Got “Reliable and Scientific Evidence” on CBD? A Close Look into the FTC’s Stance on CBD-Related Health Claims and Response From Industry Participants

October 9, 2019


Over the past seven months, and just as recently as three weeks ago, the Federal Trade Commission (“FTC”) has released several warning letters to businesses selling CBD products. These letters concern the FTC’s review of potential violations of the Federal Trade Commission Act of 1914, §§ 41-58, as amended, (the “FTC Act”) made in websites and marketing materials of CBD-related businesses. Participants throughout the CBD industry may take prudence in reviewing not only these health claims called to question by the FTC, but also by how these other industry participants have responded to the FTC’s warning letters.

The FTC and the CRS Evidence Standard

The FTC is an independent federal agency centered on maintaining marketplace competition that benefits both businesses and consumers. The FTC identifies its purpose as, “seek[ing] to protect consumers by enforcing laws and rules that promote truth in advertising and fair business practices, and by educating consumers and businesses about their rights and responsibilities.” FTC Warning Letter to 4Bush Holdings, LLC, dated September 9, 2019.

In its warning letters, the FTC expressed concerns with companies “making false or unsubstantiated advertising claims about the health benefits of products containing cannabidiol (CBD).” The FTC notes that these advertising claims cited by the FTC potentially violate Section 5(a) of the FTC Act, which prohibits unfair or deceptive advertising. Specifically, the FTC Act prohibits businesses from stating in its marketing materials that a product, and as relevant here, a CBD product, provides a prevention, treatment, or cure of a human disease unless such business has “competent and reliable scientific evidence, including, when appropriate, well-controlled human clinical studies substantiating that the claims are true at the time they are made” (“CRS Evidence”). CRS Evidence is required for traditional advertising through the use of a company’s website, product name or metatags, as well as for consumer endorsements or testimonials; even if such testimonial represents the consumer’s honest opinion.

What Type of Advertising and Health-Related Claims Are Being Cited?

  1. Website Reviews

In its warning letters, the FTC has relied on its reviews of businesses’ websites, including social media accounts for statements made regarding the use of CBD for certain human diseases. For example, the FTC has recently cited the following from

CBD has now been clinically proven to:

* * *

  1. Customer Testimonials

The FTC has also flagged statements made by customer testimonials, such as:

  1. Citations of studies

Further, industry participants should be wary of statements made concerning studies, as citation of their findings may not be enough to qualify as CSR Evidence. For example, the FTC has cited the following as a potential violation:

  • “A 2015 study found that CBD may be neuprotective [sic] in adult and neonatal ischemia, brain trauma, Alzheimer’s disease, Parkinson’s disease, Huntington’s chorea, and amyotrophic lateral sclerosis (Lou Gehrig’s disease).”


Compliance Measures

In light of the FTC’s stance presented through its various warning letters related to CBD products, industry participants should carefully review their own websites, customer testimonials and other marketing materials for compliance with the CSR Evidence standard and the FTC’s warning letters. For example, many of the respondents of the warning letters have consistently removed words such as “treatment” and references to diseases. This is true not only for their online materials but also their non-public facing and offline materials as well.   Detailed review of the responses and statements of action made by businesses subject to the warning letters may serve useful as a starting point as industry participants begin to generate compliance policies and procedures to avoid FTC attention.
