassified from Schedule III to II after January 1, 2014. They cannot prescribe most Schedule I or II substances, cannot dispense Schedule II opioids, and cannot prescribe cancer or antipsychotic medications.4Arizona Legislature. Arizona Revised Statutes 32-1501
States With Limited or Restricted Authority
Most licensing states sit in a middle zone where NDs can prescribe some medications but face meaningful restrictions. The restrictions take different shapes.
Washington
Washington NDs can prescribe legend drugs (prescription medications), immunizations, contraceptive devices, and nonlegend natural medicines like vitamins and botanical preparations. Controlled substances are much narrower: only codeine products and testosterone products in Schedules III through V, and only after the state board individually approves the ND to prescribe them. Washington NDs also cannot treat cancer except in collaboration with an MD or DO.5Washington State Legislature. WAC 246-836-210 Authority to Use, Prescribe, Dispense and Order
Colorado
Colorado NDs can prescribe, dispense, and administer medicines from a defined naturopathic formulary. Controlled substances listed under the federal Controlled Substances Act are explicitly excluded.6Justia Law. Colorado Code 12 Health Care Article 37.3 Section 12-37.3-105 The formulary covers natural therapeutics, some hormones, and certain prescription medications, but the no-controlled-substances line is absolute.
Maine
Maine phases prescriptive authority in. Before an ND can independently prescribe noncontrolled legend drugs, they must complete a 12-month collaborative relationship with a licensed MD or DO. During that year, the ND keeps copies of every prescription written, meets with the collaborating physician quarterly for review, and reports completion of the arrangement to the licensing board at renewal.7Maine State Legislature. Maine Revised Statutes Title 32 Section 12522 – Scope of Practice After that year, independent prescribing of noncontrolled legend drugs is allowed.
Maryland
Maryland is among the most restrictive. Licensed NDs can prescribe or dispense only auto-injectable epinephrine, prescription oxygen, diaphragms and cervical caps, FDA-regulated nonprescription drugs, and FDA-regulated nonprescription devices. All other prescription drugs and all controlled substances are excluded by rule.8Maryland Board of Physicians. Naturopathic Formulary In practice, a Maryland ND has almost no conventional prescribing power.
States Where NDs Cannot Prescribe At All
A license doesn’t always come with prescribing rights. Connecticut licenses naturopathic physicians but limits their practice to natural substances and natural therapies, with no prescriptive authority for legend drugs or controlled substances. The state’s naturopathic physician association has asked the legislature for prescriptive authority, and that request has not been granted.1Connecticut General Assembly. Naturopath Licensing and Prescriptive Authority in Other States
Beyond that, roughly 24 states and territories have no ND licensing framework, and Florida, South Carolina, and Tennessee prohibit naturopathic practice by statute. In every one of those jurisdictions, an ND has zero prescriptive authority regardless of their training or credentials.
The Federal Layer: DEA Registration
State authority to prescribe controlled substances is only half the story. Any ND who prescribes, administers, or dispenses controlled substances also has to hold a federal DEA registration, and the DEA recognizes naturopathic physicians among its categories of registered practitioners.9Drug Enforcement Administration. Required Training with Respect to Substance Use Disorders for DEA-Registered Practitioners
Since 2023, non-physician practitioners applying for or renewing DEA registration must attest to completing at least eight hours of training on the treatment and management of substance use disorders. It’s a one-time requirement, and NDs keep their training certificates on file rather than submitting them with the application.9Drug Enforcement Administration. Required Training with Respect to Substance Use Disorders for DEA-Registered Practitioners Without DEA registration, no ND can legally prescribe a controlled substance, no matter what state law permits.
Telehealth Across State Lines
Telehealth creates a real problem here. When an ND treats a patient by video or phone, the ND is considered to be practicing in the state where the patient is physically located, not where the ND’s office is. The ND must hold a valid license in the patient’s state, and the more restrictive scope of practice between the two states applies.
The Oregon-to-Washington case makes this concrete. An Oregon ND with broad prescriptive authority treats a patient sitting in Washington. Oregon allows prescribing across most controlled substance schedules; Washington restricts NDs to codeine and testosterone products. Washington’s rules govern. A prescription that exceeds Washington’s scope is invalid, and the ND may be practicing outside their legal authority.5Washington State Legislature. WAC 246-836-210 Authority to Use, Prescribe, Dispense and Order If the patient is in a state that doesn’t license NDs at all, the ND cannot legally treat them remotely.10Telehealth.HHS.gov. Licensing Across State Lines
Will Insurance Cover an ND Prescription?
A valid prescription and a covered prescription are two different things. Original Medicare (Parts A and B) does not cover services provided by naturopathic doctors, and Medicare Supplement plans follow the same rule. Some Medicare Advantage plans include limited naturopathic coverage, but it’s uncommon; contact the plan directly to find out.
Private insurance varies widely. Some plans in licensing states cover ND visits and process pharmacy claims for ND-written prescriptions. Others exclude naturopathic services entirely or require a supplemental rider. Before filling a prescription from an ND, call your insurer and ask two specific questions: whether services from a naturopathic doctor are covered under your plan, and whether prescriptions written by an ND are eligible for pharmacy benefits.
How to Check Your ND’s License and Scope
To confirm that a specific ND is licensed and to see what they’re authorized to prescribe, contact your state’s naturopathic licensing board or medical board. Most maintain online license verification tools where you can search by name and see the provider’s license status, disciplinary history, and any scope restrictions.11Naturopathic Physicians Medical Board. Naturopathic Physicians Medical Board – Arizona If your state has no naturopathic licensing board, that itself is the answer: NDs aren’t formally recognized there and have no prescriptive authority.
The distinction between a licensed naturopathic doctor and someone calling themselves a “naturopath” matters. Licensed NDs complete a four-year, graduate-level program at a school accredited by the Council on Naturopathic Medical Education and pass both parts of the Naturopathic Physicians Licensing Examination (NPLEX).2Bastyr University. Becoming a Licensed Naturopathic Doctor Chapter 2 Someone practicing without those credentials, or in a state that doesn’t license the profession, has no legal authority to prescribe medications at all.
