What this trial studies

This study evaluates the effectiveness of an Integrative Therapy for Adolescent Cannabis Use (TIMCA), which combines Motivational Interviewing (MI), Cognitive Behavioral Therapies (CBT), and an Attachment-Based Intervention (ABI). The TIMCA will be compared to Treatment As Usual (TAU) to assess its impact on cannabis use and related psychological factors. Secondary objectives include evaluating improvements in relationship quality with parents and friends, emotional regulation strategies, and symptoms of depression and anxiety. The study aims to address the significant public health issue of cannabis use among adolescents, particularly in France.

Who should consider this trial

Good fit: Ideal candidates are adolescents aged 14 to 19 years with a diagnosis of Cannabis Use Disorder who are fluent in French.

Not a fit: Patients with acute psychiatric disorders, other substance use disorders, or those already engaged in therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly reduce cannabis use and improve emotional and relational well-being in adolescents.

How similar studies have performed: Previous studies have shown that combining MI and CBT is effective for young cannabis users, suggesting potential success for this integrative approach.
