Study tests if pot ads lure anxious users into buying more THC
NCT ID NCT07216911
First seen Jun 25, 2026 · Last updated Aug 05, 2026 · Updated 3 times
Summary
This study looks at how cannabis ads that claim to help with anxiety or depression affect what people buy. About 2,000 light-to-moderate cannabis users with mild to severe anxiety or depression will shop in a realistic online store. Some see ads with mental health claims, others see warning labels. Researchers will measure total THC purchased, average potency, and number of products to see if claims increase risky buying and if warnings can reduce it.

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 could inform regulations to reduce misleading cannabis advertising and protect vulnerable consumers.
- What could go wrong
- This is an online simulation, not a real purchase setting, so actual behavior may differ. The study is observational and does not test a treatment.
