Cannabis Use Disorder Treatment Study

Treating Young Adult Cannabis Use Disorder With Text Message-Delivered Peer Network Counseling

The purpose of this study is to test a text-delivered counseling program to stop or reduce cannabis use among young adults (ages 18 to 25).

After being informed about the study and potential risks, participants will complete online screening assessments. Those who are determined to be eligible via online screening will complete a urine drug screen to confirm eligibility. Once eligibility is confirmed, participants will be randomized either to the intervention group or to the wait-list control group. Those who are randomized to the intervention group will receive the 4-week text intervention via smartphone and complete assessments (including urine drug screens) at baseline, 1 month, 3 months, and 6 months. Those who are randomized to the wait-list control group will only complete the assessments (including urine drug screens) at baseline, 1 month, 3 months, and 6 months. Participants who are initially assigned to the wait-list control group can choose to receive the text intervention once their 6-month participation is complete.
