Ketamine Therapy in Washington

Washington State operates under a well-established regulatory framework governing the administration of ketamine for both anesthetic and therapeutic purposes. Ketamine remains a Schedule III controlled substance under both federal law and Washington State's Uniform Controlled Substances Act (RCW 69.50), meaning that any practitioner prescribing or administering it must hold a valid DEA registration and comply with strict prescribing, record-keeping, and storage requirements. The Washington State Department of Health (DOH) oversees licensure of medical professionals and facilities, and clinics offering ketamine infusion therapy must ensure that all administering providers — typically anesthesiologists, nurse anesthetists (CRNAs), or other qualified physicians — are appropriately licensed and credentialed within the state.

At the clinical level, intravenous ketamine infusions are considered an off-label use of an FDA-approved anesthetic, which means there is no specific Washington State statute exclusively governing ketamine therapy clinics as a distinct category. Instead, these facilities are subject to the same regulations that apply to outpatient medical practices and, in some cases, ambulatory surgical centers, depending on the scope and complexity of services offered. Providers must adhere to the Washington Administrative Code (WAC) standards for patient safety, informed consent, and documentation. Many clinics also follow voluntary guidelines issued by professional organizations such as the American Society of Ketamine Physicians, Psychotherapists and Practitioners (ASKP3) and the American Society of Anesthesiologists to ensure best practices.

Washington has also seen growing interest in the integration of ketamine with psychotherapy, sometimes referred to as ketamine-assisted psychotherapy (KAP). Mental health providers participating in KAP must hold a valid Washington State mental health license (such as an LCSW, LPC, or licensed psychologist) and operate within their defined scope of practice. While they may provide the therapeutic component of treatment, only licensed medical providers may administer the ketamine itself. Patients in Washington should be aware of the following key regulatory considerations when seeking ketamine therapy:

• All ketamine must be administered by or under the direct supervision of a licensed medical provider with appropriate DEA registration.
• Clinics must obtain thorough informed consent and maintain detailed medical records in compliance with Washington DOH standards.
• Facilities operating with sedation or anesthesia services may be subject to additional ambulatory care facility regulations under WAC 246-330.
• Telemedicine prescribing of ketamine for at-home use (such as oral or nasal formulations) is subject to evolving federal and state telehealth regulations, including prescriber-patient relationship requirements.

The regulatory landscape for ketamine therapy in Washington continues to evolve, particularly as research into its efficacy for treatment-resistant depression, PTSD, and chronic pain expands. Prospective patients are strongly encouraged to verify the credentials of any clinic and its providers through the Washington State Department of Health's online license verification portal before beginning treatment. Choosing a clinic that adheres to nationally recognized clinical protocols and maintains transparent communication about its regulatory compliance is an important step in ensuring both safety and quality of care.
