Who could benefit from this research
✓Could help
Adults 21 years and older with cannabis use disorder and co-occurring depressive symptoms.
✕Less likely to help
People without cannabis use disorder or without depressive symptoms may not benefit.
What this research studies
This project focuses on adults with cannabis use disorder who also experience depression. It builds on prior findings that pregnenolone may dampen cannabis effects and improve mood, exploring its use as a dual-purpose treatment. The team at UT Southwestern will test how pregnenolone works when given to participants, monitoring safety and changes in cannabis use and depressive symptoms over time. The study uses human participants to explore a potential new medication approach for a challenging co-occurring condition. If successful, it could lead to new options for people struggling with both cannabis use and depression.
Why it matters
Potential benefit: If successful, this could provide a new treatment that helps reduce cannabis use and eases depressive symptoms for people with both conditions.
How similar studies have gone: Prior data suggest pregnenolone can influence mood and substance use, but this specific combination is being studied.
