The FDA has sent warning letters to CBD companies for claiming products treat diseases, the FTC requires substantiation for any health benefit you state, and state cannabis regulators bar therapeutic claims in licensee marketing. Sell the strain, the terpenes, and the lab results — not a medical outcome.
Three enforcers, one message
Health claims on cannabis and CBD content draw three separate authorities. The FDA treats a product marketed to treat or prevent disease as an unapproved new drug under the Food, Drug, and Cosmetic Act, and its public warning letters to CBD sellers have repeatedly quoted website and social copy claiming help with conditions like cancer, Alzheimer's, and anxiety. The FTC requires competent and reliable scientific evidence behind health-benefit claims and has co-signed FDA letters. And state regulators — the Colorado MED and New York's OCM among them — prohibit therapeutic or curative claims in licensee advertising outright.
The vocabulary that triggers letters
The dangerous words are the medical ones: treat, cure, prevent, relieve, plus any named condition. Helps with insomnia is a drug claim. So is reduces inflammation, and so is for anxiety relief. The pattern in published FDA letters is consistent: the agency quotes the seller's own product pages, blog posts, and social captions back at them. Blog content is not a safe harbor when it links to or surrounds products for sale.
Testimonials are your claims too
The FTC's Endorsement Guides make a republished customer statement the advertiser's own claim. A five-star review saying a tincture fixed someone's arthritis, showcased on your product page or reposted to your feed, is you claiming the product treats arthritis. Curated review widgets, influencer posts you paid for or reshared, and quote graphics all count. Let raw reviews sit unedited in a reviews section; do not promote the medical ones.
What this looks like in practice
A product page reads our best gummy for sleep and anxiety. The compliant rewrite sells the same product on facts: an indica-leaning blend, myrcene and linalool forward, 5 mg THC per piece, third-party COA linked. Customers hunting for a nighttime product still find it through the strain type and terpene description, and nothing on the page asserts a medical outcome. The rewrite usually ranks better too, because it carries more specific, searchable detail than the vague promise did.
Educational content without the liability
You can still write about cannabinoid research. The line runs between education and product marketing: an article summarizing published studies, with sources cited and no tie to your SKUs, sits differently than the same sentences on a checkout page. Keep research content in a separate blog section, attribute findings to the studies rather than asserting them as product benefits, and skip the internal links that turn an article into an implied claim for a specific item.
Key takeaways
- FDA warning letters target disease claims; the FTC requires substantiation; state regulators like the Colorado MED and New York OCM ban therapeutic claims in licensee ads.
- Treat, cure, prevent, relieve, and named conditions are drug-claim vocabulary anywhere on your site.
- Republished testimonials become your claims under the FTC Endorsement Guides.
- Sell composition instead: strain type, terpenes, potency, linked lab results.
Frequently asked questions
Can I say CBD helps with anxiety if studies exist?
Not on a page selling your product. The FDA treats a disease or condition claim as marketing an unapproved drug regardless of the research you could point to, and the FTC requires substantiation you are unlikely to hold for your specific formulation. Discuss research in standalone educational content, cited and unlinked from your catalog.
Do customer reviews count as health claims?
They do once you use them in marketing. Under the FTC Endorsement Guides, a testimonial you feature, repost, or excerpt becomes your own claim. Unfiltered reviews sitting in a review section are a different situation than an arthritis claim you pulled into a product-page banner.
What can I legally say about effects?
Describe the product: strain lineage, cannabinoid potency, terpene profile, flavor, onset format. Common descriptors like relaxing or energizing sit in a grayer zone than medical claims, and the safest pattern is composition plus lab results rather than promised outcomes. Your state's marketing rules set the exact line.
Does this apply to blog posts or just product pages?
Both. FDA letters routinely quote blog and social content, and the agency reads the whole website as marketing when products are for sale on it. A post titled best strains for pain that links to your menu functions as a product claim. Keep educational pieces cited, general, and unconnected to your SKUs.
