Three referees govern CBD content. The FDA says CBD cannot be sold as a dietary supplement or added to food, and it sends warning letters over disease claims. The FTC requires substantiation for any health claim, testimonials included. The platforms mostly refuse the ads. Copy that describes the product instead of promising outcomes clears all three.
The FDA sets the claim ceiling
The agency's standing position is that CBD is not a lawful dietary supplement ingredient or food additive. Its warning letters are public, searchable, and specific — brands get cited for claims about cancer, diabetes, anxiety, and chronic pain, quoted sentence by sentence. Reading a few is the fastest compliance education available, because they show the exact phrasing that triggers enforcement.
The FTC wants receipts
Health claims need competent and reliable scientific evidence, and the FTC has pursued CBD sellers over unsupported ones. Testimonials do not dodge the requirement: a customer quote on your page is your claim. That covers review widgets, social embeds, and influencer copy you republish.
The platform map
Google Ads accepts only LegitScript-certified topical CBD, in a limited set of states. Meta restricts most CBD promotion. Amazon prohibits CBD listings outright. This is the quiet argument for SEO: organic search has no certification gate, and a page that ranks needs no ad account.
Describe, don't diagnose
The compliant register is concrete: spectrum, milligrams per serving, extraction method, hemp sourcing, flavor, batch-linked certificates of analysis. Softeners like "supports" and "promotes" still draw scrutiny when chained to a condition, so the safest structure keeps conditions out of product copy entirely and puts education on separate informational pages.
What this looks like in practice
Before: "Our full-spectrum tincture relieves anxiety, arthritis pain, and insomnia." After: "Full-spectrum tincture, 30 mg CBD per ml, CO2-extracted from Oregon-grown hemp, third-party tested with batch-linked results." The second version ranks on the same queries through its category page and FAQ content, converts on trust signals, and hands a regulator nothing to quote.
Keep a living blocklist
Build a claims blocklist from FDA warning letters and FTC actions: disease names, cure-treat-prevent verbs, outcome promises. Every new page and product upload gets checked against it, and the list gets refreshed quarterly, because the letters keep coming and the cited phrasing keeps evolving.
- FDA warning letters target disease claims; the FTC adds a substantiation requirement that covers testimonials.
- CBD cannot be marketed as a supplement or food additive under the FDA's standing position.
- Ad access is narrow, so organic search does the heavy lifting for most CBD brands.
- A maintained claims blocklist turns compliance from judgment calls into a checklist.
Frequently asked questions
Can I say CBD treats anxiety, pain, or insomnia?
No. Disease claims are the specific thing FDA warning letters cite, and the FTC requires scientific substantiation for any health claim. Even softened phrasing draws scrutiny when it ties the product to a condition.
Can CBD be sold as a dietary supplement?
The FDA's position is that it cannot, and that CBD may not be added to conventional food either. Product pages and schema markup should avoid supplement framing, whatever the label printer allowed.
Where can CBD be advertised?
Narrowly. Google Ads accepts only LegitScript-certified topical CBD in a limited set of states, Meta restricts most CBD promotion, and Amazon prohibits CBD listings. Organic search and email carry most CBD brands as a result.
Do customer testimonials get around claim rules?
No. The FTC treats testimonials you publish as claims you are making, substantiation requirement included. A five-star review saying a tincture cured insomnia belongs in your moderation queue, not on your product page.
What can product copy actually say?
Composition, spectrum, milligrams per serving, extraction method, sourcing, flavor, batch-linked lab results, and routine framing such as when and how people use it. Specific, verifiable, condition-free.
