ClinConnect Summary

This clinical trial is studying a new digital program designed to help people who are dealing with both depression and cannabis use issues. The goal is to see if this program, called Amplification of Positivity - Cannabis Use (AMP-C), is easy to use, acceptable to participants, and effective in improving mood and reducing cannabis use. Participants will be randomly assigned to either use this program or track their symptoms, and researchers will look at how well they stick with the program, their feelings of happiness, and changes in their cannabis use and depression symptoms.

To be eligible for this study, participants need to be at least 18 years old, live in the United States, and be able to read and understand English. They should also be experiencing moderate symptoms of depression and have issues with cannabis use. Importantly, they must be interested in getting help for these problems. However, individuals with certain mental health conditions like severe mood disorders or those currently in therapy will not be part of this trial. The study is not yet recruiting, but if you or someone you know fits the criteria, it could be a valuable opportunity to receive support and contribute to important research.
