Scope Details
Maine NDs have broad scope of practice including prescriptive authority for substances on the naturopathic formulary, minor surgery, natural childbirth attendance, IV therapy, diagnostic testing, botanical medicine, nutritional counseling, and naturopathic acupuncture with additional certification.
Naturopathic doctor scope of practice varies enormously by state. States with the broadest scope (Oregon, Washington, Arizona, Vermont, Montana) allow prescriptive authority including some controlled substances, minor surgery, natural childbirth attendance, and IV therapy. Other states have more limited scope covering diagnostic testing, nutritional counseling, botanical medicine, and physical medicine only. In unlicensed states, naturopathic practice may be unregulated or prohibited.

Prescriptive authority for naturopathic doctors varies significantly by state. States with the broadest authority (Oregon, Washington, Arizona, Vermont, Montana) allow NDs to prescribe most non-controlled substances and some controlled substances with DEA registration. Other states limit NDs to a defined formulary of natural and synthetic substances. DEA registration may be available in states with prescriptive authority for controlled substances. Always verify current prescriptive authority with the state licensing board.
