The research team is recruiting 500 participants between the ages of 18 and 25 for a research study on brief phone-based treatment for problematic marijuana use. As part of this study, participants will complete surveys over 6 months about marijuana use, mental health, and friends. Then they will participate in either 4 weeks of text message counseling & monthly surveys OR only complete monthly surveys.

To get started, anyone who is interested must complete an initial screening to see if they are eligible at All information collected from study participants is confidential and highly protected. Participants will be compensated up to $200 over 6 months for their time and effort. To be eligible, participants:
– must be between 18 and 25 years old
– have problematic marijuana use (which will be determined by the study)
– live in Colorado or Tennessee
– and have access to a text-message capable phone.
