Brief motivational mobile program for frequent or high-intensity cannabis use
Feasibility/Acceptability of a Brief Motivational Intervention Integrating Online Personalized Feedback & Tailored Text Messages for Frequent/High-Intensity Cannabis Use in Post-Legalization Landscape
This project will try a short mobile program with texts and mini-modules to help 18–29-year-olds who use cannabis frequently or high-THC products and are not in a 4-year college, compared with online psychoeducation.

What this trial studies
This randomized trial will enroll 120 young adults (ages 18–29) who live in Washington or Oregon, are not enrolled in a 4-year college, and report frequent or high-THC cannabis use. Participants will be randomized to a five-week brief motivational mHealth intervention that sends texts and offers weekly reflective mini-modules, or to an online psychoeducational attention-control program. The mHealth program prompts reflection on cannabis use, personal goals, motivations for use, perceived norms, and tracking of use, with weekly check-ins. Outcomes include program satisfaction and follow-up assessments at 3 and 6 months to measure changes in use and related behaviors.
Who should consider this trial
Good fit: Ideal candidates are 18–29-year-olds living in Washington or Oregon who are not attending a 4-year college, have email and a mobile phone, and use cannabis on 15+ days in the past month or used >60% THC products in the past month.
Not a fit: People who are pregnant or trying to become pregnant, currently in substance use treatment, or enrolled in a 4-year college/graduate program are excluded and are unlikely to benefit from this program.
Why it matters
Potential benefit: If successful, this could offer a brief, scalable phone-based program to help non-college young adults reduce frequent or high-THC cannabis use and better align use with their personal goals.
How similar studies have performed: Previous brief motivational and mobile health interventions for substance use, including alcohol and cannabis, have shown mixed but promising effects, so this approach builds on existing, partially successful work.
