Who could benefit from this research

Could help

Adults 21 years and older who primarily use cannabis concentrates and are seeking to reduce use.

Less likely to help

Individuals who do not use cannabis concentrates or who are not seeking to reduce use may not benefit.

What this research studies

If you use cannabis concentrates and want to cut back, this study will compare a hemp-derived CBD product to a placebo to see if it helps lower use and relieve withdrawal and mood symptoms. The study uses a double-blind design so neither participants nor study staff know who gets CBD or placebo. Researchers will monitor cannabis use, withdrawal symptoms, anxiety, mood, and safety over the trial period. Participants will provide blood samples and complete questionnaires as part of regular study visits.

Why it matters

Potential benefit: If successful, the treatment could offer a widely accessible option to reduce cannabis use and improve well-being for people using high-potency concentrates.

How similar studies have gone: Prior studies suggest CBD can reduce cannabis use and related symptoms, but evidence in hemp-derived, broad- or full-spectrum CBD forms in high-potency users is limited.
