Supplementary Material for: Contingency Management for Cannabis Use Disorder Treatment

Introduction: Although recreational cannabis use and abuse are expressive worldwide, the comparison of worldwide used psychotherapies, such as cognitive behavior therapy, with contingency management in the treatment of cannabis use disorder remains inconclusive. Methods: We screened all articles published on MEDLINE (via PubMed) published until October 2023 and conducted a systematic review with metanalysis. Results: Sixteen studies were included, and contingency management intervention likely promotes abstinence outcomes and more negative urinalyses for adults or adolescents with cannabis use disorder. Discussion: This review provides moderate to high-quality evidence that Contingency Management can be used to treat cannabis use disorder. However, further trials need to be developed to analyze the quantity of substance use, personal achievements, and operational improvements after treatment.
