Study of Changes in Health and Function After Reducing Cannabis Use in Adults with Cannabis Use Disorder

What this Trial Is About

Researchers are evaluating the effects of reducing cannabis use in adults diagnosed with cannabis use disorder CUD. The study aims to understand how decreasing cannabis consumption may improve cannabis-related problems, sleep quality, cognitive abilities, the severity of CUD, and overall quality of life. This interventional study is sponsored by the Medical University of South Carolina and focuses on adults 18 years and older with confirmed CUD. Participants will engage in an 8-week intervention combining motivational interviewing, computerized cognitive behavioral therapy CBT4CBT, and financial incentives tied to reductions in urinary cannabinoid levels. The program begins with one therapist-led motivational session followed by seven computerized CBT sessions. Financial rewards are provided contingent on lowering cannabis use as measured by urine tests. Throughout the study, participants will be monitored for changes in cannabis-related problems, sleep patterns including total sleep time and sleep stages, and various cognitive functions assessed through standardized memory and processing speed tests. The primary outcome is measured at the end of the 8-week treatment, focusing on cannabis-related problems. This study involves regular assessments and aims to observe improvements in functioning and quality of life linked to cannabis use reduction.
