• Conditions: Cannabis Use

• Registration Number: NCT07011615
• Lead Sponsor: University of Washington

Brief Summary

The study aims to develop a novel brief motivational mobile health (mHealth) intervention for high-risk and high-intensity cannabis use for non-collegiate young adults. A total of 120 young adults (ages 18-29, not enrolled at or attending a 4-year college or university) will be randomized to receive a mHealth intervention with text messages for five weeks or to an online resource/program with psychoeducation information about cannabis. The mHealth intervention will focus on prompting the young adult to reflect on their journey with cannabis and to reflect on their personal goals and how cannabis is reflected in these goals. Personalized feedback about their patterns of use, motivations, emotions, and social connections will be integrated throughout the program. Participants will come back to the program each week to reflect on the prior week and reflect on goals for the upcoming week. All participants will complete a program satisfaction survey and complete follow-up assessments at 3- and 6-months post-program.
