How do you spot CBD scams and misleading claims?
TL;DR — What the Evidence Shows
CBD marketing often makes claims not supported by evidence. Some claims are illegal under FTC and FDA rules. Knowing the red flags helps you avoid products that may be unsafe or a waste of money.
Red flags to watch for
These warning signs come from FDA and FTC enforcement actions, peer-reviewed product quality research, and documented marketing patterns targeting older adults.
Claims to "cure," "treat," or "heal" arthritis or any disease
These claims are illegal under FDA and FTC rules. The FDA has issued 79 or more warning letters since 2015 to companies making disease treatment claims for CBD. The FTC's Operation CBDeceit (December 2020) sanctioned six companies specifically for claims including "medically proven" pain relief and "more effective than OxyContin." No CBD product is approved to treat any disease.

No Certificate of Analysis (COA) available
A Certificate of Analysis is a third-party lab report showing what is actually in the product. If a company does not provide one for your specific product batch, you have no independent way to verify the CBD content, THC content, or whether the product contains lead, pesticides, or other contaminants. Studies find that about 4 out of 10 edible CBD products contain detectable lead. A COA is the only consumer protection available in the absence of FDA premarket review.

Health claims on product labels or packaging
CBD products cannot legally claim to treat, diagnose, cure, or prevent any disease on their labels. If the product label says something like "relieves arthritis pain," "treats inflammation," or "supports joint health" — particularly without a required FDA disclaimer — the company may be violating federal law.
Celebrity endorsements presented as medical evidence
Fake celebrity endorsements are a documented scam pattern in the CBD market. If a celebrity's name or image appears in a CBD advertisement but not on that celebrity's verified social media or official channels, the endorsement is likely fabricated. Even real celebrity endorsements are not medical evidence — they are marketing.
Pressure to buy quickly (urgency language, limited-time offers)
Language like "only 3 left," "offer expires tonight," or "free trial — just pay shipping" is designed to prevent you from doing research. Free trial offers that convert to recurring charges without clear disclosure are documented scam patterns that disproportionately affect older adults. The FTC has brought cases against companies using these tactics.
Prices significantly below market rate
Quality CBD extraction, testing, and packaging has real costs. Products priced far below competitors may contain less CBD than labeled, may use cheaper extraction methods that leave residual solvents, or may not be third-party tested at all. Studies find that products priced at the low end are more likely to be mislabeled.
"Proprietary blend" without specific cannabinoid content
A product that lists a "proprietary hemp blend" but does not disclose how much CBD it contains is not verifiable. Without a specific CBD content claim and a COA to back it up, you do not know what you are buying.
Claims of FDA approval
No CBD product is FDA-approved for arthritis, chronic pain, or any musculoskeletal condition. The only FDA-approved CBD product is Epidiolex, a prescription drug for specific seizure disorders. Any claim that a CBD supplement or topical is "FDA-approved" is false.
"Big Pharma doesn't want you to know" or similar conspiracy framing
Academic research identifies conspiracy framing as a hallmark of supplement marketing. The FTC's consumer guidance specifically warns against "miracle" health claims paired with anti-establishment language. This framing is designed to discourage you from checking with your doctor or doing independent research.

What do legal claims look like, and what is illegal?
CBD companies can make structure/function claims — statements about how a substance may affect body processes — but only if the claim is substantiated, accompanied by a required FDA disclaimer, and does not cross into disease territory.
Legal claim examples
(structure/function claims with required disclaimer)
- ✓ "May support joint comfort"
- ✓ "Supports healthy inflammatory response"
- ✓ "Promotes relaxation"
These are only legal when accompanied by the required FDA disclaimer: "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease."
Note: Even legal structure/function claims must be substantiated. For CBD, substantiation is limited given the current evidence base.
Illegal claim examples
(disease claims — prohibited by FDA and FTC)
- ✗ "Cures arthritis pain"
- ✗ "Clinically proven to treat osteoarthritis"
- ✗ "FDA-approved for joint pain"
- ✗ "Doctor recommended for arthritis"
- ✗ "Medically proven to reduce inflammation"
- ✗ "Safe for all users"
The FTC flagged "safe for all users" as specifically deceptive in its 2020 enforcement actions. CBD has documented drug interactions and potential liver effects.
How to report problematic products
If you encounter a product or company that appears to be making illegal claims or engaged in deceptive practices, there are several ways to report it.
FDA MedWatch — adverse events and safety concerns
Report health problems, unexpected reactions, or safety concerns caused by a CBD product. fda.gov/safety/medwatch
FTC — false advertising complaints
Report companies making unsubstantiated health claims, fake testimonials, or misleading advertising. reportfraud.ftc.gov
State Attorney General — fraud
Report subscription traps, unauthorized charges, or other deceptive business practices to your state AG's consumer protection office. Search "[your state] attorney general consumer complaint."
Better Business Bureau — business complaints
For unresolved refund disputes, shipping issues, or misleading advertising. bbb.org/file-a-complaint
CBD interacts with many common medications
- Blood thinners (warfarin): CBD can increase bleeding risk by raising INR levels
- Statins, blood pressure medications, and immunosuppressants may also be affected
- CBD inhibits the same liver enzymes that process many prescription drugs
