There’s a moment in every physician’s career when words begin to carry real weight. A casual suggestion shapes a patient’s decision; a tentative opinion influences treatment. What starts as personal belief gradually acquires authority, affecting real outcomes. Chiles v. Salazar raises a deeper question: at what point do a doctor’s words cease to be protected speech and start becoming regulated actions?
Physicians and Their First Amendment Rights Under Pressure
There are many liminal moments on the journey to becoming a physician: acceptance into medical school, graduation, and the day a patient calls you their doctor. At each stage, an increasing halo surrounds your thoughts and opinions on health concerns. That halo reflects authority and trust but also invites scrutiny. Recently, it seems physicians may be losing not just authority but First Amendment protections as well.
Licensed physicians operate under two conflicting models of speech. As citizens, we retain full First Amendment rights when engaging in public discourse. However, licensure involves professional responsibilities, and speech given in a clinical or advisory role may be regulated by the state to protect the public from harm. The recent Supreme Court ruling in Chiles v. Salazar is less about conversion therapy than about that tension.
The Case
At issue was a Colorado law that banned licensed counselors from engaging in “conversion therapy” with minors, broadly defined to include any effort—through talk therapy or otherwise—to change a client’s sexual orientation, gender identity, behaviors, or attractions, while explicitly allowing supportive or affirming counseling. Kaley Chiles, a licensed therapist, challenged the law, claiming it limits what she can say to clients—permitting affirming discussions of gender identity or sexuality, but banning conversations aimed at changing them. Colorado argued that because Kaley Chiles is a licensed counselor, the state has greater authority over her professional speech. The Court disagreed.
The Chiles decision
Because Chiles is a talk therapist, neither prescribing drugs nor performing procedures, Justice Gorsuch’s majority opinion (8–1) is narrow, addressing only speech, not conduct.
The Court found that Colorado’s law regulates both content and viewpoint. A counselor may support identity exploration or gender transition, but cannot speak in ways that aim to diminish same-sex attraction or align identity strictly with biological sex. The state cannot silence one side of an argument.
Because Chile’s practice involves speech alone and because the law selectively permits one viewpoint while prohibiting another, the Court rejected the Tenth Circuit’s framing of the statute as a neutral regulation of professional conduct. Viewpoint-based restriction on speech requires much more rigorous scrutiny. The opinion concludes with a familiar First Amendment principle: the government cannot prescribe the “correct” view in matters of public and moral controversy. The case was remanded to the lower court.
Speech vs. conduct — the deeper tension
The harder question lies beyond Chiles: where does speech end and conduct begin?
Consider physicians disciplined for advocating ivermectin during COVID. Was the state enforcing medical standards or censoring ideas? Chiles suggests that censorship concerns are real, while regulators argue such restrictions aim to prevent patient harm and misinformation. A physician can publicly say, “I think ivermectin works,” just as another might question vaccination strategies for low-risk populations. These are opinions, and even if mistaken, they fall within the broad scope of First Amendment protection.
Once those opinions are applied to individual patients, however, the analysis shifts. The First Amendment permits falsehoods, poor reasoning, and fringe ideas because its purpose is not to regulate truth, but to prevent government control over speech. The primary distinction isn’t about veracity, but whether speech remains expressive or becomes operational.
When words become actions, the boundary shifts. Prescribing ivermectin, advising an individual patient to avoid vaccination, or giving a specific treatment plan moves speech into conduct. At that point, the state’s regulatory authority becomes clearer.
This distinction appears in everyday practice. A physician might speculate that antibiotics could treat a viral illness—that is, speech. However, writing the prescription constitutes conduct, which is governed by standards of care. While the system allows for a wide range of ideas, it controls how they are carried out.
Influence exists on a spectrum: opinion, advice, instruction, transaction. General statements aimed at a broad audience resemble protected speech. As the connection between conduct and speech tightens, speech becomes subject to regulation. The interval between speech and conduct sharpens this distinction.
The Supreme Court’s decision in Brandenburg v. Ohio illustrates this boundary: speech loses protection when it is intended or likely to produce “imminent lawless action.” However, immediacy alone is insufficient. As speech becomes actionable, and based on reliance, it functions less as mere expression and more as conduct.
Employment and institutional power
For the growing number of employed physicians, speech is no longer purely personal; it becomes a function of their employer.
Hospitals and health systems have broad authority to regulate both the actions and speech of their employees. Treatment protocols, quality control, and risk management shape what can be said and done. While outside the workplace, physicians regain some independence, when speech conflicts with standards, reputation, or liability concerns, institutions do not hesitate to control employee speech.
Influencers and supplements
If clinical settings blur speech and action, digital platforms, beyond traditional practice, dissolve the boundary even further. Influencers raise the same unanswered question: when speech consistently leads to action, can it still be considered merely speech?
The health influencer’s statement that “this supplement supports immunity” is protected speech. Saying “you should take this” leans toward a recommendation; linking that recommendation to a product transforms it into a transaction. Speech becomes a gateway to commercial, regulated conduct.
Supplements, because they are loosely regulated compared to pharmaceuticals, amplify the problem. Oversight shifts toward the speech surrounding labeling, advertising, and claims, placing pressure directly on the relationship between words and action.
The First Amendment protects physicians’ speech in the marketplace of ideas, but medicine is a realm of action, responsibility, and consequence. The real dividing line is whether words are simply expressive or actively guiding behavior. As medicine increasingly blurs with media, influence, and commerce, the uncomfortable truth for physicians is that they can say nearly anything—until someone is expected to act on it.
