A physician who certifies a patient for a state medical marijuana program is relying on more than professional judgment. The physician is also relying on a legal distinction between recommending marijuana and dispensing it, one that protects the physician's DEA registration, the credential behind every other controlled-substance prescription the practice writes. That scheduling landscape shifted in April 2026, when the Department of Justice moved marijuana sold under a state medical marijuana license, along with marijuana in FDA-approved drug products, into Schedule III of the Controlled Substances Act. Marijuana outside those categories, including unlicensed and recreational marijuana, remains Schedule I. A registration suspended or revoked over a misunderstanding about cannabis can end a practice's ability to prescribe anything else.
Recommending Cannabis Is Protected Medical Judgment
The Ninth Circuit's 2002 decision in Conant v. Walters affirmed a permanent injunction barring the federal government from revoking a physician's DEA registration, or opening an investigation, solely because the physician recommended marijuana to a patient based on a sincere medical judgment. The court treated the recommendation itself as protected speech between doctor and patient, distinct from the act of dispensing marijuana. That protection has held for more than two decades, and it is the legal foundation underneath every state medical marijuana program's certification process.
Marijuana's Current Scheduling Status
Marijuana's federal status is no longer uniform. The April 2026 order moved marijuana sold under a qualifying state medical marijuana license, and marijuana contained in FDA-approved drug products, from Schedule I to Schedule III, effective April 28, 2026. Marijuana outside those two categories, including unlicensed and recreational marijuana, remains Schedule I. A separate, broader proceeding to move all marijuana to Schedule III was argued before a DEA administrative law judge during the summer of 2026 and remained pending, with no final recommendation issued, as of November 2026. Which schedule applies to a given patient's marijuana currently turns on whether it is sourced under a state medical license.
A State Certification Does Not Require DEA Registration
The April 2026 order preserves the certification model that state medical marijuana programs already use. A practitioner who signs a state-law certification, the document state law treats as sufficient for a patient to obtain marijuana, is not thereby required to hold a separate DEA registration to handle marijuana. Registration is required of practitioners who go further and directly manufacture, distribute, or dispense marijuana themselves, rather than simply issuing a recommendation for a patient to obtain it through a state-licensed source. For a physician whose role stops at the recommendation, that act stays outside the registration requirements that otherwise accompany a Schedule III substance.
A physician's DEA registration is protected when the conduct at issue is a bona fide medical recommendation, not simply because the underlying substance is marijuana.
What Still Draws DEA Scrutiny
The legal protection for recommending marijuana is narrow. It covers the recommendation itself, not everything a practitioner does around it. DEA enforcement against a practitioner's controlled-substance registration proceeds through escalating stages: a letter of admonition (see Responding to a DEA Letter of Admonition), then a DEA order to show cause, and in the most serious matters, an immediate suspension order. A certifying physician who also holds a financial stake in a dispensary, who directs patients to a specific dispensary in exchange for compensation, or whose broader prescribing of other controlled substances already shows red flags, faces a different and higher level of exposure than the Conant protection was built to cover.
Why Early Legal Counsel Is Critical
It is critical that physicians and other practitioners promptly retain experienced healthcare defense counsel upon receiving any DEA inquiry, subpoena, or notice connected to a controlled-substance registration, including one that touches a medical marijuana certification. Early legal intervention can protect the practitioner's rights, ensure an appropriate response to the agency's request, avoid inadvertent admissions, preserve relevant defenses, and allow counsel to communicate with investigators on the practitioner's behalf. Delaying legal representation can significantly affect the outcome of a matter and expose the practitioner to risk that a timely response could have avoided.
