ClinConnect Summary

This clinical trial is studying a new program designed to help young adults who use cannabis frequently and intensely. The goal is to see if a mobile health (mHealth) intervention, which includes sending text messages, can be a helpful way for these individuals to reflect on their cannabis use and set personal goals. The study will involve 120 participants aged 18 to 29 who live in Washington State and use cannabis regularly. Those eligible should use cannabis on 15 or more days in the past month and use it two or more times a day, or consume products with high levels of THC (more than 60%).

Participants will be randomly assigned to either receive the text message intervention or access an online educational program about cannabis. Over five weeks, participants will reflect on their cannabis use, emotions, and social connections, while also receiving personalized feedback. Everyone will complete a satisfaction survey and follow-up assessments three and six months after the program. This trial is not yet recruiting participants, and it’s important to note that individuals who are pregnant or in substance abuse treatment, or those attending a four-year college, are not eligible to participate.
