Healthcare providers, including chiropractors, navigate a complex landscape of advertising regulations designed to protect the public and uphold the integrity of the profession. While the First Amendment grants a constitutionally protected right to commercial speech, this right is conditional; advertising must not concern unlawful activity and must not be misleading. Both state practice acts and federal consumer protection laws, like the Federal Trade Commission Act (FTCA), empower licensing boards and agencies to penalize "false," "misleading," or "unethical" advertising.

Crucially, all advertised claims must be truthful and substantiated with valid research, avoiding unjustified expectations or guarantees of a cure. Providers are held accountable for all advertising appearing in their name, even if not personally created. Testimonials face strict guidelines: they must reflect generally achievable results, be objectively substantiated, involve personally treated patients, and disclose any compensation. Furthermore, testimonials should be current and backed by signed permissions. Given these stringent requirements, regular review of marketing materials by legal counsel knowledgeable in state-specific laws is highly recommended to ensure compliance.
