CBD ads with health claims: do they trick shoppers?
NCT ID NCT06800066
First seen Jun 27, 2026 · Last updated Aug 28, 2026 · Updated 1 time
Summary
This study looked at whether CBD ads with health claims (like curing cancer) make people more likely to buy CBD products. 460 adults completed a shopping task in a mini mart, seeing either CBD ads or non-CBD ads. Researchers tracked how many bought a CBD product and what they thought about CBD's benefits.

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help regulators understand how unsubstantiated CBD health claims influence consumer choices.
- What could go wrong
- This is a completed behavioral study, not a treatment trial. Results may not reflect real-world shopping behavior outside a controlled mini mart.
