Why Regulation Matters Before You Book

Ketamine clinics have multiplied across the country in the last decade. The pace of growth has outrun the public’s understanding of what regulates them, who is allowed to give an infusion, and what a patient should expect from the clinic itself. In Tennessee specifically, the answer involves more than one agency. It involves federal controlled-substance law, state medical and nursing boards, and professional standards that any reputable office-based anesthesia practice should be following.

Knowing the framework matters for two reasons. First, it tells you what is legal and what is not, so you can recognize a legitimate clinic when you see one. Second, it gives you a vocabulary for asking questions before you book. A clinic that operates inside the framework will answer those questions easily. A clinic that does not should give you pause.

Ketamine is FDA-approved as an anesthetic; its use for depression, PTSD, anxiety, and chronic pain is off-label. That fact is the starting point for understanding everything else. Off-label is legal, common, and well-supported in the medical literature—but it places the responsibility for safe practice squarely on the clinic and the clinician.

Federal: DEA Schedule III Status and Registration

At the federal level, ketamine is classified by the U.S. Drug Enforcement Administration as a Schedule III controlled substance. Schedule III status means the drug has accepted medical use, a moderate to low potential for physical dependence, and a higher potential for psychological dependence than schedules above it. Ketamine has been on Schedule III since 1999.

That classification carries practical requirements. Any clinician or facility that orders, stores, or administers ketamine must be registered with the DEA. The registration is tied to a specific practice location. Controlled-substance ordering, dispensing, and disposal must be documented in records that the DEA can audit. Storage must be secure, typically in a locked cabinet or safe with access limited to authorized personnel.

For patients, the takeaway is straightforward. A legitimate ketamine clinic operates under an active DEA registration. The medication does not arrive through informal channels. Inventory is tracked. If something is unaccounted for, the clinic is required to report it.

Tennessee Board of Medical Examiners—Physician Oversight

Physicians who prescribe and oversee ketamine therapy in Tennessee are licensed and regulated by the Tennessee Board of Medical Examiners. The board sets the standards for medical practice in the state, handles complaints, investigates allegations of improper care, and disciplines physicians who fall short of the standard of care.

For ketamine clinics specifically, the board’s general standards on prescribing controlled substances, on the practice of medicine, and on appropriate documentation all apply. The board does not publish a separate ketamine clinic rulebook. Instead, ketamine practice is held to the same expectations as any other use of a Schedule III controlled substance: a legitimate medical purpose, an appropriate physician-patient relationship, informed consent, monitoring, and recordkeeping.

Patients can verify the licensure status of any Tennessee physician through the state’s online license verification system. A clinic that cannot point you to its medical director’s license, or to the credentials of its prescribing clinicians, is a clinic worth questioning.

Tennessee Board of Nursing and CRNA Scope

Many ketamine clinics in Tennessee, including Music City Ketamine, are CRNA-led. Certified Registered Nurse Anesthetists are advanced practice registered nurses with graduate-level training in anesthesia. The Tennessee Board of Nursing licenses and regulates registered nurses and APRNs, and CRNA practice falls under that umbrella.

Tennessee requires APRNs to practice in a collaborative relationship with a physician. The exact contours of that relationship are defined by board rules and by the agreements between individual APRNs and their collaborating physicians. For a CRNA running ketamine infusions, this means a physician collaboration is in place alongside the CRNA’s own anesthesia training and the clinic’s DEA registration. CRNA training is specifically focused on anesthesia, including airway management, hemodynamic monitoring, and the safe use of dissociative agents like ketamine.

That training is the reason CRNA-led ketamine clinics are common nationally. Anesthesia is what CRNAs do. Administering a sub-anesthetic dose of ketamine, monitoring vital signs, recognizing adverse reactions, and intervening if needed are core competencies of the credential.

AANA Standards for Office-Based Anesthesia

The American Association of Nurse Anesthesiology publishes practice considerations for office-based anesthesia. These are the professional standards that a CRNA-led ketamine clinic should be meeting, regardless of whether a state board has codified them line by line. AANA’s 2023 office-based anesthesia practice considerations describe the elements of safe practice in non-hospital settings: credentialed anesthesia providers, continuous physiologic monitoring, immediate access to resuscitation equipment, emergency medications on site, and a written plan for transferring patients to a higher level of care if needed.

For ketamine specifically, this translates into a recognizable standard of care. Continuous pulse oximetry, blood pressure, and heart rate monitoring during every infusion. ACLS-trained staff in the building. Suction, oxygen, airway equipment, and reversal or rescue medications immediately available. A consent process, a screening process, and documentation that meets the same expectations as any office-based procedure under sedation.

AANA standards are not a Tennessee statute. They are the professional baseline. A clinic that meets them is operating responsibly. A clinic that does not is operating outside the standard of care, even if no one has reported it yet.

ASKP3 Practice Guidelines and Off-Label Use

The American Society of Ketamine Physicians, Psychotherapists & Practitioners (ASKP3) is the professional society that has done the most to formalize practice expectations for ketamine clinics. ASKP3’s consensus practice guidelines address staffing, monitoring, screening, dosing ranges for psychiatric and pain indications, contraindications, and aftercare. They are not law. They are the field’s self-imposed standard, and they align closely with what AANA expects from any office-based anesthesia practice.

ASKP3 guidelines also clarify what off-label means. The FDA approved ketamine in 1970 as an anesthetic. Spravato (esketamine) was approved in 2019 for treatment-resistant depression and later for major depressive disorder with acute suicidal ideation. Every other psychiatric and chronic-pain use of racemic ketamine is off-label. Off-label prescribing is legal and routine in U.S. medicine, but it requires the prescribing clinician to have a legitimate medical basis, to obtain informed consent, and to follow the standard of care for the actual use.

Tennessee permits off-label use of ketamine when prescribed by a licensed clinician acting within scope. That is the legal foundation for every reputable ketamine clinic in the state.

Controlled-Substance Storage, Records, and Emergency Readiness

The day-to-day operational rules for a Tennessee ketamine clinic come from the intersection of DEA regulations and state pharmacy and controlled-substance rules. Storage must be secure. Inventory must be documented at the unit level. Disposal of unused medication must be witnessed and recorded. Reporting requirements apply to losses, thefts, and significant discrepancies.

Emergency readiness is part of the same picture. AANA standards and ASKP3 guidelines both call for resuscitation equipment, supplemental oxygen, suction, airway devices, and emergency medications to be available in every treatment room or immediately accessible. Staff should be ACLS-trained. The clinic should have a written plan for handling adverse events, including criteria for activating emergency medical services and transferring a patient to a hospital.

Adverse events with sub-anesthetic ketamine in a properly screened population are uncommon. The 2024 systematic literature on office-based ketamine reports significant adverse events in low single-digit percentages, generally cardiovascular and resolving with standard management. The point of the readiness standard is not that something is likely to go wrong. The point is that if it does, the clinic is prepared.

The Bigger Picture

Tennessee does not regulate ketamine clinics through a single statute or licensing category. It regulates them through the same overlapping system that governs any office-based controlled-substance practice: federal DEA rules, state medical and nursing boards, pharmacy law, and the professional standards published by AANA and ASKP3. A clinic that takes the framework seriously will look like a medical practice, not a wellness pop-up. The credentials are real. The monitoring is real. The records are kept.

For patients, the framework is also a tool. Use it. Ask the questions. The answers tell you most of what you need to know before you ever sit in the chair.
